Exclusive cold polypectomy snare

Experimental group

Description:

All colorectal polyps up to 10 mm found except for tiny hyperplastic polyps in the rectum and distal sigmoid colon are removed using an exclusive cold polypectomy snare (Exacto cold snare). The technique is cold snare resection of the polyp without tenting without electrocautery and then suction of the transected polyp into a trap followed by submission to the histological evaluation.
