Background: Post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) remains the most frequent and clinically significant complication of ERCP, with a multifactorial etiology involving patient- and procedure-related risk factors. Despite preventive measures such as NSAIDs and peri-procedural stenting, the incidence of PEP has not substantially declined. We aimed to assess clinical determinants of PEP in a large real-world cohort treated with standardized procedural protocols. Materials and Methods: This retrospective single-center study analyzed 806 patients who underwent ERCP between January 2019 and December 2021. All procedures were performed by a single operator under general anesthesia with standardized prophylaxis (diclofenac 100 mg per rectum and cefazolin 2 g intravenously). Patients with delayed ERCP (>48 h from admission) or active acute pancreatitis were excluded. Logistic regression was used to identify independent predictors of PEP, hospital stay, and in-hospital mortality. Results: PEP occurred in 60 patients (7.4%). Independent risk factors included stenosis of the papilla of Vater (OR = 2.45; p = 0.025), gallbladder stones (OR = 2.66; p = 0.001), prior acute pancreatitis (OR = 2.72; p = 0.005), and sphincterotomy (OR = 2.53; p = 0.016). PEP was associated with longer hospitalization (MD = 4.5 days; p < 0.001) and increased in-hospital mortality (6.7% vs. 1.7%; p = 0.032). Conclusion: Stenosis of the papilla, gallbladder stones, prior acute pancreatitis, and sphincterotomy independently increased the risk of PEP, whereas older age, previous ERCP, and pancreaticoduodenal tumors were associated with a reduced risk. Despite standardized prophylaxis, PEP remains a relevant clinical concern. Identification of high-risk patients and individualized procedural planning are essential to minimizing complications.

Background: Pancreatic stents (PSs) play a crucial role in the management of pancreatic duct obstructions, particularly in the context of endoscopic retrograde cholangiopancreatography (ERCP). However, stent migration remains a significant complication, leading to risks such as pancreatitis, pancreatic duct stenosis, and abscess formation. This study aims to evaluate the efficacy of various endoscopic techniques for retrieving proximally migrated or broken pancreatic stents, highlighting optimal strategies for improving patient outcomes. Methods: A retrospective multicenter review was conducted across six hospitals from 2016 to 2024. Patients with proximally migrated or broken pancreatic stents referred for endoscopic retrieval after failed attempts at other facilities were included. Demographic data, stent characteristics, and retrieval techniques were analyzed. Endoscopic methods included SpyGlass forceps, SpyGlass baskets, Soehendra retriever stents, balloon sweeps, flower baskets, and extension pancreatic sphincterotomy. Procedural success, retrieval times, and post-procedural outcomes were assessed. Results: Twelve patients underwent endoscopic retrieval, including two with broken stents. All procedures were successful, with retrieval times averaging 30 to 45 min. Two patients developed pancreatic duct narrowing, requiring balloon dilation. All patients had new stents placed to maintain duct patency, and no major complications were observed. Follow-up evaluations confirmed complete resolution of migration-related issues, with all stents removed. Conclusions: Endoscopic retrieval of migrated pancreatic stents is highly effective, with specialized techniques ensuring a 100% success rate in this study. Early intervention and the selection of appropriate retrieval methods are critical in minimizing complications. Further research is needed to refine retrieval strategies and standardize protocols to enhance clinical outcomes. Full article

Background/Objectives: The management of refractory pancreatic duct (PD) and cystic duct leaks may represent an endoscopic challenge. Standard endoscopic therapy involves pancreatic/biliary sphincterotomy and stenting during endoscopic retrograde cholangiopancreatography (ERCP). After conservative (fasting, parenteral nutrition, and use of somatostatin analogs) or conventional endoscopic treatments fail, a surgical approach is usually required, leading to higher mortality due to several technical complications. Previous evidence of the endoscopic use of N-butyl-2-cyanoacylate (NBCA) for treating pancreaticobiliary leaks is reported, although the evidence is scarce. Methods: Six patients with pancreaticobiliary leaks (three IT pancreatic leaks and three Class A sec. Strasberg post-cholecystectomy biliary leaks) refractory to previous treatment were treated with the endoscopic topical application of NBCA. All our patients gave informed consent. The procedures were all performed between December 2017 and February 2025 at a tertiary referral center for biliopancreatic endoscopy. Results: Therapeutic success, as shown both endoscopically and radiologically, was 100%, and no procedural complication was reported. In one patient with biliary leak, standard cannulation of the cystic duct stump with the guidewire was unsuccessful, requiring a peroral cholangioscopy (SpyGlass System DSII) to directly visualize the leakage site, allowing a precise closure of the wall defect with NBCA. Conclusions: NBCA injection could represent a safe and effective endoscopic option in refractory PD of the tail of the pancreas and cystic duct leaks. Larger and further studies are necessary to confirm these results. Full article

Artificial Intelligence (AI) is transforming pancreaticobiliary endoscopy by enhancing diagnostic accuracy, procedural efficiency, and clinical outcomes. This narrative review explores AI’s applications in endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP), emphasizing its potential to address diagnostic and therapeutic challenges in pancreaticobiliary diseases. In EUS, AI improves pancreatic mass differentiation, malignancy prediction, and landmark recognition, demonstrating high diagnostic accuracy and outperforming traditional guidelines. In ERCP, AI facilitates precise biliary stricture identification, optimizes procedural techniques, and supports decision-making through real-time data integration, improving ampulla recognition and predicting cannulation difficulty. Additionally, predictive analytics help mitigate complications like post-ERCP pancreatitis. The future of AI in pancreaticobiliary endoscopy lies in multimodal data fusion, integrating imaging, genomic, and molecular data to enable personalized medicine. However, challenges such as data quality, external validation, clinician training, and ethical concerns—like data privacy and algorithmic bias—must be addressed to ensure safe implementation. By overcoming these challenges, AI has the potential to redefine pancreaticobiliary healthcare, improving diagnostic accuracy, therapeutic outcomes, and personalized care. Full article

Background/Objectives: Pancreatitis is the most frequent and serious complication of endoscopic retrograde cholangiopancreatography (ERCP), with an incidence between 2 and 10% and a mortality rate of 1 in 500 patients. Etiopathogenesis remains poorly understood. The aim of this study was to analyze the incidence of post-ERCP pancreatitis (PEP) and to identify potential patient- and procedure-related risk factors (RF) in a cohort of patients from a tertiary referral center in Romania. Methods: We conducted a retrospective, observational, single-center study in which we analyzed ERCP procedures performed in the Gastroenterology Department of Colentina Clinical Hospital, Bucharest, Romania, between January 2019 and September 2024. All patients received intrarectal diclofenac before the ERCP and were hydrated with at least 1500 mL of Ringer’s solution after the procedure in the absence of contraindications, according to the latest international recommendations. Results: In total, 2743 ERCPs were performed in the given time period, while 2350 procedures were analyzed in the study. PEP occurred in 350 cases (14.9%). Of these, 191 (54.6%) occurred in males with a mean age of 66.5 years. Procedural RF with adjusted odds ratios (OR) were as follows: difficult cannulation of the common bile duct, OR = 3.734, p < 0.001, main pancreatic duct catheterization, OR = 1.454, p = 0.022, and endoscopic papillary balloon dilatation, with an OR of 3.258, p < 0.001. Pancreatic duct stent placement was shown to prevent PEP in this study group (p < 0.001). Conclusions: PEP remains a serious complication of ERCP, associated with significant morbidity and occasional mortality. While some proven risk factors, such as age, gender, or comorbidities, are unmodifiable, avoiding Wirsung duct cannulation and pancreatography, or prophylactic pancreatic duct stent placement, could play a significant role in PEP prevention.

Acute pancreatitis is an inflammatory condition of the exocrine pancreas that is a common indication for hospital admission and has had an increasing incidence in the last few decades. The diagnosis of acute pancreatitis requires the satisfaction of two out of three criteria: (1) abdominal pain radiating to the back, (2) serum lipase or amylase levels three or more times the upper limit of the normal level, and (3) findings indicating pancreatitis obtained via a computed tomography (CT) scan or magnetic resonance imaging (MRI). The different etiologies include gallstones, autoimmune disorders, alcohol abuse, smoking, hypertriglyceridemia, obesity, drugs, and post-endoscope retrograde cholangiopancreatography (ERCP). The initial investigation includes serum amylase and lipase analysis, a lipid panel including triglycerides, analysis of immunoglobulins, a full blood count, electrolyte analysis, a hemoglobin A1c test, a complete metabolic panel, and transabdominal ultrasound. The initial therapy includes oxygen supplementation, the provision of intravenous fluids, pain control, and a nutrition regime. Early oral feeding is encouraged if tolerated; if not, liquid supplement provision or enteral tube feeding within 48 h of admission has shown better outcomes. Some complications of acute pancreatitis are necrosis, infection, insulin resistance leading to diabetes mellitus, and pancreatic exocrine insufficiency requiring enzyme supplementation. Patients need to attend regular follow-ups and abstain from alcohol and smoking (if warranted) to prevent the recurrence of acute pancreatitis. The mortality rate of acute pancreatitis has decreased in the past few decades because of better management skills, but the recent rise in acute pancreatitis episodes is concerning. Sustained endeavors through clinical trials are required to establish a broad variety of drugs that can be used for acute pancreatitis episodes. Full article

Background: Peroral cholangioscopy (POCS) is valuable for assessing malignant biliary strictures; however, biliary drainage prior to POCS often hinders accurate diagnosis. Objectives: This retrospective study aimed to investigate the feasibility of POCS using a newly developed cholangioscope, CHF-B290, during initial endoscopic retrograde cholangiopancreatography (ERCP) for malignant biliary strictures. Methods: This multicenter retrospective study included patients who underwent initial ERCP for malignant biliary strictures at two institutions between January 2018 and March 2022. Patients who underwent initial ERCP with POCS were classified into the POCS group, and those without POCS were classified into the non-POCS group. To prevent post-POCS cholangitis, the original irrigation system for CHF-B290 was used in all POCS examinations. The primary endpoint was the rate of post-ERCP biliary infections, and the secondary endpoints were other ERCP-related complications, including pancreatitis, bleeding, and perforation. Results: Overall, 53 and 94 patients were included in the POCS and non-POCS groups, respectively. For the primary endpoint, the rate of post-ERCP biliary infection was not significantly different between the two groups (1.9% vs. 5.3%, p = 0.42). For the secondary endpoints, no significant differences were observed in the rates of post-ERCP pancreatitis (5.7% vs. 6.4%, p = 1.00) and other ERCP-related complications. The overall complication rate was 9.4% in the POCS group and 13% in the non-POCS group (p = 0.60). Conclusions: POCS during the initial ERCP for malignant biliary strictures is feasible.

Objectives: To evaluate the role of ERCP (endoscopic retrograde cholangio-pancreatography) and EUS (endoscopic ultrasound) and to describe the efficacy and safety of these procedures in a paediatric cohort with chronic pancreatitis (CP) and acute recurrent pancreatitis (ARP). Methods: All patients (<18 years) undergoing an ERCP or EUS for ARP and CP between January 2008 and December 2022 were included. Data collection included indications for the procedure, technical success, adverse events and outcome data. Results: A total of 222 ERCPs were performed in 98 patients with CP and ARP (60% female, median age 10 years). The commonest indications were a main pancreatic duct stricture (PD) with or without a stone within the main PD. Successful cannulation was achieved in 98% of cases. Improved stricture resolution was demonstrated in 63% of patients. The overall adverse event rate for ERCP was low (n = 8/222, 3.6%). An improvement in abdominal pain was demonstrated in (75/98) 76% of patients. Their Body Mass Index also significantly improved post ERCP (15.5 ± 1.41 vs. 12.9 ± 1.16 kg/m², p = 0.001). A total of 54 EUS procedures were undertaken in 48 individuals. Moreover, 35 individuals underwent a therapeutic EUS procedure, for which the commonest indication was the drainage of a pancreatic fluid collection. The overall complication rate was low (n = 2.4%) in all EUS cases. Conclusions: ERCP and EUS can be safely and effectively used in a paediatric population with indications analogous to an adult cohort. Full article

Background and Aim: Endoscopic retrograde cholangiopancreatography (ERCP) is a valuable procedure for pancreatobiliary disorders but carries significant risks, including post-ERCP pancreatitis (PEP). The exact cause of PEP is unclear, but mechanical and thermal injuries during the procedure and patient-related factors have been implicated. This study aims to investigate the possible contribution of potential pancreatotoxic drug (PPD) exposure to PEP risk. Methods: This was a retrospective, single-centre, cohort study conducted at Canberra Hospital, a tertiary university hospital. Consecutive ERCP performed with native papillae within a 4-year period from January 2019 to January 2023 were evaluated. Details of ERCP procedures, patient characteristics, and all medications were contemporaneously collected. All patients had follow-up phone calls or review within 24 h post procedure. The diagnosis of PEP was based on the Cotton consensus definition. Results: A total of 32 out of 444 patients (7.2%) developed PEP. There was no significant difference in the incidence of PEP between patients taking PPD compared to patients who were not (7.1% vs. 7.6%, p = 0.845). Three factors were independently associated with PEP in the multivariate analysis: the presence of a periampullary diverticulum (OR = 5.4, 95% CI 1.7–15.3, p = 0.002), the performance of pre-cut sphincterotomy (OR = 2.8, 95% CI 1.2–6.4, p = 0.017), and pancreatic duct cannulation (OR = 3, CI 1.3–7, p = 0.01). Conclusions: The overall incidence of pancreatitis in our selected group of ERCP patients with native papillae was 7.2%. Our study did not find the use of PPD to be a statistically significant risk factor for PEP. Full article

The prognostic factors associated with severe-to-fatal post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) remain unclear despite the extensive number of studies on PEP. In total, 3739 ERCP patients with biliary disease with an intact papilla and indicated for ERCP were prospectively enrolled at 36 centers from April 2017 to March 2018. Those with acute pancreatitis diagnosed before ERCP, altered gastrointestinal anatomy, and an American Society of Anesthesiologists (ASA) physical status > 4 were excluded. Univariate and multivariate logistic regression analyses were performed on patient-related factors, operator-related factors, procedure-related factors, and preventive measures to identify potential prognostic factors for severe-to-fatal PEP. Multivariate analyses revealed pancreatic guidewire-assisted biliary cannulation (OR 13.59, 95% CI 4.21–43.83, p < 0.001), post-ERCP non-steroidal anti-inflammatory drug (NSAID) administration (OR 11.54, 95% CI 3.83–34.81, p < 0.001), and previous pancreatitis (OR 6.94, 95% CI 1.45–33.33, p = 0.015) as significant risk factors for severe-to-fatal PEP. Preventive measures included endoscopic biliary sphincterotomy (EST; OR 0.29, 95% CI, 0.11–0.79, p = 0.015) and prophylactic pancreatic stents (PPSs; OR 0.11, 95% CI, 0.01–0.87, p = 0.036). In biliary ERCP, pancreatic guidewire-assisted biliary cannulation, NSAID administration after ERCP, and previous pancreatitis were risk factors for severe-to-fatal PEP, whereas EST and PPS were significant preventive measures for severe-to-fatal PEP.

Background: Despite numerous advances that have aimed to increase the safety of endoscopic retrograde cholangiopancreatography (ERCP), post-ERCP pancreatitis (PEP) still remains a major issue. We aimed to assess the rate of PEP as well as the relation to the cannulation techniques in our unit, a high-volume center in north-eastern Romania. Methods: ERCPs performed in our unit from March to August 2022 were retrospectively included. Data concerning demographic information, presence of difficult cannulation, the technique used for cannulation, as well as immediate complications, were gathered from the electronic database. Results: 233 ERCPs were included. PEP was diagnosed in 23 (9.9%) of cases. Precut sphincterotomy (PS), transpancreatic sphincterotomy (TPBS), and a combination of TPBS and PS were performed in 6.4%, 10.3%, and 1.7% of cases, respectively, while an Erlangen precut papillotomy was performed in one case. Both in patients with PS and TPBS the rate of PEP was 20%. When the two techniques were associated, the rate of PEP was 25%. TPBS and PS represented risk factors for PEP (OR 1.211 for a CI of 0.946–1.551, p = 0.041, and OR 1.124 for a CI of 0.928–1.361, p = 0.088, respectively). No PEP-associated deaths were found. Conclusions: Both PS and TPBS presented a similar risk of PEP. Full article

Background: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) has shown constant incidence throughout time, despite advances in endoscopic technology, devices, or personal skills of the operating endoscopists, with prevention and prediction of severity in PEP being constant concerns. Several prospective studies have investigated the role of systemic inflammatory response syndrome (SIRS) criteria or the quick Sequential Organ Failure Assessment (qSOFA) score in the PEP severity assessment. However, there are no clearly defined tools for the prediction of PEP severity. Methods: A total of 403 patients were prospectively monitored 60 days after ERCP for the detection of PEP development. Consequently, we evaluated the lengths of stay, incidence of organic dysfunction, and mortality rates of these patients. The predictive power of the univariate model was evaluated by using the receiver operating characteristic curve and analyzing the area under the curve (AUC). Results: Incidence of PEP was similar to that reported in the majority of trials. The 60-day survival rate of PEP patients reached 82.8%. A qSOFA score ≥ 1 is a very good predictor for organ dysfunction (AUC 0.993, p < 0.0001). SIRS can also be considered a significant predictor for organic dysfunctions in PEP patients (AUC 0.926, p < 0.0001). However, only qSOFA was found to significantly predict mortality in PEP patients (AUC 0.885, p = 0.003), with SIRS criteria showing a much lower predictive power. Neither SIRS nor qSOFA showed any predictive value for the length of stay of PEP patients. Conclusion: Our study offers novel information about severity prediction in PEP patients. Both SIRS criteria and qSOFA showed good predictive value for organic dysfunction, mortality, and hospitalization. Full article

Pathological examination by endoscopic ultrasound–fine needle aspiration is not possible in approximately 10% of pancreatic tumor cases. Pancreatic juice cytology (PJC) is considered an alternative diagnostic method. However, its diagnostic capability is insufficient, and PJC has been repeatedly redevised. Serial pancreatic juice aspiration cytological examination (SPACE) and secretin-loaded PJC (S-PJC) have been recently introduced as alternative diagnostic methods. This study aimed to determine the diagnostic capacity and safety of SPACE and S-PJC using a propensity score-matched analysis. The sensitivity, specificity, and accuracy were 75.0%, 100%, and 92.3% for S-PJC, respectively, and 71.4%, 100%, and 92.3% for SPACE, respectively, meaning that there was no significant difference between the groups. Four patients (15.4%) each in the S-PJC and SPACE groups experienced complications, including postendoscopic retrograde cholangiopancreatography, pancreatitis, and cholangitis. Overall, there was no difference in efficacy and safety between the SPACE and S-PJC groups. Full article

Introduction: Wire-guided cannulation (WGC) during endoscopic retrograde cholangiopancreatography (ERCP) is a selective biliary cannulation technique aimed at improving the successful selective biliary cannulation rate and reducing the rate of post-ERCP pancreatitis (PEP) incidence. This study aimed to evaluate the effectiveness of angled-tip guidewires (AGW) vs. straight-tip guidewires (SGW) for biliary cannulation via WGC by a trainee. Methods: We conducted a prospective, single-center, open-labeled, randomized, and controlled trial. Fifty-seven patients were enrolled in this study and assigned randomly to two groups (Group A to S and Group S to A). In this study, we started selective biliary cannulation via WGC with an AGW or an SGW for 7 min. If cannulation was unsuccessful, the other guidewire was used, and cannulation was continued for another 7 min (cross-over method). Results: The selective biliary cannulation success rate over 14 min was significantly higher with an AGW compared with an SGW over 14 min (57.8% vs. 34.3%, p = 0.04) and for the second 7-min segment (36.4% vs. 0%, p = 0.04). No significant difference was found for adverse events such as pancreatitis between the two guidewires. Conclusions: Our results suggest that an AGW is recommended for WGC performed by a trainee.

Background: Despite post-ERCP pancreatitis (PEP) being a major focus of outcomes research in endoscopic retrograde cholangiopancreatography (ERCP), little is known regarding the frequency with which asymptomatic biochemical and/or radiologic pancreatic alterations occur in patients following ERCP. Methods: Adult inpatients undergoing ERCP were identified from a prospective ERCP registry. Patients with any abdominal pain, confirmed PEP, or pancreatitis or abnormal pancreatic enzymes preceding ERCP were excluded. Primary outcomes were asymptomatic lipase elevation on bloodwork within 24 h of ERCP or asymptomatic cross-sectional imaging findings consistent with acute pancreatitis in the absence of clinical PEP within 14 days. Multinomial logistic regression and multiple logistic regression were used to examine associations between exposures and lipase levels and between PEP or imaging findings, respectively. Results: In total, 646 and 187 patients were analyzed as part of the biochemical and radiologic cohorts, respectively. A total of 26.0% of patients had asymptomatic elevations in lipase above the upper limit of normal (ULN) within 24 h, and 9.4% had elevations >3× ULN. A total of 20.9% of patients had incidental findings of enlargement, inflammation/edema/fat stranding, peri-pancreatic fluid collections, and/or necrosis on cross-sectional imaging within 14 days. Pancreatic contrast injection was associated with higher odds of asymptomatic lipasemia (adjusted odds ratio, AOR, 7.22; 95% confidence intervals, CI, 1.13 to 46.02), as was the use of the double-wire technique (AOR 15.74; 95% 1.15 to 214.74) and placement of a common bile duct stent (AOR 4.19; 95% CI 1.37 to 12.77). Over 10 cannulation attempts were associated with the presence of one or more radiologic finding(s) (AOR 33.95; 95% CI 1.64, to 704.13). Conclusions: Significant rates of incidental biochemical and/or radiologic pancreatic abnormalities are present following ERCP. Clinicians should be aware of our findings to minimize misclassification and better direct healthcare utilization. Full article
