Background: The aim was to explore patients’ reflections related to their choice of participating or not in a multimodal prehabilitation randomised controlled trial (RCT) in relation to minor surgery. Methods: A qualitative study with 22 semi-structured in-depth interviews on patients awaiting ventral hernia repair was conducted between March and May 2024 and reported according to the COREQ guideline. All were eligible to participate in a prehabilitation RCT; twelve had accepted, and ten had declined. The interviews were analysed using Kirsti Malterud’s method of systematic text condensation, resulting in themes. Results: Five global themes were identified: “time commitment”, “research participation for the general good”, “personal benefits of RCT participation”, “ambivalence of own health and lifestyle”, and “complications after surgery”. All participants found the RCT and its prehabilitation programme a positive initiative. Those who had accepted to participate in the RCT emphasised personal benefits and contributing to research, while those who had declined expressed more ambivalence regarding lifestyle change, the extent of personal advantage, and prioritising of time. Conclusions: Those who declined RCT participation generally had more elaborate and ambivalent reflections than those who had accepted. Addressing ambivalence regarding lifestyle change, personal benefits, and prioritising time might be a relevant focus point for increasing inclusion rates in prehabilitation RCTs and in clinical practice to increase patients’ readiness for lifestyle change.

Background/Objectives: Ventral hernia repair has evolved with the introduction of minimally invasive techniques like l-IPOM and rTA-RM. While robotic surgery offers advantages in precision and ergonomics, its higher costs pose questions regarding its cost-effectiveness compared to laparoscopic approaches. Methods: A retrospective analysis of patients with primary or incisional ventral hernias undergoing either l-IPOM or rTA-RM between February 2022 and October 2023 was conducted. Data on demographics, surgical outcomes, hospital costs, disposable supplies, and robotic system expenses were collected. A one-to-one propensity score matching (PSM) was used to ensure comparability between the groups. Results: After matching, 30 patients were included in each group. The rTA-RM group had longer operative times (93.2 vs. 74.4 min, p = 0.004) but shorter hospital stays (1 day vs. 2 days, p = 0.003) and lower postoperative pain scores (median VAS score 3 vs. 5, p = 0.004). Total costs were comparable between rTA-RM and l-IPOM (EUR 6862 vs. EUR 6575, p = 0.32), with robotic surgery incurring higher capital costs but lower disposable supply costs (EUR 1057 vs. EUR 2006, p < 0.01). Conclusions: Despite the higher per-case cost associated with robotic systems, overall costs for rTA-RM were similar to those for l-IPOM, suggesting that robotic surgery may be cost-competitive due to lower disposable supply expenses and shorter hospital stays. Further research is needed to assess long-term outcomes and broader economic impacts. Full article

Objectives: The objective of this study was to assess the tissue response and strength of traditional and unidirectional suture materials, depending on the conditions of use and the timing following implantation. Methods: Eighty male Wistar rats were randomly assigned to four groups depending on the suture used: unidirectional absorbable V-loc^TM 180 or non-absorbable V-loc^TM PBT and traditional absorbable Maxon^TM or non-absorbable Novafil^TM. Three and six weeks following the closure of the abdominal wall defect (AWD) and subcutaneous suture implantation at the withers according to group assignment, 10 animals from each group were euthanized for implanted sutures mechanical testing and histological examination. Results: The inflammatory reaction in the AWD closure area was maximal and significantly different from the subcutaneous implantation by week 3 for all groups. At six weeks, the tissue reaction did not depend on the place of implantation. However, four rats from the Maxon^TM group demonstrated suture failure with diastasis formation. Non-absorbable barbed sutures exhibited an absence of suture failure and the maximum scar thickness. Both intact absorbable materials (V-Loc^TM 180 and Maxon^TM) exhibited a significant breaking strength margin over the non-absorbable. By week 6, the preserved strength of the V-loc^TM 180 sutures at the AWD was 33% (15–58%), and under the skin—49.7% (48–59%) (p = 0.005). For Maxon^TM, these values were 38% (35–48%) for the AWD and 44% (34–49%) for the subcutaneous implantation. Conclusions: Absorbable and non-absorbable suture materials, depending on the conditions and timing of implantation, cause various tissue reactions which could affect the wound healing and the number of postoperative complications.

Background: Ventral hernias are common abdominal wall defects requiring surgical repair to prevent complications. This study compared two techniques: minimally invasive enhanced-view totally extraperitoneal (eTEP) approach and the open sublay (OS) method, historically regarded as the gold standard. Methods: A retrospective single-center study was conducted between July 2019 and March 2023 at the Department for General and Visceral Surgery, Klinikum Oldenburg. All patients who underwent either eTEP or OS for ventral hernia repair were included. Patient demographics and perioperative data were collected and compared. Results: A total of 139 patients were analyzed, with 92 undergoing eTEP repair and 47 undergoing OS. Both groups were comparable in demographic and clinical characteristics. Significant differences were found in defect size (median 6 cm² for eTEP vs. 16 cm² for OS, p < 0.028) and mesh size (median 450 cm² for eTEP vs. 150 cm² for OS p < 0.001). Operative time (p = 0.119) and postoperative pain levels over 3 days showed no significant differences (VAS Day1 p = 0.884; VAS Day3 p = 0.636). Intraoperative complications were 2.17% for eTEP and 6.38% for OS (p = 0.207). Postoperative complications (6.52% vs. 21.28%, p = 0.009) and hospital stay (median 3 days vs. 5 days, p < 0.001) were significantly lower in the eTEP group. Conclusions: eTEP is a safe, effective procedure and appears to offer more advantages than OS for ventral hernia repair. It is associated with a significantly lower complication rate, as well as shorter hospital stay. Full article

Background and Objectives: Incisional hernias are a common and costly complication of surgery, occurring in up to 20% of midline incisions within 3 years of initial operation. Risk factors for incisional hernia include incision site, fascial closure technique, body mass index (BMI), surgical site infections, and gastrointestinal surgery. Limited studies have compared procedural type as a risk factor for hernia formation. The goal of this study was to examine incisional hernia rates among general surgical and gynecologic procedures. Materials and Methods: We queried our Research Data Warehouse for inpatients who had undergone common open abdominal surgeries between January 2012 and December 2022. Patients’ index operations were identified based upon Current Procedural Terminology (CPT) codes and presence of a postoperative incisional hernia was determined by occurrence of an incisional hernia ICD10 diagnosis code more than 2 weeks postoperatively. The main study outcome was time to incisional hernia diagnosis. Results: A total of 4447 patients were identified. Postoperatively, 241 (5.4%) patients were diagnosed with incisional hernias. Hernia rates at 1, 3 and 5 years were 3% (SE 0.003), 6% (0.004) and 8% (0.005), respectively. Patients undergoing exploratory laparotomy (hazard ratio 3.9, p < 0.001), bowel resection (HR 5.5, p < 0.001), and primary hernia repair (HR 13.0, p < 0.001) were found to have significantly increased risk for incisional hernia development compared to those undergoing hysterectomy, following adjustment for comorbid risks, age, sex, and BMI. Conclusions: Exploratory laparotomy, bowel resection, and primary ventral hernia repair are associated with a higher incidence of incisional hernia relative to gynecologic procedures. This relatively unstudied comparison warrants further investigation. Full article

Objectives: Incisional ventral hernia repair remains a challenging surgery for abdominal wall surgeons. We report the results at 48 months post-surgery regarding open ventral hernia repair (OVHR), analyzing the recurrence rate and incidence of chronic pain. Methods: This was a retrospective, observational study of 111 consecutive patients who underwent OVHR. Between January 2017 and December 2019, patient data were collected from a database and classified by hernia type. Through questionnaires and clinical examinations, the recurrence rate and incidence of chronic pain (measured using the VAS score and a Likert scale) were obtained. Results: In all patients, the hernia repair was performed via an open approach. Long-term follow-up (48 months after surgery) revealed that 20% of patients experienced mild chronic pain alongside the flanks, and the recurrence rate was 5%. Moreover, long-term follow-up revealed the following secondary outcomes: movement limitations in sports were reported in 7% of patients, and movement limitations during long walking were reported in 11% of patients. Conclusions: Our technique for OVHR is a safe procedure with a low rate of recurrence and chronic pain. Our future aim is to organize a prospective study. Full article

Background/Objectives: Ventral hernia repair (VHR) is a common surgical intervention linked to specific surgical site complications. In such occurrences, the related morbidity is often substantial. Although known risk factors have long been recognized, their systematic inclusion in risk stratification systems lacks universal validation. This study evaluates the effectiveness and correspondence of three risk assessment tools—CeDAR, VHWG, and the modified VHWG—in predicting postoperative wound complications in VHR patients. Methods: We analyzed data from 203 patients who underwent VHR for incisional midline or lateral wall hernia across two surgical departments between 2019 and 2023. Each patient was scored using CeDAR, VHWG, and the modified VHWG systems. Outcomes were assessed based on surgical site occurrences (SSOs) such as seroma formation, wound infections, and recurrences. Results: The incidence of SSOs was 8.9%, with two recorded deaths (0.89%). CeDAR scores showed a statistically significant relationship with SSOs but failed to accurately predict complication rates across subgroups. The VHWG grading system effectively predicted higher complication rates for grades III and IV compared to grades I and II, though its modified version did not show significant predictive improvements. Secondary outcomes indicated a higher SSO rate in patients requiring posterior component separation (TAR) and those with larger hernia defects, though the differences were not statistically significant. Major preoperative risk factors, including smoking, diabetes, and obesity, did not show significant correlations with SSO rates in this study. Conclusions: Current risk estimation tools inadequately predict SSOs in VHR. Enhancing prediction accuracy will require incorporating both patient-specific and surgical factors, potentially through advanced algorithms and large-scale studies. Full article

Background and Objectives: Surgical site infections (SSIs) are a significant complication following ventral hernia repair, potentially leading to prolonged hospital stays and increased morbidity. This study aimed to evaluate whether closed incision negative pressure wound therapy (ciNPWT) reduces the incidence of SSI after ventral hernia repair with polypropylene mesh compared to standard wound care. Materials and Methods: A randomized study was conducted with 100 patients undergoing ventral hernia repair using a polypropylene mesh. Participants were divided into two groups: a control group ($n=50$), which received standard sterile gauze dressing with an iodine-based disinfectant, and an intervention group ($n=50$), treated with the ciNPWT system (Vivano^® by HARTMANN) for 5 days postoperatively. The primary outcome was the incidence of SSI within one year after surgery. Secondary outcomes included the influence of factors such as age, sex, smoking status, and hernia size on SSI occurrence. The study was approved by the Ethics Committee at the University Hospital Ostrava, adhering to the ethical standards of the Helsinki Declaration. Results: The incidence of SSI was lower in the ciNPWT group compared to the standard care group (4% vs. 12%), though this difference did not reach statistical significance. No significant effect of sex or smoking status on SSI was observed. The control group had a shorter mean length of hospital stay. Larger hernias in the non-ciNPWT group were more prone to SSIs, as expected. Conclusions: Although limited by a small sample size, the findings suggest that ciNPWT may be associated with a reduced rate of SSI following ventral hernia repair. Further studies with larger populations are needed to confirm these results. Full article

Background and Objectives: Ventral hernias (VH) pose significant challenges for surgeons due to the risk of recurrence, complexities in aligning abdominal muscles, and selecting the most suitable layer for mesh augmentation. This study aims to evaluate the effectiveness of utilizing the anterior rectus fascia as a turnover flap in conjunction with onlay mesh reinforcement, a procedure known as the modified Chevrel technique (MCT). Materials and Methods: We conducted a retrospective analysis of patients who were operated on using MCT for abdominal hernias between January 2013 and December 2019. Data were extracted from our hospital’s electronic database. Recurrence rates, as well as the rates of surgical site occurrences (SSO), surgical site infections (SSI), and surgical site occurrences requiring procedural intervention (SSOPI), were analyzed based on patients’ comorbidities and demographic characteristics. Results: The median follow-up period was 42.9 months (range: 14–96), and the recurrence rate was 4% (n = 3). Among the recurrent cases, three patients had chronic obstructive pulmonary disease, representing a statistically significant association (p = 0.02). Although all patients with recurrence were obese, this association did not reach statistical significance (p > 0.05). The mean hospitalization duration was 17.6 days (range: 6–29). SSO, SSI, and SSOPI rates were 39 (52%), 12 (16%), and 32 (42%), respectively. Conclusions: Managing VH remains a surgical challenge, emphasizing the importance of achieving effective abdominal closure for both functional and cosmetic outcomes. MCT presents a relatively simple approach compared to techniques like transversus abdominis release (TAR) and anterior component separation (ACS), with acceptable rates of SSO, SSOPI, SSI, and recurrence.

Background/Objectives: The success of peritoneal dialysis is highly dependent on the integrity of the abdominal wall. Therefore, routine examination and treatment of abdominal hernias can prevent peritoneal dialysis (PD) failure, discontinuation, and conversion to hemodialysis. In this present study, we present our examination protocol for patients proposed for PD and our attitude in treating parietal defects in patients on peritoneal dialysis. Objectives: highlight whether PD is a risk factor for the occurrence of ventral hernias, the relationship between associated pathologies and the occurrence of hernias and the need for an HD switch in the postoperative period. Methods: Between January 2016 and December 2022, a group of 133 patients proposed for insertion of a PD catheter were evaluated according to the protocol established by our hospital. Routine examination for the diagnosis of abdominal hernias and repair before starting the DP is part of the procedure. We included patients with a 3 year minimum follow-up after insertion and evaluated the incidence of parietal defects that appeared during PD treatment. Results: Nine patients were diagnosed and operated on for abdominal hernia before starting peritoneal dialysis and none of them had a recurrence of hernia during PD. Twelve patients were diagnosed with abdominal hernias during dialysis treatment (9% incidence) and the median length of time at which parietal defects occur during PD is 12.5 months [range 2–48]. Median BMI is 27.12 [range 22.3–31.24], with a female–male ratio of 2:1 Five patients were transferred to HD, three permanently and two patients temporarily. No patient abandoned PD treatment due to the presence of an abdominal parietal defect. Conclusions: Diagnosis of ventral hernias prior to the time of catheterization for PD leads to a decrease in the incidence of parietal defects during PD and is mandatory in patients who are candidates for PD. Open alloplastic surgical procedures are safe procedures with a low recurrence rate in PD patients. The postoperative continuation of PD is feasible but the decision is to be made by the multidisciplinary team and individualized for each patient. Full article

Introduction: The versatile open modular design of the newly introduced robotic platform Hugo^TM RAS is expected to allow its rapid spread in general surgery. However, the system is not yet approved for use in oesophageal and HPB-surgery and is not licensed worldwide. The aim of this work was to review the current spectrum of general surgical procedures that may be feasibly and safely performed with Hugo. Methods: We retrospectively reviewed our own series and performed a systematic review of all the published reports of general surgical procedures performed with this system in the literature. Results: Seventy patients underwent general surgery with Hugo at our institution, and another 99 patients were reported in the literature. The most common procedures were colorectal (n = 55); cholecystectomy (n = 44); repair of groin, ventral and hiatal hernias (n = 34); upper GI (n = 28); adrenalectomy (n = 6); and spleen cyst deroofing (n = 2). No device-related complications were reported. Arm collisions and technical problems were rare. The docking and console times improved in all series. The port positions and robotic arm configurations varied among authors and depended on the surgical indication, patient characteristics and surgeon’s preference. Conclusions: A wide spectrum of general surgical procedures has been safely and effectively performed with the Hugo RAS, even by robotically inexperienced teams with a limited choice of instruments. Technical improvements to the system and the introduction of robotic energy devices may help Hugo evolve to a vital alternative to established robotic systems. Full article

The global prevalence of obesity continues to rise, contributing to an increased frequency of abdominal wall reconstruction procedures, particularly ventral hernia repairs, in individuals with elevated body mass indexes. Undertaking these operations in obese patients poses inherent challenges. This review focuses on the current literature in this area, with special attention to the impact of concomitant panniculectomy. Obese individuals undergoing abdominal wall reconstruction face elevated rates of wound healing complications and hernia recurrence. The inclusion of concurrent panniculectomy heightens the risk of surgical site occurrences but does not significantly influence hernia recurrence rates. While this combined approach can be executed in obese patients, caution is warranted, due to the higher risk of complications. Physicians should carefully balance and communicate the potential risks, especially regarding the increased likelihood of wound healing complications. Acknowledging these factors is crucial in shared decision making and ensuring optimal patient outcomes in the context of abdominal wall reconstruction and related procedures in the obese population.

Problems related to ventral hernia repairs (VHR) are very common, and evaluating them using computational methods can assist in selecting the most appropriate treatment. This study is based upon data from 3339 patients from different European countries observed during the last 12 years (2012–2023), which were collected by specialists in hernia surgery. Most patients underwent standard surgical procedures, with a growing trend towards laparoscopic surgery. This paper focuses on statistically evaluating the treatment methods in relation to patient age, body mass index (BMI), and the type of repair. Appropriate mathematical methods are employed to extract and classify the selected features, with emphasis on computational and machine-learning techniques. The paper presents surgical hernia treatment statistics related to patient age, BMI, and repair methods. The main conclusions point to mean groin hernia repair (GHR) complications of 19% for patients in the database. The accuracy of separating GHR mesh surgery with and without postoperative complications reached 74.4% using a two-layer neural network classification. Robotic surgeries represent 22.9% of all the evaluated hernia repairs. The proposed methodology suggests both an interdisciplinary approach and the utilization of computational intelligence in hernia surgery, potentially applicable in a clinical setting. Full article

The management of giant inguinoscrotal hernias remains a challenge as a result of the loss of the intra-abdominal domain from long-standing hernia contents within the scrotum. Multiple techniques have been described for abdominal wall relaxation and augmentation to allow the safe return of viscera from the scrotum to the intraperitoneal cavity without adversely affecting cardiorespiratory physiology. Preoperative progressive pneumoperitoneum, phrenectomy, and component separation are but a few common techniques previously described as adjuncts to the management of these massively large hernias. However, these strategies require an additional invasive stage, and reproducibility remains challenging. Botulinum toxin A (BTA) has been successfully used for the management of complex ventral hernias. Its use for these hernias has shown reproducibility and a low side effect profile. In the present report, we describe our institutional experience with BTA for giant inguinal hernias in two patients and present a review of the literature. In one case, a 77-year-old man with a substantial cardiac history presented with a giant left inguinal hernia that was interfering with his activities of daily living. He had BTA six weeks prior to inguinal hernia repair. Repair was performed via an inguinal incision with a favorable return of the viscera into the peritoneum. He was discharged on the same day of the operation. A second patient, 78 years of age, had a giant right inguinoscrotal hernia. He had a significant cardiac history and was treated with BTA six weeks prior to inguinal hernia repair via a groin incision. Neither patient had complaints nor recurrence at 7- and 3-month follow-ups. While the literature on this topic is scarce, we found 13 cases of inguinal hernias treated with BTA as an adjunct. BTA might be a promising adjunct for the management of giant inguinoscrotal hernias in addition to or in place of current strategies. Full article
