RESUMEN
Objective To explore the pathogenesis, pathomorphology, diagnosis and management of cholecystoduodenal fistula(CDF). Methods Clinical data of 11 cases of CDF admitted in our hospital in recent 17 years were analyzed retrospectively. Results All the patients were confirmed and treated by operation.Ten CDF were caused by cholecystitis and cholelithiasis,another one was caused by peptic ulcer.Only one case of CDF was diagnosed before operation. Nine patients were cured, and two patients died of severity infection of abdomen postoperatively. Conclusions Most CDF are caused by cholecystitis and cholelithiasis. X-ray film of abdomen,barium meal examination and endoscopic retrograde cholangiopancreatography(ERCP) are more useful for the diagnosis of CDF. The therapeutic principle of CDF is cholecystectomy,removing calculus, and repairing fistula with or without common bile duct exploration and/or bilioenterostomy.
