Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

1. Background: The ideal method to remove small colorectal polyps in patients who are taking antithrombotic agents is unknown.
2. Aim: The aim of this study is to evaluate postpolypectomy bleeding and the complete retrieval rate after the removal by colon snare transection without electrocautery for small polyps in patients who are taking antithrombotic agents.
3. Design: A prospective, consecutive study.
4. Setting: Municipal hospital outpatients.
5. Interventions: Polypectomy by cold snare technique (Cold polypectomy) was performed for colorectal polyps up to 10 mm in diameter in patients who continue to take antithrombotic agents. The primary outcome measure was bleeding within two weeks after polypectomy. Secondary outcome measure was the complete retrieval rate of colorectal polyps based on the pathological examination.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Conventional polypectomy

All colorectal polyps up to 10 mm found except for tiny hyperplastic polyps in the rectum and distal sigmoid colon are removed with electrocautery. Submucosal injection of some solution before the removal are not performed.

Group Type ACTIVE_COMPARATOR

Cold polypectomy

Intervention Type PROCEDURE

All colorectal polyps up to 10 mm found except for tiny hyperplastic polyps in the rectum and distal sigmoid colon are removed. The technique is cold resection of the polyp without tenting and then suction of the transected polyp into a trap followed by submission to histopathological evaluation.
