Initiated in the orthopaedic literature, a new technique of wound dressing has been described to reduce SSI. Incisional negative pressure wound therapy (NPWT) using devices such as the Prevena™ involves applying a wound vacuum sponge over a standard wound closure (including fascial closure and skin closure with staples). The incisional NPWT dressing is then left in place for 5 to 7 days before removal. A recent retrospective study by Bonds et al. described the ability of incisional NPWT to reduce SSI rates in open colorectal surgery from 29.3-12.5%.
