The development of curative surgery for hilar cholangiocarcinoma is based on the precise knowledge of anatomy of the hepatic hilus and of the frequent anatomical variations that may be encountered. For these reasons it would be useful to point out some anatomical details, with particular regard to the anatomy of the hilar and caudate lobe area that are the crucial point of this surgery. Biliary ducts, arterial and portal vessels that are covered by connective tissue arising from the fusion of Glisson’s capsule, in the intrahepatic portion, and peritoneum of the hepatoduodenal ligament, in the extrahepatic portion, constitute the plate system. In this space several lymphatic vessels, nerves and a small vascular network are present (Fig. 1).
