Abstract
Objective:To explore the effect of different suture methods in parturients who underwent cesarean section again,to provide a theoretical basis for preventing the formation of previous cesarean scar defect(PCSD).Method:A total of 330 parturients admitted to Department of Obstetrics and Gynecology,the Affiliated Hospital of Xuzhou Medical University from October 2020 to October 2022 were randomly divided into 3 groups:the control group(with simple continuous suture),the scar resection group(with scar tissue resection plus double-layer continuous suture),and the reinforcement suture group(with reinforcement suture for the inferior anterior uterine wall muscle defect),110 cases in each roup.The perioperative indexes,menoxenia and PCSD formation were compared among the three groups.Result:There were no significant differences in intraoperative blood loss,operation time,urinary tube extraction time,anal exhaust time,postpartum lochia rubra duration and hospital stay among the three groups(P>0.05).The rates of menoxenia and PCSD formation in scar resection group and reinforcement suture group were significantly lower than those in control group,the residual myometrium thickness were greater than those in control group,and volume were significantly smaller than those in control group,the differences were statistically significant(P<0.05).There were no significant differences in the rates of menoxenia and PCSD formation,and residual myometrium thickness and volume between the scar resection group and the reinforcement suture group(P>0.05).Conclusion:Scar tissue resection plus double-layer continuous suture or reinforcement suture for the inferior anterior uterine wall muscle defect can effectively prevent the formation of PCSD,reduce the severity of PCSD,and reduce the incidence of postoperative menoxenia.关键词
