Is barbed better? Evaluation of triclosan-coated barbed suture on wound complications following emergency laparotomy

Abstract

Introduction Emergent laparotomy is associated with significant wound complications including surgical site infections (SSI) and fascial dehiscence (FD). Triclosan-coated barbed suture (TCB) for fascial closure has been shown to reduce local complications but primarily in elective settings. We sought to evaluate the effect of TCB emergency laparotomy fascial closure on major wound complications. Methods Adult patients undergoing emergency laparotomy were prospectively evaluated over 1-year. Patients were grouped into TCB vs polydioxanone (PDS) for fascial closure. Subanalysis was performed on patients undergoing single-stage laparotomy. Primary outcomes were SSI and FD. Multivariate analysis identified independent factors associated with SSI and FD. Results Of the 206 laparotomies, 73 (35%) were closed with TCB and 133 (65%) were closed with PDS. Trauma was the reason for laparotomy in 73% of cases; damage control laparotomy (DCL) was performed in 27% of cases. The overall rate of SSI and FD was 18% and 10%, respectively. Operative strategy was similar between groups, including DCL, wound vac use, skin closure, and blood products. SSI events trended lower with TCB vs PDS closure (11% vs. 21%; p = .07), and FD was significantly lower with TCB versus PDS (4% vs. 14%; p < .05, Fig 1). Subanalysis of trauma and non-trauma cases showed no difference in SSI or FD. Multivariable analysis found that TCB decreased the likelihood of FD (OR .07; p < .05, Fig 2) following emergency laparotomy. Increased odds of FD were seen in DCL (OR 3.1; p < 0.05). Conclusions Emergency laparotomy fascial closure with TCB showed significantly decreased rates of FD compared to closure with PDS, and a strong trend toward lower SSI events. TCB was independently associated with decreased FD rates after emergency laparotomy.
