Abstract

Background/Aim: Training endoscopists to perform endoscopic retrograde cholangiopancreatography (ERCP) is critical to address the increasing patient population with pancreatobiliary diseases. Concerns remain about ERCP safety and success involving trainees. We compared the technical success and immediate adverse events between ERCP with and without trainee involvement. Methods: Retrospective analysis of 28,271 ERCP procedures in a national sample of the United States over 12 years. Demographics, procedure and fluoroscopy time, visualization and cannulation of main structures, adverse events, and technical success rates were compared between ERCP with and without trainees. Categorical variables were compared using Pearson’s chi-square test and continuous variables using a standard t-test. Univariate and multivariate regressions were performed adjusting for age, gender, ethnicity, US region, ASA class and clinical setting. Results: Approximately 49.5% of ERCPs had a trainee involved. The ampulla was visualized in 97.4% with trainee vs. 97.3% without trainee involvement (P = 0.858). The common bile duct was visualized and cannulated in 90.4% with trainees vs. 91.7% without trainees involved (P < 0.001). The ERCP was incomplete in 5.9% of cases with trainees vs. 6.4% without trainees involved (P = 0.207). Trainee participation added 8.7 min to average procedure time (aOR: 1.02, P < 0.001) and 2.0 min to fluoroscopy time (aOR: 1.00, P = 0.796). Adverse events (aOR: 0.89, P = 0.704) and technical success (aOR: 0.83, P = 0.571) were similar in both groups. Conclusions: Trainee involvement leads to increased procedure duration but is not associated with increased immediate adverse events, or technical failure. Our study supports ERCP safety and success with trainee participation.
