BackgroundSurgical site infection after surgery for gynecologic cancer increases morbidity. Prophylactic closed incision negative pressure therapy has shown promise in reducing infectious wound complications across many surgical disciplines.ObjectiveThis study aimed to determine whether closed incision negative pressure therapy is associated with reduced surgical site infections in gynecologic oncology patients undergoing laparotomy compared with standard dressings.Study DesignThis was a retrospective case-control study of patients undergoing laparotomy for known or suspected gynecologic cancer from Jan. 1, 2017, to Feb. 1, 2020. Patients were matched in a 1:3 ratio (closed incision negative pressure therapy to standard dressing) by body mass index, age, diabetes, bowel surgery, smoking, and steroid use. Surgical site infection was defined according to the Centers for Disease Control and Prevention. Multivariable logistic regression using backward selection was performed.ResultsOf the 1223 eligible patients undergoing laparotomy, 64 (5.2%) received closed incision negative pressure therapy dressings and were matched to 192 (15.7%) controls. There were no differences in medical comorbidities (P>.05), site or stage of malignancy (P>.05), duration of surgery (P=.82), or surgical procedures (P>.05). Use of closed incision negative pressure therapy was associated with reduction in all adverse wound outcomes (20.3% vs 40.1%; P<.001). In particular, closed incision negative pressure therapy was associated with a significant reduction in both superficial incisional surgical site infections (9.4% vs 29.7%; P<.001) and deep incisional surgical site infections (0.0% vs 6.8%; P=.04). In multivariable analysis, use of closed incision negative pressure therapy was associated with significant reduction in the incidence of superficial incisional infections alone (odds ratio, 0.29; 95% confidence interval, 0.12-0.73; P=.008) and both superficial and deep incisional infections (odds ratio, 0.29; 95% confidence interval, 0.12-0.71; P=.007).ConclusionUse of prophylactic closed incision negative pressure therapy after laparotomy in gynecologic oncology patients was found to be associated with reduced superficial incisional and deep incisional infections compared with standard dressings. Furthermore, closed incision negative pressure therapy was associated with reduction in all other adverse wound outcomes. Closed incision negative pressure therapy may be considered for surgical site infection prevention in high-risk gynecologic oncology patients undergoing laparotomy.Copyright © 2020 Elsevier Inc.
