Summary
This study developed a low-cost laparoscopic myomectomy simulation model. The model proved valid for training, with experts outperforming novices, enhancing surgical readiness.
Area of Science:
- Surgical Simulation
- Gynecologic Surgery Training
- Medical Education Technology
Background:
- Traditional surgical training has limitations for practicing complex procedures safely.
- Existing simulation models for gynecologic surgery are insufficient for laparoscopic myomectomy.
- There is a need for accessible, effective training tools for laparoscopic myomectomy.
Purpose of the Study:
- To design and validate a low-cost, low-fidelity simulation model for laparoscopic myomectomy.
- To assess the model's effectiveness as a training tool for surgical skills.
- To evaluate the model's realism and educational impact.
Main Methods:
- Constructed a low-cost simulation model using readily available materials.
- Recruited expert and novice surgeons for participation.
- Assessed performance using validated laparoscopic skills scales and a post-task survey.
- Compared task completion times and scores between expert and novice groups.
Main Results:
- The model cost under $5 to construct.
- Experts demonstrated significantly shorter task completion times and higher scores than novices.
- High interrater reliability (ICC > 0.95) was achieved for scoring.
- Participants found the model realistic for fibroid enucleation and hysterotomy repair.
Conclusions:
- The developed low-cost simulation model is valid for laparoscopic myomectomy training.
- The novel assessment scale effectively differentiates between expert and novice performance.
- This simulation tool can improve surgical trainees' readiness for the operating room.
