To describe the development process and structural relationships of scientific achievements in endoscopic ultrasonography (EUS) in pancreatic tumors over the past decades and to reveal the key research topics using bibliometric analysis.
All relevant publications covering the research of EUS in pancreatic tumors from 1984 to 2021 were involved through the Web of Science Core Collection. R-bibliometrix was used to conduct the bibliometric analysis, and VOSviewer software was used to explore the hot spots and networks related to this field.
Between 1984 and 2021, 4071 publications were involved. The number of annual publications increased from 1 to 310. The United States contributed the most publications to this field (n=1433, 35.20%), followed by Japan (n=827, 20.31%) and Germany (n=319, 7.84%). There was active cooperation between countries/regions. Gastrointestinal Endoscopy (GIE) was the most productive journal and the most influential journal. Professor Giovannini M, who produced the most publications, had a great influence on this research. The focus in this field was clarified by analyzing the top 10 citations and co-citations publications. Moreover, the analysis of the keywords showed Important topics: "Classification of pancreatic tumor disease" "Development of EUS in the diagnosis of pancreatic tumor diseases," and "Development of EUS in the treatment of pancreatic tumor diseases."
For the first time, bibliometric analysis was used to gain a deep understanding of the global trends of studies investigating EUS in pancreatic tumor diseases. The EUS field is rapidly evolving, and our study may be a critical reference for clinical researchers related to this field.
描述过去几十年内镜超声检查（EUS）在胰腺肿瘤科学成果的发展过程和结构关系，并通过文献计量分析揭示关键研究主题。
通过Web of Science核心合集纳入1984年至2021年所有关于EUS在胰腺肿瘤研究方面的相关出版物。使用R-bibliometrix进行文献计量分析，并用VOSviewer软件探索该领域的热点和网络。
1984年至2021年期间，共纳入4071篇出版物。年出版物数量从1篇增加到310篇。美国在该领域的出版物贡献最多（n = 1433，35.20%），其次是日本（n = 827，20.31%）和德国（n = 319，7.84%）。国家/地区之间有积极的合作。《胃肠内镜》（GIE）是发文量最多且最具影响力的期刊。发表出版物最多的乔瓦尼尼·M教授对该研究有很大影响。通过分析被引频次和共被引频次最高的前10篇出版物，明确了该领域的研究重点。此外，关键词分析显示了重要主题：“胰腺肿瘤疾病分类”“EUS在胰腺肿瘤疾病诊断中的发展”以及“EUS在胰腺肿瘤疾病治疗中的发展”。
首次使用文献计量分析深入了解全球范围内研究EUS在胰腺肿瘤疾病中的趋势。EUS领域正在迅速发展，我们的研究可能为该领域的临床研究人员提供关键参考。
