Objective: Cesarean section is the most frequent obstetrical surgery worldwide, with markedly increasing rates along the last several decades. In this regard, competent surgical technology regarding speed, safety, and efficacy is essential in operating cesarean section. This study was conducted to estimate the efficacy and safety of knotless barbed suture for closure of myometrium during cesarean section compared to conventional method.
Methods: This is retrospective cohort study. Patients who underwent cesarean delivery at Korea University Ansan Hospital, Republic of Korea between August 2018 and December 2019, were reviewed. Main outcome measures were surgical outcomes including uterine closure time, operative time, estimated blood loss and sonographic results of residual myometrial thickness at site of cesarean section scar at 6 to 8 weeks after operation.
Results: Out of total 78 women, 44 women had knotless barbed suture and 34 women had conventional method. The number of previous cesarean section was similar as well as demographic and clinical characteristics between groups. Compared to conventional suture, the suturing time to close the uterine incision were significantly reduced(p=0.012). Operation time, estimated blood loss during operation, hemoglobin difference on third operative day, transfusion and postpartum infection and bleeding demonstrated no significant difference between two groups. At 6 to 8 weeks after operation, transvaginal ultrasound revealed no differences in residual myometrial scar thickness between two groups. Significantly shorter uterine closure time was identified with knotless barbed suture compared to conventional method. There were no increased rate of perioperative complications with knotless barbed suture.
Conclusion: Our results support that the use of knotless barbed suture for cesarean section is comparable to conventional method.
