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.
