Abstract: Objective To review the clinical data about patients with typeⅢcesarean scar pregnancy (CSP) and explore the clinical value of laparoscopic and hysteroscopic gynecological surgery. Methods Totally 66 patients with type Ⅲ CSP who were treated in our hospital from June 2013 to June 2018 were selected as research subjects. According to the operation methods, they were divided into three groups, combined laparoscopic and hysteroscopic gynecological surgery group (group A, n=31), laparoscopic surgery alone group (group B, n=23) and transvaginal surgery group (group C, n=12). The operative and therapeutic indicators were analyzed and compared. Results The number of patients in group A underwent uterine artery embolization or uterine artery occlusion was less than that in group B and group C 14 cases (45.2%) vs 17 cases (73.9%) and 10 cases (83.3%), P=0.024. No patient transferred to other operation in group A, but 2 cases in group B and 2 cases in group C had transferred to other operation. The treatment costs of group C was significantly less than that of group A and group B (13 820.5±2 281.3) yuan vs (19 602.9±3 630.7) yuan and (21 471.1±4 421.8) yuan, P＜ 0.001. There was no significant difference in other indicators. Conclusion Combined laparoscopic and hysteroscopic surgery for treatment of typeⅢCSP can reduce the rate of uterine artery embolization /occlusion, facilitate the evaluation of the disease, reduce the risk of surgery and ensure the efficacy.
