BACKGROUND: We hypothesized that the universal adoption of closed wounds with negative pressure wound therapy (NPWT) in emergency general surgery patients would result in low superficial surgical infection (SSI) rates. STUDY DESIGN: We performed a retrospective observational study using primary wound closure with external NPWT, from May 2017 to May 2018. Patients with active soft tissue infection of the abdominal wall were excluded. Data were analyzed by Fisher's exact tests and Wilcoxon-Mann-Whitney tests, with significance is set at a value of p < 0.05. RESULTS: Eighty-five patients (53% female) with a median age of 65 years (range 19 to 98 years) underwent laparotomies. Four patients were excluded for active soft tissue infection. Wounds were classified as dirty (n = 18), contaminated (n = 52), and clean contaminated (n = 11). Median BMI was 27 kg/m(2) (interquartile range [IQR] 23.4 to 33.0 kg/m(2)). Median antibiotic therapy was 4 days (IQR 1 to 7 days). Twenty-six patients had open abdomen management. Patient follow-up was a median of 20 days (range 14 to 120 days). Six patients (7%) developed superficial SSI requiring conversion to open wound management. No patients developed fascial dehiscence. There were no statistically significant associations between SSI and wound class (p = 0.072), antibiotic duration (p = 0.702), open abdomen management, or preoperative risk factors (p < 0.1). Overall morbidity was 38% and mortality was 6%. CONCLUSIONS: Primary closure of high risk incisions combined with NPWT is associated with acceptably low SSI rates. Due to the low morbidity and decreased cost associated with this technique, primary closure with NPWT should replace open wound management in the emergency general surgery population.
