57 Is a Traction Method (Clip-Band) Useful to Facilitate Gastric Endoscopic Submucosal Dissection?. a Prospective, Randomized, Controlled Trial in a Live Porcine Model

technique with mesna submucosal injection greatly reduced procedural challenges associated with gastric ESD, although the difference of TSD between the groups was not significant and the benefit couldn’t completely negate all relevant factors. The results of this study warrant further evaluation with larger sample sizes and multi-centric design. References: 1. Sumiyama K, et al.
