Background: Hands-on endoscopy workshops are popular and valuable sources for the continuing medical education of endoscopists. Concerns, however, exist regarding clinical outcomes of procedures performed during hands-on training of ERCP. Objective: We compared the success rates and complications between patients in the hands-on training courses and matched control patients. Design: A retrospective, multicenter study. Setting: Seven endoscopy centers in mainland China. Patients: All patients who underwent ERCP during hands-on training courses at GI endoscopy conferences in China between January 2002 and December 2006 were included. Main Outcome Measurements: Clinical and endoscopic characteristics, including age, sex, indication, therapeutic intervention, success rate, and complication, were collected. Differences in ERCP outcomes between domestic and foreign mentors were also compared. Conference, patient, and endoscopist-related variables were analyzed for potential risk factors associated with post-ERCP complications. Results: Nine conferences with hands-on ERCP training, including 124 patients, were held at 7 endoscopy centers. There were no significant differences in the sex ratio, age, indication, and therapeutic intervention between patients for hands-on training (n = 124) and controls (n = 124). The success rates and overall complication rates were similar between the 2 groups (91.9% vs 92.7%, respectively, P = .811; 12.9% vs 9.7%, respectively, P = .422). Domestic mentors encountered more post-ERCP complications than foreign mentors (18.0% vs 0%, respectively, P = .001). Univariate analyses showed that a large-scale conference (P = .004), first-time mentorship (P = .015), and small case volume for the mentor (P = .015) were significantly associated with post-ERCP complications. Nominal significance in univariate testing was removed when analyzed in a comprehensive multivariate setting. Limitations: A nonrandomized retrospective trial with only 7 centers (9 conferences). Conclusions: The success rate and overall complication rate were similar between patients in the hands-on training and those who had routine ERCP procedures. A large-scale conference, first-time mentorship, and small case volume for the mentor may be associated with post-ERCP complications.
