Abstract:
Perihilar cholangiocarcinoma or Klatskin tumors are a rare entity arising from the extrahepatic bile duct bifurcation. Considering the close anatomical relationship of the bile duct bifurcation with the portal vein bifurcation and hepatic arteries, surgical treatment is demanding. With an incidence of only 2-4 cases/100,000 population/year patients should be referred to a specialized center. The tumors are usually poorly differentiated adenocarcinomas growing diffusely along the duct and also the perineural sheath. Only radical surgery offers a curative option and currently surgical strategy usually consists of en bloc resection of the bile duct, extended liver resection and portal vein resection. Proximal and lateral safety margin R0 resections are technically very demanding procedures because of the local anatomy.
