A new, inexpensive silicone model for Laparoscopic Appendectomy (LA) simulation significantly improved surgical residents' confidence and performance. This low-cost tool provides valuable foundational skills for performing real LA procedures.
Area of Science:
- Surgical Education
- Medical Simulation
- Minimally Invasive Surgery
Background:
- Appendectomy is a frequent procedure for surgical residents.
- Current training methods may lack sufficient hands-on experience for minimally invasive approaches.
Purpose of the Study:
- To assess the fidelity, usefulness, and educational value of a novel, low-cost silicone model for Laparoscopic Appendectomy (LA) simulation.
- To evaluate the model's impact on surgical residents' confidence and foundational skills in an introductory laparoscopy course.
Main Methods:
- A new silicone model for LA simulation was developed and tested.
- First-year general surgery residents participated in an introductory laparoscopy course utilizing the model.
- Performance was assessed using a specific scale, and participants completed a post-course questionnaire.
Main Results:
- Residents with more experience using the model demonstrated higher execution, quality, and global performance.
- The model was considered adequate, with high face and content validity.
- 97% of participants felt they learned solid foundations for LA, and most agreed the model increased confidence for real procedures.
Conclusions:
- The new low-cost laparoscopic appendectomy model is validated for face, content, and construct.
- Integrating this model into introductory courses enhances surgical residents' confidence and provides valuable foundational training for laparoscopic appendectomy.
