A 75-year-old woman with hepatitis C virus antibody-positive liver cirrhosis was admitted to our hospital with anal bleeding. Colonoscopy revealed red color-positive tortuous transverse colonic varices near the splenic flexure. Colonic varices were considered to be the most probable cause of bleeding, although the precise site could not be determined. Endoscopic injection sclerotherapy was performed for colonic varices. Endoscopic clipping was performed for bilateral sites of varices as an additional treatment. Four months after endoscopic treatments, colonoscopy revealed ulcer scars in the transverse colon and shrinkage of the varices.
