Closed Incision Negative Pressure Wound Therapy for the Prevention of Surgical Site Infections in Abdominal Surgery — CISSI  

Surgical Wound Infection Clinical Trial

Official title:
Closed Incision Negative Pressure Wound Therapy for the Prevention of Surgical Site Infections in Abdominal Surgery - A Multicenter Randomized Controlled Trial

Clinical Trial Summary

Surgical site infections (SSI) are a frequent complication in abdominal surgery. SSI lead to worse outcomes for the affected patients and significantly higher healthcare costs. Closed incision negative pressure wound therapy (ciNPWT) consists of a non-invasive, vacuum-assisted system that applies negative pressure to closed surgical incisions. It is currently unclear, if ciNPWT reduces SSI in patients undergoing abdominal surgery. This trial will investigate the effect of ciNPWT on SSI in abdominal surgery.

Clinical Trial Description

Background: Surgical site infections (SSI) are a frequent complication after abdominal surgery and are associated with increased morbidity and mortality, longer hospital stay, and significantly increased healthcare costs. Closed incision negative pressure wound therapy (ciNPWT) is a non-invasive, vacuum-assisted system that applies negative pressure to closed surgical incisions. Recent meta-analyses suggest that ciNPWT reduces the risk of SSI in abdominal surgery. However, based on the available randomized controlled trials (RCT), the evidence for the effect of ciNPWT on SSI in abdominal surgery is insufficient. Rationale: Considering the frequent occurrence of SSI in abdominal surgery, associated worse outcomes, and insufficient evidence, an adequately powered, robust RCT investigating the effect of ciNPWT on SSI in elective and emergency abdominal surgery is warranted. Provided that ciNPWT significantly reduces the incidence of SSI, this adjunct to surgical therapy has the potential to fundamentally improve patient outcomes in abdominal surgery. Aim of the trial: To investigate the effect of ciNPWT on superficial and deep SSI in patients undergoing elective or emergency abdominal surgery by laparotomy. Methodology: Multicenter, open-label, two arm, parallel group RCT. Patients undergoing elective or emergency laparotomy will be enrolled. During surgery, participants will be randomized in a 1:1 ratio to the ciNPWT (treatment) or standard dressing (control) group. After the completion of abdominal surgery and standardized skin closure with staples, either ciNPWT or standard dry dressings will be applied. Other than the study procedure, participants in both groups will be treated the same according to the current standard of care at the participating centers. Data collection will be carried out during the subsequent hospital stay and at 30 (+/- 7) days postoperatively. Hypothesis: The investigators hypothesize that ciNPWT will significantly reduce the incidence of superficial and deep SSI in patients undergoing laparotomy. ;
