A case series of choledochal cyst with pancreatic divisum: A rare association.

Choledochal cysts (CC) are congenital cystic dilations of the biliary tree usually associated with abnormal pancreaticobiliary ductal junction (APBDJ), but its association with pancreatic divisum has been rarely described. We encountered four cases of CC associated with pancreatic divisum (PD). Three had Type 3 PD and one had Type 1 PD. Two cases presented with pancreatic complications, with one case requiring preoperative minor papilla sphincterotomy for recurrent pancreatitis. The association of CC with PD is infrequent, and the variable presentation alters management strategy. PD may be one of the factors responsible for complications associated with CC.
