Abstract

It is well known that Choledochal Cyst(CC) is congenital dilatation of the biliary tree associated with Anomalous Pancreatico Biliary Ductal Union(APBDU), and complete excision is gold standard treatment. [1] CC is one of the risk factors of biliary tract malignancy and complete resection of CC is recommended for the treatment. Surgeons should be careful to avoid injury of the pancreatic duct when removing intrapancreatic portion. For this reason, some part of CC can remain in the intrapancreatic portion andlead to stone formation, recurrent pancreatitis, and cholangiocarcinoma in remnant intrapancreatic CC.
