Laparoscopic surgery reduces, but not eliminates, the rate of incisional hernia. It is accepted that large trocar orifices should be sutured, in order to prevent future herniation. In morbidly obese patients, the closure of the anterior fascia is a very difficult job, and it does not prevent from preperitoneal herniation. Ventralex composite mesh is a very easy-to-place device, which closes satisfactorily both the peritoneal opening and the subcutaneous trocar pathway. We recommend its use for large diameter orifices and Hasson orifices in bariatric patients.
