Cholecystocolic fistula from colonic diverticular disease with concomitant choledocholithiasis: A case report

Abstract

We present a 79 year-old female who consulted for abdominal pain. There was evidence of sigmoid diverticulitis with colonic obstruction and biliary-enteric fistula formation, on the imaging. The patient underwent a Hartmann’s Procedure, resection of cholecystocolic fistula, and intraoperative choledochoscopy with common bile duct stone extraction. The pathophysiology and management of cholecystocolic fistula are discussed.
