Summary
This study validated a laparoscopic simulator box and games. Results show it is an effective tool for training surgical skills in both medical students and experienced surgeons.
Area of Science:
- Surgical Education
- Medical Simulation
- Laparoscopic Surgery Training
Background:
- Acquiring laparoscopic skills in the operating room depends on tutor expertise and trainee practice.
- Laparoscopic simulators require validation before use by students and surgeons for skill development.
Purpose of the Study:
- To validate a designed laparoscopic simulator box with interchangeable training games.
- To assess the construct, content, and face validity of the simulator for surgical training.
Main Methods:
- A simulator box with 6 games was designed and validated by 19 surgical experts and 20 medical students.
- Construct validity was evaluated by time-to-completion and successful game completion.
- Content and face validity were assessed using Likert-scale questionnaires (1-5).
Main Results:
- Experts completed games faster and more successfully than non-experts (p < 0.01).
- Non-experts rated content validity highly (≥ 4), while experts questioned the simulator's necessity for learning (mean score 3.68, p < 0.01).
- Face validity was high (≥ 4) for most items, except spatial realism (3.82).
Conclusions:
- The validated laparoscopy simulation box and games serve as effective training tools.
- The simulator is a valid means for developing essential laparoscopic technique skills in both trainees and surgeons.
