Surgical series use the type to plan resection: one (Govil and colleagues, HPB 2016) notes that right-sided liver resections are preferred for type IIIb tumours and that type IV tumours, which involve the confluence, became more often resectable with left-sided resection and arterial reconstruction. It describes anatomy for surgery and is not a stage.","asOf":"2026-11-04","links":[{"label":"NCI Thesaurus C134736, Bismuth-Corlette Hilar Cholangiocarcinoma Classification","url":"https://evsexplore.semantics.cancer.gov/evsexplore/concept/ncit/C134736"},{"label":"Govil et al., Liver resection for perihilar cholangiocarcinoma: why left is sometimes right (HPB 2016)","url":"https://doi.org/10.1016/j.hpb.2016.05.002"}],"tags":[],"related":["biliary-anatomy-subtypes","intrahepatic-cholangiocarcinoma-staging"],"cancers":["extrahepatic-cholangiocarcinoma","cholangiocarcinoma"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"category":"Clinical"},"route":"/terms/bismuth-corlette/","neighbours":{"term":[{"id":"staging-systems","kind":"term","name":"Disease-specific staging and risk systems (FIGO, Ann Arbor, IPI, R-ISS, ELN, IMDC)","route":"/terms/staging-systems/"},{"id":"intrahepatic-cholangiocarcinoma-staging","kind":"term","name":"Intrahepatic bile duct cancer staging (AJCC chapter 23)","route":"/terms/intrahepatic-cholangiocarcinoma-staging/"},{"id":"biliary-anatomy-subtypes","kind":"term","name":"Intrahepatic, perihilar, distal and gallbladder cancer","route":"/terms/biliary-anatomy-subtypes/"}],"cancer":[{"id":"cholangiocarcinoma","kind":"cancer","name":"Biliary tract cancer (cholangiocarcinoma)","route":"/cancers/cholangiocarcinoma/"},{"id":"extrahepatic-cholangiocarcinoma","kind":"cancer","name":"Extrahepatic cholangiocarcinoma (perihilar and distal)","route":"/cancers/extrahepatic-cholangiocarcinoma/"}]}}
