    Abstract:
    OBJECTIVE: With the incidence of cesarean scar pregnancy (CSP) rising, the reports of serious adverse outcomes of it have increased gradually. The management of CSP remains an inadequately explored clinical field, and there is no consensus on it presently. The present study was performed to investigate the efficacy and safety of operative hysteroscopy in the diagnosis and treatment of CSP. MATERIALS AND METHODS: Forty-four patients with CSP underwent operative hysteroscopy for removal of scar ectopic pregnancy in our institution. Among them, hysteroscopy was combined with laparoscopy in two patients, three cases with massive hemorrhage were pretreated with bilateral uterine artery embolization before hysteroscopic surgery, and four patients were pretreated with mifepristone (200 mg for 3 days) and methotrexate (25 mg for 2 days). Clinical data, serum β-human chorionic gonadotropin, myometrial thickness, residual conceptus, cesarean scar defect, operation time, blood loss, and hospital stay were recorded. RESULTS: All of the ectopic gestations were removed entirely by operative hysteroscopy. Mean operation time was 34.8±16.5 minutes (range 20-120 minutes), and mean blood loss was 35.3±24.4 mL (range 5-100 mL). The mean hospital stay was 5.0±3.01 days (range 1-19 days). Cesarean scar defect could be diagnosed in 70% (31/44) of patients, while in 20/32 cases (63%), a conceptus remained after uterine curettage only was performed. CONCLUSION: Operative hysteroscopy might be recommended as a first-line treatment modality for patients with a cesarean scar ectopic pregnancy, especially when myometrium thickness between bladder and gestational sac is more than 3 mm.
