NCT02036047

Brief Summary

The use of an exclusive cold polypectomy snare enables a clean cut of diminutive colorectal polyps, resulting in an increase in the complete resection rate and a decrease in the adverse events.

Study Arms (2)

Exclusive cold polypectomy snare

EXPERIMENTAL

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.

Device: exclusive cold polypectomy snare (Exacto cold snare, product number 00711115)

regular polypectomy snare

ACTIVE COMPARATOR

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.

Device: Regular polypectomy snare (Snare Master, SD-210U-10)
