[Spontaneous cholecystocolic fistula]

Cholecystoenteric fistula is a rare complication of biliary tract diseases. The symptoms are abdominal pain, fever, nausea, vomiting, flatulence, fat intolerance, diarrhoea and weight loss. The fistula may often be asymptomatic for a long time. We report a 76-year-old woman with a cholecystocolic fistula between the gallbladder and the right flexure of the colon. The symptoms were persistent right upper quadrant pain and diarrhoea. Barium enema demonstrated the fistula. The patient was treated with an open cholecystectomy and a resection of the fistula.
