While guidelines recommend retrieval of ≥ 6 lymph nodes to ensure accurate staging, evidence for a therapeutic survival benefit is limited.We retrospectively analyzed 253 consecutive resections for intrahepatic cholangiocarcinoma (iCCA), perihilar cholangiocarcinoma (pCCA), and gallbladder carcinoma (GBC) at a high‑volume hepatobiliary center from a prospectively maintained database (2013-2023). Patients were stratified into no (0 nodes), limited (1-5 nodes), and extended (≥ 6 nodes) LND. Postoperative morbidity, recurrence-free survival (RFS), and overall survival (OS) were assessed with uni- and multivariable models.LND was performed in 47 %K Biliary tract cancer (Other) %K Lymphadenectomy (Other) %K Postoperative morbidity (Other) %K Recurrence-free survival (Other) %K Staging accuracy (Other) %F PUB:(DE-HGF)16 %9 Journal Article %$ pmid:41699355 %R 10.1245/s10434-026-19192-1 %U https://inrepo02.dkfz.de/record/309938
