Summary
This study found that ERCP simulators can distinguish between expert and novice skills based on procedure time. However, the simulator did not show improvement over time with increased trainee experience.
Area of Science:
- Medical Simulation
- Gastroenterology Training
- Endoscopic Retrograde Cholangiography (ERCP)
Background:
- Endoscopic retrograde cholangiography (ERCP) is a high-risk procedure.
- Computerized simulators are useful for flexible endoscopy training.
- Limited data exist on simulator use for ERCP training.
Purpose of the Study:
- Assess ERCP simulator's ability to differentiate skill levels.
- Evaluate simulator responsiveness to increasing trainee experience.
Main Methods:
- Prospective parallel-arm cohort study.
- Novice fellows and expert faculty performed simulated ERCP cases.
- Primary outcome: total procedure time.
Main Results:
- Experts completed simulated ERCP faster than novices at baseline (p=0.026).
- No significant difference in time improvement between sessions for novices and experts (p=0.402).
Conclusions:
- The ERCP simulator effectively differentiated between expert and novice skill levels.
- The simulator did not demonstrate responsiveness to skill improvement over time.

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
