Rare Case of a Combined Cholecystocolonic and Cholecystoduodenal Fistula Presenting With Pneumobilia.

Background: Cholecystoenteric fistulae are rare complications of gallstone disease, with a reported incidence of 0.5% to 0.9% of cholecystectomies. Cholecystoduodenal is the most common fistula followed by cholecystocolonic fistulae. Summary: We report a case of pneumobilia resulting from a combined cholecystoduodenal and cholecystocolonic fistulae treated with a laparoscopic subtotal cholecystectomy and open repair of the enteric fistulae. Conclusion: Combined cholecystoduodenal and cholecystocolonic fistulae are an extremely rare complication of gallstone disease, and meticulous preoperative planning and operative dexterity are needed to safely manage these unusual fistulae.
