Injured Submucosal Arteries After CSP for 10-19 mm Nonpedunculated

Status Recruiting

Clinical Trial Summary

Clinical Trial Description

Cold polypectomy has the advantages of simple operation, less time-consuming and fewer complications. Guidelines have recommended cold snare polypectomy (CSP) to resect small polyps sized <9 mm. CSP was designed to improve the complete resection rate and reduce adverse events. Investigators hypothesize that CSP is better than conventional hot snare endoscopic mucosal resection (HS-EMR) in the presence of injured submucosal arteries detected in the submucosal layer for 10-19 mm nonpedunculated colorectal polyps, resulting in lower delayed bleeding after CS-EMR of 10-19 mm nonpedunculated colorectal polyps. The primary outcome measure was the presence of injured submucosal arteries detected in the submucosal layer. The secondary outcomes included immediate bleeding and the frequency of delayed bleeding requiring endoscopic treatment within 2 weeks after polypectomy. Immediate bleeding was defined as spurting or oozing which continued for more than 30 seconds. ;
