Study On The Prevention Of Uterine Scar Diverticulum By Trimming The Original Thin Scar Tissue And Double Suture Incision During The Second Cesarean Section

Objective:To investigate the effect of trimming the original uterine scar tissue and making double incision suture to prevent the occurrence of postoperative uterine scar diverticulum during the second cesarean section.Methods:In this study,120 patients who were admitted to the Department of Obstetrics in the Affiliated People’s Hospital of Nanchang University from January 2019 to January 2020 and underwent elective secondary cesarean section were selected.A total of 101 cases were left after random grouping and the lost subjects were removed.They were divided into study group(uterine repair group,52 cases)and control group(routine operation group,49 cases).All subjects were followed up regularly for 12 months.The operative time,intraoperative blood loss,postoperative hospitalization time,peripheral organ injury,anal exhaust time,duration of lochia rubra,and chronic pelvic pain were counted in the two groups.Menstrual changes were tracked and the incidence of uterine scar diverticulum after cesarean section was statistically analyzed by transvaginal color ultrasound.Results:All 101 patients were followed up for 12 months after surgery.Both groups of subjects recovered well after surgery.(1)Compared with the control group,there were no significant differences in operative time,intraoperative blood loss,anal exhaust time,peripheral organ injury,postoperative hospital stay and chronic pelvic pain between the study group and the control group(P > 0.05).(2)Comparison between the study group and the control group in terms of operative time,intraoperative blood loss,anal exhaust time,peripheral organ injury,postoperative hospital stay,(2)postoperative lochia rubra duration between the two groups of subjects,the study group(8.75±2.54)d VS the control group(12.85±2.78)d,(P < 0.05),the difference was statistically significant.The duration of lochia rubra was significantly shortened in the study group.(3)Twelve months after surgery,the incidence of CSD in the control group(6cases /12.2%)vs.the study group(1 case /1.9%)was found by color vaginal ultrasound,with a statistically significant difference(P < 0.05).The number of uterine scar diverticulum in the study group was less than that in the control group.:In the second cesarean section,triming the thin tissue of the original scar and double-layer suture of the incision can effectively increase the thickness of the muscle layer at the scar,reduce the incidence of CSD,and significantly shorten the duration of lochia rubra after cesarean section.Reduce the complications of the operation and improve the quality of life.
