Endoscopic Skills Training: The Impact of Virtual Exercises on Simulated Colonoscopy

Area of Science:

• Medical Simulation
• Gastroenterology Training
• Surgical Skills Development

Background:

• Previous research indicated psychomotor training enhances colonoscopy performance.
• The latest GI Mentor® incorporates new virtual reality exercises.
• Optimizing colonoscopy training requires evaluating novel simulation techniques.

Purpose of the Study:

• To assess the impact of three specific virtual reality exercises on simulated colonoscopy skills.
• To determine the effectiveness of Endobubble I, Navigation I, and Mucosal Evaluation I in training.
• To optimize colonoscopy training programs through virtual simulation.

Main Methods:

• Prospective, randomized study with 19 residents.
• Intervention group (n=10) trained on Endobubble I, Navigation I, and Mucosal Evaluation I to expert level.
• Control group (n=9) performed standard simulated colonoscopies; both groups assessed on final case.
• Learning curves and skills transfer evaluated using mucosal surface examined, time to cecum, screening efficiency, and patient pain duration.

Main Results:

• Endobubble I and Navigation I demonstrated construct validity, with experts performing faster than novices.
• The intervention group reached the cecum significantly faster (278 vs. 356 s) and had higher screening efficiency (83% vs. 75%).
• Skills transfer showed the control group took longer to reach the cecum and experienced more patient pain (9% vs. 6%).

Conclusions:

• Psychomotor training significantly impacts the acquisition and assimilation of colonoscopy skills.
• Endobubble I and Navigation I are recommended for novice training programs.
• Virtual reality simulation effectively enhances colonoscopy procedural skills and efficiency.
