RESUMO
OBJECTIVE: To evaluate long term effect and related factors in patients with menorrhagia treated by microwave endometrial ablation (MEA). METHODS: Total of 334 women with menorrhagia were treated by MEA, the range of age was from 29 to 59 years old. Among them, 59 cases were complicated by adenomyosis. All the patients were followed up on the change of menstrual cycle, the amount of flow, improvement of anaemia and complication. Fifty-three women underwent outpatient diagnostic hysteroscopy, the biopsy tissue was taken from the endometrium for histopathological examination. The mean duration of follow-up was 64.7 months (3 - 96 months). RESULTS: The overall curative rate was 91.3% (305/334), of which amenorrhea rate was 49.7% (166/334), menstruation reduction rate was 41.6% (139/334) ; 71.1% (140/197) of the cases who previously had dysmenorrhea had relieved their pelvic pain and the satisfactory rate was 91.9% (307/334). Among patients > 40 years, 92.9% (196/211) of operation effective rate, 93.8% (198/211) of satisfactory rate and 64.9% (137/211) of amenorrhea rate were obtained, while patients
