[A 41-year-old woman with recurrent cholangitis after bile duct operation 17 years earlier. A case report].

The case of an 41 year old female is reported, who underwent surgical correction of a congenital cyst of the common bile duct 17 years ago. Because of repeated pain attacks in the right upper quadrant in connection with fever and serochemical signs of cholestasis the patient was admitted to our unit. The exploration with ERCP and CT now showed a common channel in combination with a congenital cyst of the common bile duct. The risk of the anomalous pancreaticobiliary junction upon either the biliary tract or the pancreatic duct will be discussed, also the fact of an higher incidence of malignant tumors of the biliary system. The therapeutic procedures will be discussed.
