Cholecystocolonic fistula in exacerbated chronic cholecystitis: A case report.

The cholecystocolonic fistula (CCF) is an atypical variant of biliary disease, and it is the second most common intestinal fistula after cholecystoduodenal fistula. Intraoperative diagnosis is frequent, which implies challenging surgical management, especially in patients, often aged, with comorbidities. The rarity of this condition, atypical and various presentation, diagnostic and management complexity, makes it a unique surgical entity. We report our experience of an 84-year-old man with a history of chronic cholecystitis who presented with nonspecific symptoms. The imaging tests aroused the suspicion of gallbladder-colic fistula in the preoperative diagnosis, facilitating the subsequent surgical treatment that confirmed the diagnosis.
