Prevention of Trocar Site Incisional Hernia Following Laparoscopic Ventral Hernia Repair

BACKGROUND AND OBJECTIVES Trocar-site incisional hernia following laparoscopic ventral hernia repair is reported to have a relatively high incidence. The main reasons are trocar diameter and design, pre-existing fascial defects, and some operation- and patient-related factors. The aim of this article to show a new technique of ventral hernia repair that could prevent trocar site incisional hernia. METHODS After establishing the pneumoperitoneum, three 5-mm ports are inserted in positions according to the site and size of the hernia. The procedure begins by dissection of the adhesions of bowel loops or omentum (if any) from the hernia to clear a good margin for mesh coverage. Then a single 10-mm to 15-mm port (mesh insertion port) is inserted in the center of the ventral hernia depending on the size of the mesh. The mesh is fixed in position with a 5-mm tacker. The peritoneum and underlying superficial fascia are carefully closed before closing the skin. RESULTS A total of 35 patients were recruited for this method. The mean hospital stay was 1.5 days, the mean age was 50.35 years and the mean operative time was 40 minutes. In all patients, 10x15-cm ePTFE was used. No single incidence of trocar-site incisional hernia occurred during a mean follow-up of 2 years. Three (8.57%) patients developed complications and no mortality was reported. CONCLUSION The mesh introduction through the port, which is situated at the center of the hernia defect is a simple, cost-effective technique and will prevent trocar-site incisional hernia.
