A variant of an accessory common bile duct

While variations of the common bile duct are relatively common, true duplic ation of the common bile duct is very rare. Such deviation from normal anat omy, if unrecognized, may cause problems during surgical intervention. Here we present a case of a unique variant of an accessary bile duct which aris es from the confluence of the right and left hepatic ducts and runs down to join the pancreatic duct to form a long, common channel before opening int o the papilla with the main duct.
