title: Type IV congenital choledochal cyst concurrent with acute pancreatitis: a case report.
abstract: BACKGROUND
  Congenital choledochal cyst is a rare kind of bile duct deformity, resulting from cystic or shuttle-like dilation of part of the choledochal duct congenitally. We present a 20-year-old girl with a congenital choledochal cyst complicated by acute pancreatitis.
  
  
  METHODS
  The clinical data of the woman with a congenital choledochal cyst concurrent with acute pancreatitis were retrospectively analyzed.
  
  
  RESULTS
  The congenital choledochal cyst of the woman was type IV complicated by acute pancreatitis.
  
  
  CONCLUSIONS
  The diagnosis of congenital choledochal cyst mainly depends on CT, MRCP, and ERCP. Total excision of the choledochal cyst with Roux-en-Y hepaticojejunostomy is recommended as the treatment. For patients with type V cysts with frequently recurrent cholangitis resulting biliary liver cirrhosis, liver transplantation should be considered.
