Due to the absence of specific symptoms and signs, cholecystocolic fistula is easy to miss as a diagnosis or misdiagnose.
CASE REPORT: We report a case of an older male patient who had cholecystocolic fistula which was misdiagnosed as colon cancer. The cholecystocolic fistula was incidentally discovered during surgery and was appropriately treated.
CONCLUSIONS: Cholecystocolic fistula is a rare complication of gallstone disease. Symptoms can be nonspecific. This case report demonstrates that despite modern diagnostic tools available, a high degree of suspicion is required to diagnose cholecystocolic fistula preoperatively. Open cholecystectomy and closure of fistula is the treatment of choice.
