Objective To conduct a bibliometric analysis of robot-assisted hepatectomy(RAH)related publications,visualize publication trends,and identify current research hotspots and emerging developments.Methods SCIE-indexed publications on Web of Science were retrieved using the keyword"robot-assisted hep-atectomy",covering the period from January 1,2000 to December31,2025.Bibliometric methods were applied to analyze publication years,countries/regions,institutions,journals,authors,highly cited publica-tions,collaboration networks,and keyword co-occurrence networks.Results A total of 304 publications were included.Annual RAH-related publications had increased steadily since 2008,entering a rapid growth phase(average annual growth rate:26.6%)between2019 and2025,with a historical peak of 58 publications in2025.The United States was the top contributor(103 articles,33.88%),followed by China(82 articles,26.97%)and Italy(80 articles,26.32%),representing the primary contributors to global RAH research.Among institutions,AdventHealth Tampa(USA)led with 20 publications,followed by Chinese PLA General Hospital(China)and University of Modena and Reggio Emilia(Italy),each with 14 publications.The most prolific journal was Surgical Endoscopy and Other Interventional Techniques(43 articles),followed by American Surgeon(21 articles).The collaboration network analysis revealed AdventHealth Tampa exhibited the high-est degree of external collaboration,followed by Chinese PLA General Hospital and University of Modena and Reggio Emilia.Scholarly influence analysis indicated that Sucandy I(39 publications,342 citations)was the most prolific author,and together with Coratti A(587 citations)and Choi GH(365 citations)ranking as the top three most highly cited scholars.Top cited journals included Surgical Endoscopy and Other Intervention-al Techniques(893 citations),HBP(399 citations)and Annals of Surgical Oncology(281 citations).Keyword co-occurrence analysis identified"laparoscopic hepatectomy","alveolar echinococcosis"and"interna-tional study group"as high-frequency terms reflecting current hotspots.Keywords such as"cancer"and"laparoscopic hepatectomy"indicated emerging trends.Conclusion Global RAH research activity is ex-panding rapidly,with the research output gap between China and western countries narrowing steadily.Current focuses and emerging trends primarily center on cancer,alveolar echinococcosis,and laparo-scopic hepatectomy.
