Advanced endoscopy trainees (AETs) show significant variability in their endoscopic retrograde cholangiopancreatography (ERCP) learning curves. Case volume alone does not guarantee competence, particularly for challenging native papilla cannulations.
Area of Science:
- Gastroenterology
- Medical Education
- Endoscopic Procedures
Background:
- Limited data exists on the learning curves and competence acquisition for Endoscopic Retrograde Cholangiopancreatography (ERCP).
- Standardized assessment tools are crucial for objectively evaluating proficiency in complex endoscopic procedures.
Purpose of the Study:
- To prospectively define ERCP learning curves among advanced endoscopy trainees (AETs).
- To measure AET competence using cumulative sum (CUSUM) analysis and a standardized assessment tool.
Main Methods:
- AETs were evaluated using a standardized ERCP competency assessment tool from their 26th case onwards.
- Cumulative sum (CUSUM) analysis was applied to track learning curves for technical and cognitive ERCP components.
- Sensitivity analyses were performed with varying definitions of success and failure rates.
Main Results:
- Five AETs underwent 1049 graded ERCPs, predominantly for biliary indications.
- Significant variability was observed in individual learning curves for ERCP technical and cognitive skills.
- While most AETs achieved competence in overall cannulation, none mastered native papilla cannulation.
Conclusions:
- ERCP learning curves exhibit substantial inter-trainee variability.
- Achieving competence in ERCP, especially native papilla cannulation, is not solely dependent on case volume.
- Standardized assessment and targeted training are essential for developing ERCP proficiency.
