Stalk Injection and Prophylactic Clipping of Pedunculated Polyps Increase Delayed Bleeding

In this Japanese study from 5 institutions, 1147 pedunculated (stalk length of ≥5 mm) colorectal polyps were evaluated for predictors of immediate bleeding after being removed by Endo Cut (Erbe Elektromedizin GmbH, Tuebingen, Germany) or forced coagulation current. Overall, immediate bleeding occurred in 8.5% of polypectomies, and the all-important delayed bleeding occurred in 2% of polypectomies. For polyps ≥15 mm in size, Endoloop (Ethicon, Somerville, NJ) reduced the risk of immediate bleeding by 83% but did not prevent delayed bleeding. Prophylactic clipping before polypectomy (odds ratio [OR], 4.2) and injecting the stalk (OR, 4.0) actually increased the risk of delayed bleeding. Placement of clips on the resection site after polyp removal was not associated with a reduced risk of delayed bleeding.
