Objective  To investigate the effect of transvaginal excision of pregnancy lesion in cesarean scar and hysteroplasty in the treatment of cesarean scar pregnancy(CSP).

  Methods  A total of 120 patients with CSP admitted to our hospital were enrolled in the study, and were randomly divided into two groups. The control group was treated with Methotrexate injection and uterine curettage, and the observation group was treated with transvaginal excision of pregnancy lesion in cesarean scar and hysteroplasty. Treatment effects of the two groups were compared.

  Results  There was no significant difference in the operation time between the two groups (P>0.05). The intraoperative blood loss, negative time of β-human chorionic gonadotropin (β-HCG), hospital stay, duration from completion of surgery to first time exhaust, time to first exhaust time after surgery, and time to first ambulance showed significant differences (P < 0.05). After treatment, the blood β-HCG level in the observation group was significantly lower, and the Short-form Quality of Life Scale (SF-36) score was significantly higher than that in the control group (P < 0.05).

  Conclusion  The treatment of uterine scar pregnancy by transvaginal excision of pregnancy lesion in cesarean scar and hysteroplasty is effective.
