Abstract
|
|
|
|
Among complications of choledochal cysts, malignant transformation is most concerning and management of choledochal cyst now includes complete cyst excision, whenever possible. In cases of choledochal cyst associated with pancreaticobiliary maljunction like our case, cholecystectomy along with the resection of dilatated bile duct and the biliary diversion are generally performed. However, incomplete cyst excision can result in malignant transformation within the remnant cyst. We present the case of cholangiocarcinoma arising from remnant intrapancreatic cyst 15 years after choledochal cyst excision in a patient with Todani type 1 choledochal cyst associated with pancreaticobiliary maljunction. We learn from the case that a careful long-term follow-up is needed in patients with choledochal cysts if residual cyst is remained after excision.
