Research Trends on Post-ERCP Complications: Focus on Pancreatitis, Perforation, and Infections

<b>Introduction:</b> Endoscopic retrograde cholangiopancreatography (ERCP) is widely used in the management of biliary andpancreatic disorders but carries a significant risk of complications, including post-ERCP pancreatitis (PEP), cholangitis,haemorrhage, and duodenal perforation. Despite technological advancements, these adverse events remain a global concern.A bibliometric analysis can elucidate publication trends, collaborative networks, and emerging themes in this evolving field.<b>Aim:</b> To analyze global research trends, authorship patterns, institutional and country contributions, and thematic shifts in post-ERCP complication research published between 2019 and 2025.<b>Methods:</b> A bibliometric analysis was conducted using the Scopus database. Articles and reviews in English, published between January 2019 and April 2025, were retrieved using a structured search strategy targeting ERCP complications. Data were analyzed using Microsoft Excel and VOSviewer (v1.6.20) to map publication trends, co-authorship networks, institutional output, country distribution, and keyword co-occurrence.<b>Results:</b> A total of 3,113 publications met the inclusion criteria. The number of articles increased steadily, peaking in 2024.The United States, Japan, and China were the most prolific contributors. "Post-ERCP pancreatitis" emerged as the dominanttheme, while recent years showed increasing focus on prevention, prediction models, and artificial intelligence. Collaborationwas highly centralised among high-income countries, with limited representation from low- and middle-income regions.<b>Conclusions:</b> Global research landscape on ERCP complications is expanding, with a shift towards data-driven and preventivestrategies. However, disparities in research quality, institutional dominance, and limited international inclusivity persist.Greater global collaboration and targeted capacity-building are essential to ensure equitable progress in ERCP safety andcomplication management.
