WATER-POCKET ENDOSCOPIC SUBMUCOSAL DISSECTION FOR SUPERFICIAL COLORECTAL NEOPLASMS

It is essential to obtain a clear view during the endoscopic submucosal dissection (ESD) to dissect the appropriate submucosal layer. Some advantages of underwater techniques for endoscopic resection compared with air insufflation have been reported. Therefore, we aimed to investigate the feasibility and safety of water-pocket ESD (WP-ESD) for superficial colorectal neoplasms.
