Bismuth-Corlette classification of Klatskin tumors: which type is NOT resectable with curative intent using standard hepatic resection alone?
- A Type I
- B Type IV ✓
- C Type II
- D Type IIIa
Explanation
Bismuth-Corlette Type IV hilar cholangiocarcinoma involves the second-order biliary radicles of both right and left hepatic ducts, making curative-intent resection with negative margins essentially impossible with standard surgery. Types I–III can be addressed with bile duct resection ± hepatectomy: Type I (common hepatic duct, below confluence), Type II (confluence), Type IIIa (right hepatic duct to second order), Type IIIb (left side). Type IV bilateral second-order involvement requires either liver transplantation (Mayo protocol for highly selected patients) or palliative drainage.
