A Bibliometric and Visual Analysis of Obesity and Gastroesophageal Reflux Disease

Abstract

Abstract Aim To assess the research status, hotspots, and frontiers related to obesity and gastroesophageal reflux disease (GERD) using bibliometric approaches. Material and Methods Bibliometric analysis of the field of obesity and GERD was conducted based on database of the Web of Science Core Collection (WOSCC) from its inception to October 20, 2022. Several factors are analyzed and mapped using VOSviewer software, including the total number of publications, the number of resources and journals, countries, authors, and intellectual networks, as well as the co-citation analysis of keywords and references. Results A total of 2,306 papers from 480 journals with 10,010 authors from 2,628 institutes in 75 countries were included. There was an increase in publishing papers and citations each year. Most of the publications were authored by researchers from the United States and Italy. In the collaboration network map, Mayo Clinic, Karolinska Institute, the University of Washington had the largest cluster of nodes. Lagergren J, Corley DA, Whiteman DC, Vaughan TL, and Patti MG were the most prolific authors. There was a high concentration of research into bariatric surgery (BS), risk factors, body mass index (BMI), and Barrett's esophagus in this field. Future research may focus on weight gain, sleep apnea, sleeve gastrectomy (SG), and revisional bariatric surgery. Conclusions We summarized the research hotspots and trends, collaborative network, and future research directions in the field of obesity and GERD. In addition to help scholars understand essential information, our results will also enable them to identify research frontiers.
