This randomized controlled trial evaluated the feasibility of novice learners constructing inguinal hernia models for simulation-based training in open inguinal hernia repair. Conducted with 48 second-year medical students, the study found that those who built models reported greater confidence in understanding inguinal canal anatomy and made fewer procedural errors during simulation tasks, with significant results in executional errors (p = 0.03) and procedural errors (p = 0.05).
Key findings
- Model-building participants reported greater confidence in understanding inguinal canal anatomy (p = 0.004).
- Fewer executional errors were made during external oblique aponeurosis exposure in the model-building group (p = 0.03).
- Fewer procedural errors occurred during wound closure in the model-building group (p = 0.05).
- Model-building participants were more likely to complete hernia sac resection within the allotted time (p = 0.04).
Why it matters
This study highlights the potential of learner-led model construction as an effective educational tool in surgical training, enhancing both anatomical understanding and technical performance. Such approaches may improve training outcomes in surgical education.
