ABSTRACT
Objective To evaluate the efficacy of levonorgestrel-releasing intrauterine system(LNGIUS) in the treatment of endometriosis. Methods Fifty-three patients suffering from endometriosis were placed LNG-IUS in uterine cavity after menstruation. The efficacy 3,6,12 months after LNG-IUS placement was observed and compared. Results The scores of dysmenorrhea, deep dyspareunia, menstrual anus pain 3,6,12 months after LNG-IUS placement were lower than those before LNG-IUS placement (P ＜ 0.05 ).CA125 [(21.8±12.5) kU/L]and destradiol [(78.8±45.5)ng/L] 12 months after LNG-IUS placement were improved than those before LNG-IUS placement and 3,6 months after LNG-IUS placement [CA 125:(36.3±17.5), (33.5±15.6), (28.2 ± 11.7) kU/L,destradiol: (40.4 ± 28.6), (42.5 ± 31.5), (56.5 ± 36.2) ng/L](P ＜ 0.05 ). The menstrual blood volume was less 6,12 months after LNG-IUS placement than that before LNG-IUS placement (P＜0.05), and the quality of life was improved( P ＜ 0.05 ). Conclusion LNG-IUS can be safe and effective treatment of patients with endometriosis, and less side effects.
