Impact of mechanical simulator practice on clinical ERCP performance by novice surgical trainees: a randomized controlled trial.


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.
