PURPOSE: The aim of this paper was to evaluate the effectiveness in day clinics of microwave endometrial ablation (MEA) on transcervical microwave myolysis for patients with menorrhagia caused by submucosal myomas.
MATERIALS AND METHODS: Thirty-five outpatients (average age 44.8 ± 5.2 years (mean ± SD), range 34-58) with a single submucosal myoma that was 4-7 cm (5.5 ± 2.1 cm) in size underwent MEA with transcervical microwave myolysis using a specifically developed transabdominal ultrasound probe attachment for transcervical puncture. Primary outcomes were the changes in the blood haemoglobin level and the volume of myoma before and after the treatment. Secondary outcomes were the improvement in menorrhagia and satisfaction after the operation, assessed by visual analogue scale (VAS).
RESULTS: The mean operation time was 27.9 ± 13.6 min. The myomas had shrunk by 56.2% at 3 months and 73.8% at ≥6 months after the operation. Blood haemoglobin levels had increased significantly at 3 months (10.2 ± 2.0 vs. 12.7 ± 1.2, p < 0.001). The average VAS assessment of menstrual bleeding had decreased to 1.7 ± 1.7 at 3 months after the operation (preoperative VAS = 10). The average VAS score for feelings of satisfaction 3 months after the operation was 9.8 ± 0.5 (full score = 10).
CONCLUSIONS: MEA with transcervical microwave myolysis is a feasible and effective procedure in a day surgery clinic for menorrhagia caused by submucosal myomas. The procedure may be an alternative to hysterectomy for menorrhagia caused by submucosal myomas in women during the perimenopausal period.
