Abstract
BackgroundThis study evaluates the efficacy of negative-pressure therapy (NPT) in preventing surgical site infections (SSIs) in high-risk surgical oncology patients. MethodsA retrospective analysis of 191 operations for colorectal, pancreatic, or peritoneal surface malignancies was performed. Incisional NPT was used in patients with multiple SSI risk factors. Rates of SSIs were compared with patients treated with a standard sterile dressing (SSD). ResultsNPT was used in 104 patients, whereas SSDs were used in 87 patients. Despite being at an increased risk of SSI, patients treated with NPT developed fewer superficial incisional SSIs compared with SSD patients (6.7% vs 19.5%, P = .015). In a subgroup analysis of clean-contaminated cases, NPT was associated with fewer superficial incisional SSIs (6.0% vs 27.4%, P = .001), fewer total SSIs (16.0% vs 35.5%, P = .011), and fewer wound openings for any reason (16.0% vs 35.5%, P = .011). ConclusionsOur findings suggest that NPT decreases SSIs in high-risk surgical oncology patients.
