Abstract
A 74-year-old woman visited a local physician because of diarrhea and loss of appetite. She was referred to our hospital after the laboratory data indicated elevation of the serum bilirubin level. Abdominal CT showed pneumobilia. ERCP showed the formation of a fistula between the shrunken gallbladder and the hepatic flexure. Colonoscopy showed a fistula on the right side of the transverse colon, and fistulography enabled visualization of the gallbladder and the common bile duct. We diagnosed this patient as a case of cholecystocolonic fistula and performed an operation via the laparoscopic approach. At operation, the fistula was resected using an endoscopic linear stapler and cholecystectomy was performed. The postoperative course was uneventful and the patient was discharged on postoperative day 11. Laparoscopic surgery is feasible for the treatment of cholecystocolonic fistulas.
