The Effectiveness of an Exclusive Cold Snare Polypectomy Snare for the Removal of Diminutive Colorectal Polyps

Study Overview
=================
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.

Conditions
-----------------
Diminutive Colorectal Polyp, Cold Snare Polypectomy, Polypectomy Snare, Complete Resection Rate, Postpolypectomy Bleeding

Intervention / Treatment
-----------------
* Device: exclusive cold polypectomy snare (Exacto cold snare, product number 00711115)
* Device: Regular polypectomy snare (Snare Master, SD-210U-10)

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Exclusive cold polypectomy snare<br>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)<br> <br> |
