An observational study in Post Cesarean Scar Defect and Hysteroscopy, sponsored by First Affiliated Hospital, Sun Yat-Sen University. Status unknown at 2 sites in China. Open to female participants aged 20 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2019-09-20.
Sponsored by First Affiliated Hospital, Sun Yat-Sen University · Observational
The study is to compare hysteroscopic repair and transvaginal intervention for correcting uterine defect in patients with post cesarean scar defect (PCSD) and the reproductive prognosis.
Post cesarean scar defect (PCSD), refers the lower uterine segment form a reservoir-like pouch during healing process after transverse lower uterine segment cesarean section connected with uterine cavity. The pouch has a valve-like effect, obstructing blood drainage and accumulating blood in depression. These causes may lead to a variety of gynecological disturbances, secondary dysmenorrheal and infertility. Some patients can occur some serious obstetric complications, such as cesarean scar pregnancy and even the rupture of uterus during a subsequent pregnancy. At present, the causes and mechanisms of PCSD are not clear, diagnosis and treatment are not uniform. Surgical methods include abdominal surgery, laparoscopic surgery, transvaginal surgery, hysteroscopic surgery, hysteroscopic with laparoscopic surgery and so on. Hysteroscopic and transvaginal surgery to treating PCSD both are minimally invasive and feasible surgical approach. However, hysteroscopic surgery and transvaginal surgery have not been compared for correcting the uterine defect in patients with PCSD before.

Exclusion Criteria:
patients with post cesarean scar defect
Procedure: hysteroscpy
patients with post cesarean scar defect
Number of Participants with a less postoperative menstruation
Follow-up carried out 6 months after the initial operation, using the following criteria to evaluate curative effect: Cure: menstrual duration was shortened to no more than 7 days and TVU showed no liquid dark area in scar of lower uterine segment; Improvement: menstrual duration was reduced by more than 2 days, but menstrual duration was still longer than 7days and TVU showed the liquid dark area in lower segment of uterus disappeared or narrowed. Failure: menstrual duration was reduced by less than 2 days or had no obvious change, and TVU showed the liquid dark area in lower segment of uterus did not narrow. Efficiency rate = cure rate + improvement rate.
Time frame: 6 months
Number of Participants being a pregnant
Follow-up carried out 1 year after the initial operation, postoperative pregnancy with a history of infertility preoperatively
Time frame: 1 year
Plan to share: Yes
