Brief Summary

Cesarean scar diverticula (CSD) is a novel recognized cause of postmenstrual abnormal uterine bleeding in women. No clinical guidelines have been issued for the management of CSD. The investigators have previously demonstrated that vaginal repair of CSD was an relative effective treatment of CSD. However, only 28.2% of the CSD patients normalized to less than 7 days of menstruation, whereas 51.2% of women had 7 to 10 days of menstruation at 6 months post vaginal repair. Postoperative menstruation may contribute to surgical site infections, which may subsequently affect the healing of uterine scars. Treatment CSD patients with gonadotropin-releasing hormone agonist (GnRHa) may has the potential to improve therapeutic effects of vaginal repair. Therefore, the current multiple-center randomized controlled trial was designed to evaluate whether the application of GnRHa in combination with vaginal repair could achieve better clinical effects than those achieved by vaginal CSD repair alone.

Secondary Outcomes (3)

  • the length of CSD (mm)

    6 months after vaginal repair of CSD

  • the width of CSD (mm)

Study Arms (2)

VR + GnRHa

EXPERIMENTAL

CSD patients were treated with vaginal repair of CSD in combination with GnRHa (Zoladex, 3.6 mg, AstraZeneca, Macclesfield, United Kingdom) as a subcutaneous injection (abbreviated as VR + GnRHa). In the group of VR + GnRHa, 2 doses of GnRHa were administered. The first dose was injected at the time of hysteroscopy examination, and the second dose was administered one day after the VR surgical procedure. The detailed procedure of VR has been described in our previous study (Zhou et al., 2016).

VR

PLACEBO COMPARATOR

CSD patients were treated with vaginal repair of CSD in combination with 0.01 ml saline as a subcutaneous injection (abbreviated as VR). In the group of VR, 2 doses of saline were administered. The first dose was injected at the time of hysteroscopy examination, and the second dose was administered one day after the VR surgical procedure. The detailed procedure of VR has been described in our previous study (Zhou et al., 2016).

Procedure: Vaginal repair of CSD

Interventions

GnRHaDRUG

Two doses of GnRHa were administered by subcutaneous injection. The first dose was injected at the time of hysteroscopy examination, and the second dose was administered one day after the VR surgical procedure.

Also known as: Zoladex, 3.6 mg, AstraZeneca, Macclesfield, United Kingdom
VR + GnRHa

The procedure of vaginal repair of CSD was shown as following. The bladder was dissected away carefully from the uterus toward the abdominal cavity until the peritoneum was reached. The CSD tissue was cut to the normal healthy muscle after the abdominal cavity had been entered, and the lower uterine segments had been completely exposed. A double layer of 1-0 absorbable interrupted sutures was used to close the incisions.
