Asymptomatic Cholecystocolic Fistula Diagnosed Accurately before Surgery / 대한췌담도학회지

Cholecystocolic fistula (CCF) is a rare and late complication of gallbladder disease. The cause of CCF is known to be peptic ulcer, gallbladder disease, malignant tumor, trauma, and postoperative complications. The proper treatment method is to perform cholecystectomy and to identify and alleviate the CCF. However, cholecystectomy is not always possible owing to technical difficulties and disease severity. CCF is difficult to diagnose preoperatively, and CCF operation without an accurate preoperative diagnosis can lead to a more complicated surgery and cause surgeons to face more difficult situations or to endanger patients' lives. We report a case of asymptomatic CCF successfully treated with laparoscopic surgery after accurate diagnosis before surgery.

Cholecystocolic Fistula: A Diagnostic Dilemma.

Cholecystocolic fistula is a rare biliary-enteric fistula with a variable clinical presentation. Despite modern diagnostic tools a high degree of suspicion is required to diagnose it preoperatively1,2. Biliary-enteric fistulae have been found in 0.9% of patients undergoing biliary tract surgery. The most common site of communication of the fistula is a cholecystoduodenal (70%), followed by cholecystocolic (10-20%), and the least common is the cholecystogastric fistula accounting for the remainder of the cases. Even a case of choledochocolonic fistula through a cystic duct remnant has been reported3. These fistulae are treated by open as well as laparoscopic surgery with no difference in intraoperative and postoperative complications. We report a case of obstructive jaundice, which was relieved by itself and was investigated with abdominal ultrasonography and routine investigations but none of these gave us any clue to the presence of the fistula which was discovered incidentally during an open surgery and was appropriately treated.
