Feasibility Study of Modified Underwater Endoscopic Mucosal Resection for Colorectal Polyps.

ABSTRACT:

Objectives

Underwater endoscopic mucosal resection (UEMR) is widely performed for colorectal tumors. However, in our experience, it is sometimes difficult to keep a clear endoscopic view underwater, due to dirty fluid inflow or insufficient water pooling after grasping the polyp, or bleeding just after endoscopic resection. To compensate for such challenges, we reported modified UEMR (M-UEMR) as a procedure for snaring underwater and undergas resection. Therefore, we conducted a prospective clinical trial to investigate the safety and efficacy of M-UEMR.

Methods

This single-center prospective study was conducted at Tokushima University Hospital. Patients with 10-25 mm colorectal polyps were enrolled. The polyps were snared underwater, then infused water was removed, and the
