Internal biliary fistula is a rare but well-known complication of cholelithiasis. It is a notoriously challenging entity to diagnose and manage. Gallstones are often the causative factor in the formation of a cholecystoenteric fistula, with the most common internal biliary fistula being a cholecystoduodenal fistula followed by a cholecystocolonic fistula. Rarely, do these fistulae exist simultaneously. Here, we present an uncommon case of cholecysto-duodenocolonic fistula.
Keywords: cholecysto-duodenocolonic fistula; cholecystoenteric fistula; cholelithiasis; internal biliary fistula.
