Summary
Major complications from endoscopic retrograde cholangiopancreatography (ERCP) are linked to therapeutic procedures and lower patient volumes. Centralizing ERCP in specialized centers can improve patient safety and reduce adverse events.
Area of Science:
- Gastroenterology
- Endoscopic Procedures
- Patient Safety
Background:
- Lack of multicenter prospective studies on diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP) complications.
- Need for data on ERCP-related adverse events across different healthcare settings.
Purpose of the Study:
- To investigate the incidence and risk factors of major complications associated with diagnostic and therapeutic ERCP.
- To evaluate the impact of procedural type and center volume on ERCP outcomes.
Main Methods:
- Prospective study of 2769 patients undergoing ERCP across nine centers over two years.
- Data collection on major complications, including pancreatitis, cholangitis, hemorrhage, and perforation.
- Comparison of complication rates between diagnostic and therapeutic ERCP, and analysis of risk factors.
Main Results:
- Overall major complication rate was 4.0%, with higher rates in therapeutic ERCP (5.4%) versus diagnostic ERCP (1.38%).
- Independent risk factors for complications included low center volume (small centers) and precut sphincterotomy.
- Specific risk factors identified for pancreatitis, cholangitis, hemorrhage, and duodenal perforation.
Conclusions:
- Therapeutic ERCP procedures and low case volume are primary drivers of major complications.
- Centralization of ERCP services in high-volume referral centers is recommended to enhance patient safety.
- Optimizing the use of precut techniques may further reduce ERCP-related adverse events.
