Summary

Cesarean section scar defect (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. The previous research suggested that the occurrence of CSD may be related to the aging phenotype of the myometrium. Metformin, as a classic diabetes treatment drug, has an important position in anti-aging therapy. Therefore, the randomized study was designed to evaluate whether the application of metformin in combination with vaginal repair could achieve better clinical effects than those achieved by vaginal CSD repair alone.

PROCEDURE

Vaginal repair

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.
