Modified underwater endoscopic mucosal resection for intermediate-sized sessile colorectal polyps

ABSTRACT:

Introduction

Underwater endoscopic mucosal resection (UEMR) is effective for treating intermediate-sized colorectal polyps. However, it is sometimes difficult to obtain visibility in underwater conditions.

Methods

This prospective, observational, single-center study included consecutive patients with intermediate-sized (10–20 mm) sessile colorectal polyps. Modified UEMR method was used to initially snare the lesion without injection or water infusion. Thereafter, water was infused until the lesion was submerged, then it was resected using electrocautery. We also evaluated the rates of complete resection and procedure-related complications.

Results

Forty-two patients with 47 polyps were enrolled in the study. The median procedure time and fluid infusion were 71 s
