背景与目的 腹腔镜肝切除术的可行性和优越性已得到充分肯定。近年来，国内学者已开展了许多复杂的腹腔镜肝脏手术，但仍然缺少对腹腔镜肝脏手术相关领域整体研究进展的探讨。本研究通过分析腹腔镜肝脏手术研究领域的发文情况、研究热点以及研究趋势，为该领域相关人员开展腹腔镜肝切除术的学术研究提供参考。方法 在Web of Science数据库中检索腹腔镜肝切除术相关的英文文献（论著或综述），发表日期限定为1991年1月1日—2021年12月31日。运用Excel软件对检索到的文献进行统计梳理，得到年度发文量、发文国家/地区、发文期刊、发文机构、发文作者等基本概况，运用VOSviewer进行可视化聚类分析，得出研究热点和发展趋势。结果 检索获得4 437篇文献，数据显示，日本为腹腔镜肝切除术领域中发文量最大国家（647篇），中国（617篇）和美国（523篇）分别位于第二、三。发文量最大的前3名作者分别是美国的Gayet Brice（70篇），韩国的Han Ho Seong（58篇）和日本的Wakabayashi Go（58篇）。腹腔镜肝切除术的研究热点集中于肿瘤患者的远期疗效、肝脏亚段的切除、机器人手术以及提升手术安全性等方面。结论 腹腔镜肝切除术因其创伤小、恢复快等优势，已被世界范围内广泛使用，中国研究者未来不仅需要关注该领域的前沿研究，还应积极开展多中心研究项目。
Background and Aims The feasibility and superiority of laparoscopic hepatectomy have been fully affirmed. In recent years, domestic scholars have carried out many complex laparoscopic hepatectomy, but there is still a lack of discussion on the overall research progress of laparoscopic hepatectomy. This study was conducted to analyze the publications, research hotspots and research trends in the field of laparoscopic liver surgery, and to provide reference for relevant personnel in this field to undertake the academic studies in laparoscopic liver resection.Methods The English literature on laparoscopic hepatectomy research (research article or review article), published from January 1, 1991 to December 31, 2021, was retrieved in the Web of Science database. The retrieved data were sorted by Excel software, and the basic profiles of annual number of publications, and the contributing countries/regions, journals, institutions and authors were obtained. Clustering analysis was visualized using the VOSviewer software, and then the maps of research hotspot and development trend were created.Results A total of 4 437 documents were returned after retrieval. The data showed that Japan was the leading country with the most publications (647 papers) in the field of laparoscopic hepatectomy, followed by China (617 papers) and the United States (523 papers). The top 3 productive authors of publications were Gayet Brice from the United States (70 papers), Han Ho Seong from the Republic of Korea (58 papers), and Wakabayashi Go from Japan (58 papers). The research hotspots in this field focused on the long-term efficacy of tumor patients, subsegmental resection of the liver, robotic surgery and improvement of surgical safety.Conclusion Laparoscopic hepatectomy has been widely used worldwide owing to its advantages of small trauma and rapid recovery. In the future, Chinese scholars should not only pay attentions to the research frontiers in this field, but also should actively carry out multi-center research projects.
