“STEP CLIPPING” METHOD: A NOVEL TECHNIQUE OF DETECTING THE RESPONSIBLE LESION FOR COLONIC DIVERTICULAR BLEEDING (WITH A VIDEO)

Abstract

In colonic diverticular bleeding cases, the detection rate of the responsible lesion by colonoscopy remains unsatisfactory even with the supportive information of extravasation depicted by contrast-enhanced computed tomography (CECT). This is because colonoscopy does not provide as precise positional information as computed tomography (CT). The “step clipping” method could overcome this limitation by making artificial signposts that can be commonly recognized on both CT and colonoscopy. Colonoscopy with positional navigation through this method could boost the detectability of the responsible lesion and shorten the endoscopic searching time for the culprit lesion.
