Objective:To investigate the effect of hysteroscopic incision and excision of uterine adhesion on endometrial receptiv-ity.Methods:60 patients with moderate and severe uterine adhesions were divided into the study group and the control group according to the different treatment methods,30 cases in each group.Patients in the study group were treated we used a plasma electrode needle under hysteroscopy to just strip away adhesion.Whereas,the control group additionally required the use of an electrocution ring removal for scar excision.Endometrial receptivity indexes were evaluated by transvaginal ultrasound.Follow-up pregnancy outcome.Results:En-dometrial vascular index(VI)and vascular blood flow index(VFI)were higher in the study group than in the control group(P＜0.05).There was no statistically significant difference between the two group in intraoperative situation,post-operative hystero-scopic evaluation,menstrual recovery,endometrial type,blood flow pattern,endometrial thickness(ED),endometrial volume(EV)and blood flow index(FI)(P＞0.05),and no statistically dignificant difference in pregnancy outcome(P＞0.05).Conclusion:Under hysteroscopy,simple plasma electrode needle incision and electrocution ring removal could effectively restore uterine cavity morphology.The former is simpler than the latter,and has less influence on the blood flow parameters in endometrial receptivity.
