Does prophylactic negative pressure wound therapy prevent surgical site infection in abdominal surgery?

Objective: To determine if prophylactic negative pressure wound therapy (pNPWT) allows for the prevention of surgical site infections (SSIs) in abdominal surgery. Method: A non-systematic review assessing the evidence was conducted in 2020. Results: Retrospectve studies comparing patients with pNPWT with patients receiving standard wound dressing after abdominal surgery showed encouragning results in favour of pNPWT for reducing the incidence of SSIs, but randomised controlled trials have so far reported mixed results. Conclusion: New randomised controlled trials including a sufficient number of patients at risk of SSIs are needed for confirming the results of non-interventional studies.
