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% of patients and extended LND in 52.9%. Clavien-Dindo grade ≥ III complications occurred in 69.8% with LND ≥ 6 compared with 46.4% with LND1-5 and 41.8% with no LND (p < 0.001), with longer ICU and hospital stays and more septic and pulmonary events. On multivariable analysis, LND ≥ 6 was not an independent predictor of morbidity in the overall cohort, but in the subgroup of major resections (OR 2.79, 95% CI 1.121-6.955, p = 0.027). LND extent had no independent impact on OS or RFS.Extended LND was associated with a higher rate of postoperative complications and was an independent risk factor in patients undergoing major hepatectomy. However, no clear survival benefit was observed. These findings may suggest that the role of LND in BTC may be primarily diagnostic and that more selective, biology-driven approaches should be considered. Prospective studies are needed for validation. 000309938 536__ $$0G:(DE-HGF)POF4-899$$a899 - ohne Topic (POF4-899)$$cPOF4-899$$fPOF IV$$x0 000309938 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo02.dkfz.de 000309938 650_7 $$2Other$$aBiliary tract cancer 000309938 650_7 $$2Other$$aLymphadenectomy 000309938 650_7 $$2Other$$aPostoperative morbidity 000309938 650_7 $$2Other$$aRecurrence-free survival 000309938 650_7 $$2Other$$aStaging accuracy 000309938 7001_ $$aNikbakhsh, Rajan$$b1 000309938 7001_ $$aBendig, Sarah$$b2 000309938 7001_ $$0P:(DE-HGF)0$$aRadulova-Mauersberger, Olga$$b3 000309938 7001_ $$0P:(DE-HGF)0$$aSchweipert, Johannes$$b4 000309938 7001_ $$0P:(DE-HGF)0$$aWeitz, Jürgen$$b5 000309938 7001_ $$0P:(DE-HGF)0$$aRiediger, Carina$$b6 000309938 773__ $$0PERI:(DE-600)2074021-9$$a10.1245/s10434-026-19192-1$$pnn$$tAnnals of surgical oncology$$vnn$$x1068-9265$$y2026 000309938 909CO $$ooai:inrepo02.dkfz.de:309938$$pVDB 000309938 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b0$$kDKFZ 000309938 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b3$$kDKFZ 000309938 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b4$$kDKFZ 000309938 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b5$$kDKFZ 000309938 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b6$$kDKFZ 000309938 9131_ $$0G:(DE-HGF)POF4-899$$1G:(DE-HGF)POF4-890$$2G:(DE-HGF)POF4-800$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bProgrammungebundene Forschung$$lohne Programm$$vohne Topic$$x0 000309938 9141_ $$y2026 000309938 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2024-12-17$$wger 000309938 915__ $$0StatID:(DE-HGF)3002$$2StatID$$aDEAL Springer$$d2024-12-17$$wger 000309938 915__ $$0StatID:(DE-HGF)3002$$2StatID$$aDEAL Springer$$d2024-12-17$$wger 000309938 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bANN SURG ONCOL : 2022$$d2024-12-17 000309938 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2024-12-17 000309938 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2024-12-17 000309938 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2024-12-17 000309938 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2024-12-17 000309938 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine$$d2024-12-17 000309938 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2024-12-17 000309938 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2024-12-17 000309938 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2024-12-17 000309938 9201_ $$0I:(DE-He78)DD04-20160331$$kDD04$$lKoordinierungsstelle NCT Dresden$$x0 000309938 980__ $$ajournal 000309938 980__ $$aVDB 000309938 980__ $$aI:(DE-He78)DD04-20160331 000309938 980__ $$aUNRESTRICTED
