Abstract    Objective    To evaluate the publication status of literature related to pancreatic fistula in the past two decades through bibliometric and visualized analysis, and to analyze the current research hotspot and trend for the development of pancreatic fistula. Methods    The Web of Science (WOS) database was used to search the SCI literature about "pancreatic fistula" from January 1th 2001 to July 25th 2021. The number of documents issued by countries, institutions, journals, and the co-operation network of countries, research institutions, authors, and the co-citation network of documents, authors, journals, and the co-occurrence network of keywords were analyzed by CiteSpace (5.8.R1) software and Bibliometrics Online Analysis Platform (Bibliometric.com), and the corresponding visual knowledge graphs were drawn. Results    A total of 3507 Articles and 483 Reviews were enrolled in the analysis. The annual volume of SCI articles concerning pancreatic fistula maintained an upward trend. The United States, Japan and China accounted for the most publications. University of Heidelberg (n=107), Sichuan University (n=97) and University of Amsterdam (n= 96) occupied the top three of the number of papers published by research institutions. The journals with the largest number of articles were Journal of Gastrointestinal Surgery (n=233), HPB (n=185) and World Journal of Surgery (n=144). The co-operation network showed that the United States has the most extensive foreign cooperation, and Verona University, Heidelberg University and Zhejiang University were the research institutions with the most extensive foreign co-operation. Bassi C (Frequency=87), Malleo G (Frequency=61) and Salvia R (Frequency=56) had formed a close co-operation network. The top three highly cited literature in the citation network were: Bassi C (2017), Bassi C (2005) and Callery MP (2013). Bassi C (Frequency=2446), Wente MN (Frequency=909) and Yeo CJ (Frequency=893) were the highly cited authors in this field. Ann Surg (Frequency=3313), Surgery (Frequency=3141) and J Gastrointest Surg (Frequency=2667) were the most highly cited journals in this field. Pancreaticoduodenectomy (Frequency=1343), complication (Frequency=1131), international study group (Frequency=973) in the co-occurrence network were the research hotspots in the current stage, while ductal adenocarcinoma and laparoscopic pancreaticoduodenectomy demonstrated a new research trend. Conclusions    In the past two decades, the literature about "pancreatic fistula" has increased rapidly. CiteSpace software and other visual analysis tools can comprehensively and intuitively show the research status and development trend of "pancreatic fistula", and provide reference basis for further research in the future.
