A 70-year-old man visited our hospital with vomiting and hematemesis. Abdominal CT scan showed common bile duct stone and enlarged gallbladder contained high density fluid and air. After admission, contrast enhanced CT scan showed cholecystoduodenal and cholecystocolonic fistula. Esophagogastroduodenoscopy and colonoscopy revealed fistulas in the duodenum and transverse colon near the hepatic flexure. Fistulography showed gallbladder. We performed endoscopic closure of the cholecystocolonic fistula using an Over the Scope Clip (OTSC) system. After closure the patient developed cholangitis, endoscopic retrograde cholangiopancreatography and removal of stones was performed. Cholecystoduodenal fistula reduced the size gradually, and cholecystocolonic fistula was closed completely.
