Colonic diverticular bleeding is the most common type of gastrointestinal bleeding. We report a case of an 82-year-old man with a chief complaint of melena. Enhanced computed tomography showed multiple diverticula, and water-assisted colonoscopy could not help identify the diverticulum responsible for bleeding. We injected VISCOCLEAR, a novel gel formulation, into the digestive tract endoscopically and successfully localized the bleeding point. Moreover, the use of VISCOCLEAR secured a clear visual field with reduced glare, as seen in the digital endoscopic image. Subsequently, we performed hemostatic clipping. The course after the endoscopic treatment was unremarkable. In this case, we could identify the exposed bleeding vessels in the diverticulum using VISCOCLEAR and perform hemostatic clipping. We intend to evaluate the effectiveness of VISCOCLEAR further by analyzing a series of cases.
