Effect of ERCP Mechanical Simulator (EMS) Practice on Trainees' ERCP Performance in the Early Learning Period: US Multicenter Randomized Controlled Trial

In a prospective multicenter randomized controlled trial during early training, a significantly higher proportion of the biliary cannulations performed by trainees with EMS practice were successful and with faster cannulation time compared with those performed by trainees without such practice. The results provide objective evidence to support the continued evaluation of EMS practice to augment clinical training.
