Abstract
INTRODUCTION AND AIM Endoscopic retrograde cholangiopancreatography (ERCP) is a complex procedure. Clinical guidelines assess competence in ERCP through a defined number of procedures, but multiple factors are involved. Our aim was to analyze the morphology of the papilla of Vater as an independent factor in selective common bile duct cannulation during resident training. MATERIAL AND METHODS Patients that underwent ERCP were studied consecutively. All ERCPs were begun by a resident in training. The type of papilla was classified according to Haraldsson, including those with previous sphincterotomy. Cannulation difficulty and success and their relation to the type of papilla were documented. The analysis was divided into three 4-month periods. RESULTS Of the 429 patients, cannulation was difficult in 101 (23.5%). The residents achieved selective cannulation of the common bile duct in 276 (64.3%) and the cannulation success rate at the end of their training was 81.7%. Cannulation was performed with the least difficulty in papillae with previous sphincterotomy (2.8%), unlike the type 4 papilla, which was difficult to cannulate in 50% of the cases. The lowest overall cannulation success was in the type 2 papilla (81.8%). CONCLUSION Papilla type can influence cannulation success, but it is not the only related factor. Patients that underwent previous sphincterotomy appear to be the cases in whom ERCP training can be started.

Abstract
AIMS Training programs are essential to introduce new methods for bile duct clearance. Visual examination via cholangioscopy is ideal to diagnose and treat biliary tract diseases such as cancer and choledocholithiasis. However, surgeons rarely use cholangioscopes. Specific training is required to master laparoscopic and percutaneous cholangioscopy. This study aims to assess skill acquisition and retention during cholangioscopy training in the Image-Guided Therapies Masterclass. METHODS This prospective study enrolled 17 physicians undergoing training in interventional treatments of biliary diseases. A novel disposable cholangioscope and access kit were used with a biliary tract model including two simulated common bile duct (CBD) stones. The curriculum required visualization of all critical structures before removal of one stone with a Dormia basket. After informed consent, demographic data and time to exercise completion were recorded on each of two subsequent training days. Task-specific questions were measured at the completion of training using a Likert scale (strongly disagree to strongly agree, 1-5 points). RESULTS All participants successfully completed the task (6F/11 M, age 36 ± 5 years; 13 surgeons, 4 interventional radiologists; median experience with percutaneous procedures 2 years, range 0-20). Significant improvement in mean task completion time was observed (day 1: 172 ± 59 s, day 2: 89 ± 45 s; P < 0.0001). All task-specific questions were answered with a median rating of 5/5: "The platform facilitates cholangioscopy" and "This training method accelerates gain in proficiency and is useful for residents/fellows" (IQR 5-5), "This platform is useful to measure the proficiency level" and "There is an application for simulation in percutaneous surgery training" (IQR 4.5-5), "The platform is user-friendly" and "The model quality recreates realistic scenarios" (IQR 4-5). CONCLUSION Cholangioscopic bile duct exploration and stone retrieval were achieved by all participants using a dedicated training program and physical simulator. Significant skill progress was observed during 2 days of dedicated training.

Abstract
Background and study aim Simulator-based training has been extensively studied in training gastroduodenoscopy and colonoscopy and shown to significantly improve learning curves of novices. Data on simulator-based training in endoscopic retrograde cholangiopancreatography (ERCP) are scarce. We aimed to determine the impact of 2-day intensive hands-on simulator training on the course of the learning curve of novice trainees. Methods We conducted a prospective cohort study using a validated mechanical ERCP simulator (Boškoski-Costamagna ERCP Trainer). Six trainees were allocated to the simulation course program (SG). Each of these trainees were paired with an endoscopy trainee starting regular ERCP training at the same center who had no exposure to a simulation course program (control group; CG). The course included lectures, live ERCP demonstrations, and hands-on ERCP training to educate trainees in basic techniques related to cannulation, stent placement, stone extraction and stricture management. After the course, both the SG and CG started formal ERCP training in their respective centers. The Rotterdam Assessment Form for ERCP was used to register each performed ERCP. Simple moving average was applied to create learning curves based on successful common bile duct (CBD) cannulation. Outcomes were plotted against a historical cohort (HC). Results Thirteen trainees were included, six trainees in the SG and seven trainees in the CG, with a total of 717 ERCPs. Mean successful ERCP cannulation rate was higher for the simulator group at baseline compared to both CG and HC, 64% versus 43% and 42%, respectively. Differences became less explicit after 40 ERCPs, but persisted until a median of 75 ERCPs. Conclusions We demonstrate that 2-day hands-on simulator-based ERCP training course has a positive effect on the learning curves of ERCP trainees and should be considered an integral part of the training curricula for ERCP to develop skills prior to patient-based training.

Incidence and Cross-Continents Differences in Endoscopic Retrograde Cholangiopancreatography Outcomes Among Patients With Cirrhosis: A Systematic Review and Meta-Analysis. Gastroenterology Res 2023; 16:105-117. [PMID: 37187552 PMCID: PMC10181340 DOI: 10.14740/gr1610] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Accepted: 03/28/2023] [Indexed: 05/17/2023] Open
Abstract
Background There are conflicting data on the frequency and variability of endoscopic retrograde cholangiopancreatography (ERCP) outcomes in patients with cirrhosis. Our aim was to systematically review the literature on the incidence of post-ERCP adverse events in cirrhotic patients and to examine the differences across continents. Methods We searched PubMed/MEDLINE, EMBASE, Scopus, and Cochrane databases to identify studies reporting adverse events after ERCP in patients with cirrhosis from conception to September 30, 2022. The random effects model was used to calculate odds ratios (ORs), mean differences (MDs), and confidence intervals (CIs). A P value < 0.05 was considered statistically significant. Heterogeneity was assessed using the Cochrane Q-statistic (I2). Results Twenty-one studies that included 2,576 cirrhotic patients and 3,729 individual ERCPs were analyzed. The pooled overall rate of adverse events after ERCP in patients with cirrhosis was 16.98% (95% CI: 13.06-21.29%, P < 0.001, I2 = 86.55%). ERCPs performed in Asia had the highest ERCP adverse events with an overall complication rate of 19.90%, while the lowest overall adverse events were in North America at 13.04%. The pooled post-ERCP bleeding, pancreatitis, cholangitis and perforation were 5.10% (95% CI: 3.33-7.19%, P < 0.001, I2 = 76.79%), 3.21% (95% CI: 2.20-5.36%, P = 0.03, I2 = 42.25%), 3.02% (95% CI: 1.19-5.52%, P < 0.001, I2 = 87.11%), and 0.12% (95% CI: 0.00 - 0.45, P = 0.26, I2 = 15.76%), respectively. The pooled post-ERCP mortality rate was 0.22% (95% CI: 0.00-0.85%, P = 0.01, I2 = 51.86%). Conclusions This meta-analysis shows that the overall complication rates after ERCP, bleeding, pancreatitis, and cholangitis are high in patients with cirrhosis. Because cirrhotic patients are more likely to have post-ERCP complications, with significant cross-continent variations, the risks and benefits of ERCP in this patient population should be carefully considered.

Propensity score-matched analysis of physician-controlled wire-guided cannulation as an effective technique against difficult cannulation in endoscopic retrograde cholangiopancreatography: A retrospective study. PLoS One 2023; 18:e0285118. [PMID: 37115752 PMCID: PMC10146477 DOI: 10.1371/journal.pone.0285118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Accepted: 04/16/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND Advanced endoscopic retrograde cholangiopancreatography (ERCP) cannulation strategies for difficult cases could replace conventional techniques, in which assistants control guidewires. We aimed to compare the safety and efficacy of a new salvage cannulation strategy, physician-controlled wire-guided cannulation (PCWGC), with those of a conventional strategy. METHODS This retrospective study included patients with naïve papillae who underwent ERCP between January 2018 and December 2020. Patients, divided into two groups, received initial cannulation using a conventional catheter. After failed cannulation, the second attempt used PCWGC and double-guidewire technique (DGT) in the new and conventional strategy groups, respectively. Propensity score-matching (PSM) analysis compared outcomes between groups. Primary outcome included overall success rate, while secondary outcomes included cannulation time, adverse events, and cannulation difficulty subgroup analysis. RESULTS The new strategy group comprised 255 (47.6%) of 536 patients who underwent ERCP. The total cannulation success rate was 98.4% (vs. 97.2%, p = 0.318), with similar post-ERCP pancreatitis (PEP) (1.8% vs. 2.4%, p = 0.64) rates. Following 1:1 PSM, 219/438 patients were allocated to both the conventional and new strategy groups, and 46 patients from the difficult cannulation subgroup were distributed evenly among groups. No difference in overall cannulation success rate existed between the groups before (97.2% vs. 98.4%) and after PSM (96.8% vs. 98.2%). The primary cannulation success rate was higher in the conventional strategy group, while the secondary cannulation success rate was higher in the new strategy group. However, the difficult cannulation subgroup PSM results showed that only the salvage cannulation success rate was significant (9/23, 39.1% vs. 18/23, 78.3%, p = 0.007). In the difficult cannulation subgroup, the salvage cannulation success rate for PCWGC was four times higher than DGT (95% confidence interval; 1.129-14.175), with no significant difference in PEP rate (p = 0.571). CONCLUSIONS PCWGC demonstrated greater efficacy than the conventional salvage technique. PCWGC could be a safe and useful technique, especially for difficult biliary cannulation.

Abstract
BACKGROUND During ERCP for biliary indication, when a difficult bile duct (BD) cannulation occurs, with unintended access to the main pancreatic duct (PD), both double guidewire technique (DGW) and transpancreatic biliary sphincterotomy (TPBS) can be performed. We aimed to compare the technical success and adverse events (AEs) rate of these techniques. METHODS A retrospective analysis of patients with naïve papillae referred to the Pancreas Institute of Verona from January 2016 and July 2021 to undergo ERCP for biliary indications was performed. RESULTS Overall, 202 patients (53.5% males, mean age 67.2 years) were evaluated (96 DGW, 106 TPBS). Malignant biliary stricture was the most common ERCP indication (78.2%). The rate of success in deep biliary cannulation was significantly higher in the DGW group (94.8%) compared to TPBS (79.2%) at the first attempt (p = 0.001). This result was also confirmed in the subgroup of patients with malignant distal stricture (72/77, 93.5% vs 63/80, 78.8%, p = 0.01). No significant difference in AEs rate, particularly in PEP incidence was found between the two groups. CONCLUSIONS DGW demonstrated a higher success rate and similar safety profile compared with TPBS in difficult biliary cannulation. Based on this retrospective study, DGW should be preferred over TPBS in case of unintended PD cannulation. Further prospective studies are needed to confirm our results.

Abstract
Background and study aims Growing emphasis on quality and patient safety has supported the shift toward competency-based medical education for advanced endoscopy trainees (AETs). In this study, we aimed to examine Canadian AETs learning curves and achievement of competence using an ERCP assessment tool with strong evidence of validity. Methods This prospective study was conducted at five institutions across Canada from 2017-2018. Data on every fifth procedure performed by trainees were collected using the United Kingdom Joint Advisory Joint Advisory Group of Gastrointestinal Endoscopy (JAG) ERCP Direct Observation of Procedural Skills (DOPS) tool, which includes a four-point rating scale for 27 items. Cumulative sum (CUSUM) analysis was used to create learning curves for overall supervision ratings and ERCP DOPS items by plotting scores for procedures performed during training. Results Eleven trainees who were evaluated for 261 procedures comprised our sample. The median number of evaluations by site was 49 (Interquartile range (IQR) 31-76) and by trainee was 15 (IQR 11-45). The overall cannulation rate by trainees was 82 % (241/261), and the native papilla cannulation rate was 78 % (149/191). All trainees achieved competence in the "overall supervision" domain of the ERCP DOPS by the end of their fellowship. Trainees achieved competency in all individual domains, except for tissue sampling and sphincteroplasty. Conclusions Canadian AETs are graduating from fellowship programs with acceptable levels of competence for overall ERCP performance and for the most specific tasks. Learning curves may help identify areas of deficiency that may require supplementary training, such as tissue sampling.

Abstract
ABSTRACT Background This paper aims to determine factors associated with difficult biliary cannulation (DBC) that are identifiable before procedures. Methods This is a nested case-control study within a historical cohort in adult patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) from 2015-2019 in the Hospital Universitario San Ignacio, Colombia. This study assessed the associations among variables that could be identified before or at the beginning of procedures and the probability of DBC. These associations were evaluated through a bivariate and multivariate analysis. The study used criteria for DBC defined by the European Society of Gastrointestinal Endoscopy. Results A total of 498 ERCP performed in 376 patients were analyzed. Of all procedures, 144 (29%) fulfilled criteria for DBC. The multivariate analysis showed an association between DBC and the acute care hospital setting (OR:2.92; CI95% 1.70-5.01; P<0.001), redundant papilla (OR:7.26; CI95% 3.38-15.61; P<0.001), or peridiverticular papilla (OR:2.45; CI95% 1.38-4.36; P=0.002). No association was found between DBC and endoscopist’s experience, bilirubin levels, or dilation of the biliary tract. Conclusion The DBC is a frequent event. Alterations in the papilla and ERCP performed in the acute care hospital setting are the principal factors associated with DBC. This information might be useful to predict DBC and establish healthcare and administrative strategies to reduce its implications.

UK Joint Advisory Group consensus statements for training and certification in endoscopic retrograde cholangiopancreatography. Endosc Int Open 2022; 10:E37-E49. [PMID: 35047333 PMCID: PMC8759929 DOI: 10.1055/a-1629-7540] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Accepted: 08/24/2021] [Indexed: 12/25/2022] Open
Abstract
Background and study aims Despite the high-risk nature of endoscopic retrograde cholangiopancreatography (ERCP), a robust and standardized credentialing process to ensure competency before independent practice is lacking worldwide. On behalf of the Joint Advisory Group (JAG), we aimed to develop evidence-based recommendations to form the framework of ERCP training and certification in the UK. Methods Under the oversight of the JAG, a modified Delphi process was conducted with stakeholder representation from the British Society of Gastroenterology, Association of Upper Gastrointestinal Surgeons, trainees and trainers. Recommendations on ERCP training and certification were formulated after formal literature review and appraised using the GRADE tool. These were subjected to electronic voting to achieve consensus. Accepted statements were peer-reviewed by JAG and relevant Specialist Advisory Committees before incorporation into the ERCP certification pathway. Results In total, 27 recommendation statements were generated for the following domains: definition of competence (9 statements), acquisition of competence (8 statements), assessment of competence (6 statements) and post-certification support (4 statements). The consensus process led to the following criteria for ERCP certification: 1) performing ≥ 300 hands-on procedures; 2) attending a JAG-accredited ERCP skills course; 3) in modified Schutz 1-2 procedures: achieving native papilla cannulation rate ≥80%, complete bile duct clearance ≥ 70 %, successful stenting of distal biliary strictures ≥ 75 %, physically unassisted in ≥ 80 % of cases; 4) 30-day post-ERCP pancreatitis rates ≤5 %; and 5) satisfactory performance in formative and summative direct observation of procedural skills (DOPS) assessments. Conclusions JAG certification in ERCP has been developed following evidence-based consensus to quality assure training and to ultimately improve future standards of ERCP practice.

Accurate endoscopic identification of the afferent limb at the Y anastomosis using the fold disruption sign after gastric resection with Roux-en-Y reconstruction. Dig Endosc 2022; 34:238-243. [PMID: 34516705 DOI: 10.1111/den.14128] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 08/30/2021] [Accepted: 09/08/2021] [Indexed: 02/08/2023]
Abstract
In patients with Roux-en-Y (RY) reconstruction for gastric resection, the newly defined "fold disruption" (FD) sign can be useful to distinguish the afferent limb from the efferent limb at the Y anastomosis when balloon endoscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) is performed. The FD sign was defined as endoscopic findings of the internal folds disrupted toward the afferent limb and continued toward the efferent limb at the Y anastomosis. In this prospective observational study, the accuracy of the FD sign was evaluated for those who underwent BE-ERCP after gastric resection with RY reconstruction. Of 28 patients for whom the accuracy could be evaluated among 30 enrolled patients, the afferent limb was identified using the FD sign with 100% accuracy. For the other two patients, the scope could not reach the target lumen due to severe intestinal adhesion in one and reached the target lumen without recognition of the Y anastomosis in the other. There was no patient for whom the FD sign could not be judged for any reason, such as a blurred anastomosis line, unclear folds, sticky discharge and blood coating the surface, when the Y anastomosis was recognized. The FD sign was a highly accurate tool for distinguishing the afferent limb from the efferent limb in patients after gastric resection with RY reconstruction. This study was registered in UMIN (issued ID, UMIN000038326).

Abstract
Quality metrics and standardization has become critical as the Affordable Care Act mandates that the Center for Medicare and Medicaid Services change reimbursement from volume to a value-based system. While the most commonly used quality indicators are related to that of colonoscopy, quality metrics for other procedures and endoscopy units have been developed mainly by the American College of Gastroenterology and the American Society of Gastrointestinal Endoscopy. Data to show that these quality metrics, especially in the field of advanced endoscopy as well as in the era of COVID-19 pandemic, can improve patient outcomes, are anticipated.

Is Cholecystectomy a cause of difficult biliary cannulation in endoscopic retrograde cholangiopancreatography? Acta Gastroenterol Belg 2021; 84:563-569. [PMID: 34965037 DOI: 10.51821/84.4.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/21/2022]
Abstract
BACKGROUND AND STUDY AIM In European Society of Gastrointestinal Endoscopy guidelines, biliary cannulation of naive papillae is defined as difficult in the presence of more than 5 papilla contacts, more than 5min cannulation time or more than one unintended pancreatic duct cannulation or opacification. It is not known whether cholecystectomy is a cause of difficult biliary cannulation. This study aimed to investigate whether cholecystectomy (CCY) is a cause of difficult biliary cannulation in patients who have undergone Endoscopic Retrograde Cholangiopancreatography (ERCP) for choledocholithiasis. PATIENTS AND METHODS Adult patients with naive papillae and those who underwent ERCP for common bile duct stones and/or sludge were included in this retrospective study. Patient demographics, clinical presentation (acute cholangitis, biliary pancreatitis or biliary colic), periprocedural data including laboratory and radiological findings and ERCP results were compared between no-CCY and post-CCY groups. RESULTS 438 patients were included in the present study and 347 of these patients were in the no-CCY group and 91 patients were in post-CCY group. A statistically significant difference was found in the number of patients with difficult cannulation in the post-CCY group (n=30, 33.0%) patients compared to the no- CCY group (n=67, 19.3%) (p=0.011). According the multivariate analyses results, presence of history of cholecystectomy was found an independent risk factor of difficult cannulation (Odds ratio: 2.014; 95 % Cl 1.205-3.366; p=0.008). CONCLUSIONS The results showed that biliary cannulation was significantly more difficult in patients with cholecystectomy who underwent ERCP for common bile duct stones.

World J Clin Cases 2021; 9:4166-4177. [PMID: 34141779 PMCID: PMC8173434 DOI: 10.12998/wjcc.v9.i17.4166] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 04/05/2021] [Accepted: 04/20/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Needle-knife fistulotomy (NKF) is used as a rescue technique for difficult cannulation. However, the data are limited regarding the use of NKF for primary biliary cannulation, especially when performed by beginners.
AIM To assess the effectiveness and safety of primary NKF for biliary cannulation, and the role of the endoscopist’s expertise level (beginner vs expert).
METHODS We retrospectively evaluated the records of 542 patients with naïve prominent bulging papilla and no history of pancreatitis, who underwent bile duct cannulation at a tertiary referral center. The patients were categorized according to the endoscopist’s expertise level and the technique used for bile duct cannulation. We assessed the rates of successful cannulation and adverse events.
RESULTS The baseline characteristics did not differ between the experienced and less-experienced endoscopists. The incidence rate of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) was significantly affected by the endoscopist’s expertise level in patients who received conventional cannulation with sphincterotomy (8.9% vs 3.4% for beginner vs expert, P = 0.039), but not in those who received NKF. In the multivariable analysis, a lower expertise level of the biliary endoscopist (P = 0.037) and longer total procedure time (P = 0.026) were significant risk factor of PEP in patients who received conventional cannulation with sphincterotomy but only total procedure time (P = 0.004) was significant risk factor of PEP in those who received NKF.
CONCLUSION Primary NKF was effective and safe in patients with prominent and bulging ampulla, even when performed by less-experienced endoscopist. We need to confirm which level of endoscopist’s experience is needed for primary NKF through prospective randomized study.

Abstract
Introduction: Endoscopic Retrograde Cholangio-Pancreatography (ERCP) applications are rapidly evolving toward increasingly complex therapeutic approaches alongside with technological innovations. There are no globally agreed indications on the ERCP training path, which often requires too much time and does not always guarantee adequate skills.Areas covered: Frequency and difficulty of execution are the main objective criteria on which to draw up a training program: novel trainees should approach ERCP first through the simplest and most frequent procedures. An extensive use of training models would reduce the patient's performer-related risks. Amongst a wide variety of models, mechanical simulators have received large approval. In fact, they can be best-suited to each trainee's learning curve thanks to their precision and safety and by virtue of the unlimited repeatability of their use. However, more solid evidences are still needed.Expert opinion: Hands-on ERCP training should systematically employ mechanical simulators at least in the early stages of the learning process. An implementation of these models through sensors that objectively detect abnormalities in the movements would provide detailed feedbacks and deeper awareness. Simulators might also be useful for expert endoscopists to refine their skills. Rapid prototyping and 3D printing might be the way to create customized training models for successful training programs.

Abstract
The advancement of artificial intelligence (AI) has facilitated its application in medical fields. However, there has been little research for AI-assisted endoscopy, despite the clinical significance of the efficiency and safety of cannulation in the endoscopic retrograde cholangiopancreatography (ERCP). In this study, we aim to assist endoscopists performing ERCP through automatic detection of the ampulla and the identification of cannulation difficulty. We developed a novel AI-assisted system based on convolutional neural networks that predict the location of the ampulla and the difficulty of cannulation to the ampulla. ERCP data of 531 and 451 patients were utilized in the evaluation of our model for each task. Our model detected the ampulla with mean intersection-over-union 64.1%, precision 76.2%, recall 78.4%, and centroid distance 0.021. In classifying the cannulation difficulty, it achieved the recall of 71.9% for the class of easy cases and that of 61.1% for that of difficult cases. Remarkably, our model accurately detected AOV with varying morphological shape, size, and texture on par with the level of a human expert and showed promising results for recognizing cannulation difficulty. It demonstrated its potential to improve the quality of ERCP by assisting endoscopists.

Abstract
Background/Aims The work environment in which endoscopic retrograde cholangiopancreatography (ERCP) is conducted has influence on its efficacy and safety. We aimed to assess the current status of ERCP work environments and to investigate the trends associated with the basic techniques of ERCP in Korea. Methods The work environment and information on the basic techniques of ERCP were acquired by the Korean Pancreatobiliary Association (KPBA) through a national survey in 2019. The survey was performed at the KPBA conference in 2019. The contents of survey comprised of the current environment of ERCP, preparation before ERCP, and the preferred basic techniques used in ERCP. Results Completed questionnaires were returned from 84 KPBA members. The mean ERCP volume per year was approximately 500. About 60% (50/84) reported that they worked with a dedicated ERCP team with experienced nurses. Two-thirds (57/84, 68%) answered that they had a fluoroscopy room used solely for ERCP procedures. All respondents intravenously hydrated the patient to prevent post-ERCP pancreatitis (84/84, 100%). The preferred procedural sedations were balanced propofol sedation (50%) and midazolam-only sedation (47%). Wire-guided cannulation was most commonly used for selective cannulation (81%). Endoscopic retrograde biliary drainage was preferred over endoscopic nasobiliary drainage (60% vs 22%). The initial method of ampullary intervention was endoscopic sphincterotomy in 60%. Conclusions Data from the survey involving a large number of Korean ERCP doctors revealed considerable variabilities with regard to the work environment and basic techniques of ERCP in Korea. The study provides information regarding the current trends of ERCP that can be used to establish ERCP standards in Korea.

Characteristics and Outcomes of ERCP at a Canadian Tertiary Centre: Initial Results from a Prospective High-Fidelity Biliary Endoscopy Registry. J Can Assoc Gastroenterol 2021; 4:78-83. [PMID: 33855265 PMCID: PMC8023809 DOI: 10.1093/jcag/gwaa007] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Accepted: 02/06/2020] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is an essential procedure in the management of pancreatic and biliary disease. While its role is firmly established, further well-designed prospective ERCP research is required, as a large portion of previous work has employed retrospective or administrative methodologies, both prone to potential biases. The aim of the Calgary Registry for Advanced and Therapeutic Endoscopy (CReATE) is to be a high-fidelity prospective multicentre registry. METHODS The study population consisted of consecutive adult ERCP patients from September 2018 to September 2019. Informed consent was acquired for each patient. All relevant preprocedural, procedural, peri-procedural and postprocedural data were captured in real time by a full-time third-party research assistant directly observing procedures. Outcomes were ascertained by comprehensive medical record review and patient phone interview 30 days after the index procedure. RESULTS Five endoscopists performed 895 ERCP procedures, 90.1% of which were deemed successful. Suspected choledocholithiasis was the most common indication for ERCP, followed by suspected or confirmed stricture(s), at 61.0% and 29.5%, respectively. 61.0% of procedures were performed on ERCP-naive patients. Post-ERCP pancreatitis occurred following 4.9% of procedures, with clinically significant bleeding or perforation occurring following 1.8% and 0.1% of procedures, respectively. DISCUSSION Through 12 months, CReATE captured 895 procedures prospectively, with each entry containing over 300 data fields. Active expansion to additional tertiary centres is underway, and this will enhance the existing data pool. CReATE has the potential to improve multiple facets of ERCP, including training, optimal procedural techniques, mitigation of adverse events and personalized patient care.

Dig Dis 2021; 40:85-96. [PMID: 33684915 DOI: 10.1159/000515692] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Accepted: 03/04/2021] [Indexed: 02/02/2023]
Abstract
BACKGROUND In the setting of a naïve papilla, biliary cannulation is a key step in successfully performing endoscopic retrograde cholangiography. Difficult biliary cannulation (DBC) is associated with an increased risk of post-ERCP pancreatitis and failure of the whole procedure. SUMMARY Recommendations for biliary cannulation can be divided into (a) measures to reduce the likelihood of a difficult papilla situation a priori and (b) rescue techniques in case the endoscopist is actually facing DBC. (a) Careful inspection of the papillary anatomy and optimizing its accessibility by scope positioning is fundamental. A sphincterotome in combination with a soft-tip hydrophilic guidewire rather than a standard catheter with a standard guidewire should be used in most situations. (b) The most important rescue techniques are needle-knife precut, double-guidewire technique, and transpancreatic sphincterotomy. In few cases, anterograde cannulation techniques are needed. To this regard, the EUS-guided biliary drainage followed by rendezvous is increasingly used as an alternative to percutaneous transhepatic biliary drainage. Key Messages: Biliary cannulation can be accomplished with alternative retrograde or less frequently by salvage anterograde techniques, once conventional direct cannulation attempts have failed. Considering recent favorable data for the early use of transpancreatic sphincterotomy, an adopted version of the 2016 European Society for Gastrointestinal Endoscopy (ESGE) algorithm on biliary cannulation is proposed.

Abstract
The landscape of advanced endoscopy continues to evolve as new technologies and techniques become available. Although postgraduate advanced endoscopy fellowships have traditionally centered on ERCP and diagnostic EUS, the breadth of training has increased over the years in response to the ever-growing demand for therapeutic endoscopy. The increasing diversity and complexity of emerging endoscopic techniques accompanied by the shift in focus toward competency-based medical education requires innovative changes to the curriculum that will ensure adequate training yet without compromising best patient practices. The purpose of this review is to highlight the expansive array of advanced endoscopic procedures and the challenges of both defining and measuring competence during training. All authors are interventional endoscopists at their respective institutions performing these complex procedures, as well as training fellows in these techniques. We share our perspectives based on our experience navigating through these issues at our institutions and discuss strategies to standardize training and how to potentially incorporate these measures in the process of credentialing and privileging in endoscopy.

Abstract
BACKGROUND Lack of forward-viewing endoscopy experience impairs training in endoscopic retrograde cholangiopancreatography (ERCP). We evaluated the effect of ERCP mechanical simulator (EMS) practice on ERCP performance by surgical trainees. PATIENTS AND METHODS 12 surgical trainees without endoscopy experience were randomly allocated to non-EMS (n = 6) programs or to EMS (n = 6) programs with coaching and 20 hours of supervised EMS practice. All trainees then received supervised hands-on clinical ERCP training. Trainers provided verbal instructions and hands-on assistance, and took over if cannulation was not achieved by 20 minutes. Blinded trainers rated clinical performance. RESULTS Each group performed 150 clinical ERCPs. Biliary cannulation success was significantly higher in the EMS vs. the non-EMS group (P = 0.006), with shorter mean times (in minutes) for intubation, cannulation, and completion (all P < 0.001). EMS trainees showed a significantly better mean performance score (P = 0.006). In multivariate analysis, after adjusting for case sequence, CBD stone, complexity, and EMS training, the effect of EMS practice on odds for successful cannulation remained highly significant (odds ratio [OR] 2.10 [95 %CI 1.46 - 3.01]). At 6 months EMS trainees still had better cannulation success vs. non-EMS controls (P = 0.045); no difference was observed after 1 year. CONCLUSIONS EMS practice shortens the ERCP early learning curve of inexperienced surgical trainees, improves clinical success in selective biliary cannulation, and may reduce complications.

Abstract
BACKGROUND ERCP training models are very different in terms of anatomical differences, ethical issues, storage problems, realistic tactile sensation, durability and portability. There is no easy way to select an optimized model for ERCP training. If the ERCP training model could be made as a soft silicone model using 3D printing technique, it would have numerous advantages over the models presented so far. The purpose of this study was to develop an optimized ERCP training model using a 3D printing technique and to try to find ways for implementing various practical techniques. METHODS All organ parts of this model were fabricated using silicone molding techniques with 3D printing. Especially, various anatomy of the ampulla of Vater and common bile duct (CBD) were creatively designed for different diagnostic and therapeutic procedures. In order to manufacture each of the designed organ parts with silicone, a negative part had to be newly designed to produce the molder. The negative molders were 3D printed and then injection molding was applied to obtain organ parts in silicone material. The eight different types of ampulla and CBD were repeatedly utilized and replaced to the main system as a module-type. RESULTS ERCP training silicone model using 3D technique was semi-permanently used to repeat various ERCP procedures. All ERCP procedures using this model could be observed by real-time fluoroscopic examination as well as endoscopic examination simultaneously. Using different ampulla and CBD modules, basic biliary cannulation, difficult cannulation, stone extraction, mechanical lithotripsy, metal stent insertion, plastic stent insertion, and balloon dilation were successfully and repeatedly achieved. Endoscopic sphincterotomy was also performed on a specialized ampulla using a Vienna sausage. After repeat procedures and trainings, all parts of organs including the ampulla and CBD modules were not markedly damaged or deformed. CONCLUSIONS We made a specialized ERCP training silicon model with 3D printing technique. This model is durable, relatively cheap and easy to make, and thus allows the users to perform various specialized ERCP techniques, which increases its chances of being a good ERCP training model.

Abstract
OBJECTIVES Successful biliary cannulation is a prerequisite and important component of endoscopic retrograde cholangiopancreatography, but conventional cannulation methods (CCMs) have a postendoscopic retrograde cholangiopancreatography pancreatitis (PEP) rate of 14.1% in patients at high risk for PEP. The aim of this study was to evaluate the effectiveness and safety of needle-knife fistulotomy (NKF), compared with a CCM, when used for primary biliary access in patients at high risk for developing PEP. METHODS A total of 207 patients with one or more risk factors for PEP were prospectively enrolled. The patients were randomly allocated to one of 2 groups according to the primary biliary cannulation technique (NKF or CCM). We compared biliary cannulation success rates, cannulation and procedure times, and the incidence of adverse events, including PEP, between the groups. RESULTS The mean number of PEP risk factors was similar between the groups (NKF, 2.2 ± 1.0; CCM, 2.2 ± 0.9). PEP occurred in 8 patients in the CCM group and in no patients in the NKF group (9.2% vs 0%, P < 0.001). The rates of other adverse events did not differ between the groups. The biliary cannulation success rate was high in the NKF group, but relatively low in the CCM group, possibly because of the stringent failure criteria aimed at reducing PEP. However, the mean cannulation and total procedural times were longer in the NKF group than in the CCM group. DISCUSSION NKF is an effective and safe procedure to gain primary biliary access in patients at high risk for developing PEP. ClinicalTrials.gov, NCT02916199.

Abstract
BACKGROUND AND AIMS The Assessment of Competency in Endoscopy (ACE) tools for colonoscopy and EGD were both put forth by the Training Committee of the American Society for Gastrointestinal Endoscopy (ASGE), with the intent of providing teachers and programs a means to continuously assess fellow skills in these procedures throughout their years of training. Despite the availability of the tools, there are no data that define when competency in EGD has been reached. The goal of this study is to validate the EGD ACE tool (ACE-E) and for the first time describe learning curves and competency benchmarks for EGD by examining a large national cohort of trainees. METHODS In a prospective, multicenter trial, gastroenterology fellows at all stages of training had their core cognitive and motor skills in EGDs assessed by staff using the ACE-E tool. Evaluations occurred at set intervals of every 50 procedures over an academic year. Like the previously reported and validated ACE tool for colonoscopy, the ACE-E tool uses a 4-point grading scale to define a skills continuum from novice to competent. At each assessment interval, average scores for each skill were computed and overall competency benchmarks for each skill were established using the contrasting groups method. RESULTS Ninety-six GI fellows at 10 U.S. academic institutions had 1002 EGDs assessed using the ACE-E tool. Average ACE-E scores of 3.5 were found to be inclusive of all minimal competency thresholds identified for each core skill. In addition, independent intubation of the second part of the duodenum (D2) at rates of ≥95% as well as D2 intubation times of ≤4.75 minutes and average total procedure times of ≤12.5 minutes were identified as the points separating competent from non-competent groups. Although the average fellow achieves the D2 intubation rates and time criteria by 100 and 150 procedures, respectively, achieving ACE-E threshold scores on the remaining metrics was typically not achieved until 200 to 250 procedures. CONCLUSIONS Nationally generalizable learning curves for EGD skills in GI fellows are described. Average ACE-E scores of 3.5, independent D2 intubation rates of 95%, and D2 intubation times of ≤4.75 minutes are recommended as minimum competency criteria. On average, it takes GI fellows only 150 procedures to simply drive the scope adequately but 250 procedures to achieve minimum competence in the remaining cognitive and motor skills. The D2 intubation rate threshold and learning curve found in this multicenter cohort using the ACE-E tool are similar to those recently described by researchers in the United Kingdom; however, development of cognitive and overall competence requires a higher procedure threshold than previously described.

Abstract
BACKGROUND AND AIMS Selective cannulation of the desired duct is a key element in ERCP procedures and an important step in the training of fellows. However, there is limited data about technical success and patient safety for ERCPs conducted in a training setting.We aimed to evaluate the impact of trainee involvement on the cannulation technique and procedure related outcomes at ERCP. MATERIALS AND METHODS We conducted an observational study of all ERCP conducted in an endoscopy unit with an on-going training program. Patient related data and procedure-related data (method of cannulation, time to cannulation, degree of trainee involvement, technical success and procedure-related adverse events) were collected using a standard form. The method of cannulation, time to cannulation and procedure-related adverse events were compared between ERCPs with trainee involvement and those without. RESULTS 641 consecutive ERCPs were evaluated and 474 native papilla cases performed by 4 trainers and 3 trainees were included in the final analysis. Trainees were involved in 171 procedures (36.1%), achieving cannulation of the desired duct in 50.8% of the cases. Cannulation rates were similar in the trainee group compared to the control group (91.7% vs. 88.7%) and there was no increase in the rate of adverse events. However, cannulation time was significantly longer in the trainee group with a significant increase in the rate of precut use (32.1% vs. 23.4%, p < 0.001). CONCLUSIONS Trainee involvement resulted in longer cannulation times and increased use of precut sphincterotomy, but, was not associated with an increased risk of procedure related adverse events.

Abstract
BACKGROUND AND AIM Hands-on endoscopic retrograde cholangiopancreatography (ERCP) training is essential for trainees to grasp the technique. Cannulation success rate (CSR) is considered one of the main indicators of competency of trainees. We aimed to investigate whether patient-related factors had an impact on the CSR of trainees. METHODS A post hoc analysis of data from two multicenter studies (NCT02002650 and NCT03057769) was conducted. Patients aged 18-90 years with native papilla undergoing ERCP were eligible for this study. Only procedures involving trainees in centers strictly following "10-min criteria" for initial cannulation were enrolled. Primary outcome was CSR by trainees. RESULTS From December 2013 to October 2017, 20 trainees in four centers were involved in initial cannulation in 1044 patients with native papilla. Primary CSR by trainees was 61.0% (436/715), 31.5% (70/222) and 44.9% (48/107) in patients with common bile duct stone (CBDS), biliary stricture (BS) and other indications, respectively (P < 0.001). In multivariate analysis, indication of BS (OR, 0.31; 95% CI, 0.22-0.44; P < 0.001) and presence of type A diverticulum (OR, 1.69; 95% CI, 1.23-2.33; P = 0.001) were both independently associated with cannulation success of trainees. Biliary infection was significantly higher in the BS than in the CBDS group (3.6% vs 0.7%, P = 0.004), whereas other post-ERCP complications were comparable between the two groups. CONCLUSIONS Indication of BS and the presence of type A diverticulum were independently associated with the success of cannulation by trainees. These findings indicate that greater effort is needed for trainees to improve the ability of cannulation in BS.

Abstract
Background The aim of this prospective study was to evaluate the clinical application value of single-operator cannulation technology (SOCT) for endoscopic retrograde cholangiopancreatography (ERCP). Material/Methods Sixty-nine patients prepared for ERCP were prospectively recruited from February 2014 to January 2017 in the 4th People’s Hospital of Jinan. The included 69 patients were randomly divided into an experiment group (n=36) and a control group (n=33). Patients in the experiment group underwent SOCT procedure of ERCP and patients in the control group received the regular procedure of ERCP. The cannulation time, number of cannulations, number of attempts at cannulation, and ERCP procedure-relevant complications were recorded and compared between the 2 groups. Results All of the included 69 patients successfully finished the ERCP procedure, with no peri-operative deaths. The median duration of cannulation for the experiment group was 7.4 (2.3~35.1) min and 7.1 (2.9~26.1) min for the control group, with no significant difference (p>0.05). The distribution of different cannulation periods and cannulation attempts were not significantly different between the 2 groups (p>0.05). The major complications relevant ERCP procedure were pancreatitis and infection. The incidence rate of pancreatitis and infection were 2.8% and 2.8% in the experiment group and 3.0% and 0.0% in control group, and the difference between groups was not significant (p>0.05). Conclusions Compared with regular ERCP, SOCT achieved the same effects without the help of an experienced assistant, which could make the procedure useful in primary hospitals.

Abstract
Endoscopic-retrograde-cholangiopancreatography (ERCP) is now a vital modality with primarily therapeutic and occasionally solely diagnostic utility for numerous biliary/pancreatic disorders. It has a significantly steeper learning curve than that for other standard gastrointestinal (GI) endoscopies, such as esophagogastroduodenoscopy or colonoscopy, due to greater technical difficulty and higher risk of complications. Yet, GI fellows have limited exposure to ERCP during standard-three-year-GI-fellowships because ERCP is much less frequently performed than esophagogastroduodenoscopy/colonoscopy. This led to adding an optional year of training in therapeutic endoscopy. Yet many graduates from standard three-year-fellowships without advanced training intensely pursue independent/unsupervised ERCP privileges despite inadequate numbers of performed ERCPs and unacceptably low rates of successful selective cannulation of desired (biliary or pancreatic) duct. Hospital credentialing committees have traditionally performed ERCP credentialing, but this practice has led to widespread flouting of recommended guidelines (e.g., planned privileging of applicant with 20% successful cannulation rate, or after performing only 7 ERCPs); and intense politicking of committee members by applicants, their practice groups, and potential competitors. Consequently, some gastroenterologists upon completing standard fellowships train and learn ERCP “on the job” during independent/unsupervised practice, which can result in bad outcomes: high rates of failed bile duct cannulation. This severe clinical problem is indicated by publication of ≥ 12 ERCP competency studies/guidelines during last 5 years. However, lack of mandatory, quantitative, ERCP credentialing criteria has permitted neglect of recommended guidelines. This work comprehensively reviews literature on ERCP credentialing; reviews rationales for proposed guidelines; reports problems with current system; and proposes novel criteria for competency. This work advocates for mandatory, national, written, minimum, quantitative, standards, including cognitive skills (possibly assessed by a nationwide examination), and technical skills, assessed by number performed (≥ 200-250 ERCPs), types of ERCPs, success rate (approximately ≥ 90% cannulation of desired duct), and letters of recommendation by program director/ERCP mentor. Mandatory criteria should ideally not be monitored by a hospital committee subjected to intense politicking by applicants, their employers, and sometimes even competitors, but an independent national entity, like the National Board of Medical Examiners/American Board of Internal Medicine.

Abstract
In the last two decades, endoscopic retrograde cholangiopancreatography (ERCP) has evolved from a diagnostic procedure to an almost exclusively therapeutic one. Contemporaneously, many different catheters have become available for cannulation and special techniques have also been developed for difficult cases. ERCP is a skill demanding procedure that can lead to severe complications and death. Teaching ERCP is the most difficult task in an endoscopic training program. Training programs in ERCP must be effective, standardized and structured. Furthermore, robust standards for certification and revalidation are required to ensure ERCP as effective and as safe as possible.

ERCP practice beyond the training period - bridging the gap between guidelines and real-life practice: a single operator experience of 679 procedures. ACTA ACUST UNITED AC 2019; 57:151-158.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography has evolved significantly in recent years. The increase in complexity and range of applications has not been adequately reflected in an improvement of training methods for ERCP, with many endoscopists failing to meet required performance standards during their training period and limited available data on their performance immediately after completing training. We aimed to analyze the performance of an independent operator from a developing country after the completion of formal training with regard to procedure and patient-related outcomes. METHODS We conducted an observational study of ERCPs performed by a young endoscopist from a referral center. Data about the procedure, cannulation technique (including use of precut), trainee involvement and procedure-related outcomes was retrieved and analyzed from a prospectively maintained database on quality in ERCP (the QUASIE initiative). RESULTS Data from 679 consecutive ERCPs conducted or supervised by one endoscopist with < 200 independent procedures prior to the study period were included in the final analysis. Cannulation rates significantly improved over time, from 90% to 96% (p = 0.016). Use of precut techniques changed significantly over time, with an initial increase followed by a subsequent decrease as overall cannulation rates improved. Trainee involvement was significantly associated with prolonged cannulation times (p = 0.003) and use of precut (p = 0.001), but did not impact on technical success or patient safety. CONCLUSIONS Independent practice of ERCP after the training period is characterized by ongoing changes in technique, especially with regard to cannulation and use of precut, showing significant improvements in performance over time.

Abstract
Background Current recommendations on training in endoscopic retrograde cholangiopancreatography are predicated on a performance-centred approach designed to ensure that trainees achieve appropriate skills. We aimed to analyse how competence in endoscopic retrograde cholangiopancreatography is defined in the literature and what proportion of trainees actually reach this threshold. Methods We conducted a systematic MEDLINE search for studies reporting on endoscopic retrograde cholangiopancreatography training programmes in a clinical setting. The main outcome measure was threshold for achieving competence in endoscopic retrograde cholangiopancreatography; the secondary outcome measure was assessment of trainee performance. Quality was assessed using the Cochrane Risk of Bias tool and the Methodological Index for Non-Randomized Studies criteria. Results Of 522 initially identified articles, 20 were included in the analysis; most studies showed a high risk of bias. Cannulation rate of the desired duct was the main marker of competence in all studies; however, only 8/20 studies reported on the performance of individual trainees, who achieved their respective standard of competence in only 25.6% of reported cases. Conclusions Current literature identifies cannulation rate of a native papilla to be the most appropriate measure of endoscopic retrograde cholangiopancreatography competence; however, most trainees do not reach predefined competence thresholds. Furthermore, due to the limitations of available studies, the most appropriate competence measure remains subject for debate.

Abstract
Despite improvements in endoscopic technologies and accessories, development of advanced endoscopy fellowship programs, and advances in ancillary imaging techniques, biliary cannulation in endoscopic retrograde cholangiopancreatography (ERCP) can still be unsuccessful in up to 20% of patients, even in referral centers. Once cannulation has been deemed to be difficult, the risk of post-ERCP pancreatitis and technical failure inherently increases. A number of factors, including endoscopist experience and patient anatomy, have been associated with difficult biliary cannulation, but predicting a case of difficult cannulation a priori is often not possible. Numerous techniques such as pancreatic guidewire and stenting, early pre-cut, and rendezvous may be employed when standard approaches fail. Data regarding the rate of success and adverse events of these techniques have been variable, though most studies suggest that pancreatic duct stenting generally reduces the rate of post-ERCP pancreatitis in instances of difficult biliary cannulation. Here we provide a review on difficult biliary cannulation and discuss how the choice of which techniques to employ and how to best employ them should be individualized and take into account the skill of the endoscopist, the disorder being treated, the anatomy of the patient, and the available biomedical literature.

Abstract
Training in endoscopic retrograde cholangiopancreatography (ERCP) requires the development of technical, cognitive, and integrative skills well beyond those needed for standard endoscopic procedures. So far, there are limited data regarding what constitutes competency in ERCP, including achievement and maintenance. Recent studies have highlighted overall procedural numbers are not enough to warrant competency, although more is better. We performed a comprehensive literature search until June 2017 using predetermined search terms to identify relevant articles and summarized their results as a narrative review. Selective native papilla deep cannulation should be used as a benchmark for assessing successful cannulation. Accurate and validated ERCP performance measures are needed to develop a curriculum that allows transition from numbers-based competency. However, available guidelines fail to state what degree of hands-on involvement is required by the trainee for the case to be counted in their overall procedural numbers. Qualitative assessment of competency should be done by trained raters using specially designed assessment tools. Competence continues to increase with practice following formal training in a fairly steady manner. The learning curve for overall common bile duct cannulation success may be a readily available surrogate for individual trainee progression and may correspond to learning curves for therapeutic interventions.

Abstract
Objective There are no reports on whether or not trainees can safely carry out endoscopic procedures for the removal of common bile duct (CBD) stones. The aim of this study was to investigate the efficacy and safety of endoscopic treatments for CBD stones by trainees. Methods Endoscopic retrograde cholangiopancreatography (ERCP) was performed in 1,016 consecutive patients at our institution during the 6-year study period. The endoscopically treated patients with CBD stones were included in this study. Physicians who had experienced ≥300 ERCP procedures were defined as experts, while those who had experienced <300 procedures were defined as trainees. The trainees were replaced by an expert when they could not achieve the established criteria. Patients were divided into the following three groups to retrospectively examine the patients' backgrounds, details of endoscopic treatments, and intra-/post-operative complications: Group A, completed by trainees under supervision of an expert; B, treated by an expert who switched in for a trainee in the middle of the procedure; and C, completed by an expert. Results A total of 325 patients with CBD stones underwent endoscopic treatments. The number included in Groups A, B, and C was 176, 102, and 47, respectively. The bile duct catheter insertion successes rates for Groups A, B, and C were 99.0%, 97.1%, and 100% (p=0.09), and the complete stone removal rates were 94.2%, 94.8%, and 100%, respectively (p=0.07), showing no significant difference among the three groups. Furthermore, the frequency of intra-/post-operative complications was not significantly different among the three groups (p=0.48, p=0.12, respectively). Conclusion This study showed that trainees could safely perform endoscopic procedures in accordance with our facility's criteria during ERCP.

Abstract
The Korean Society of Gastrointestinal Endoscopy (KSGE) developed a gastrointestinal (GI) endoscopy board in 1995 and related regulations. Although the KSGE has acquired many specialists since then, the education and training aims and guidelines were insufficient. During GI fellowship training, obtaining sufficient exposure to some types of endoscopic procedures is difficult. Fellows should acquire endoscopic skills through supervised endoscopic procedures during GI fellowship training. Thus, the KSGE requires training guidelines for fellowships that allow fellows to perform independent endoscopic procedures without supervision. This document is intended to provide principles that the Committee of Education and Training of the KSGE can use to develop practical guidelines for granting privileges to perform accurate GI endoscopy safely. The KSGE will improve the quality of GI endoscopy by providing guidelines for fellowships and supervisors.

Abstract
BACKGROUND AND STUDY AIMS Findings in the literature are conflicting on whether trainee involvement in endoscopic retrograde cholangiopancreatography (ERCP) procedures is detrimental to cannulation success rates. We addressed this in a prospective study, where cannulation success with or without trainee presence was the primary outcome measure. PATIENTS AND METHODS We prospectively recorded data on 2 senior endoscopists and their trainees over an 18-month period for ERCPs in patients with a virgin ampulla. Presence or absence of a trainee at ERCP procedures was pragmatic, reflecting their other service or training commitments or annual leave. For trainee presence, the training protocol allowed them 6 minutes of supervised time in which to achieve biliary cannulation after reaching the ampulla. Study outcome measures included cannulation success, time to cannulation, technique, whether this was achieved independently by the trainee, and complications. RESULTS There were 219 procedures recorded and analyzed (134 with a trainee, 85 without). Three trainees were involved. Selective biliary cannulation was achieved in 201 (92 %) of cases. When a trainee was present, cannulation was successful in 122/134 procedures (91 %), compared to 79/85 (93 %) with a senior endoscopist alone ( P = 0.8, Fisher's exact test). Mean time to biliary cannulation with a trainee present was 7 minutes, compared with 5 minutes with no trainee. Mean time for successful independent cannulation by the trainee was 4 minutes, and 9 minutes for a consultant following a trainee's attempt. There were no serious adverse events. CONCLUSION Our study shows that with this training protocol, involvement of a trainee on a routine secondary care ERCP list does not impair biliary cannulation success, and does not prolong a subsequent attempt by the senior endoscopist if initially unsuccessful. These findings support the involvement of trainees in routine ERCP lists with this training protocol.

Abstract
Background. Several previous studies assessed the competence in endoscopic retrograde cholangiopancreatography (ERCP) using the bile duct cannulation success rate. However, the cannulation time is also important, because a long cannulation time was reported to be a risk factor for post-ERCP pancreatitis. Aim. To determine the number of ERCP procedures required for short cannulation time of the bile duct. Methods. We retrospectively analyzed 605 ERCP procedures performed for bile duct cannulation in patients with native papilla at our institution between March 2012 and December 2015. The successful procedures were divided into 2 groups: group L and group S (cannulation time > 15 minutes and ≤15 minutes, resp.). An analysis of the relationship among the biliary cannulation time, ERCP experience, and other factors was then conducted. Results. Multivariate analysis showed that the ERCP experience of ≤300 procedures (odds ratio, 2.080; 95% confidence interval, 1.337–3.142; P = 0.001) and malignant biliary stricture due to pancreatic cancer (odds ratio, 1.912; 95% confidence interval, 1.072–3.412; P = 0.028) were found to be significantly associated with a cannulation time of >15 minutes. Conclusions. Our findings suggested that an ERCP experience of ≤300 procedures and malignant biliary stricture due to pancreatic cancer were associated with prolonged biliary cannulation time.

Abstract
Background There is no consensus on what constitutes adequate training for needle knife precut sphincterotomy. Objective The purpose of this study was to determine the number of procedures required before effective and safe precut sphincterotomy can be achieved. Methods This retrospective study examined the cumulative experience of a single endoscopist from January 2006-December 2015. Precut sphincterotomy success and complication rates were analyzed as a function of number of procedures performed. Acceptable success and complication rates were defined as 85% and 10% respectively. A one-sided binomial test was used to test success and complication rates of every 25 precut sphincterotomies performed. Results The index endoscopic retrograde cholangiopancreatography was successful in 141/158 (89.2%) patients who underwent precut sphincterotomy. This increased to 148/158 (93.7%) when endoscopic retrograde cholangiopancreatography was repeated on another day. Six precut sphincterotomies were required to achieve an 85% success probability. This was maintained consistently above 85% after 13 precuts, and was significantly higher (91.2%; p = 0.029) than 85% at the 125th precut. Bleeding and pancreatitis developed in 2/158 (1.3%) and 5/158 (3.2%). Probability of either complications remained below 5% after 50 precuts. No perforation occurred. Conclusion At least 13 precut sphincterotomies were required to achieve a sustained success rate greater than 85%. The probability of bleeding or pancreatitis was less than 5% after 50 precut sphincterotomies.

Abstract
INTRODUCTION The diversity, technical skills required, and risk inherent to advanced endoscopy techniques all contribute to complex training curricula and steep learning curves. Since trainees develop endoscopy skills at different rates, there has been a shift towards competency-based training and certification. Validated endoscopy performance measures for trainees are, therefore, necessary. The aim of this systematic review was to describe and critically assess the existing evidence regarding measures of performance for trainees in advanced endoscopy. METHODS A systematic review of the literature from January 1980 to January 2016 was carried out using the MEDLINE, EMBASE, CENTRAL, and ISI Web of knowledge databases. MeSH terms related to 'advanced endoscopy' and 'performance' were applied to a highly sensitive search strategy. The main outcomes were face, content, and construct validity, as well as reliability. RESULTS The literature search yielded 1,662 studies and 77 met the inclusion criteria after abstract and full-text review (endoscopic retrograde cholangiopancreatography (ERCP)=23, endoscopic ultrasound (EUS)=30, colonoscopic polypectomy (CP)=11, balloon-assisted enteroscopy (BAE)=7, luminal stenting=3, radiofrequency ablation (RFA)=2, and endoscopic muscosal resection (EMR)=1). Good validity and reliability were found for measurement tools of overall performance in ERCP, EUS and CP, with applications for both patient-based and simulator training models. A number of specific technical skills were also shown to be valid measures of performance. These include: selective biliary cannulation, sphincterotomy, biliary stent placement, stone extraction and procedure time for ERCP; pancreatic solid mass T-staging, EUS-guided fine needle aspiration (EUS-FNA) procedure time, number of EUS-FNA passes and puncture precision for EUS; procedure time and en bloc resection rate for CP; retrograde fluoroscopy time for BAE; and mean number of endoscopy sessions required to achieve complete eradication of intestinal metaplasia (CIEM) for RFA. The evidence for EMR and luminal stenting is of insufficient quality to make recommendations. CONCLUSIONS We have identified multiple valid and readily available performance measures for advanced endoscopy trainees for ERCP, EUS, CP, BAE and RFA procedures. These tools should be considered in advanced endoscopy training programs wishing to move away from apprenticeship-based training and towards competency-based learning with the help of patient-based and simulator tools.

Abstract
Advanced endoscopy has evolved from diagnostic ERCP to an ever-increasing array of therapeutic procedures including EUS with FNA, ablative therapies, deep enteroscopy, luminal stenting, endoscopic suturing and endoscopic mucosal resection among others. As these procedures have become increasingly more complex, the risk of potential complications has also risen. Training in advanced endoscopy involves more than obtaining a minimum number of therapeutic procedures. The means of assessing a trainee's competence level and ability to practice independently continues to be a matter of debate. The use of quality indicators to measure performance levels may be beneficial as more advanced techniques and procedures become available.

Abstract
BACKGROUND AND STUDY AIM Endoscopy society guidelines recommend a minimum of 200 cases for endoscopic retrograde cholangiopancreatography (ERCP) trainees in order to ensure competency and quality standards. However, there are few data regarding procedure-related complication rates and added risk for patients during this learning process. We aimed to evaluate the correlation between trainee caseload and procedure- and patient-related outcomes in an ERCP training program, and to assess the risk factors for ERCP failure and complications. PATIENTS AND METHODS We conducted a prospective study of all procedures performed in the ERCP training program at Colentina Clinical Hospital, Bucharest, Romania. Relevant data for each procedure (diagnosis, cannulation method, outcome, and complications during the following 30 days) as well as operator experience were documented. Univariable and multivariable analysis of the risk factors for ERCP failure and complications was done by analyzing the procedures completed by expert and trainee endoscopists during the study period. RESULTS The analysis included 534 ERCPs performed by 1 expert and 3 supervised trainees during a 12-month period. Technical success rates were comparable in the trainee and expert groups, and no statistically significant difference was found between the two groups with regard to procedure-related complications and mortality. The more experienced trainees had a better chance of successfully completing a procedure (odds ratio of 1.1 for each additional 10 ERCPs performed), but post-ERCP complications were unrelated to individual trainee caseloads on multivariable analysis. CONCLUSION The ERCP technical success rate increases with trainee experience, reflecting the learning curve of individual operators. However, the complication rates are similar across different levels of operator experience, indicating that ERCPs performed by supervised trainees imply no additional risk for patients.

Abstract
INTRODUCTION Training procedural skills in GI endoscopy once focused on threshold numbers. As threshold numbers poorly reflect individual competence, the focus gradually shifts towards a more individual approach. Tools to assess and document individual learning progress are being developed and incorporated in dedicated training curricula. However, there is a lack of consensus and training guidelines differ worldwide, which reflects uncertainties on optimal set-up of a training programme. AIMS The primary aim of this systematic review was to evaluate the currently available literature for the use of training and assessment methods in GI endoscopy. Second, we aimed to identify the role of simulator-based training as well as the value of continuous competence assessment in patient-based training. Third, we aimed to propose a structured training curriculum based on the presented evidence. METHODS A literature search was carried out in the available medical and educational literature databases. The results were systematically reviewed and studies were included using a predefined protocol with independent assessment by two reviewers and a final consensus round. RESULTS The literature search yielded 5846 studies. Ninety-four relevant studies on simulators, assessment methods, learning curves and training programmes for GI endoscopy met the inclusion criteria. Twenty-seven studies on simulator validation were included. Good validity was demonstrated for four simulators. Twenty-three studies reported on simulator training and learning curves, including 17 randomised control trials. Increased performance on a virtual reality (VR) simulator was shown in all studies. Improved performance in patient-based assessment was demonstrated in 14 studies. Four studies reported on the use of simulators for assessment of competence levels. Current simulators lack the discriminative power to determine competence levels in patient-based endoscopy. Eight out of 14 studies on colonoscopy, endoscopic retrograde cholangiopancreatography and endosonography reported on learning curves in patient-based endoscopy and proved the value of this approach for measuring performance. Ten studies explored the numbers needed to gain competence, but the proposed thresholds varied widely between them. Five out of nine studies describing the development and evaluation of assessment tools for GI endoscopy provided insight into the performance of endoscopists. Five out of seven studies proved that intense training programmes result in good performance. CONCLUSIONS The use of validated VR simulators in the early training setting accelerates the learning of practical skills. Learning curves are valuable for the continuous assessment of performance and are more relevant than threshold numbers. Future research will strengthen these conclusions by evaluating simulation-based as well as patient-based training in GI endoscopy. A complete curriculum with the assessment of competence throughout training needs to be developed for all GI endoscopy procedures.
