cold snare polypectomyhot snare polypectomy

cold snare polypectomy: Cold snare polypectomy was conducted for the removal of 4-10 mm pedunculated colorectal polyps.

hot snare polypectomy: Hot snare polypectomy was conducted for the removal of 4-10 mm pedunculated colorectal polyps.

Study summary

This was a non-inferiority randomized controlled trial designed to compare the efficacy and safety of cold versus hot snare polypectomy for the removal of 4-10 mm pedunculated colorectal polyps. The primary outcome was delayed postpolypectomy bleeding. The secondary outcomes included immediate postpolypectomy bleeding, procedure time, en bloc resection, complete histologic resection, use of haemostatic clips and perforation rate.
