Negative Pressure Therapy After Infected Mesh Removal.

The surgeon will not know the patient's arm of study before the operation. Once the wound will be closed, we will let know what kind of closure the patient will need. Negative pressure therapy will be the same in all patients, in order to mantain homogeneity. We will set appointments each day while he is hospitalized, and after the discharge: at 7 (+/- 1) and 30 (+/- 5). We will collect demographic data before and during surgery, as well as in the postoperative period, including appointments.
