Abstract
Introduction: Cholangiocarcinoma may grow out of the intrahepatic bile ducts of the bifurcation and common hepatiku and distal hepatocholedochu. Hilar cholangiocarcinoma tends to increase to around infiltrativnímu hepatocholedochu while also increasing the longitudinal axis of the bile duct.
Extent of infiltration into the environment determines the need for vascular resection and urging limits on disability in the longitudinal axis of the bile duct is essential to indicate the type of liver resection. Preoperative diagnosis and staging is extremely important for a surgeon.
Conclusion: The distinction between Klatskin tumor and lesions simulating Klatskin tumor is difficult, even impossible. Up to 15% of patients indicated for resection of malignancy was confirmed in the resection.
Both types require the involvement of hilar bile duct resection and the importance of diagnosis lies in the fact that Klatskin tumor requires extensive resections often comprise a large part of liver parenchyma.
