Summary
Computer-based simulators effectively train novice endoscopists in basic skills, improving procedure completeness and reducing the need for instructor assistance during upper endoscopy (UGE). This simulation enhances manual dexterity for medical education.
Area of Science:
- Medical Education
- Gastroenterology
- Surgical Simulation
Background:
- Medical training faces time constraints and limited patient availability.
- Computer-based simulators offer manual skills training without patient contact.
- This study evaluates a computer-based simulator for upper endoscopy (UGE) training.
Purpose of the Study:
- To prospectively compare the efficacy of computer-based simulation versus traditional training for upper endoscopy (UGE).
- To assess the impact of simulation on trainee performance and instructor assessment.
Main Methods:
- Twenty-two endoscopy fellows were randomized into two groups: simulator pre-training (10 hours) and no pre-training.
- All trainees performed 19-20 patient upper endoscopies.
- Performance metrics included esophageal intubation, procedure completeness, duration, assistance requests, and instructor evaluation.
Main Results:
- The simulator-pretrained group showed significantly higher procedure completeness (87.8% vs. 70.0%) and fewer assistance requests (41.3% vs. 97.9%).
- Instructors rated performance more positively for the pretrained group (86.8% vs. 56.7%).
- Procedure duration was similar between groups.
Conclusions:
- Computer-based simulators effectively equip novice trainees with essential endoscopic skills.
- Simulation training reduces the need for direct instructor assistance in upper endoscopy.
- This technology enhances the acquisition of anatomical landmark identification and basic endoscopic maneuvers.
