A Randomized Controlled Study of Uterine Incision Diverticulum Repair vs. no Repair During Second/Third Cesarean Section
- Conditions
- Cesarean Scar Diverticulum
- Interventions
- Procedure: Repair of uterine cicatricial diverticulum
- Registration Number
- NCT06612957
- Lead Sponsor
- Shanghai First Maternal and Infant Health Hospital affiliated to Tongji University Medical School
- Brief Summary
The goal of this study is to assess the efficacy and safety of uterine incision diverticulum repair during repeat cesarean section.The main questions it aims to answer are:
* Can this surgical method improve the symptom of menorrhagia？
* Is this procedure safe？ Researchers will compare experimental group(Cesarean section + diverticulum repair group) to control group(Conventional cesarean section group) to see if this surgical method works to treat or improve menorrhagia.
Participants will:
* randomly assigned 1:1 to the experimental group（repairing uterine diverticula during cesarean section) and the control group （Routine cesarean section without repairing the uterine incision diverticulum）
* visit the hospital 42 days after surgery
* followed up by telephone 6-12 months after surgery

Group Intervention Description Cesarean Section + Uterine Diverticulum Repair Group Repair of uterine cicatricial diverticulum The original skin incision is used as the surgical incision. Tissues are sequentially separated until reaching the uterus. The original uterine incision'supper edge is used as the surgical incision for this procedure. The bladder is pushed down to fully expose the lower segment of the uterus. After the complete delivery of the fetus and placenta, the placental tissues are thoroughly cleaned, and the uterine scar diverticulum tissue in the lower segment is trimmed down to the original incision edge, making the lower edge of the incision normal uterine muscle tissue. The trimmed uterine scar diverticulum tissue is sent for pathological examination.
