中外消化内镜微创切除十年发展史的文献循证可视化分析

Evidence-based visualization analysis of literature of digestive endoscopic minimally-invasive resection in the past decade

目的总结中外消化内镜微创切除领域近十年的发文现状及趋势。方法在Web of Science和中国知网数据库中检索2011-01-01—2021-07-17消化内镜微创切除领域文献,采用VOSviewer 1.6.11软件对纳入文献的国家、机构、作者及关键词的聚类及时序进行分析,绘制对应的循证可视化图谱,分析国家、学术机构、研究者间合作关系,比较中、英文数据库研究主题差异,预测未来研究热点和发展方向。结果共纳入22834篇英文文献及4636篇中文文献,近十年来中、英文文献数目均稳步增长,均以学科专业杂志载文较多。发表文献数量以中日韩及美国较多,均超过2000篇;日本国立癌症中心发文497篇,是发文最多的机构。发文学术机构间的合作呈现出明显的地域性,机构及学者间的合作有待加强。关键词聚类方面,中、英文文献的研究领域聚类相比差异不大,中文文献多出内镜护理与配合及消化道黏膜下肿瘤相关聚类。中、英文关键词时序分析显示,内镜外科、隧道技术和黏膜下肿瘤可能是热点及发展方向。结论中外消化内镜微创切除经历了蓬勃发展的十年,文献数量持续增加,中国在国际舞台上的地位逐步提高。中文文献聚焦主题的先进性与英文文献基本持平,也展现出一定的中国特色。未来应加强区域间合作,重点关注热点方向。

Objective To review publications in the field of digestive endoscopic minimally-invasive resection in the past 10 years in and outside China.Methods Literature of digestive endoscopic minimally-invasive resection in the Web of Science and GNKI databases from January 1,2011 to July 17,2021 was retrieved.VOSviewer 1.6.11 was used for clustering and time series analysis of countries,institutions,authors and keywords,and drawing evidence-based visualization maps,so as to analyze the cooperation among countries,academic institutions and researchers,to compare the differences in research topics between Chinese and English databases,and to predict the future research hot spots and directions.Results A total of 22834 English articles and 4636 Chinese articles were included.Over the past 10 years,the number of Chinese and English publications has been growing steadily,and most of them were published in professional journals.The publications were mainly from China,Japan,South Korea and the United States,where all exceeded 2000.The National Cancer Center of Japan had 497 publications,ranking the first among all institutions.The cooperation between academic institutions showed obvious regional characteristifs,and the inter-institutional and interpersonal cooperation needed improvement.In terms of keyword clustering,there was no significant difference between Chinese and Flnglish publications,but there were two additional clusters in Chinese publications,endoscopic nursing and submucosal tumor.Overlays analysis of key words showed that endoscopic surgery,tunneling technique,and submucosal tumor could be hot spots and future directions.Conclusion Digestive endoscopic minimally-invasive resection has experienced a vigorous development in the past 10 years with a growing number of Chinese and English publications.China is playing an increasingly important role on the international stage.The advanced nature of research focus in Chinese publications is comparable to that in Knglish publications,yet also showing Chinese characteristics.In the future,more efforts should be taken to strengthen regional cooperation and focus on research hot spots.
