Barbed Versus Conventional Suture forUterine Repair During Caesarean Section: A Randomized Controlled Study

Abstract Objective This study sought to compare the short-term outcome of uterine incision repair during a Caesarean section (CS) using a bidirectional knotless barbed suture versus polyglactin suture. Methods A randomized controlled trial was conducted at a university hospital. Participants undergoing a CS were randomized for uterine incision closure by bidirectional knotless barbed suture (group A) or polyglactin (group B). The primary outcome was the time needed to repair the uterine incision. The analysis was by intent to treat. A sample size of 35 per group (n = 70) was planned to detect a 30% reduction in uterine repair time (Canadian Task Force Classification I). Results From July 2016 through October 2017, 150 women were screened, and 70 were statistically analyzed: group A (n = 35) and group B (n = 35). Time to complete uterine incision repair was 308 ± 57 seconds for group A and 411 ± 74 seconds for group B ( P P = 0.64) was not significantly different between groups A and B, respectively. Conclusion Repair of the CS uterine incision with barbed suture compared with polyglactin suture reduces suturing time.
