Drainage refers to evacuation of an abscess. This can be performed operatively or percutaneously under ultrasound or CT guidance. If the abscess is localized at the level of the skin and underlying superficial tissues, simple removal of sutures or opening of the wound may be sufficient. Percutaneous techniques are preferred when an abscess can be completely drained, and debridement and repair of the anatomic structures are not needed. Factors that may prevent successful source control with percutaneous drainage include diffuse peritonitis, lack of localization of the infectious process, multiple abscesses, anatomic inaccessibility, or the need for surgical debridement.
