Abstract
Cholecystocolonic fistula is an uncommon potential complication of cholecystitis found intraoperatively in 0.06–0.14 % of patients undergoing cholecystectomy and 0.1–0.5 % of autopsy series. Although cholecystocolonic fistula is the second most common cholecystoenteric fistula, second only to cholecystoduodenal fistula, it is diagnosed preoperatively in only 7.9 % of patients. Failure to preoperatively diagnose cholecystocolonic fistula places surgeons in precarious positions, as they may be forced to convert a seemingly routine cholecystectomy to a more sophisticated procedure coupled with adhesiolysis, colonic suturing, or colonic resection. We report a young patient who presented to the emergency department with complaints indicative of acute cholecystitis; however, preoperative ultrasound was suggestive of a cholecystoenteric fistula. Computed tomography and pathology were pathognomonic with clear visualization of the cholecystocolonic fistulous tract.
