title: [Cholecystoduodenal fistula with subsequent gallstone ileus: case report of an unusual course].
abstract: Gallstone ileus is a rare complication of cholecystolithiasis with a high mortality because of the advanced age of the patients and the often delayed diagnosis. Signs of a cholecystoduodenal fistula are often absent in conventional ultrasonic and radiological methods. Treatment options are: 1. Enterolithotomy, 2. One stage procedure or 3. Two stage procedure consisting of enterolithotomy and the surgery of the biliary tract. In the case of our patient we performed a conventional cholecystectomy and the closure of the cholecystoduodenal fistula, which was found accidentally. When the gallstone ileus appeared 6 days later the enterolithotomy was performed. Thus in case of accidentally found cholecystoduodenal fistula an exploration of the abdominal cavity and the small intestine to find the gallstone should be performed on principle. Gallstones with a diameter of more than 2-3 cm should be removed by enterolithotomy to prevent the gallstone ileus.
