Diagnostic-therapeutic management of bile duct cancer

Figure 1 Bismuth-Corlette classification of pCCA (modified from Guidi et al[109]). Type I: The tumor is located below the confluence of the left and right hepatic ducts and involves the common hepatic duct. Type II: The tumor involves the bifurcation of the common hepatic duct but does not affect the left or right hepatic ducts. Type III: The tumor occludes the common hepatic duct and the right hepatic duct (IIIa) or left hepatic duct (IIIb). Type IV: The tumor involves both the right and the left hepatic ducts or there is bilateral involvement or involvement of multiple intrahepatic segments.
