Comparison of Prophylactic Clip and Detachable Snare

Comparison of Clip and Detachable Snare in Preventing Postpolypectomy Bleeding for Pedunculated Colonic Polyps: a Prospective, Randomized Study

Although endoscopic colonic polypectomy has been an established procedure for two decades, the risk of bleeding is still higher after resecting of pedunculated polyps, because of the presence of a large artery in the stalk. Several preventive methods such as detachable snare and adrenaline injection have been proposed in the management of postpolypectomy bleeding in large colonic polyps. For prophylactic clip, there was no prospective randomized study assessing the efficacy in the prevention of postpolypectomy bleeding for the large pedunculated polyps. So we designed a prospective, randomized study to compares the efficacy of application of prophylactic clip and detachable snare in the prevention of postpolypectomy bleeding in large polyps. Application of prophylactic clip will be as effective and safe method as detachable snare in the prevention of postpolypectomy bleeding for the large pedunculated colonic polyps.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Prophylactic clip
Procedure: Prophylactic clip
Before conventional snare polypectomy, hemoclips were applied on the base of stalk in the prophylactic clip group
Active Comparator: Detachable snare
Procedure: Detachable snare
In the detachable snare group, detachable snare was positioned at the base of stalk and followed by conventional snare polypectomy

Primary Outcome Measures

Outcome Measure
Time Frame
Postpolypectomy bleeding
Time Frame: Immediate (bleeding occurring immediately after polypectomy and lasting for 30 s or more) and delayed bleeding complications were assessed. Delayed bleeding was subdivide into early (<24 h) and late (>24 h-30 days).
