case_images:  Surgical exploration and cholangiography was performed at 12 weeks and showed cystic dilatation confined to the right-hepatic duct with an entirely normal left-hepatic duct draped around and with a low insertion of a cystic duct into a normal-looking common bile duct (CBD; Fig. 1A ).  Following cholecystectomy, the cyst was detached from the CBD and the transected proximal part with its draining segmental ducts anastomosed to a Roux's loop ( Fig. 1B ).
