Pancreatitis associated with choledochal cyst and other anomalies in childhood.

Fifty-one children with anatomical anomalies of the pancreatic duct developed pancreatitis associated with either congenital dilatation of the bile duct (choledochal cyst; n = 48) or other rare causes (n = 3). Among those with choledochal cyst, 41 underwent primary surgical resection of the dilated bile duct, while five of the remaining seven patients receiving cystenterostomy underwent secondary resection of the cyst.
