Adult Choledochal Cyst

The prognosis for patients with malignancy complicating choledochal cyst remains poor despite aggressive radical surgery such as Whipple's operation or additional hepatectomy. Malignancy should be suspected in older and male patients who present with jaundice or impaired liver function tests. Total cyst excision and hepaticojejunostomy is an effective and safe treatment for patients with the common type I choledochal cyst in order to reduce the chance of subsequent development of malignancy.
