Efficacy of a non-invasive mechanical wound closure device in post-bariatric plastic surgery: a prospective study

What is it about?

Background Post-bariatric plastic surgery requires optimal wound closure techniques to enhance healing and aesthetic outcomes. Traditional suturing techniques, while effective, may lead to increased tension and scarring. The introduction of non-invasive mechanical wound closure devices offers a promising alternative to traditional sutures. Aim This study aims to evaluate the efficacy of a non-invasive mechanical wound closure device compared to traditional sutures in post-bariatric plastic surgery patients, focusing on healing time, scar qualityand patient satisfaction. Methods A prospective observational study was conducted over three years, including 64 patients undergoing post-bariatric body contouring surgery. Patients were assigned to one of two groups: traditional sutures (n=32) or a non-invasive mechanical closure device (n=32). Wound healing was assessed at 1, 3, and 6 months postoperatively using clinical evaluations and SCAR-Q scores. Complications and patient satisfaction levels were also recorded. Results Patients treated with the mechanical device demonstrated significantly faster healing times (p<0.001), superior SCAR-Q scores (p<0.001), and fewer complications compared to those receiving traditional sutures. At one month, the average healing time was 17.3±2.1 days in the mechanical closure group versus 22.5±2.7 days in the suture group (p=0.002). At three months, SCAR-Q scores were significantly higher in the mechanical closure group (76.4±4.3 versus 68.1±3.9, p<0.001). At six months, the device-treated group reported a complication rate of 3.2% compared to 12.5% in the traditional suture group (p=0.005). Conclusions The study suggests that the non-invasive mechanical closure device is an effective alternative to traditional sutures, offering benefits in wound healing, scar quality and patient satisfaction. Further studies with larger cohorts and longer follow-ups are warranted.
