Background: Three-dimensional (3D) printing technology has rapidly emerged as a transformative tool in medicine, enabling the conversion of two-dimensional scans into highly accurate 3D models. This technology, especially when combined with artificial intelligence (AI) and advanced materials, offers numerous applications in surgical planning, simulation-based training, and patient-specific care. Methods: This review examines current literature and case studies on the use of 3D printing technology in various fields of medicine, especially in surgical specialties. Key applications include surgical planning, mock surgeries, biopsy guide creation, and customized implant fabrication across various surgical fields. Results: 3D printing is transforming surgery by enabling precise visualization of tumors and critical structures, significantly enhancing preoperative planning for conditions such as bone, soft tissue (e.g., neuroblastomas), renal, and maxillofacial tumors. In reconstruction surgeries, patient-specific 3D-printed implants ensure better anatomical compatibility, particularly in maxillofacial, neurosurgical, and vascular applications. Puncture guides improve procedural accuracy in interventions like percutaneous nephrolithotripsy. Detailed anatomical models aid in simulation-based training, increasing preparedness for complex procedures. Additionally, patient-specific implants and AI-integrated decision support systems are paving the way for more personalized and efficient surgical care. Conclusions: 3D printing technology, especially when combined with AI, is reshaping modern surgery by improving both accuracy, safety, and personalized healthcare. Its applications extend across multiple specialties, offering new possibilities in surgical planning, training, and patient-specific treatments. As AI and bioprinting continue to evolve, the potential for real-time applications, such as live-printed tissue implants and enhanced decision support, could drive the next phase of innovation in various fields.

Background/Objectives: Double ureter kidney grafts raise concerns about increased urologic complications. Limited data exist on optimal surgical management due to small sample sizes in previous reports. This study evaluated outcomes using pantaloon ureteroneocystostomy in the largest reported cohort worldwide. Research Questions: Does pantaloon ureteroneocystostomy achieve comparable outcomes to single ureter transplants? Are long-term graft survival and function equivalent? Should this technique be adopted as standard practice? Methods: This retrospective matched cohort study involves 2210 kidney transplantations (2010–2024). Twenty-six double ureter grafts underwent pantaloon ureteroneocystostomy with dual stenting. Controls matched 1:1 for donor type, era, and recipient characteristics. The primary outcome was urologic complications. Statistical analysis included Kaplan–Meier survival curves and Mann–Whitney U tests. Results: Groups were well matched (median age: 51 vs. 52 years, 50% living donors each). Urologic complications occurred in 3.8% double ureter versus 7.7% control grafts (p = 1.000), markedly lower than 15.4% reported in recent literature. The single complication was early urinary leak, surgically repaired. No late strictures developed. The 5-year graft survival was 96.0% vs. 92.3% (p = 1.000). The final creatinine was comparable (1.25 vs. 1.28 mg/dL, p = 0.891). Conclusions: The pantaloon technique achieves superior outcomes in the largest reported double ureter cohort, with complication rates lower than previously published series. These findings support adopting this standardized approach globally to expand donor criteria while maintaining excellent outcomes. Full article

Background: Hip fractures represent a major clinical challenge, particularly in elderly and frail patients, where postoperative pain control must balance effective analgesia with motor preservation to facilitate early mobilization. Various regional anesthesia techniques are used in this setting, including the pericapsular nerve group (PENG) block, fascia iliaca compartment block (FICB), femoral nerve block (FNB), and quadratus lumborum block (QLB), yet optimal strategies remain debated. Objectives: To systematically review the efficacy, safety, and clinical applicability of major regional anesthesia techniques for pain management in hip fractures, including considerations of fracture type, surgical approach, and functional outcomes. Methods: A systematic literature search was conducted following PRISMA 2020 guidelines in PubMed, Scopus, Web of Science, and the virtual library of the Hospital Central de la Defensa “Gómez Ulla” up to March 2025. Inclusion criteria were RCTs, systematic reviews, and meta-analyses evaluating regional anesthesia for hip surgery in adults. Risk of bias in RCTs was assessed using RoB 2.0, and certainty of evidence was evaluated using the GRADE approach. Results: Twenty-nine studies were included, comprising RCTs, systematic reviews, and meta-analyses. PENG block demonstrated superior motor preservation and reduced opioid consumption compared to FICB and FNB, particularly in intracapsular fractures and anterior surgical approaches. FICB and combination strategies (PENG+LFCN or sciatic block) may provide broader analgesic coverage in extracapsular fractures or posterior approaches. The overall risk of bias across RCTs was predominantly low, and certainty of evidence ranged from moderate to high for key outcomes. No significant safety concerns were identified across techniques, although reporting of adverse events was inconsistent. Conclusions: PENG block appears to offer a favorable balance of analgesia and motor preservation in hip fracture surgery, particularly for intracapsular fractures. For extracapsular fractures or posterior approaches, combination strategies may enhance analgesic coverage. Selection of block technique should be tailored to fracture type, surgical approach, and patient-specific functional goals. Full article

Facial reconstruction presents complex challenges due to the intricate nature of craniofacial anatomy and the necessity for individualized treatment. Conventional reconstructive methods—such as autologous bone grafts and prefabricated alloplastic implants—pose limitations, including donor site morbidity, implant rejection, and suboptimal aesthetic results. The emergence of 3D printing technology has introduced patient-specific implants (PSIs) that enhance anatomical fit, functional restoration, and biocompatibility. This review outlines the evolution of 3D-printed implants, key materials, computer-assisted design (CAD), and their applications across trauma, oncology, congenital conditions, and aesthetics. It also addresses current challenges and explores future directions, such as bioprinting, smart implants, and drug-eluting coatings. Full article

Background: Teaching methodology has recently undergone significant evolution from traditional apprenticeship models as we adapt to ever-increasing rates of technological advancement. Big data, artificial intelligence, and machine learning are on the precipice of revolutionising all aspects of surgical practice, with far-reaching implications. Robotic platforms will increase in autonomy as machine learning rapidly becomes more sophisticated, and therefore training requirements will no longer slow innovation. Materials and Methods: A search of published studies discussing surgeon training and computer-enhanced simulation robotics and emerging technologies using MEDLINE, PubMed, EMBASE, Scopus, CRANE, CINAHL, and Web of Science was performed in January 2024. Online resources associated with proprietary technologies related to the subject matter were also utilised. Results: Following a review of 3209 articles, 91 of which were published, relevant articles on aspects of robotics-based computer-enhanced simulation, technologies, and education were included. Publications ranged from RCTs, cohort studies, meta-analysis, and systematic reviews. The content of eight medical technology-based websites was analysed and included in this review to ensure the most up-to-date information was analysed. Discussion: Surgeons should aim to be at the forefront of this revolution for the ultimate benefit of patients. Surgical exposure will no longer be due to incidental experiences. Rather, surgeons and trainees will have access to a complete database of simulated minimally invasive procedures, and procedural simulation certification will likely become a requisite from graduation to live operating to maintain rigorous patient safety standards. This review provides a comprehensive outline of the current and future status of surgical training in the robotic and digital era. Full article

Background/Objectives: The aim of this research was to compare perioperative outcomes, functional results, quality of life, and complications between robot-assisted simple prostatectomy (RASP) and holmium laser prostate enucleation (HoLEP) as minimally invasive techniques for treating benign prostatic hyperplasia (BPH) in large prostates (>150 cm3). Methods: This retrospective, multicenter, observational study (2007–2023) included patients with >150 cm3 prostate volumes who underwent either HoLEP or robot-assisted prostatectomy. Primary outcomes: success rate (complete enucleation, without transfusion or reintervention), good postoperative quality of life (IPSS 8th question score: 0–2), and continence at 6 months (no pads). Secondary outcomes: operative and catheterization time, hospital stay, enucleated gland weight, PSA reduction, Qmax improvement, and perioperative complications. Results: We included 95 HoLEP and 50 RASP patients with similar demographics and prostate volume (HoLEP: 187.72 cm3; RASP: 203.38 cm3). The success rate (HOLEP: 83.2%; RASP: 74%), continence rate (HoLEP: 85.1%; RASP: 86%), and quality of life (HoLEP: 83.2%; RASP 94%) were similar (p = 0.275, p = 1, and p = 0.075, respectively). HoLEP had a shorter operative time (97.58 vs. 122.4 min) and catheterization duration, with similar hospitalization duration (HoLEP: 3.46 days; RASP: 4.22 days). Although there was no significant difference in enucleated gland weight, HoLEP was more efficient (1.28 g/min vs. 1.06 g/min). Complication rates were similar (HOLEP: 15.5%; RASP: 26%; p = 0.12). Conclusions: Both RASP and HoLEP are safe for treating BPH in prostates >150 cm3, reporting similar success and continence rates and good quality of life after surgery. However, HoLEP achieved results with shorter operative time and catheterization duration. Full article

Purpose: Our aim is to offer an additional surgical option for patients with rectus diastasis, with or without associated abdominal wall hernias, through a minimally invasive approach with endoscopic surgical correction, presenting a new method for abdominal contouring via minimally invasive mini-abdominoplasty (MAMI). Ideas: According to the European Hernia Society (EHS) classification for RD, a widening greater than 2 cm of the linea alba is generally considered an indication for surgical correction. Recent approaches, such as MILA and SCOLA, are indicated for patients with a body mass index (BMI) of up to 28, based solely on height and weight. However, some authors consider this insufficient for determining the best surgical indication. Despite advances in skin retraction, there is still no evidence on how these devices affect postoperative outcomes when added to these techniques, as they depend on multiple factors such as age, skin firmness, number of passes, applied energy, etc. Consequently, even patients with a BMI of up to 28 may present significant flaccidity both above and below the umbilicus, as well as poor skin quality (thin, lax, with stretch marks), making SCOLA or MILA surgery alone unsuitable due to possible skin redundancy after surgery. Similarly, even patients with a high-positioned umbilicus, moderate flaccidity, and rectus diastasis, who in the past would have been strictly indicated for abdominoplasty, may benefit from mini-abdominoplasty with a minimally invasive approach (MAMI). Discussion: The main objective of this study is to provide another surgical option for patients who would otherwise be indicated for abdominoplasty and also for those undergoing MILA or SCOLA who still require minor skin removal to enhance the surgical result. Based on our experience, mini-abdominoplasty with a minimally invasive approach (MAMI) has the potential to serve a larger number of patients, since most present degrees of skin laxity that, even after using technologies, require skin excision. In addition to complementing the results, it reduces complications, results in smaller scars, allows a better correction and visualization of the diastasis, avoids periumbilical scars, and offers faster recovery compared to abdominoplasty. Conclusions: MAMI surgery has proven to be a safe and reproducible approach for selected women who wish to restore feminine body features after pregnancy and achieve a quick recovery. It yields satisfactory esthetic results due to the minimized scar, preservation of the natural umbilical scar, and improved surgical correction of rectus diastasis. Full article

Background/Objectives: Pudendal neuralgia (PN) is a debilitating chronic pain condition resulting from injury, inflammation, or entrapment of the pudendal nerve. It significantly affects patients’ quality of life and poses challenges to treatment due to its complex etiology. Conventional therapies often provide limited or temporary relief. The impar ganglion block (IGB) has emerged as a potential intervention for managing refractory pelvic pain syndromes. This systematic review aimed to evaluate the clinical efficacy, safety, and applicability of IGB in treating patients with PN. Methods: This systematic review evaluates the efficacy and clinical applicability of IGBs in treating PN. Following PRISMA-P 2020 guidelines, a systematic search was conducted in PubMed/MEDLINE, Embase, LILACS, and Cochrane Library. Eligible studies included RCTs, observational studies, and case series assessing pain reduction and quality of life post-IGB. Non-neuropathic pelvic pain studies were excluded. The ROBVIS tool assessed the risk of bias. Results: Of 306 articles screened, 16 met eligibility criteria. Studies showed that the IGB provides significant pain relief, particularly for refractory cases. Image-guided techniques enhanced precision and reduced complications. Combination therapies with corticosteroids yielded longer-lasting analgesia. However, methodological inconsistencies and varied patient selection limited generalizability. Conclusions: The IGB is a minimally invasive, effective option for managing PN. Further high-quality RCTs are needed to standardize protocols, optimize patient selection, and evaluate long-term efficacy. A multidisciplinary approach remains essential. Full article

Background: Despite ongoing efforts to improve the pancreaticoduodenectomy technique and perioperative care, surgical site infection (SSI) remains a contributor to morbidity. Efforts to reduce SSI include the use of negative pressure wound therapy (NPWT), but studies and meta-analyses have been met with conflicting results. We aimed to provide an up-to-date large-scale cohort study to assess the impact of NPWT on SSIs. Methods: Utilizing the National Surgical Quality Improvement Program database, we included patients undergoing a pancreaticoduodenectomy between 2017 and 2021 and divided patients into the NPWT and non-NPWT cohorts. A bivariate analysis was performed to compare baseline characteristics and complication rates between the cohorts. Multivariate logistic regression analysis was performed to assess the independent effect of NPWT on 30-day serious complication, 30-day mortality, and the development of deep or superficial SSI. A priori sensitivity analyses were performed in high-risk and malignancy cohorts. Results: Of the 14,044 included patients, 1689 (12.0%) patients had a prophylactic NPWT device, while 12,355 (88.0%) did not. Patients were more likely to have NPWT if they had higher ASA scores, had diabetes, were dialysis-dependent, or had a hard pancreas, but they were less likely if they were a smoker, had steroid use, or had a bleeding disorder. Most complications occurred similarly between the two cohorts, including superficial and deep SSI, but NPWT patients had a longer length of stay (10.4 d vs. 9.5 d, p < 0.001) and higher organ space SSI (22.6% vs. 17.4%, p < 0.001). Following multivariable modeling to control for demographic differences, NPWT was not independently associated with a difference in likelihood of SSI (aOR 0.94, p = 0.691) or serious complications (aOR 0.958, p = 0.669). Furthermore, the sensitivity analyses of both high-risk and malignant subgroup also did not see an independent association of NPWT on the rate of SSI (aOR 0.98, p = 0.898 and 0.96, p = 0.788, respectively). Conclusion: NPWT is used infrequently and is not significantly associated with improved outcomes including in the high-risk or malignant subgroups based on multivariable analysis for surgical site infections nor did it improve the outcomes of 30-day serious complications in these subgroups. Considering this and other studies showing the limited benefit of NPWT in all-comers and in high-risk cohorts, it remains unclear whether NPWT offers benefits following PD. Full article

Background: Patients with no-option chronic limb-threatening ischemia (NoCLTI), lacking suitable distal arteries for conventional revascularization, face major limb amputation. The 1-year mortality rate after major amputation is 48.3%, increasing to 70.9% in 3 years. Open deep venous arterialization (DVA) offers a promising alternative for limb salvage, achievable through open, endovascular, or hybrid approaches. We aim to provide a comprehensive, step-by-step guide to performing open DVA in NoCLTI patients, addressing preoperative and postoperative considerations as well as the technical details of the procedure. Methods: Patient selection for open DVA focuses on individuals with NoCLTI at high risk for amputation. Preoperative assessments include evaluating risk factors, determining limb threat severity using the Wound, Ischemia, and foot Infection (WIfI) score, and mapping anatomical patterns via the Global Limb Anatomic Staging System (GLASS). The procedure involves identifying the target artery using Doppler ultrasound, performing microdissection to expose the artery and vein, ligating proximal vein branches, and creating a side-to-side anastomosis. Venous valves are disrupted with a valvulotome to allow antegrade flow. A proximal bypass graft may be applied if necessary. Results: Postoperatively, patients are monitored for 2–4 days with frequent Doppler assessments. Anticoagulation therapy begins with a heparin drip, transitioning to oral agents and/or dual antiplatelet therapy. Wound care includes deferred debridement for 2–4 weeks and may involve negative-pressure therapy. Follow-up involves weekly visits for the first month, and then at 3 months, and every 6 months thereafter, with surveillance using transcutaneous oxygen measurement, the toe–brachial index, and arterial duplex ultrasound. Conclusions: Open DVA represents a viable limb salvage option for patients with NoCLTI, potentially avoiding major amputations and improving quality of life. Success depends on careful patient selection, a meticulous surgical technique, and comprehensive postoperative care. Full article

Cytoreductive surgery in the context of a multidisciplinary approach, including adjuvant and neoadjuvant therapy (when indicated), aims ideally to obtain complete resection and represents the cornerstone for long-term survival in patients with advanced ovarian cancer (AOC). Positive lymph nodes are a relatively frequent appearance during cytoreductive surgery for AOC and a widely accepted negative prognostic factor for long-term survival. However, the impact of systematic pelvic and paraaortic lymph node dissection (SPALND) on early and long-term outcomes in patients with cytoreductive surgery for AOC and no suspected positive lymph nodes remains highly controversial. The paper aims to review the relevant scientific literature exploring the role of SPALND in patients with AOC, focusing on peer-reviewed papers published before and after the LION study’s data release. The LION trial represents the only level 1 evidence study providing no scientific arguments for the routine using SPALND in AOC as part of complete cytoreductive surgery in patients without clinical suspicion of positive lymph nodes. The LION trial changed the practice of surgeons regarding SPALND, and current essential guidelines do not recommend it as a routine. Furthermore, SPALND may increase morbidity rates of cytoreductive surgery for AOC and negatively impact the patient’s quality of life. A comprehensive pelvic and paraaortic lymph node assessment is mandatory before and during cytoreductive surgery for AOC for proper disease staging, adequate management, and long-term prognosis. Further research is needed to identify patients with AOC at high risk for lymph node metastases; this group might benefit from SPALND. Full article

Background/Objectives: Popliteal artery injury is a rare but devastating complication of knee dislocations, significantly increasing the risk of limb ischemia, amputation, and poor functional outcomes if not promptly managed. This systematic review primarily evaluates the functional outcomes associated with this injury but also reviews current research on diagnostic modalities and treatment strategies to provide a comprehensive understanding of this severe orthopedic and vascular injury. Methods: A systematic search of PubMed, in accordance with PRISMA Guidelines, identified 144 studies, of which 13 full-text articles were assessed for eligibility after excluding 131 during the title and abstract screening. Six studies were excluded due to missing vascular injury or functional outcome data or being written in a foreign language, leaving seven studies for inclusion. These studies were predominantly retrospective, focusing on knee dislocations with popliteal artery injury and reporting validated functional outcomes such as the Lysholm and International Knee Documentation Committee (IKDC) scores. The data were synthesized narratively due to heterogeneity in the study designs, interventions, and outcome reporting. Results: Patients with vascular injuries consistently demonstrated poorer functional outcomes compared to those without, with mean or median Lysholm and IKDC scores consistently being lower than non-vascular injury patients. Increased BMI, delayed intervention, and multi-ligamentous injury were associated with worse outcomes, highlighting the importance of timely surgical management. Early repair and grafting techniques improved functional recovery, while diagnostic modalities such as Doppler ultrasound and CT angiography showed high sensitivity in detecting vascular injury. Complications included limb ischemia, prolonged rehabilitation, and amputation, often linked to delayed diagnosis. Conclusions: Knee dislocations with popliteal artery injury require rapid diagnosis and early surgical intervention to optimize functional outcomes and reduce complications. Standardized outcome measures and high-quality prospective research are needed to refine management strategies and address patient-specific factors like BMI. Full article

The aim of the present systematic review was to evaluate the feasibility and effectiveness of TAI in patients with significant LARS symptoms. Methods: We performed a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and guidelines in addition to the Cochrane Handbook for Systematic Reviews of Interventions. The protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42023436839). The risk of bias was assessed using a modified version of the Downs and Black checklist. The main outcome was improvement in low anterior resection syndrome after TAI assessed by change in LARS score. Results: After an initial screening of 3703 studies, 9 were included and underwent qualitative synthesis (among them, 3 were randomized clinical trials). All studies recorded an improvement in LARS score following TAI procedure and almost all studies showed an improvement in other bowel function outcomes (Memorial Sloan Kettering Cancer Center Bowel Function Instrument (MSKCC BFI, ), Cleveland Clinic Incontinence Score (CCIS), visual analog scale (VAS), Cleveland Clinic Florida Fecal Incontinence Score (CCFFIS), fecal incontinence score (FI score), Obstructed Defecation Syndrome (ODS) score) and quality of life (QoL) scores. The discontinuation rate ranged from 0% to 41%. The rate of adverse events was high (from 0 to 93%); moreover, no uniformity was found in the various protocols used among the different studies. Conclusions: The results of this review show that TAI is effective in the treatment of LARS, improving the LARS score, the other bowel function outcomes and the QoL scores. The absence of a treatment protocol validated by the scientific community is reflected in the high disparity in terms of adverse events and discontinuation of therapy, in addition to representing an intrinsic limitation to the study itself.

Introduction: Metatarsalgia is a very common pathology in podiatric consultations, whose main aetiological factor is biomechanical alterations. Given the failure of conservative treatments, minimally invasive osteotomies of the distal metatarsal are becoming more popular, providing comparable results to open surgical techniques and with a lower rate of complications. Objectives: To determine clinical improvement and patient satisfaction after minimally invasive distal metatarsal osteotomy (DMMO) as a surgical treatment for central metatarsalgia at present. Methodology: The databases used for this systematic review were PubMed, Scielo, Cochrane Library, WOS and Scopus. We included articles that studied the efficacy of DMMO for primary metatarsalgia and excluded studies whose patients had more than one pathology or used other surgical techniques. Results: We identified 10 articles, 5 prospective studies, 4 retrospective studies and 1 cross-sectional, non-randomized, analytical study published between 2015 and 2021. The total number of subjects was 366, with a mean age of 61 years. The majority of subjects were women. They presented with symptomatology compatible with primary metatarsalgia for a minimum of 6 months and had failed conservative treatment. Conclusions: DMMO osteotomies for central metatarsals offer excellent post-surgical results for the treatment of central metatarsalgia in the assessment scales (AOFAS, MOXFQ etc.) of the articles analyzed and therefore an evident clinical improvement with benefits in terms of MTF mobility and reduction of surgical time, as well as a high degree of satisfaction in the patients who received this intervention that can be considered as excellent.

Background/Objectives: Acute ruptures of the Achilles Tendon (AT) are common injuries in the active population, in particular among men aged 30 to 50. Full functional recovery after this kind of injury is long and challenging and nowadays there is no universal “gold standard” strategy when dealing with them. Methods: When it comes to surgical treatment, various techniques have been described: in case of a typical lesion at the midportion of the tendon (which is the most common type), the basic principle of surgical repair is the end-to-end suture of the tendon stumps. The AT (“calcaneal tendon” according to the International Anatomical Terminology) is the strongest tendon of the human body, it is the conjunct tendon of the two Gastrocnemii Muscles and the Soleus Muscle and has a well-recognizable twisted structure: the subtendon from the Medial Head of the Gastrocnemius attaches postero-laterally on the calcaneal tendon footprint, the subtendon from the Lateral Head of the Gastrocnemius attaches antero-laterally and the subtendon from the Soleus attaches medially, therefore creating a 90° twist of the tendon structure. Results: the twisted structure of the human AT is of central importance to its biomechanics, since it gives the tendon a higher resistance to deformation and concurs in supination of the subtalar joint during gait. Conclusions: given the abovementioned anatomical and biomechanical premises, we believe that the restoration of the subtendons anatomy can lead to a better functional recovery of the Triceps Surae—Achilles Tendon complex, therefore we recently decided to adopt for open surgical repair the Direct Anatomical Reconstruction of the Achilles Tendon, which we describe in the present article.

Background/Objectives: Temporary artery ligation or compression is commonly used to reduce intraoperative blood loss in various surgeries, including uterine procedures. In head and neck surgery, the external carotid artery (ECA) typically branches into eight vessels, supplying most of the head and neck except for the brain. Severe and uncontrolled bleeding can occur if these branches are inadvertently damaged during surgery. However, limited research exists on temporary arterial ligation during head and neck surgeries. This study aimed to evaluate the effects of temporary ECA restriction and internal maxillary artery (IMA) ligation on minimizing intraoperative blood loss during head and neck surgery. Methods: This study involved 25 patients with terminal-stage maxillary tumors who underwent total maxillectomy. The effectiveness of IMA ligation and ECA restriction using a Rummel tourniquet in controlling intraoperative bleeding was compared. Results: The average blood loss was significantly lower in the ECA restriction (467 mL) and IMA ligation (461 mL) groups than in the control group (794 mL). However, no significant difference was observed between the IMA ligation and ECA restriction methods. Conclusions: Overall, our results suggest that either method is effective; however, ECA restriction is preferred for tumors involving the infratemporal fossa. Full article

(1) Background: The aim of this study was to investigate potential translational factors for optical 3D reconstruction in an in vivo setting using a newly developed computerized bowel length measurement system (BMS) as a real-time application. (2) Methods: The BMS was evaluated in an in vivo porcine experiment for the influence of light source power (Watt), laparoscope-to-bowel distance (cm), bowel rotation, image background, and surgical objects in the image. Endpoints were robustness, calculated as success rate (SR) in percent, and accuracy, defined as relative error (RE) in percent of BMS measurement result to ground truth. (3) Results: A total of 1992 bowel measurements were performed on n = 7 pigs using the BMS. Bowel measurements were robust and accurate regardless of light source power, at a laparoscope-to-bowel distance of 5 cm (SR 100%, RE 18 ± 38.5%), when the small bowel was aligned horizontally (SR 100%, RE 7.3 ± 36.2%) or in the image background (SR 100%, RE 15.2 ± 23.4%), and when no additional instruments were in the image. (4) Conclusions: Applications based on optical 3D reconstruction are feasible for intraoperative use and could enable quantitative laparoscopy. Full article

Introduction: Femoral neck fractures pose significant health risks, particularly in the elderly population, leading to mortality, morbidity, and decreased quality of life. Surgery is the preferred treatment to restore function and alleviate pain, with options including total hip arthroplasty (THA) and hemiarthroplasty (HA). However, clinical guidelines for selecting surgical procedures remain heterogeneous, prompting the need for further investigation into treatment trends and influencing factors. Methods: Data from the NIS database spanning 2016–2019 were analyzed, focusing on patients diagnosed with intracapsular femoral neck fractures and undergoing THA or HA as primary in-hospital surgeries. Advanced statistical analyses using SPSS and MATLAB were conducted to identify trends and factors influencing surgical choices. Results: Comorbidity profiles varied significantly between HA and THA patients, with specific conditions such as Alzheimer’s disease showing higher prevalence in HA patients. Demographic differences included a higher proportion of females and Medicare-insured individuals in the HA group. Racial disparities were observed, with differences in surgical preferences among various ethnic groups. THA adoption gradually increased over the study period, indicating a shift in surgical priorities. Additionally, THA patients tended to be younger on average compared with HA patients. Conclusions: This study highlights evolving trends in surgical management for femoral neck fractures and identifies factors influencing treatment decisions in our cohort. Understanding these trends and disparities is crucial for optimizing patient care and informing future clinical guidelines. Further research should focus on assessing different surgical approaches’ long-term outcomes and cost-effectiveness. Full article

Introduction: Mastectomy skin necrosis (MSN) is a common complication occurring in up to 50% of patients. In patients with risk factors for poor wound healing such as immunosuppression, prior radiotherapy (XRT), and high body mass index (BMI > 30.0), this number is even higher. MSN can lead to infection, loss of reconstruction, poorer aesthetics, and most ominously, delay in adjuvant cancer therapy. Instead of forgoing reconstruction in these patients, adjunctive therapies to optimize wound healing are necessary. The purpose of this study is to introduce the use of cryopreserved umbilical tissue (vCUT) as an adjunct therapy for high-risk-wound-healing immediate breast reconstruction (IBR) patients. Methods: All patients who underwent breast reconstruction with vCUT as an adjunctive therapy were identified and retrospectively analyzed. Results: Seven patients who underwent breast reconstruction with vCUT placement were identified. These patients had risk factors for delayed healing, such as obesity, immunosuppression, and/or prior XRT. The mean post-operative follow-up was 252 days (range 183–287). Four out of seven patients demonstrated post-operative complications: two out of seven developed seromas, two out of seven developed wound dehiscence, two out of seven developed infection, two out of seven developed MSN, and two out of seven lost their reconstruction. Conclusion: As undergoing IBR leads to improved mental health and superior aesthetic outcomes, efforts to expand current indications for safe IBR to traditionally poorer reconstructive candidates are imperative. The results of this case series demonstrate vCUT as a promising novel adjunctive tool in the reconstructive surgeons’ armamentarium in managing the less ideal reconstructive breast candidate.

Pelvic inflammatory disease is an infectious condition affecting women’s upper genital tract, including the uterus, fallopian tubes, and ovaries. It primarily arises from an infection that spreads upward from the lower genital area. The relationship between chronic pelvic pain and coexisting conditions is a key focus in its diagnosis and treatment. This type of pain is also considered a form of reflex dystrophy, involving both neurological and psychological components, the first line treatment consists in antibiotherapy. For patients with complex or severe pelvic abscesses, surgical intervention may be considered in selected cases. The primary surgical techniques employed are open and laparoscopic surgery, both aimed for abscess removal. MRI or Doppler ultrasonography may be employed when there is a suspicion of adnexal torsion, adenomyosis or deep pelvic endometriosis, especially if the ultrasound results are unclear or inconclusive Laparoscopic surgery has increasingly become favored by both healthcare professionals and patients. Moreover, laparoscopy has emerged as the most valuable tool for diagnosing chronic pelvic pain. The approach to treating pelvic abscesses in women of reproductive age depends greatly on clinical assessments, individual patient factors, and the desire to preserve fertility. However, laparoscopy may present technical difficulties in patients with severe pelvic abscesses, particularly those with extensive adhesions or a closed-off pelvic area, requiring advanced surgical expertise. Women with associated conditions such as endometriosis often experience a more severe form of pelvic inflammatory disease, which is less responsive to antibiotics and more frequently requires surgical resolution. The surgical treatment should be performed individualized to the clinical condition of the patient and the time of intervention must be carefully chosen. Full article

Background: In the landscape of thoracic surgery, innovation continually drives progress, offering novel approaches to address complex pathologies while prioritizing patient well-being. Dual-port robotic-assisted thoracic surgery (DRATS) represents a new frontier in this evolution. In this report, we describe our experience with the fully dual-port robotic-assisted thoracic surgery (F-DRATS) approach for segmentectomy with the indocyanine green intersegmental plane identification. Methods: We define as F-DRATS the robotic thoracic surgery performed by two intercostal incisions without rib spreading, using the robotic camera, robotic dissecting instruments, and exclusively robotic staplers. We herein describe our F-DRATS approach in lingulectomy and lymphadenectomy of stations 5, 6, 7, and 10 using the da Vinci Surgical System. Results: The patient’s postoperative course was uneventful with the chest tube removed on the second postoperative day. The final pathological analysis confirmed a low-grade malignant potential adenocarcinoma, with a main diameter of 1.1 cm, at 3 cm from the lung margins. Conclusions: This is the first description in the literature of a F-DRATS lingulectomy with ICG intersegmental plane identification. Full article

The spine community is continuously adding to its armamentarium of intraoperative techniques for visualization and instrumentation of the spine. Recently, three-dimensional printed spine models were introduced for use in preoperative planning, surgical simulation, and intraoperative guidance. We present a 14-year old African male with congenital kyphoscoliosis, small stature, an obvious gibbus deformity and coronal imbalance, who underwent a three-staged posterior surgical correction procedure, during which a 3D-printed spine biomodel was utilized for better appreciation of his complex spinal deformity patho-anatomy. During the first stage of the procedure, he developed diminished lower extremity motor strength bilaterally and bowel/bladder control, but, following his third stage procedure and with focused rehabilitation efforts, he has regained full control of his bowel and bladder function, and is able to ambulate and perform activities of daily living independently, albeit still requiring intermittent walking support with a single forearm crutch due to residual left leg weakness. The 3D spine biomodel functioned successfully as a valuable tool and surrogate anatomic blueprint for the surgeons, enabling adequate appreciation of the complex bony anatomy which could not be easily resolved on the conventionally available imaging modalities, intraoperative navigation or robotic platform. Theoretically, up to $2900 USD in savings, translated from the mean estimated time saved per procedure with the use 3D-printed spine models has been proposed in some studies. Therefore, 3D-printed spine models have utility in complex spinal deformity correction surgery. Full article

Background: anatomic lung segmentectomies allow accurate resection of pulmonary lesions, maximizing healthy tissue preservation, and reducing unnecessary loss of lung function. In this setting, accurate preoperative planning is crucial. We present our early experience, detailing the successful use of 3D-CT models in tailoring therapeutic strategies for three patients undergoing complex anatomical lung resections due to neoplastic diseases. Case Presentation: (1) 60-year-old male patient with significant pulmonary functional impairment underwent successful right lower lobe bi-segmentectomy (S7–S8) for carcinoid, stage IA1. (2) 65-year-old female patient with previous left lung resection and functional impairment underwent uneventful right upper lobe bi-segmentectomy (S1–S2) for double lung adenocarcinoma, stage IIb. (3) 67-year-old male with previous ipsilateral lung resection underwent left lower lobe segmentectomy (S8) for metastatic colic adenocarcinoma without any complications. Conclusion: 3D-CT imaging, particularly through VPTM platform, enhances the safety and precision of complex lung segmentectomy, providing a valuable surgical map for improved outcomes. Full article

Background and Objectives: Thoracolumbar fracture–dislocations (AO type C) are rare injuries that occur due to high-energy trauma, and the result is translational and rotational instability of the spinal column and neurological impairment. Several reduction maneuvers have thus far been published, each of which can be of use in certain specific situations. We developed a modification to the previously described reduction technique. Materials and Methods: This is a case study on the management of thoracic AO type C fracture–dislocations managed with a modified reduction technique. The success of the reduction and intraoperative iatrogenic complications such as dural tear and screw pull out were the outcomes analyzed. Results: A total of four cases were successfully reduced with this described reduction technique. We did not note any complications such as a dural tear or screw failure with this modified reduction technique. Conclusions: A modification to the reduction technique employed in the management of thoracic fracture–dislocations resulted in a successful reduction without the risk of iatrogenic complications due to the reduction maneuver.

Background: An association between increased postoperative glycemic variability (GV) and inferior postoperative outcomes following hip arthroplasty procedures has been previously reported. However, the utilization of the GV to project surgical outcomes following the fixation of hip fractures has not been well established. The aim of this study is to assess the association between the postoperative GV of patients with diabetes mellitus (DM) and surgical outcomes following the fixation of a hip fracture. Methods: This is a retrospective analysis of 3117 consecutive cases of patients who underwent the fixation of hip fractures between 2011 and 2020. Patients with a DM diagnosis who had ≥3 postoperative glucose measurements during the first week after surgery and had a minimum of one-year follow-up were included. The coefficient of variation (the ratio of the standard deviation to the mean) was utilized to assess the GV. The final study population included 605 patients who were divided into three groups according to the extent of their GV. Short- and mid-term outcomes, including mortality, reoperations, readmissions, and postoperative infection rates were compared between the groups. Results: There was a non-significant trend towards increased rates of mortality (p = 0.06), readmissions (p = 0.22) and postoperative infections (p = 0.09) in the high GV group. The rate of revisions at the latest follow-up was significantly higher in the high GV group when compared to the two other groups (p = 0.04). Conclusion: For diabetic patients undergoing hip fracture fixation, a higher GV in the postoperative period was associated with increased rates of all-cause revision surgery and may be associated with increased mortality, readmission rates, and surgical site infections. Glucose levels of diabetic patients should be meticulously monitored and controlled in the postoperative period in an effort to contain the sequelae associated with elevated GV and to identify patients in need of closer observation and follow-up.

We report a case in which a 74-year-old man suffering from esophageal achalasia complicated with epiphrenic esophageal diverticulum was successfully treated with a simultaneous laparoscopic surgery. The gentleman was referred with symptoms suggestive of a passage disorder in the lower esophagus for the past 5 years. Esophagogastroduodenoscopy demonstrated an epiphrenic diverticulum at the left wall of the lower esophagus, and esophagography led to the suspicion of a combined esophageal achalasia. A simultaneous laparoscopic surgery with an abdominal approach was performed in which, following the opening of the esophageal hiatus, the diverticular wall was separated from the mediastinal organs and diverticulectomy was performed with linear staplers. After Heller’s myotomy, Dor’s fundoplication was subsequently performed in which both the incisional line of muscle layer and the suturing line of diverticulectomy were wrapped by the fornix of the stomach to make up for the wall strength and avoid the suture leakage. It was theoretically considered logical and effective to reinforce this vulnerable site with Dor’s fundoplication. He had an uneventful recovery and a rapid relief from symptoms following surgery.

Introduction: Sacral fractures are rare but are increasing in incidence among trauma patients. They are associated with a wide variety of complications, most commonly neurologic defects. Case Report: A 59-year old woman initially underwent open reduction internal fixation (ORIF) for a sacral fracture, after which the patient developed an infection, wound complications, and hardware failure. The revision of the iliosacral screws proved challenging in that the standard screw and washer could not achieve sufficient compression of the fracture. Therefore, a modified midfoot mesh plate was cut to size and used as a washer to gain more surface area, achieving fixation. The plate was applied laterally and cut to cover as much surface area as possible without unnecessary bony overhang. A trans-iliac trans-sacral screw was then inserted in the standard fashion, thus allowing the plate to act as a washer. This resulted in an excellent outcome with appropriate fracture healing. Conclusion: We describe the case of an iliosacral screw revision in which a modified midfoot mesh plate was used as a washer. This resulted in appropriate fixation in the revision settings. The principles described to achieve this fixation can be broadly applied in the setting of orthopedic fractures. Full article

Patellar fractures represent approximately 1% of all fractures and the pattern is influenced by the quality of the bone and the energy of the trauma. Transverse fractures are associated with extensor mechanism failure and interruption of joint congruence. Patellar fractures are generally fixed using tension band principles, through K-wires and metal cerclage. The tension band was conceived to transform the considerable tensile force applied to the patella into a compressive one to obtain a stable fixation. The use of metal implants might be associated with a significant discomfort, mostly related to the irritating action of K-wires and cerclage on the surrounding soft tissues, often leading to the need for implant removal. Therefore, we introduced an original technique for fix patellar fractures by using only a non-adsorbable braided polyblend suture. Postoperative care included progressive range of motion recovery using an articulated knee brace and a specific protocol. The suture-only tension band technique seems to be a useful technique in terms of complications and reoperation rate while allowing secure and early mobilization. Full article

Background: The arthroscopically assisted stabilization of AC joint dislocations with a suture button system is an established procedure that is widely and successfully used in everyday practice. The main advantages of this one-step method are the minimally invasive procedure and the anatomical reconstruction of the ruptured coracoclavicular ligaments with a permanent implant. With this technical note study, for the first time, the new method of navigated suture button implantation in everyday clinical practice is described with the future goal of further reducing invasiveness and increasing precision. Materials and Methods: The surgical technique is explained using precise descriptions and illustrations, photos, X-rays, and 3D reconstructions based on clinical cases. The step-by-step system setup and patient positioning, AC joint reduction and retention, 3D scan and drill tunnel planning, stab incision and Kirschner wire navigation, and cannulated drilling and implant positioning, as well as closure and documentation are described in detail. Results: The standard coracoclavicular stabilization of AC joint dislocations with the 3D C-arm navigated suture button method is described in detail. Furthermore, the feasibility of an additive horizontal acromioclavicular suture cerclage, the implantation of an additional coracoclavicular suture button system, and the single-stage cannulated screw fixation of non-displaced fractures is demonstrated. Conclusion: The navigated suture button method aims to be simple, safe, minimally invasive, and precise. Prospective clinical studies with a long follow-up should be carried out to determine the clinical and radiological outcome in comparison with current methods. Full article

Acute bowel ischemia is a life-threatening abdominal emergency. In many patients, percutaneous endovascular repair of visceral arteries in an antegrade direction across occluding lesions is challenging and sometimes not possible. We present the case of technically successful percutaneous retrograde recanalization of an occluded superior mesenteric artery in a critically ill 82-year-old patient. The superior mesenteric artery was recanalized via the branches of the celiac trunk; the guidewires were navigated to the target artery through the gastroduodenal and pancreaticoduodenal arteries. Retrograde percutaneous recanalization of the superior mesenteric artery is technically feasible, even in hemodynamically unstable patients. Full article

Focused parathyroidectomy is the preferred surgical method for treating primary hyperparathyroidism (pHPT) sustained by the pre-operatively well-localized parathyroid adenoma. We aimed to compare the effectiveness, safety, and short-term clinical outcome of minimally invasive video-assisted parathyroidectomy (MIVAP) in locoregional anaesthesia (LA) vs. general anaesthesia (GA) by means of propensity score matching (PSM) analysis. Retrospective research of patients who underwent MIVAP between January 2014 and December 2022 was carried out. Patients were divided into two groups based on the anaesthesiologic procedure (LA vs. GA). Overall, 553 patients underwent MIVAP. After PSM, 115 patients in the LA group and 230 patients in the GA group were included. MIVAP under LA was associated with shorter median operative time (16 vs. 35 min, p < 0.001), shorter median operative room occupation time (44 vs. 73 min, p < 0.001), and lesser median post-operative visual analogue scale pain, with comparable post-operative hospital stay and complication rate. MIVAP under LA is a safe and feasible procedure with significant advantages over GA in terms of post-operative pain and operative room occupation time. This last step can finally result in more efficient utilisation of the operative room and the health care system’s resources. Full article

Background. Knee and hip arthroplasty are two of the most frequently performed procedures in orthopaedic surgery. They are associated with positive patient-reported outcomes and significant improvements in quality of life for patients. Despite this, there may be room for further progress by quantifying functional improvements with gait analysis. Our study therefore aims to characterise the disease-specific gait pattern of participants with knee and hip osteoarthritis undergoing total joint replacement using a single chest-based wearable sensor. Methods. Twenty-nine participants awaiting total hip replacement and 28 participants awaiting total knee replacement underwent three-dimensional motion analysis with inertial wearable sensors. These gait metrics were then compared with 28 healthy controls of similar ages. Differences in gait metrics were evaluated using a T-test. The participants were recruited through a single centre to participate in this cross-sectional observational study. Participants with osteoarthritis severity sufficient to warrant surgical intervention were considered for inclusion in our study. The participants were instructed to walk 15–120 m in a hospital environment while fitted with a chest-based wearable sensor. Results. In total, three domains were evaluated, including spatiotemporal, variability and asymmetry parameters. There were marked variations in the gait asymmetry parameters and step length variation in both the hip and knee osteoarthritis patients compared with the healthy controls. The magnitude of gait deterioration in terms of step length asymmetry was greater on average in the hip osteoarthritis group than the knee group. The hip osteoarthritis (+180%, p < 0.001) and knee osteoarthritis (+129%, p = 0.001) groups demonstrated marked differences in step length asymmetry. Discussion. A single chest-based sensor was found to be capable of detecting pathological gait signatures in osteoarthritis patients when compared with age-matched controls. Future studies should compare pre- and postoperative changes to disease-specific gait impairments to validate the use of wearable sensors as a clinical adjunct. Full article

This study aimed to evaluate the safety and efficacy of a novel Poly-Ether-Ether-Ketone (PEEK) expandable vertebral body replacement (VBR) for anterior cervico-thoracic vertebral column reconstruction in patients with metastatic, traumatic, or degenerative diseases. Radiographic and clinical outcomes, as well as complication rates, were analyzed in a retrospective analysis of 28 patients (61 ± 13 years; 64% female) who underwent an anterior cervical corpectomy and fusion (ACCF) with the Expandable Corpectomy Device (ECD) from DePuy/Synthes (2011–2020). Correction of the bisegmental kyphotic angle (BKA) was chosen as the primary outcome. Bony fusion, loss of device height, and implant subsidence were evaluated additionally. Clinical outcome was assessed using Odom’s criteria, the numerical pain rating scale (NRS), the American Spinal Injury Association Impairment Scale (AIS), and the Karnofsky Performance Status Scale (KPSS). Our study found a significant improvement in the BKA (12.3° ± 9.6°; p = 0.0002) at the last follow-up with no statistically relevant loss of device height (p = 0.96) or implant subsidence (p = 0.99). Successful bony fusion was observed in all patients. The KPSS significantly improved in patients with a tumorous disease at the time of discharge (p = 0.0009), and the sensation of pain showed significant improvement at six months post-operatively and at the final follow-up (p = 0.004; p = 0.021). However, four patients needed further secondary posterior stabilization, and one ECD was explanted due to a severe surgical site infection after an accidental esophageal lesion. In conclusion, the ECD proofed the radiographic stability for the anterior column reconstruction of the cervico-thoracic spine with significantly improved clinical outcome. Full article

Background: The aim of this study was to identify the incidence of early mechanical failure in the first post-surgical year in patients who had undergone spinal surgery and to assess the related risk factors. Methods: A retrospective observational study was conducted examining all patients who consecutively underwent arthrodesis surgery. The incidence of postoperative mechanical failure during the first year was calculated as the primary outcome. Results: A total of 237 patients were identified for statistical analysis. The median age of the group of patients was 47 years (IQR of 44), and 66.6% were female. The incidence of mechanical failure in the first postoperative year was 5.1% overall, with 12 events, and the median time between surgery and the need for revision surgery was 5 months (IQR = 7.75). ASA score (OR = 2.39; p = 0.134), duration of the surgical procedure (OR = 1.27; p = 0.118), and inability to walk at discharge (OR = 7.86; p = 0.007) were independent risk factors associated with the mechanical failure. Conclusions: A higher ASA score and longer duration of surgery were risk factors for mechanical failure in the first year in patients who had undergone spinal surgery and must be carefully considered when planning spinal surgery. Early recovery of ambulation must be encouraged to prevent mechanical failure. Full article

The Ex Utero Intrapartum Treatment (EXIT) procedure has long been an invaluable tool in managing complex fetal conditions requiring airway interventions during the transition from intrauterine to extrauterine life. This technical note offers an in-depth examination of the EXIT procedure, emphasizing the refinements and innovations introduced at our center. The technique focuses on meticulous preoperative assessment and uses distinctive techniques and anesthetic methodologies. A multidisciplinary team assembles to plan the EXIT procedure, emphasizing patient communication and risk discussion. Our technique involves atraumatic access to the uterine cavity, achieved through the application of a uterine progressive distractor developed for this purpose. Following the use of this distractor, vascular clamps and a stapling device (Premium Poly Cs-57 Autosuture®, Medtronic) are employed. Our anesthetic approach employs general anesthesia with epidural catheter placement. Maternal operation involves low transverse laparotomy and intraoperative ultrasonography-guided hysterotomy. Fetal exposure includes gentle extraction or external version, ensuring airway access. After securing fetal airway access, umbilical cord clamping and maternal abdominal closure conclude the procedure. By revisiting the core principles of EXIT and incorporating center-specific advancements, we enhance our understanding and technical expertise. To our knowledge, this is the first time a detailed description of the technique has been published. Full article

Background: Outcome measurement in lumbar surgery is traditionally performed using patient questionnaires that may be limited by subjectivity. Objective gait analysis may supplement patient assessment but must be clinically viable. We assessed gait metrics in lumbar spine patients pre- and postoperatively using a small and lightweight wearable sensor. Methods: This was a prospective observational study with intervention including 12 patients undergoing lumbar spine surgery and 24 healthy controls matched based on age and sex. All the subjects underwent gait analysis using the single-point wearable MetaMotionC sensor. The lumbar spine patients also completed traditional patient questionnaires including the Oswestry Disability Index (ODI). Results: The ODI score significantly improved in the patients from the baseline to six weeks postoperatively (42.4 to 22.8; p = 0.01). Simultaneously, the patients demonstrated significant improvements in gait asymmetry (asymmetry in step length, swing time, single support time, and double support time, by 17.4–60.3%; p ≤ 0.039) and variability (variability in gait velocity, step time, step length, stance time, swing time, single support time, and double support time, by 21.0–65.8%; p ≤ 0.023). After surgery, changes in most spatiotemporal (gait velocity, step length, stance time, swing time, and single limb support time) and asymmetry (asymmetry in step time, stance time, swing time, and single limb support time) metrics correlated strongly (magnitude of r = 0.581–0.914) and significantly (p ≤ 0.037) with changes in the ODI. Conclusions: Gait analysis using a single-point wearable sensor can demonstrate objective evidence of recovery in lumbar spine patients after surgery. This may be used as a routine pre- and postoperative assessment during scheduled visits to the clinic. Full article

Background: Although robot-assisted laparoscopic surgery has become more in popular, it remains unclear what clinical advantages it offers over conventional laparoscopic surgery. Objective: This (systematic) umbrella review aims to synthesize and compare the clinical outcomes of robot-assisted laparoscopic surgery versus conventional laparoscopic surgery. Methods: A systematic literature search was conducted in PubMed and Scopus. All systematic reviews and meta-analyses published in the past five years that compared the clinical outcomes for cholecystectomy, colectomy, hysterectomy, nephrectomy, and/or prostatectomy were included. The quality of all included reviews was assessed with the AMSTAR 2 quality assessment tool. Each review’s study characteristics and primary sources were extracted, along with the quantitative and qualitative data for blood loss, rate of conversion to open surgery, hospitalization costs, incisional hernia rate, intraoperative complication rate, postoperative complication rate, length of hospital stay, operative time, readmission rate, and wound infection. Results: Fifty-two systematic reviews and (network) meta-analyses were included in this umbrella review, covering more than 1,288,425 patients from 1046 primary sources published between 1996 and 2022. The overall quality of the included reviews was assessed to be low or critically low. Robot-assisted laparoscopic surgery yielded comparable results to conventional laparoscopic surgery in terms of blood loss, conversion to open surgery rate, intraoperative complication rate, postoperative complication rate, readmission rate, and wound infection rate for most surgical procedures. While the hospitalization costs of robot-assisted laparoscopic surgery were higher and the operative times of robot-assisted laparoscopic surgery were longer than conventional laparoscopic surgery, robot-assisted laparoscopic surgery reduced the length of hospital stay of patients in nearly all cases. Conclusion: Robot-assisted laparoscopic surgery achieved comparable results with conventional laparoscopic surgery for cholecystectomy, colectomy, hysterectomy, nephrectomy, and prostatectomy based on ten clinical outcomes.

Background: Developmental dysplasia of the hip (DDH) is a common disorder of atypical hip development. Pelvic osteotomy (e.g., according to Salter, Pemberton or Dega) may be indicated for children with DDH at walking age. The most popular postoperative treatment is a hip spica cast. Alternative postoperative options include abduction braces and non-weightbearing protocols combined with physical therapy. The aim of this systematic review was to determine the most effective form of postoperative treatment after unilateral pelvic osteotomy in children with DDH in terms of clinical and radiological outcomes and complications. Methods: A systematic review was conducted and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis 2020 guidelines and registered in the international prospective register of systematic reviews. Articles were selected from PubMed, Embase and Cochrane databases. The quality of all (non-)randomized included studies was assessed using the Methodological Index for Non-Randomized Studies (MINORS) criteria. Results: The search strategy yielded 3524 articles. Fourteen articles with 367 total hips were included in this review. A total of 312 hips were treated with spica casts, 49 with abduction braces and 6 with non-weightbearing protocols. The quality of evidence was moderate (MINORS, 3–12 points). All types of postoperative treatments had good clinical outcomes overall, without secondary displacement of the osteotomy. Clinical outcomes for spica casts were reported according to McKay’s criteria in 135 hips, with 123 excellent and 12 good results. Clinical outcomes for abduction braces showed satisfaction for all parents (49 of 49). The radiological outcome was overall well preserved with any postoperative treatment. There was a higher complication rate with the use of hip spica casts, including avascular necrosis, pain complaints and superficial infections. Conclusion: This systematic review showed no benefit of postoperative spica casts compared with abduction braces and avoidance of weightbearing after simple pelvic osteotomy for residual DDH.

Objectives: The deep submucosal migration of ingested foreign bodies into the pharyngolaryngeal mucosa is a sporadic event, and its management can be very challenging. In the case of the failure of endoscopic retrieval, open surgical techniques are usually required, and intraoperative ultrasonography can become a useful adjunct for identifying their precise localization. Methods: An 84-year-old woman presented with new-onset dysphagia and odynophagia after the accidental ingestion of a fragment of a toothpick a few hours before in the absence of hoarseness or respiratory distress. Ultrasonography and an unenhanced CT scan of the neck revealed a 3 cm linear foreign body embedded into the neck between the left pyriform sinus and the esophageal wall. Results: We report the removal of a fragment of a wooden toothpick deeply lodged between the left pyriform sinus and the esophageal wall, which was managed via an open transcervical approach with the aid of intraoperative ultrasound guidance. Conclusions: We suggest that both preoperative and intraoperative ultrasonography should represent the first-line imaging technique for deeply embedded neck foreign bodies. Full article

The main advantage of Oblique Lumbar Interbody Fusion (OLIF) is its ability to provide safe access to the lumbar spine while being a robust interbody fusion technique through a minimally invasive approach. This study reviews the postoperative complications of OLIF, offering a comprehensive understanding of its advantages and disadvantages. A total of 27 studies with 1275 patients were shortlisted based on our selection criteria. Complications were categorized into intra-operative, immediate post-operative, and delayed post-operative and were interpreted based on surgical procedure into stand-alone OLIF, OLIF with posterior stabilisation, and unspecified. Major complications exhibited a pooled prevalence of just 1.7%, whereas the overall pooled prevalence of complications was 24.7%. Among the subgroups, the stand-alone subgroup had the lowest prevalence of complications (14.6%) compared to the unspecified subgroup (29.6%) and the OLIF L2-5 with posterior stabilisation subgroup (25.8%). Similarly, for major complications, the stand-alone subgroup had the lowest prevalence (1.4%), while the OLIF L2-5 with posterior stabilisation subgroup (1.8%) and the unspecified OLIF L2-5 subgroup (1.6%) had higher rates. However, the differences were not statistically significant. In conclusion, the rate of major complications after OLIF is minimal, making it a safe procedure with significant benefits outweighing the risks. The advantages of OLIF L2-5 with posterior stabilisation over stand-alone OLIF L2-5 is a subject of discussion. Full article

Introduction: Hemivertebrae are a common defect of vertebral formation, potentially resulting in debilitating congenital scoliosis and necessitating highly traumatic surgery. Virtual surgical planning (VSP) and 3D-printed patient-specific implants (PSIs) have increasingly been applied to complex spinal surgery, and offer a range of potential benefits. Research Question: We report the use of 3D-printed PSIs and VSP as part of a two-level anterior lumbar interbody fusion (ALIF) for the management of lateral hemivertebra and congenital scoliosis. Material and Methods: A 53-year-old male with chronic low-back pain, due to L4 hemivertebra and mild congenital scoliosis, presented with new-onset leg pain. CT revealed L4/5 and L5/S1 degeneration and foraminal stenosis. Given the complex anatomy and extensive multi-level osteophytosis, 3D-printed PSIs were designed, manufactured, and implanted as part of a two-level ALIF. Results: Excellent implant fit was achieved intraoperatively, confirmed via postoperative imaging. VSP assisted with navigating challenging bony and vascular anatomy. Three-month postoperative imaging demonstrated construct stability, early signs of bony fusion, with implant placement, spinal curvature, and disc height corrections closely matching the VSP. Clinically, the patient’s pain and functional impairment had effectively resolved by nine-month follow up, as demonstrated through subjective and objective measures. Discussion and Conclusions: Virtual surgical planning and 3D-printed PSIs can be useful surgical aids in the management of the often-complex cases involving hemivertebrae and congenital scoliosis. This case of congenital pathology adds to the growing reports of PSI application to a variety of complex spinal pathologies, with analyses showing a close match of the postoperative construct to the preoperative VSP.

The main concern in anterior exposure of the lumbosacral spine is the risk of vascular injury during mobilization and retraction of the blood vessels. Preoperative planning is considered essential to reducing the incidence of vascular injury, although no consensus has been reached on the preferred methodology for such planning. This is a retrospective study, including all patients operated on by a single surgeon, who received anterior lumbar-spine surgery in the supine position as a primary procedure before undergoing an anterior lumbar interbody fusion (ALIF) or an artificial disc replacement (ADR). The aim of this study was to list the intraoperative complications observed. We included 156 patients (87 women; mean age, 48 years) who met the inclusion criteria. The overall complication rate was 6.4% (10/156). The most frequent complications were an incidental peritoneal opening (seven patients, 4.4%); two left–iliac-vein injuries (1.28%) that were sutured; and one dural tear during a decompression maneuver of the canal. No neurological, arterial, or ureteral injury or retrograde ejaculation was reported. The use of a sound protocol that includes planning, assessment of approach difficulty, and step-by-step surgical technique can reduce the rate of vascular injury in anterior lumbosacral-spine surgery.

Backgrounds: Liver surgery has developed progressively during the last 10 years, especially in minimally invasive approaches. Robotic surgery seemed to overcome laparoscopic limitations with 3D visualization, the increased degrees of freedom given with Endowrist instruments, tremor filtering, better dexterity, and improved ergonomics for the surgeon. Methods: This work was a retrospective analysis of our first 100 robotic hepatectomies from March 2020 to July 2022. Patient demographics characteristics and intra- and postoperative outcomes were analyzed. Results: A total of 59 males and 41 females, with a median age of 68 years, underwent a robotic liver resection. The indications for robotic liver resections were malignant lesions in 86% of patients. Anatomical resection (AR) was undertaken in 27% of cases and non-anatomical resection (NAR) in 63% of cases. None of the patients were converted to the ‘open’ approach. Postoperative complications were as follows: 1% of biliary leakage, 5% of ascites, 6% of pulmonary infections, and 3% of other sites’ infections. CONCLUSIONS Our results showed the satisfactory experience of a tertiary HPB center with its first 100 robotic liver resections. The opportunity to make the robotic approach routinary provided global growth of a surgical team, improving the quality of patient outcomes. Full article

Amniotic Band Syndrome (ABS) is a complex condition characterized by constricting rings and tissue synechiae, resulting in tissue necrosis and congenital anomalies. In newborns and infants with ABS, tissue necrosis can be profound, requiring a tissue defect reconstruction, realized by a Keystone Perforator Island Flap (KF). Primarily used for reconstruction after skin cancer excisions, KF’s applications expanded to defects of various etiologies and disorders throughout the body. Subsequently, additional KF types adapted to the particular tissue defects were developed. The KF’s preparation is relatively simple to perform leading to shorter operative times, and the postoperative monitoring is less laborious. Individualized surgical approaches and timing are essential for addressing the varied manifestations of ABS, with immediate treatment recommended for vascular compression, all-layered tissue necrosis, and nerve compression cases. To our knowledge, there is no published case in which a KF was used for the reconstruction of tissue defects and release of constriction rings in the context of an amniotic band syndrome. Therefore, the purpose of this article is to introduce the established surgical technique of KFs as an innovative surgical approach with satisfying reconstructive results for tissue defects and constriction ring release in ABS.

Anesthetic management for pregnant patients suffering from airway pathology poses unique challenges. The presence of a bilateral vocal cord granuloma adds further complexity to anesthetic management as it can potentially cause a compromised airway and respiratory distress. This case presents a pregnant patient with a bilateral vocal cord granuloma who underwent anesthesia using high-flow nasal cannula (HFNC) oxygenation and oxygen reserve index (ORi) monitoring. A 33-year-old pregnant woman, who underwent intubation six months ago, experienced hoarseness and was ultimately diagnosed with a bilateral granuloma. Due to the significant airway obstruction, neither intubation nor ventilation was feasible, thereby requiring a surgical intervention. Before the surgical removal, the patient’s oxygenation was ensured using HFNC oxygenation. After confirming the sufficient oxygenation of the patient with an ORi of 0.38, the operation commenced, and as it lasted approximately 3 min, the patient was able to tolerate the brief period without additional oxygen supply. Post-surgical excision, mask bagging, and HFNC oxygenation was resumed, driving the ORi to 0.39; then, the operation was resumed. Throughout the procedure, the SpO2 remained above 98. The combination of HFNC and ORi ensured adequate oxygenation and allowed for the early detection of hypoxemia during the procedure. This approach may be a good option for managing granulomas.

Objectives: This study was designed to determine objective surgical indications of correcting caudal end deviation of the nasal septum. Methods: We employed quantitative computed tomographic (CT) analysis and assessed the validity by comparing this with anterior rhinoscopic findings (AR findings). The study population consisted of 300 patients. The archived CT data were transferred to a workstation, and 3D CT volume-rendered images were generated using computer graphics tools. In the plane of the nostril entrance, we calculated ratios of the cross-sectional area of the convex side (narrower side) and the concave side (wider side), which is abbreviated as the N/W ratio. We also examined the presence of laterality between the right and the left cross-sectional area of the nasal valve based on the AR findings. Surgical procedures for whether to expose the caudal end were planned based on the AR findings and the N/W ratio. Results: A significant correlation was found between the AR findings and the N/W ratio. After surgery, the average N/W ratio improved from 0.53 ± 0.15 to 0.81 ± 0.15, and the average values of VAS scaling for nasal obstruction improved from 8.1 ± 0.2 to 1.0 ± 0.1. Conclusions: The quantitative CT analysis proposed in the study is a useful modality to objectively determine the surgical indications of managing the caudal end of the nasal septum. Full article

Purpose: Although open reduction and internal fixation (ORIF) by plating are the treatment of choice for diaphyseal fractures of the forearm, delayed union and non-union remain as existing complications. This study aimed to analyze predictive factors for the union time in diaphyseal fractures of the forearm. Methods: A retrospective study was conducted on all adult patients with diaphyseal forearm fractures who underwent surgical treatment with plate fixation between 2007 and 2016 at a tertiary care referral center. The patients were divided into two groups based on their union times: ≤3 months or >3 months. They were then compared for demographics, fracture pattern and characteristics, associated injuries, type of fixation, and quality of postoperative reduction. Results: Eighty-six diaphyseal forearm bone fractures (radius, ulna, or both) were observed in 55 adults. Out of these fractures, 55 (65.1%) achieved union within ≤3 months, 26 (30.3%) took more than 3 months to achieve union, and 4 (4.6%) resulted in nonunion. The use of a locking plate in open reduction and internal fixation of diaphyseal forearm fractures significantly increased the likelihood of union within ≤3 months (p = 0.043). The parameter of gap width at the fracture site, as observed on postoperative X-rays, showed a qualitative and quantitative correlation with union time (p = 0.028). Conclusion: The use of a locking plate, combined with reducing the gap width at the fracture site after reduction during open reduction and internal fixation (ORIF) of diaphyseal forearm fractures, is significantly correlated with an increased likelihood of achieving bone union within 3 months.

Since its inception in the early 1970s, bariatric surgery has experienced remarkable advancements, leading to improved patient outcomes. However, amidst these developments, the once-popular ileojejunal bypass procedure has faded into obscurity, along with its associated risks and complications. In this particular case, we present the medical history of a 68-year-old male who endured prolonged hospitalization due to a myriad of health issues, including malnutrition, kidney stones, chronic kidney disease, and persistent diarrhea following an ileojejunal bypass performed back in 1973. Troublingly, his symptoms were erroneously attributed to other causes for an extended period, overlooking the potential long-term effects of his prior surgery. This case emphasizes the importance of recognizing and monitoring the lasting impacts of historical surgical interventions, as well as the need for heightened vigilance in postoperative care.

Introduction: Achalasia is a pathology with an incidence of 1 in 100,000 inhabitants per year. There are very limited data on achalasia in the obese population, especially in those undergoing bariatric surgery. The approach of choice for cases of achalasia is the procedure partial fundoplication to correct the reflux; however, lacking a fundus due to a previous gastrectomy, an alternative that offers optimal results should be chosen. Here, we present the surgical approach in a case of esophageal achalasia and a history of vertical sleeve gastrectomy, where we performed a simultaneous Heller’s cardiomyotomy and laparoscopic Roux-en-Y gastric bypass, as well as the results obtained. Case Presentation: A 44-year-old woman with no chronic degenerative diseases, who had a vertical sleeve gastrectomy carried out 5 years ago. Her first symptoms manifested 17 months before, and they were dysphagia to liquids and then to solids, in addition to weight loss of 10 kg in 4 months. Her body mass index before the vertical sleeve gastrectomy was 32 kg/m2; her body mass index at the time of admission was 20 kg/m2; she also presented regurgitation and generalized weakness. After analyzing the surgical options, it was decided to perform a Heller cardiomyotomy and a Roux-en-Y gastric bypass. Discussion and Conclusions: The procedure turned out to be safe and successful in treating achalasia symptomatology, in addition to completely resolving the reflux symptoms. Full article
