Cholecystocolonic fistula.

The cholecystocolonic fistula is an atypical variant of biliary disease. When presenting with symptomatic disease, surgical treatment with cholecystectomy, fistula takedown and possible colonic resection are indicated, however the role of surgery in asymptomatic patients, especially those deemed higher risk is less clear. Herein we present a case of an incidentially discovered asymptomatic cholecystocolonic fistula in a higher risk surgical patient managed nonoperatively. The presentation and treatment options for this disease are discussed in relation to their application to this patient.
