The enterobiliary fistulas are mostly spontaneous and are caused by biliary disease associated with calculi. Review of many series shows that the most common variety of enterobiliary fistulas is a cholecystoduodenal fistula followed by cholecystocolic, cholecystogastric and choledochoduodenal fistula in that order. But very few cases of choledochocolonic fistulae have been reported. We report a case of choledocholithiasis combined with the absence of gallbladder leading to a choledochocolonic fistula, which was confirmed by endoscopic retrograde cholangiography and abdominal exploration in a 63- year-old male patient with complaint of right upper abdominal pain.
