In brief
This study validates a low-cost simulation model for teaching laparoscopic inguinal hernia repair in boys, demonstrating high fidelity and educational value across 34 university programs. Both residents and expert surgeons rated the trainer favorably for realism, accessibility, and effectiveness in developing basic laparoscopy skills.

Abstract
Purpose
To examine the fidelity of our model of laparoscopic inguinal hernia repair (LIHR) in boys and evaluate its value in resident training programs and the learning of basic laparoscopy skills.
Methods
We created a simulation model with inexpensive, easy-to-obtain equipment. Study participants from 34 university hospital departments received a user manual and an evaluation questionnaire (11 items rated on a 5-point Likert scale). We considered that the evaluation was positive when the median overall score was 4 or over. We compared the results for residents (n=26) vs. expert surgeons (n=29) (t tests).
Results
The duration of the procedure was significantly longer among the residents (30.0±16.8 min) than among the expert surgeons (20.5±11.7 min; p=0.01). In both groups, the participants rated the model favorably with regard to the overall impression (median score: 4.0±1.0), realism (4.0±0.9), ease of access to the required equipment (5.0±0.6), the quality of the user manual (5.0±0.6), ease of assembly (5.0±0.8), ease of the procedure (5.0±0.8), value in resident training programs (4.0±0.9), and value in learning basic laparoscopy skills (5.0±0.8)). The evaluation was positive (4.0±0.9).
Conclusion
Our low-cost model was an effective teaching and training tool for LIHR and basic laparoscopy skills.
