A porcine model for laparoscopic ventral hernia repair.

Ventral hernia repair is one of the most common abdominal operations. Recurrence rate remains high despite all preventive measures. "Tension-free" repair has been postulated as the surgical method of choice. A laparoscopic approach to ventral hernia repair has been described recently. Theoretical advantages of a laparoscopic repair include faster recovery, less postoperative pain, less morbidity, and a better cosmetic result. However, the approach requires advanced laparoscopic skills and familiarity with its technique. An animal model of ventral hernia, suitable for laparoscopic repair, was developed to be used for educational and experimental purposes. The model is simple, reliable, and reproducible in any minimally invasive surgery facility. We conclude that the pig can be used as an excellent model to learn the technique and evaluate a variety of endpoints for laparoscopic ventral hernia repair.
