title: Cholecystocolonic fistula prevents upper intestinal obstruction by a large gallstone after perforation into the duodenum.
abstract: BACKGROUND
  Bilioenteric fistulas are rare complications of cholecystolithiasis that are associated with high morbidity and mortality and mainly appear in elderly patients.
  
  
  METHODS
  This is the report of a patient suffering from cholecystoduodenal fistula with additional cholecystocolonic fistula.
  
  
  CONCLUSIONS
  This cholecystocolonic fistula provoked a short bowel syndrome with symptomatic diarrhea and prevented an upper gastrointestinal ileus caused by the large perforated gallstone into the duodenum. This interesting constellation has not been described in literature yet.
