Endoscopic detachable snare ligation method for colonic diverticular hemorrhage

Abstract

Colonic diverticular hemorrhage is the most common cause of lower intestinal bleeding. Endoscopic clipping and endoscopic band ligation (EBL) are both reported treatment methods. However, the re-bleeding rate after endoscopic clipping is considerably high; EBL is often required to re-insert the colonoscope to attach the ligation device on the scope tip. We developed a novel endoscopic hemostatic method, detachable snare ligation, to solve these issues, and studied its safety and efficacy. Six patients with bleeding colonic diverticulum were treated with detachable snare ligation from November 2013 to May 2014. Sustained hemostasis was achieved in five patients (83.3%) . No complications were noted in any patient. Hemostasis with detachable snare ligation is a safe and effective treatment method for hemorrhage from the colonic diverticulum.
