研究组 & 干预措施
Exclusive cold polypectomy snare
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. The hemostatic clipping is not performed after cold snare polypectomy.
干预措施: exclusive cold polypectomy snare (Exacto cold snare, product number 00711115) (Device)
regular polypectomy snare
All colorectal polyps up to 10 mm found except for tiny hyperplastic polyps in the rectum and distal sigmoid colon are removed using a regular polypectomy 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. The hemostatic clipping is not performed after cold snare polypectomy.
干预措施: Regular polypectomy snare (Snare Master, SD-210U-10) (Device)
