The morphology of the biliary extrahepatic ducts of 32 Landrace pigs were studied through the dissection of anatomical specimens composed by liver and duodenum. The pigs were separated in two groups of 16 animals each. The first group was initially submited to a laparoscopic cholecystectomy, than observed during a brief postoperative period, and eventually killed for attainment of the anatomical specimens; while the second group was destined to slaughter and the anatomical specimens obtained after their death. The study of the anatomical specimens was performed by the dissection of the bilary extrahepatic ducts when they were painted with gouache and then radiologically studied using barium injection. The data was analysed employing the FISHER’S test. The ductus choledochus was composed by the junction of the ductus cysticus and the ductus hepaticus in 84,3% of the cases, and the ductus hepaticus was composed by the junction of the ductus principalis sinister and ductus principalis dexter also in 84,3% of the cases. If was concluded that there was no significative difference related to the anatomical configuration of the biliary extrahepatic ducts in both groups.
