Abstract:
Objective:To quantitatively analyze the primary research characteristics and keywords of international and domestic papers in the field of capsule endoscopy with bibliometric methods, and to illustrate the progression of capsule endoscopy research and offer insights for researchers in this domain.Methods:The Stork and visualized software CiteSpace were used to search and analyze the literature on "capsule endoscopy" in the English database of PubMed and the Chinese database of CNKI from 2002 to 2022.Results:A total of 6 011 English articles were identified in the PubMed database during the specified period. Both the number of publications and their citation frequencies displayed an upward trend on a global and domestic scale. The growth rates of global and domestic English publications were 5% and 15%, respectively, with major contributions coming from the United States, Japan, China, Italy and Germany. Key areas of global research interest included magnetic capsule endoscopy, colon capsule endoscopy, inflammatory bowel disease, small bowel capsule endoscopy, capsule endoscopy images, and obscure gastrointestinal bleeding, etc. A total of 2 027 articles were retrieved in the CNKI database, with top three research institutions including Department of Gastroenterology, Changhai Hospital, Naval Medical University; Department of Gastroenterology, Nanfang Hospital, Southern Medical University; School of Electronic Information and Electrical Engineering, Shanghai Jiao Tong University. Emerging research keywords encompassed artificial intelligence, deep learning, and guidelines.Conclusion:The study reveals a gradual increase in global research activities related to capsule endoscopy, with China demonstrating significant international academic influence in this field.
