Cesarean Section Defect Mechanism and Transvaginal Repair

Background and aims: Cesarean section defect (CSD) can cause abnormal uterine bleeding or impaired fertility, which severely impaire the quality of life in women of pregnant age. For women with moderate or severe CSD, surgery can be performed. The objectives of this study is to compare the efficacy and safety of different suture methods in the treatment of transvaginal diverticulum resection, and the underlying mechanism of CSD occurrence. Methods: The patients diagnosed with CSD will be enrolled and randomizely assigned into suture method A and suture method. The fresh isolated tissue and swab of different sites in genital tract will be collected for NGS, microbiome, metabonomics and proteomics analysis. Hypothesis: The menstruation will be analyzed at different following time. The other clinical information will be also collected, including age at surgery, skin-to skin operative time, estimated blood loss (EBL). The perioperative complications, postoperative hopitalization, cost for hospital stay, blasser/intestinal function recovery will also be compared between two gorup. The outcome of fertility will be compared, such as the premature birth, premature rupture of membranes, and rupture of uterus. The clinical manifestation related to CSD and recurrence will be followed. Besides, the underlying mechanism will be analyzed.
