Visualizing global progress and challenges in esophagogastric variceal bleeding.

BACKGROUND

Esophageal and gastric variceal bleeding is a catastrophic complication of portal hypertension, most commonly caused by cirrhosis of various etiologies. Although a considerable body of research has been conducted in this area, the complexity of the disease and the lack of standardized treatment strategies have led to fragmented findings, insufficient information, and a lack of systematic investigation. Bibliometric analysis can help clarify research trends, identify core topics, and reveal potential future directions. Therefore, this study aims to use bibliometric methods to conduct an in-depth exploration of research progress in this field, with the expectation of providing new insights for both clinical practice and scientific research.

AIM: To evaluate research trends and advancements in esophagogastric variceal bleeding (EGVB) over the past twenty years.

METHODS

Relevant publications on EGVB were retrieved from the Web of Science Core Collection. VOSviewer, Pajek, CiteSpace, and the bibliometrix package were then employed to perform bibliometric visualizations of publication volume, countries, institutions, journals, authors, keywords, and citation counts.

RESULTS

The analysis focused on original research articles and review papers. From 2004 to 2023, a total of 2097 records on EGVB were retrieved. The number of relevant publications has increased significantly over the past two decades, especially in China and the United States. The leading contributors in this field, in terms of countries, institutions, authors, and journals, were China, Assistance Publique-Hôpitaux de Paris, Bosch Jaime, and World Journal of Gastroenterology, respectively. Core keywords in this field include portal hypertension, management, liver cirrhosis, risk, prevention, and diagnosis. Future research directions may focus on optimizing diagnostic methods, personalized treatment, and multidisciplinary collaboration.

CONCLUSION

Using bibliometric methods, this study reveals the developmental trajectory and trends in research on EGVB, underscoring risk assessment and diagnostic optimization as the core areas of current focus. The study provides an innovative and systematic perspective for this field, indicating that future research could center on multidisciplinary collaboration, personalized treatment approaches, and the development of new diagnostic tools. Moreover, this work offers practical research directions for both the academic community and clinical practice, driving continued advancement in this domain.
