UNDERWATER ENDOSCOPIC MUCOSAL RESECTION FOR COLORECTAL POLYPS

Abstract

Underwater endoscopic mucosal resection (UEMR) is a new hot snare polypectomy technique with electrocautery to remove gastrointestinal polyps without submucosal injection while filling the gastrointestinal lumen with water. Suctioning of luminal air and filling with water make the mucosa and submucosa “float” away from the muscularis propria. This makes snare capture easier. We describe herein the UEMR technique for colorectal polyps.
