Abstract:【Objective】To explore the clinical efficacy of hysteroscopic surgery for type Ⅰ cesarean scar pregnancy (CSP) patients.【Methods】A total of 80 patients with Type Ⅰ CSP admitted to our hospital from January 2015 to October 2019 were selected. Among them,30 patients underwent hysteroscopic resection of scar pregnancy lesions (hysteroscopic group),and 50 patients underwent uterine artery embolization intervention combined with negative pressure suction curettage (curettage group). We compared the intraoperative bleeding volume,surgical time,hospital stay,lump absorption time,and postoperative uterine function related indicators [Menstrual period,menstrual volume,menstrual recovery time,human chorionic gonadotropin (HCG) levels,HCG recovery time,vaginal bleeding time],Psychological changes of pregnant women before and after surgery [Self Rating Anxiety Scale (SAS) score,Self Rating Depression Scale (SDS) score],and the incidence of complications. between the two groups.【Results】The intraoperative bleeding volume,surgical time,hospitalization time,menstrual recovery time,HCG recovery time,and vaginal bleeding time in the hysteroscopy group were significantly lower than those in the curettage group,with statistical significance (P<0.05). The HCG level was significantly lower than that in the curettage group,with statistical significance (P<0.05); The postoperative SAS and SDS scores of the hysteroscopy group were significantly lower than those of the same group before and after the curettage group,and the difference was statistically significant (P<0.05); The incidence of complications in the hysteroscopy group was 10.00%,and there was no statistically significant difference compared to the 14.00% in the curettage group (P>0.05).【Conclusion】Compared with interventional embolization combined with curettage,hysteroscopic surgery has a better therapeutic effect on Type Ⅰ CSP,with fast recovery of uterine function and healthy psychological state,which is worthy of clinical promotion.
