Endoscopic papillary balloon dilation for difficult common bile duct stones: Our experience

Background and Aims The training in esophageal stricture dilation is difficult to obtain and have few simulation models. The aim of the study was to evaluate a novel stricture simulation for training a wire-guided, controlled radial expansile (CRE) balloon dilation. Methods The study was a pretest–posttest design without a control group involving a novel simulation device for esophageal stricture. The training session involved 12 final year gastroenterology fellows from five different centers. The trainees received 2 hours of education sessions featuring didactic content, a live demonstration of step-by-step demonstration of wire-guided CRE balloon dilation and a study material on the procedure. The simulation device used was a single-use hose pipe along with a red color nonhardening modeling clay with a 5.0-to-8.0-mm hole in the center. Results All the trainees and instructor uniformly rated the model as excellent or good with simulation device being mild stiffer in haptics than of the real tissue. The mean (%) pretest scores of 39 (21.6%) improved significantly to 160 (88.8%) in mean (%) posttest questionnaire (p < 0.05). There was a significant improvement in the questionnaire of the dilation procedure after the simulation training episode. Conclusion The novel stricture simulation model had good performance evaluation and can be used to train CRE balloon dilation procedure.
