Complex tasks on virtual reality simulators (VRS) showed a minimal impact on novice surgeons’ laparoscopic skills. While basic skills training led to faster overall progression, complex skills training resulted in slower, longer learning curves.
Area of Science:
- Surgical Education
- Medical Simulation
- Laparoscopic Surgery Training
Background:
- Novice surgeons require effective training methods for laparoscopic procedures.
- Virtual reality simulators (VRS) offer a controlled environment for surgical skill acquisition.
Purpose of the Study:
- To evaluate the impact of complex tasks within VRS training on novice laparoscopic surgeons' learning.
- To compare the effectiveness of basic skills versus basic and complex skills training on VRS.
Main Methods:
- Fifty-five medical students were randomized into two groups: basic skills only (Group A) or basic and complex skills (Group B).
- Participants underwent two training sessions on VRS, with evaluations before and after each session.
- Performance was assessed by blind evaluation of intracorporeal suture achievement using both left and right hands.
Main Results:
- Both groups showed significant improvement in time and technical scores (P < 0.05).
- Group B demonstrated slower and longer progression compared to Group A.
- No significant differences were found between groups when left and right hand results were combined, but the first hand trained was faster in Group B at the third session (P=0.04).
Conclusions:
- Complex skills training on VRS had a late and minimal effect on reducing intracorporeal suture execution time.
- Training with complex skills led to a slower and longer overall learning progression compared to basic skills alone.
