Cholecystocolonic fistula presenting as a lower gastrointestinal bleeding: Preoperative work-up, treatment options, and literature review

Abstract

Cholecystocolonic fistulae are the second most common choloenteric fistulae, yet only a small percentage are diagnosed preoperatively. This lack of preoperative recognition often leads to intraoperative discovery, leaving little opportunity for preoperative planning. Herein, we present the case of a 59-year-old male who presented with a cholecystocolonic fistula, manifested by lower gastrointestinal bleeding. Recognition of the fistula allowed for medical optimization and preoperative planning. There is currently a shortage of data on the ideal management of cholecystocolonic fistulae. We review the literature on cholecystocolonic fistulae and discuss the alternatives and controversies to the optimal management.
