Introduction:
The aim of this randomized control trial was to compare the operative data and the early postoperative outcomes of cesarean sections in which the uterine incision was closed with a barbed suture (STRATAFIX™ Spiral PDO Knotless Tissue Control Device, SXPD2B405, Ethicon Inc.) with those of cesarean sections in which the uterine incision was closed with a conventional smooth suture (VICRYL™; Ethicon Inc.).
Materials And Methods:
One hundred pregnant patients were randomized in a 1:1 ratio to the Stratafix group or the Vicryl group. The uterine incision was closed by two layers of sutures in both groups. In the Vicryl group, the first layer was continuous and the second layer was interrupted. In the Stratafix group, both layers were continuous.
Results:
The uterine closure time was significantly lower in the Stratafix group (224 ± 46 versus 343 ± 75 s, p < .001). Operative time was comparable between both groups. Twelve patients in the Vicryl group and two patients in the Stratafix group required additional sutures to achieve hemostasis (p value = .009). The mean blood loss during closure of uterine incision and mean hospital stay were lower in the Stratafix group but these differences failed to reach statistical significance.
Conclusion:
The use of barbed suture for uterine incision closure at cesarean section is associated with shorter uterine closure time and similar early perioperative complications compared with conventional smooth suture. The difference between both groups in the technique of suturing the second layer of the uterine incision may be the cause of the reduction in the uterine closure time and the need for additional sutures to achieve hemostasis during suturing the uterine incision with a barbed suture. Further, well designed randomized controlled trials should be conducted to investigate the association between the type of suture (barbed or conventional smooth) and remote complications of cesarean section (infertility, pelvic pain, abnormal placentation and rupture uterus).
