Background/Objective: Patients who have undergone Billroth II gastrectomy may develop gastroparesis, hypomotility, and reflux esophagitis. These patients are at risk of aspiration of gastric contents into the lungs when subsequently sedated for Endoscopic Retrograde Cholangiopancreatography (ERCP) procedures. The aim of this study was to compare conscious sedation and deep sedation in terms of pulmonary complications in this selected cohort. Methods: Patients who had previously undergone Billroth II surgery and underwent ERCP procedure with sedation for gallstones or biliary tract strictures in a tertiary hospital between January 2020 and September 2023 were studied. Patient records were retrospectively obtained from the hospital information system. All the patients were divided into two groups as conscious sedation (Group CS) and deep sedation (Group DS). The groups were compared statistically in terms of pulmonary complications. Results: A total of 63 ERCP procedures were performed on 28 patients who had undergone Billroth II gastrectomy. There were 37 procedures involving conscious sedation (Group CS) and 26 involving deep sedation (Group DS). No statistically significant difference was found regarding pulmonary aspiration (p = 0.297) and other respiratory complications such as laryngospasm or desaturation between the two groups. In Group DS, it was observed that vomiting incidence was higher (p = 0.012), and airway maneuver requirements were increased (p = 0.007). Conclusions: In patients who have undergone Billroth II gastrectomy, both conscious sedation and deep sedation techniques can be used effectively during ERCP procedures. The complication rates and patient outcomes of the two techniques are comparable. The occurrence of respiratory complications leading to adverse post-procedural outcomes requires careful monitoring and meticulous follow-up for these patients. Full article

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

Endoscopic management of benign pancreaticobiliary disorders encompasses a range of procedures designed to address complications in gallstone disease, choledocholithiasis, and pancreatic disorders. Acute cholecystitis is typically treated with cholecystectomy or percutaneous drainage (PT-GBD), but for high-risk or future surgical candidates, alternative decompression methods, such as endoscopic transpapillary gallbladder drainage (ETP-GBD), and endoscopic ultrasound (EUS)-guided gallbladder drainage (EUS-GBD), are effective. PT-GBD is associated with significant discomfort as well as variable adverse event rates. EUS-GBD leverages lumen-apposing metal stents (LAMS) for direct access to the gallbladder, providing the ability to treat an inflamed GB internally. Choledocholithiasis is primarily managed with ERCP, utilizing techniques to include balloon extraction, mechanical lithotripsy, or advanced methods such as electrohydraulic or laser lithotripsy in cases of complex stones. Altered anatomy from bariatric procedures like Roux-en-Y gastric bypass may necessitate specialized approaches, including balloon-assisted ERCP or EUS-directed transgastric ERCP (EDGE). Post-operative complications, including bile leaks and strictures, are managed endoscopically using sphincterotomy and stenting. Post-liver transplant anastomotic and non-anastomotic strictures often require repeated stent placements or advanced techniques like magnetic compression anastomosis in refractory cases. In chronic pancreatitis (CP), endoscopic approaches aim to relieve pain and address structural complications like pancreatic duct (PD) strictures and calculi. ERCP with sphincterotomy and stenting, along with extracorporeal shock wave lithotripsy (ESWL), achieves effective ductal clearance for PD stones. When traditional approaches are insufficient, direct visualization with peroral pancreatoscopy-assisted lithotripsy is utilized. EUS-guided interventions, such as cystgastrostomy, pancreaticogastrostomy, and celiac plexus blockade, offer alternative therapeutic options for pain management and drainage of peripancreatic fluid collections. EUS plays a diagnostic and therapeutic role in CP, with procedures tailored for high-risk patients or those with complex anatomy. As techniques evolve, endoscopic management provides minimally invasive alternatives for patients with complex benign pancreaticobiliary conditions, offering high clinical success and fewer complications.

Background and aims: Despite technical advances, endoscopic retrograde cholangiopancreatography (ERCP) is associated with complications and potentially lethal outcomes. Sarcopenia, a complex syndrome mainly associated with aging, has been recognized as a predictor of poor surgical outcomes. Thus far, the impact of sarcopenia on ERCP remains unknown. The present study evaluates the role of sarcopenia as a predictor of ERCP-related outcomes in a cohort of elderly patients. Methods: Patients who underwent ERCP between June 2019 and January 2023 were retrospectively included. Demographic and procedure-associated data were collected. Sarcopenia was assessed using the skeletal muscle index (SMI) measured from a single axial slice through the L3 vertebra on a CT scan. ERCP-related outcomes were recorded. Univariate and multivariate analyses were used to assess the correlation between sarcopenia and procedural outcomes. Results: In total, 256 patients were enrolled, of whom 30 (11.7%) were sarcopenic. Cardiopulmonary complications of ERCP occurred in 3.5%. Sarcopenia was associated with higher 30-day and 12-month post-ERCP mortality (OR 3.45, p = 0.03; OR 3.87, p = 0.004) and longer hospitalization time (7 vs. 11 days, p = 0.003). Conclusions: SMI is an easy and objective index of sarcopenia that could be used to predict ERCP outcomes. Indeed, sarcopenia was independently associated with prolonged hospitalization and increased mortality in a retrospective cohort of elderly patients. Full article

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is a key therapeutic procedure in diseases of the pancreas or bile ducts. The understanding and effective management of the risks associated with the procedure, especially in the context of possible infectious complications, is crucial for patients’ safety. The aim of this review was to analyze the results of studies on antibiotic prophylaxis for infectious complications of ERCP, pancreatoscopy, and cholangioscopy. Methods: This study is a review of the articles available in PubMed, Medline, and Embase published in the last 30 years. Results: Nineteen studies and six sets of guidelines on antibiotic prophylaxis before ERCP were retrieved. Conclusions: Based on the available studies and recommendations, it can be concluded that antibiotic prophylaxis before ERCP is beneficial for immunocompromised patients or those at risk of bacterial endocarditis. In other groups of patients, antibiotic prophylaxis reduces the risk post-ERCP bacteremia but does not significantly reduce the risk of cholangitis and infectious complications. The effectiveness of antibiotic prophylaxis in patients at risk of incomplete biliary drainage needs to be verified in further studies. Full article

Objectives: Risk factors for post-endoscopic retrograde cholangiopancreatography (ERCP) complications have been extensively studied and are well established; most complications are mild and self-limiting. This study aims to identify patients at risk of severe early post-ERCP complications. Methods: We conducted a retrospective cohort study with data from 2810 ERCP procedures performed at Ghent University Hospital between 2016 and 2022. Patient records and a maintained ERCP registry were used to identify all ERCP-related complications and possible risk factors. The AGREE classification was used to determine the severity of the complication. Univariate and multivariate logistic regression analyses were performed to identify independent predictors of severe complications. Results: Out of 2810 procedures, 223 cases (7.9%) had post-ERCP complications, with severe complications occurring in 20.3% of cases. The most common severe complication was haemorrhage (22/49 severe complications, 44.9%), with perforation having the highest probability of being severe (10/15 cases, 67%). Independent predictors of severe complications included anticoagulative therapy (OR 6.3, 95% CI 1.4–28.3, p = 0.016) and high procedural difficulty (Schutz category 3: OR 11.5, 95% CI 2.4–54.6, p = 0.002; category 4: OR 5.9, 95% CI 1.4–23.5, p = 0.012). Conclusions: Patients on anticoagulation and those undergoing complex ERCP procedures (Schutz 3 or 4) are at particular risk of severe procedure-related complications. 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

This study aims to provide valuable references for clinicians in selecting appropriate surgical methods for biliary tract stones based on patient conditions. In this paper, the advantages and disadvantages of various minimally invasive cholelithiasis surgical techniques are systematically summarized and innovative surgical approaches and intelligent stone removal technologies are introduced. The goal is to evaluate and predict future research priorities and development trends in the field of gallstone surgery. In recent years, the incidence of gallstone-related diseases, including cholecystolithiasis and choledocholithiasis, has significantly increased. This surge in cases has prompted the development of several innovative methods for gallstone extraction, with minimally invasive procedures gaining the most popularity. Among these techniques, PTCS, ERCP, and LCBDE have garnered considerable attention, leading to new surgical techniques; however, it must be acknowledged that each surgical method has its unique indications and potential complications. The primary challenge for clinicians is selecting a surgical approach that minimizes patient trauma while reducing the incidence of complications such as pancreatitis and gallbladder cancer and preventing the recurrence of gallstones. The integration of artificial intelligence with stone extraction surgeries offers new opportunities to address this issue. Regarding the need for preoperative preparation for PTCS surgery, we recommend a combined approach of PTBD and PTOBF. For ERCP-based stone extraction, we recommend a small incision of the Oddi sphincter followed by 30 s of balloon dilation as the optimal procedure. If conditions permit, a biliary stent can be placed post-extraction. For the surgical approach of LCBDE, we recommend the transduodenal (TD) approach. Artificial intelligence is involved throughout the entire process of gallstone detection, treatment, and prognosis, and more AI-integrated medical technologies are expected to be applied in the future.

Background: Liver transplant recipients often require endoscopic retrograde cholangiopancreatography (ERCP) for biliary complications, which can lead to infections. This retrospective single-center study aimed to identify risk factors for infectious complications following ERCP in liver transplant patients. Methods: A retrospective analysis was conducted on 285 elective ERCP interventions performed in 88 liver transplant patients at a tertiary care center. The primary endpoint was the occurrence of an infection following ERCP. Univariable and multivariable regression analyses, Cox regression, and log-rank tests were employed to assess the influence of various factors on the incidence of infectious complications. Results: Among the 285 ERCP interventions, isolated anastomotic stenosis was found in 175 cases, ischemic type biliary lesion (ITBL) in 103 cases, and choledocholithiasis in seven cases. Bile duct interventions were performed in 96.9% of all ERCPs. Infections after ERCP occurred in 46 cases (16.1%). Independent risk factors for infection included male sex (OR 24.19), prednisolone therapy (OR 4.5), ITBL (OR 4.51), sphincterotomy (OR 2.44), cholangioscopy (OR 3.22), dilatation therapy of the bile ducts (OR 9.48), and delayed prophylactic antibiotic therapy (>1 h after ERCP) (OR 2.93). Additionally, infections following previous ERCP interventions were associated with an increased incidence of infections following future ERCP interventions (p < 0.0001). Conclusion: In liver transplant patients undergoing ERCP, male sex, prednisolone therapy, and complex bile duct interventions independently raised infection risks. Delayed antibiotic treatment further increased this risk. Patients with ITBL were notably susceptible due to incomplete drainage. Additionally, a history of post-ERCP infections signaled higher future risks, necessitating close monitoring and timely antibiotic prophylaxis. Full article

Introduction: Gallstone disease (GSD) is among the most common disorders worldwide. Gallstones are established in up to 15% of the general population. Laparoscopic cholecystectomy (LC) has become the “gold standard” for treatment of GSD but is associated with a higher rate of certain complications, namely, bile duct injury (BDI). Biliary fistulas (BF) are a common presentation of BDI (44.1% of all patients); however, they are mainly external. Post-cholecystectomy internal BF are exceedingly rare. Case report: a 33-year Caucasian female was admitted with suspected BDI after LC. Strasberg type E4 BDI was established on endoscopic retrograde cholangiopancreatography (ERCP). Urgent laparotomy established biliary peritonitis. Delayed surgical reconstruction was planned and temporary external biliary drains were positioned in the right and left hepatic ducts. During follow-up, displacement of the drains occurred with subsequent evacuation of bile through the external fistula, which resolved spontaneously, without clinical and biochemical evidence of biliary obstruction or cholangitis. ERCP established bilio-duodenal fistula between the left hepatic duct (LHD) and duodenum, with a stricture at the level of the LHD. Endoscopic management was chosen with staged dilation and stenting of the fistulous tract over 18 months until fistula maturation and stricture resolution. One year after stent extraction, the patient remains symptom free. Discussion: Management of post-cholecystectomy BDI is challenging. The optimal approach is determined by the level and extent of ductal lesion defined according to different classifications (Strasberg, Bismuth, Hannover). Type E BDI are managed mainly surgically with a delayed surgical approach generally deemed preferable. Only three cases of choledocho-duodenal fistulas following LC BDI currently exist in the literature. Management is controversial, with expectant approach, surgical treatment (biliary reconstruction), or liver transplantation being described. Endoscopic treatment has not been described; however, in the current paper, it proved to be successful. More reports or larger case series are needed to confirm its applicability and effectiveness, especially in the long term. Full article
