Herein, we present a fully robotic right hepatectomy with formal portal lymphadenectomy in a 76-year-old woman with a 5.5-cm centrally located intrahepatic cholangiocarcinoma with underlying hepatic steatosis. Preoperative evaluation included cross-sectional imaging and volumetric assessment to ensure adequate future liver remnant, consistent with contemporary recommendations for minimally invasive major hepatectomy. The procedure was performed using a structured, stepwise approach emphasizing early hilar dissection, inflow-first control, parenchymal transection under low central venous pressure &lt;5mmHg, and systematic portal lymphadenectomy. The operation was completed in 6 hours with an estimated blood loss of 150\u00a0mL without Pringle maneuver. The patient was discharged on postoperative day 5 without perioperative complications. Final pathology demonstrated a poorly differentiated intrahepatic cholangiocarcinoma with negative margins (R0) and no lymph node metastases (0\/6), consistent with current staging recommendations. At one year, the patient remains disease free. Beyond technical feasibility, this report illustrates a reproducible operative framework informed by cumulative institutional experience, including prior analyses of robotic hepatectomy outcomes, learning-curve progression, and preoperative difficulty stratification. This approach may support incremental expansion of robotic indications for selected centrally located tumors within established hepatobiliary programs.<\/jats:p>","DOI":"10.1177\/00031348261465401","type":"journal-article","created":{"date-parts":[[2026,6,27]],"date-time":"2026-06-27T07:14:07Z","timestamp":1782544447000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Robotic Resection of Right Perihilar Intrahepatic Cholangiocarcinoma: Practical Technique of Major Hepatic Resection for Biliary Tract Cancer"],"prefix":"10.1177","author":[{"given":"Shivanshu","family":"Kumar","sequence":"first","affiliation":[{"name":"AdventHealth Tampa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Christodoulou","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of South Florida Morsani College of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7259-1552","authenticated-orcid":false,"given":"Iswanto","family":"Sucandy","sequence":"additional","affiliation":[{"name":"AdventHealth Tampa"},{"name":"Dr. Soetomo General Academic Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,27]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11605-017-3426-x"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12893-021-01363-4"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00464-025-11900-4"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.3390\/cancers14041046"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.21037\/hbsn-22-555"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.gassur.2024.05.030"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.gassur.2024.04.012"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.gassur.2024.02.022"}],"container-title":["The American Surgeon\u2122"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/00031348261465401","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/00031348261465401","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/00031348261465401","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,11,6]],"date-time":"2026-11-06T14:19:53Z","timestamp":1793974793000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/00031348261465401"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,27]]},"references-count":8,"alternative-id":["10.1177\/00031348261465401"],"URL":"https:\/\/doi.org\/10.1177\/00031348261465401","relation":{},"ISSN":["0003-1348","1555-9823"],"issn-type":[{"value":"0003-1348","type":"print"},{"value":"1555-9823","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6,27]]},"article-number":"00031348261465401"}}
