系统分析腹腔镜胃底折叠术及抗反流手术治疗胃食管反流病（GERD）的研究现状与发展趋势。

检索PubMed数据库2014年1月至2024年9月相关文献，纳入809篇研究论文与综述，利用R语言bibliometrix软件包进行文献计量分析，涵盖发文趋势、期刊分布、作者贡献、国家合作、关键词共现及主题演化等维度。采用时间分层分析法，按发表年份计算篇均被引频次（CPP）和标准化引文影响力指数（NCLI），以校正发表时间对引文累积的影响。

该领域年均发文约73篇，近五年活跃度显著提升。主要发文期刊集中于外科与微创手术领域，以《Journal of Laparoendoscopic and Advanced Surgical Techniques》载文量最高（40篇）。作者生产力符合洛特卡定律，高产作者集中于少数研究者，以Omura Nobuo和Yano Fumiaki为代表。国家分析显示，美国在发文总量（356篇）、总被引频次（401次）及国际合作方面均领先；中国发文量排名第三（158篇），总被引频次位居第二（229次）。经时间分层分析校正后，中国篇均被引频次（1.45次/篇）仍显著高于全球平均水平（1.28次/篇），标准化引文影响力指数（NCLI=1.13）表明其学术质量获得国际认可，但与美国（CPP=3.12, NCLI=1.89）相比仍有差距。关键词分析表明"fundoplication"、"Nissen fundoplication"及"GERD"为核心主题，而"bariatric surgery"与"obesity"为新兴利基方向。共被引网络显示Stefanidis（2010）与Galmiche（2011）的文献具有重要知识奠基作用。

近十年来腹腔镜抗反流手术治疗GERD的研究持续发展，已形成集中化的学术格局，美国占据主导地位，中国研究在标准化指标下显示出稳健的学术影响力。未来应进一步关注个体化治疗、机器人辅助手术、GERD与代谢疾病共病管理，加强国际合作以提升引文影响力，并推动领域创新。

To systematically analyze the research status and development trends in the field of laparoscopic fundoplication and anti-reflux surgery in the treatment of gastroesophageal reflux disease (GERD).

The PubMed database was searched for relevant literature from January 2014 to September 2024, and 809 research papers and reviews were included. The R language bibliometrix software package was used for bibliometric analysis, covering publication trends, journal distribution, author contributions, national cooperation, keyword co-occurrence, and topic evolution. The time stratified analysis method is used to calculate the citations per paper (CPP) and the normalized citation impact index (NCLI) according to the year of publication to correct the impact of publication time on citation accumulation.

This field publishes an average of about 73 articles per year, and its activity has increased significantly in the past five years. The main journals publishing articles focus on the field of surgery and minimally invasive surgery, with the "Journal of Laparoendoscopic & Advanced Surgical Techniques" having the highest number of articles (40 articles). Author productivity is in line with Lotka’s law. Highly productive authors are concentrated in a small number of researchers, represented by Omura Nobuo and Yano Fumiaki. Country analysis shows that the United States leads in terms of total number of articles published (356), total number of citations (401 times), and international cooperation; China ranks third in number of articles published (158) and second in total number of citations (229 times). After correction by time-stratified analysis, China’s average citation frequency (1.45 times/article) is still significantly higher than the global average (1.28 times/article). The standardized citation impact index (NCLI=1.13) shows that its academic quality is internationally recognized, but there is still a gap compared with the United States (CPP=3.12, NCLI=1.89). Keyword analysis shows that "fundoplication" , "Nissen fundoplication" and "GERD" are core topics, while "bariatric surgery" and "obesity" are emerging niche directions. The co-citation network shows that the documents of Stefanidis (2010) and Galmiche (2011) play an important role in laying foundation for knowledge.

Research on laparoscopic anti-reflux surgery for the treatment of GERD has continued to develop in the past decade and has formed a centralized academic landscape. The United States occupies a dominant position, and Chinese research shows robust academic influence under standardized indicators. In the future, further attention should be paid to personalized treatment, robot-assisted surgery, GERD and metabolic disease comorbidity management, and international cooperation should be strengthened to increase citation influence and promote innovation in the field.
