ABSTRACT

OBJECTIVE:To compare the efficacy and safety of levonorgestrel intrauterine system and mifepristone in the treat-ment of perimenopausal dysfunctional uterine bleeding. METHODS:200 patients with perimenopausal dysfunctional uterine bleed-ing were randomly divided into observation group (100 cases) and control group (100 cases). Patients in the observation group placed levonorgestrel intrauterine system (containing levonorgestrel 52 mg),patients in control group received Mifepristone cap-sule 10 mg/d,oral,the treatment course for 2 groups were 3 months. Clinical efficacy,endometrial thickness,menstruation(PBAC score),hemoglobin level before and after treatment and incidence of adverse reaction in 2 groups were observed. RESULTS:After treatment,the total effective rate in observation group was significantly higher than control group,incidence of adverse reactions was significantly lower than control group,the differences were statistically significant(P<0.01). Before treatment,there were no significant differences in the endometrial thickness,PBAC score and hemoglobin level between 2 groups;after treatment,endome-trial thickness and PBAC score were significantly lower than before,and observation group was lower than control group;hemoglo-bin level was significantly higher than before,and observation group was higher than control group,the differences were statistical-ly significant(P<0.01 or P<0.05). CONCLUSIONS:The efficacy and safety of levonorgestrel intrauterine system are significant-ly superior to mifepristone in the treatment of perimenopausal dysfunctional uterine bleeding.
