Effective Low-Cost Simulation for Surgical Skills Training

A novel foam model enhances residents’ confidence in abdominal procedures.

• Residents’ overall comfort with ostomy techniques rose by 2 points after training (p < 0.001).
• Specific skills improved: siting the stoma (+1 point), creating trephine (+2 points), securing stoma (+1 point).
• For abdominal access methods, confidence increased: Veress needle (+2), optical trocar (+1), Hasson (+1.5).

This low-fidelity simulation offers a practical, risk-free training tool for critical surgical skills.
