This study found that the use of prophylactic sNPWT PICO dressing for closed surgical incisions following IH repair significantly reduces the overall incidence of SSOs and wound infections at 30 days postoperatively, showing promising efficacy in preventing SSos.
Objective: A randomized controlled trial (RCT) was undertaken to evaluate whether the prophylactic application of a specific single-use negative pressure (sNPWT) dressing on closed surgical incisions after incisional hernia (IH) repair decreases the risk of surgical site occurrences (SSOs) and the length of stay. Background: The sNPWT dressings have been associated to several advantages like cost savings and prevention of SSOs like seroma, hematoma, dehiscence, or wound infection (SSI) in closed surgical incisions. But this beneficious effect has not been previously studied in cases of close wounds after abdominal wall hernia repairs. Methods: An RCT was undertaken between May 2017 and January 2020 (ClinicalTrials.gov registration number NCT03576222). Participating patients, with IH type W2 or W3 according to European Hernia Society classification, were randomly assigned to receive intraoperatively either the sNPWT (PICO)(72 patients) or a conventional dressing at the end of the hernia repair (74 patients). The primary endpoint was the development of SSOs during the first 30 days after hernia repair. The secondary endpoint included length of hospital stay. Statistical analysis was performed using IBM SPSS Statistics Version 23.0. Results: At 30 days postoperatively, there was significatively higher incidence of SSOs in the control group compared to the treatment group (29.8% vs 16.6%, P < 0.042). There was no SSI in the treatment group and 6 cases in the control group (0% vs 8%, P < 0.002). No significant differences regarding seroma, hematoma, wound dehiscence, and length of stay were observed between the groups. Conclusion: The use of prophylactic sNPWT PICO dressing for closed surgical incisions following IH repair reduces significatively the overall incidence of SSOs and the SSI at 30 days postoperatively.
