摘要
背景与目的:近年来,减重代谢外科发展迅速,新的术式不断涌现、理念不断更新,同时,由此所产生的大量文献为进一步的科学研究奠定了基础。因此,本研究通过对2021年减重外科领域的英文文献的计量可视化分析,探讨该领域进展和研究热点,为今后的临床与科研的发展方向提供参考。方法:检索Web of Science数据库2021年收录的减重代谢外科领域英文文献,采用文献计量学方法对文献数量、机构来源、发表期刊、关键词等进行分析。结果:最终纳入5335篇文献进行分析,发文量前三的国家分别为美国、中国、意大利;发文量前三的机构为哈佛医学院(n=204)、密歇根大学(n=141)和圣保罗大学(n=135);发文量前三的期刊为Obesity Surgery(n=510)、Surgery for Obesity and Related Diseases(n=221)及Nutrition Metabolism and Cardiovascular Diseases(n=157);美国是对外合作最多及最广的国家,虽然中国的发文量位列世界第二,但在对外合作方面仅位列第十二;哈佛医学院(90次)、梅奥诊所(70次)及密歇根大学(41次)是世界对外合作量排名前三的机构;2021年减重外科研究方向除侧重于外科手术外,还包括了与心血管、营养学、癌症等方面相关的研究;引证网络分析中“Once-weekly semaglutide in adults with overweight or obesity”是2021年减重外科领域中最高被引文献(202次)。被引网络分析“Bariatric surgery versus intensive medical therapy for diabetes-5-year outcomes”为2021年该领域被引网络中被引用次数最高文献(179次);Obesity Surgery(1526次,发文量510),the New England Journal of Medicine(1355次,发文量2),Surgery for Obesity and Related Diseases(1246次,发文量221)等为该领域最高被引期刊。关键词共现网络中显示“Gut Microbiota”、“Glucose”是目前及未来该领域的研究热点及研究趋势。共被引分析网络图中Sjöström L(277次),Schauer PR(274次),Buchwald H(223次),为该领域的高被引作者。结论:在2021年美国发文量仍居世界第一,中国虽位居第二,但在外合作及学术影响力方面仍相对较弱。除外科手术外,心血管、营养、癌症等同样是该领域的研究侧重点。肠道菌群与肥胖症及相关代谢疾病的关系,以及减重手术对血糖的改善情况及作用机制仍然是目前及未来的研究热点。
Background and Aims:Over the past few years,bariatric and metabolic surgery has developed rapidly,as evidenced by the continuous emergence of new procedures and constant renewal of concepts.Meanwhile,the large amount of literature generated in this field has laid the foundation for further scientific research.Therefore,this study was conducted to analyze the research progress and hotspots in the field of bariatric and metabolic surgery through a bibliometric and visualized analysis of the English literature concerning this subject published in 2021,so as to provide a guidance for future clinical and basic science research.Methods:The English literature of studies in the field of bariatric and metabolic surgery in 2021 included in the Web of Science database were retrieved,and the literature number,source of institutions,publication journals and specific key words were analyzed based on bibliometrics methods.Results:A total of 5335 papers were finally included for analysis.The top three countries with the largest number of relevant papers were the United States,China,and Italy.Harvard Medical School,University of Michigan,and the University of Sao Paulo occupied the top three positions of the most prolific institutions.The top three journals with the most publications were Obesity Surgery(n=510),Surgery for Obesity and Related Diseases(n=221),and Nutrition Metabolism and Cardiovascular Diseases(n=157).The United States was the country with the most extensive foreign co-operation.China ranked second in the world in terms of the number of published papers,but only ranked the twelfth in terms of foreign co-operation.Harvard Medical School(90 times),Mayo Clinic(70 times),University of Michigan(41 times)were the top 3 institutions with the most extensive foreign cooperation.In addition to focusing on surgery,bariatric surgery research in 2021 also included the fields such as cardiovascular medicine,nutrition,and oncology."Once-weekly semaglutide in adults with overweight or obesity"was found to be the highest cited paper in citation network in the field of bariatric surgery in the 2021(202 times)."Bariatric surgery versus intensive medical therapy for diabetes-5-year outcomes"was the most cited paper in co-citation network(179 times).Obesity Surgery(1526 times,510 papers),the New England Journal of Medicine(1355 times,2 papers),Surgery for Obesity and Related Diseases(1246 times,221 papers)were found to be the most cited journals in this field.In the key word co-occurrence network,“Gut Microbiota”and“Glucose”presented the current and future popular research direction and trend in this field.Sjöström L(277 times),Schauer PR(274 times),Buchwald H(223 times)in the co-cited network,were the most highly cited authors in this field.Conclusion:In terms of publication volume in 2021,the United States still ranks the first in the world,and China ranks the second,but exhibits limited co-operation with other countries.In addition to focusing on surgery,cardiovascular medicine,nutrition and oncology are also the research priorities in this field.The association of intestinal flora with obesity and related metabolic diseases,as well as the effect of bariatric surgery on blood sugar improvement and its action mechanism,remain the current and future hot research topics.
