CHOLECYSTOCOLIC FISTULA : A RARE ENTITY

Abstract Cholecystocolic fistula is the most infrequent biliary enteric fistula, causing significant morbidity and representing a diagnostic challenge. Modern diagnostic tools, like crossectional imaging is required preoperatively. These fistulae are treated mostly by open as well as laparoscopic surgery. We report an imaging review of Cholecystocholic fistula. Patient present with abdominal pain & bleeding per rectum. Previous ultrasound was done few months ago with cholelithiasis, because of acute abdomen we directly precede with Computed Tomography abdomen with I/V contrast. The case was finally diagnosed on the CT scan abdomen as Cholecystocolic fistula in the background of Acute cholecystitis. Computed Tomography is the best tool not only to diagnose but findings the complication associated with Cholecysto-Colic /Enteric Fistula.
