A retrospective analysis of 500 ERCP procedures: outcomes, adverse events, and risk factors over two years

Aims: Endoscopic retrograde cholangiopancreatography (ERCP) is a widely used procedure for both the diagnosis and management of biliary and pancreatic ductal diseases. While it has been largely replaced by non-invasive imaging techniques for diagnostic purposes, ERCP remains the gold standard for therapeutic interventions. This study aims to retrospectively analyze the outcomes, adverse events, and success rates of ERCP procedures performed on 500 patients over two years. Methods: A retrospective review of 500 ERCP procedures performed at a single center over 24 months was conducted. Patient demographics, indications for ERCP, procedural outcomes, and adverse event rates were collected and analyzed. Success rates for therapeutic interventions, as well as risk factors for post-procedural adverse events, were identified. Results: The study revealed that 448 (89.6%) of ERCP procedures were successful in achieving the primary therapeutic goal (e.g., stone extraction, stent placement). Adverse events occurred in 93 (18.6%) of cases, with post-ERCP pancreatitis being the most common adverse event (n: 73, 14.6%). Risk factors associated with adverse events included previous cholecystectomy (p
