Abstract

BACKGROUND Surgical site infection (SSI) is one of the most frequent complications in colorectal surgery. It is diagnosed in 10 - 20% of colorectal procedures. Negative Pressure Wound Therapy (NPWT) has shown efficacy in the treatment of chronic and traumatic wounds, wound dehiscence, flaps and grafts. The main objective of this study is to assess NPWT in the prevention of SSI in colorectal surgery. Hospital stay reduction and SSI risk factors are secondary objectives. METHODS We present a prospective case-control study including 80 patients after a colorectal diagnosis and surgical procedure (elective and non-elective) in 2017. Forty patients were treated with prevention NPWT for one week. Forty patients were treated according to the standard postoperative surgical wound care protocol. RESULTS No significant differences were found in demographic variables, comorbidities, surgical approach, elective or non-elective surgery, mechanical bowel preparation and surgical procedure. Three patients has SSI in the NPWT group (8%) (95%CI 0 - 17.5). Ten patients presented SSI in the control group (25%) (95%CI 12.5 - 37.5) (p=0.034); OR 0.7 (95%CI 0.006-0.964). Hospital stay in the NPWT group was 8 days versus 12 days in the non-NPWT group (p=0.22). In the multivariate analysis, mechanical bowel preparation was found to be the only risk factor for SSI (p=0.047; OR: 0.8, CI 0.45-0.93). CONCLUSIONS NPWT is a useful SSI prevention treatment in colorectal surgery.
