The patients will be randomized into two groups of 100 subjects each one. One arm will be randomized to treatment with a negative topical pressure system (Sistema Prevena ); while the other arm ("control group") will be randomized to treatment with standard medication with sterile gauzes and a TNT patch or medicated patch as normal traditional medication in use.

The medications with a negative topical pressure system (Sistema Prevena ) will be applied directly in the Operating Room. Thereafter the medication will be checked in the inpatient ward after 48 hours from the intervention, evaluating the possible absorption of exudate on the surface. If no absorption are detected within 48 hours, the medication won't be removed. The medication will be renewed in the 7th day ( 2 days) post-operative; and to follow every 7 ( 2 days) until the points are removed. If the wound continues to progress towards recovery, the protocol will continue until discharge and / or rehabilitation and / or surgery. For each evaluation the photograph of the medication must be taken (which will be deprived of all the identifying elements of the patient).
