Objective To compare the clinical efficacy and longterm outcomes of hysteroscopic surgery, focused ultrasound ablation (FUA) combined with hysteroscopic surgery, uterine artery embolization (UAE) combined with suction curettage in the treatment of cesarean scar pregnancy of type Ⅰ and typeⅡ. Methods The clinical data and long-term outcomes of 90 patients diagnosed as type Ⅰ and type Ⅱ CSP in Suining Central Hospital from June 2016 to May 2020 were retrospectively analyzed. Results Among the 90 cases, 32 cases received hysteroscopic surgery alone, 42 cases received FUA combined with hysteroscopic surgery, and 16 cases received UAE combined with curettage under guidance of hysteroscopy. The bleeding during the procedure of hysteroscopic surgery in the three groups was 72.50±52.49mL, 34.64±28.93mL, and 56.56±46.03mL respectively. A significant difference was observed among the three groups (P＜0.05). The rates with no significant changes in postoperative menstruation in the three groups were 43.8%, 81.0%, and 31.3% respectively. A significant difference was observed among the three groups (P＜0.05). The VAS pain score in the patients treated with FUA treatment was significantly lower than that of patients treated with UAE (P＜0.05). No major complication was observed in any patient in this study. Conclusion Either hysteroscopic surgery, FUA combined with hysteroscopic surgery, and UAE combined with hysteroscopic surgery can be safely and effectively used in the treatment of typeⅠand type ⅡCSP. However, it seems that FUA combined with hysteroscopic surgery had less bleeding and pain and better longterm menstrual recovery.
