Study design. ERCP simulation started with the model for selective cannulation, followed by the models for intubation of differently arranged papillas, stent placement, and sphincterotomy (at the latter model the integrated sliding carriage is pulled down for easy and rapid exchange of sphincterotomized biopapillae). Each simulated ERCP was timed using a stopwatch. In addition, sphincterotomies were videotaped for post hoc evaluation by a blinded expert.
