摘要
目的:总结中外消化内镜隧道技术(DETT)领域自2006年至今的发文现状及研究趋势。方法:在Web of Science和中国知网数据库中检索2006年1月1日至2023年6月9日DETT领域已发表文献，提取文献特征，使用VOSviewer_1.6.18软件对所纳入文献的期刊、国家、机构、作者、关键词进行网络可视化分析，分析国内外DETT研究热点方向并预测未来技术发展走向。结果:共纳入1 333篇英文文献、617篇中文文献。自2006~2023年，中英文文献发表数量稳定增加，主要发表于内镜及消化领域专业期刊，近4年发文量有下降趋势。发文国家主要集中于美国、中国和日本，研究机构中美国约翰霍普金斯大学发文量最多，日本昭和大学篇均被引次数最高，日本学者Inoue Haruhiro为发文量最多、总被引用次数最高的研究者。关键词聚类分析显示国内外研究方向趋于一致，经口内镜下肌切开术(POEM)是DETT领域研究热点，不同聚类间基本按DETT的临床应用进行划分；时序分析显示腔镜及经自然腔道内镜手术(NOTES)为该领域兴起的基石，POEM的出现将DETT发展推向高潮，POEM相关衍生技术是现今及未来的发展方向。结论:国内外DETT相关研究呈现蓬勃发展之势，从其出现至今已延伸出多样化的超级微创技术(SMIS)，我国在这一领域的贡献不容低估，研究的活跃度及先进性均处国际水平，未来我国研究者应加强区域间联系，注重国际交流合作。
Abstract
Objective:This study aimed to provide a comprehensive overview of the current state of publications and research trends in the field of digestive endoscopic tunnel technique (DETT), both in China and internationally, from 2006 to the present.Methods:A systematic search was conducted in the Web of Science and China National Knowledge Infrastructure databases to identify relevant literature of DETT published between January 1, 2006, and June 9, 2023. In order to analyze the hotspots of domestic and international research of DETT and to predict the future technological development, the characteristics of the included literature were extracted and analyzed using VOSviewer_1.6.18 software, which facilitated network visualization of journals, countries, institutions, authors, and keywords.Results:A total of 1, 333 English articles and 617 Chinese articles were included in the analysis. The number of publications in both Chinese and English has steadily increased since 2006, with a gradual decline in the past four years. Most publications were found in specialized journals in the field of endoscopy and gastroenterology.The United States, China, and Japan were the primary countries of publication, with Johns Hopkins University having the highest number of publications and Showa University having the highest number of citations per article.In terms of authors, Inoue Haruhiro had the most publications.Keyword clustering analysis revealed similar research trends in China and abroad. Peroral oral endoscopic myotomy (POEM) emerged as a prominent hotspot in submucosal endoscopy technology, with the most comprehensive clusters representing various applications of the technology.Overlay visualization demonstrated that endoscopy and natural orifice transluminal endoscopic surgery (NOTES) were foundational to the field, thereafter the emergence of POEM worked up to a climax. POEM-derived new techniques indicated the current and future directions of this field.Conclusion:The research on DETT, both domestically and internationally, has experienced significant growth. This field has witnessed the emergence of various super minimally invasive diagnostic and therapeutic techniques. China has made substantial contributions to this field, with a high standard of vitality and advancement reaching international level.In the future, Chinese researchers should place emphasis on strengthening inter-regional and international collaborations.
