Injured submucosal arteries following cold snare polypectomy are significantly fewer versus those after endoscopic mucosal resection for 10-19-mm nonpedunculated colorectal polyps.

ABSTRACT:

Objectives

We compared the frequency of post-polypectomy bleeding or injured submucosal arteries between cold snare polypectomy (CSP) and endoscopic mucosal resection (EMR) for nonpedunculated colorectal polyps.

Methods

This was a prospective, randomized, single-center study. Patients who underwent CSP or EMR for 10-19-mm nonpedunculated polyps were enrolled in CSP and EMR groups, and we compared the patient and polyp characteristics, the number of clips used, clinical outcomes, adverse events, and pathological features of the resected polyps between these groups. The primary outcome was the presence of injured arteries in the submucosal layer of the resected polyps examined histologically. The secondary outcomes were immediate bleeding and delayed bleeding.
