The prognosis after excision of a choledochal cyst is usually excellent, but it is influenced by several factors, including patient's age, cyst type, histologic features, and site. [20] Moreover, patients need lifelong follow-up because of the increased risk of cholangiocarcinoma and gallbladder carcinoma, even after complete excision of the cyst. [21] In adults, there appears to be a 6-30% risk of malignancy associated with choledochal cyst. [20]
