Effect of Time-Limited Training on Endoscopic Submucosal Dissection in an Ex Vivo Porcine Stomach Model: A Prospective Randomized Controlled Study

Abstract

Introduction Endoscopic submucosal dissection (ESD) is the first choice for superficial tumor resection. There is no report on whether the training effect is affected by limiting the operation time of each ESD operation. This study aimed to prospectively evaluate the efficiency of time-limited ESD training by using an ex vivo porcine stomach model.
