Massive post-polypectomy hemorrhage: Successful tulip-bundle technique with endoloop for hemostasis

Colonoscopic polypectomy is a common procedure for removing colonic polyps to prevent subsequent development of colon cancer. Hemorrhage is the most common complication following polypectomy, with a reported rate of 0.3% to 6.0%. The risk increases to 12.5% when the size of the polyp stalk exceeds 1 cm. The most commonly used endoscopic preventive techniques, such as injection therapy, prophylactic use of endoclip, or endoloop, were found to decrease the rate of post-polypectomy hemorrhage, and repeated use of these techniques is useful for controlling bleeding. Here, we reported a case of a 65-year-old man with refractory post-polypectomy hemorrhage for a 2-cm adenomatous polyp. Application of an endoloop using the tulip-bundle technique achieved successful hemostasis. To our knowledge, this is the first report of this technique being used to treat refractory acute post-polypectomy hemorrhage.
