Table 3_Research trends in post-ERCP pancreatitis: a dual-database bibliometric analysis.xlsx

Annual publication was sporadic before 1996 and peaked at 133 records in 2025. The United States contributed 485 publications, followed by China (306) and Japan (217), and maintained links with countries across all three collaboration clusters. Gastrointestinal Endoscopy published the most records (n = 170) and was the most frequently co-cited journal (n = 11,065).

Temporal analyses showed increasing attention to multimodal prevention and risk assessment. At the retrieval cutoff, adverse events and risk factors had the strongest ongoing keyword bursts, while artificial intelligence and machine learning remained emerging topics.</p>Conclusion<p>PEP research has moved toward multimodal prevention and individualized risk estimation. The literature remains concentrated in specialist endoscopy journals and established clinical networks, with substantial contributions from East Asia.

Broader multicenter collaboration and independent validation are needed before emerging prediction models can inform routine practice.</p>
