# Efficacy of knotless barbed versus conventional sutures for uterine closure during cesarean section: A prospective comparative study

## TL;DR

This study compares knotless barbed sutures with conventional sutures for uterine closure during cesarean sections, finding that the knotless option is faster and more efficient.

## Contribution

The study provides empirical evidence on the operational efficiency and hemostatic benefits of knotless barbed sutures in uterine closure.

## Key findings

- Knotless barbed sutures reduced uterine incision closure time and total closure time significantly.
- Knotless barbed sutures required fewer extra hemostatic sutures.
- Knotless barbed sutures resulted in thicker scars at 6 weeks post-surgery.

## Abstract

Cesarean section is a typical surgical practice whereby a good uterine closure is essential for maternal outcomes. Conventional
suturing involves knot-tying, which may take long and may weaken the integrity of tissues. This study involves a comparison between
knotless barbed sutures (KBS) and the use of conventional sutures (CS) to close the uterus in case of cesarean delivery. In an 80-women
prospective comparative trial, KBS decreased the uterine incision closure time (8.58 ± 1.18 min vs. 10.18 ± 1.81 min,
p=0.002) and total closure time (27.77 ± 4.73 min vs. 30.95 ± 3.08 min, p=0.001) significantly. The extra hemostatic
sutures required were significantly reduced in KBS (5% vs. 27.5, p=0.006). The thickness of the scar at 6 weeks (4.23 ± 0.90 mm
vs. 3.54 ± 0.60 mm, p<0.001), was larger in the KBS. Knotless barbed sutures have considerable benefits on efficiency of
operations, hemostasis and tissue healing of cesarean uterine closure.
