Brief summary

Underwater EMR (UEMR) is an emerging technique for endoscopic resection. The purpose of this research is to observ wether the UEMR for medium-sized pedunculated polyps is safe and effective.

Interventions

PROCEDUREUEMR

(1) the colorectal lumen was completed deflated with 500-1000 mL sterile water using a flushing pump; (2) the lesion and 2-3 mm of normal mucosa surrounding the base of the polyp were snared and subsequently resected with an electrosurgical generator
