[Uni- or bilateral hepatoenterostomy in central bile duct occlusion?]

With the help of different microscopic and macroscopic techniques 100 livers have been investigated to find out whether there are primary and secondary intrahepatic communications between the bile ducts of the right and the left lobe. The results of these investigations are compared with eight case reports. To find the best surgical approach to extensive tumorous blockage of the hilus it is basically necessary to know the anatomical situation in detail.
