1Department of Gastroenterology, Second Affiliated Hospital of Zhejiang University School of Medicine, Hangzhou, Zhejiang, China (mainland).
Abstract:
BACKGROUND 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.
