title: [Klatskin tumors: rational diagnostics and staging].
abstract: Klatskin tumors continue to be a challenge for diagnostic assessment and staging due to their longitudinal tumor growth along the perihilar bile ducts. Therefore the rate of non-resectable tumors remains relatively stable despite modern imaging and endoscopic techniques. This article reviews the current diagnostic methods for preoperative staging and the significance for predicting resectability.
