Classically, abdominal radiography reveals a triad of features:
- gas in the biliary tree:
- 40% of cases
- a gallstone in the intestine:
- often at the ileo-caecal junction
- small bowel obstruction
When the clinical picture is unclear, an upper gastrointestinal series will reveal the cholecystoenteric fistula and verify the intestinal obstruction.
