摘要

Diverticulitis, an inflammation of colonic diverticula, poses significant clinical challenges due to its rising global incidence and potential complications. Modern dietary habits, sedentary lifestyles, and aging populations contribute to its increasing prevalence, with a notable rise among younger adults. Despite extensive research, a comprehensive assessment of global research trends remains limited. This study conducts a bibliometric and statistical analysis of diverticulitis research (1980–2024) to identify key trends, influential studies, international collaborations, and the correlation between national GDP and research output while projecting future publication trends. A bibliometric analysis of the Web of Science database identified 4459 publications, with 3653 articles, reviews, and meeting abstracts included. The United States led global research contributions (34.22%), followed by Italy and Germany. A strong positive correlation was found between national GDP and research productivity (r = 0.900, P < 0.001). Future projections estimate 289 publications in 2025. The most cited study was Rafferty et al.‘s 2006 “Practice parameters for sigmoid diverticulitis.” Citation analysis revealed growing academic interest, particularly in the past two decades. Diverticulitis has become a global health concern, driven by lifestyle changes and aging demographics, with an increasing incidence among younger populations. This study highlights a marked rise in research activity, predominantly in economically developed nations, and underscores the need for further investigation into prevention, diagnosis, and management strategies. These findings offer valuable insights for clinicians and researchers, guiding future research directions in diverticulitis.
