Global status of research on Barrett’s esophagus based on the Web of Science core collection (2016–2025): a bibliometric analysis
Abstract
Background Barrett’s esophagus (BE) is the key precursor to esophageal adenocarcinoma (EAC). With the rapid evolution of BE management—including the emergence of non-endoscopic screening modalities such as the capsule sponge and the integration of artificial intelligence (AI) into endoscopic surveillance—a comprehensive understanding of the global research landscape over the past decade is clinically imperative to inform surveillance strategies, early intervention, and precision care. This study therefore aimed to systematically characterize the global research landscape of BE over the past decade by using bibliometric and visualization analysis to map publication trends, collaboration networks, co-citation structures, and keyword clusters, thereby identifying the evolving research hotspots and intellectual foundations of the field. Methods A systematic literature retrieval was performed in the Web of Science Core Collection (WoSCC) on October 14, 2025, covering publications from January 1, 2016 to August 8, 2025. The search strategy was based on title-field terms covering all Barrett’s esophagus synonyms. Inclusion criteria included: original research articles focused on BE. Exclusion criteria were: non-English publications, letters, case reports, editorials, meeting abstracts, and studies unrelated to BE. A total of 1,239 articles were retained and analyzed using CiteSpace (version 6.3.R1), EndNote X9, and GraphPad Prism 9.3.1 to evaluate annual publication trends,…
