摘　　要：BACKGROUND Microwave endometrial ablation(MEA)is a minimally invasive treatment for menorrhagia.It has been covered by the national insurance in Japan since April 2012,and its demand has been increasing as the importance of women’s health has advanced in society.AIM To examine the efficacy of MEA as a treatment option for menorrhagia.METHODS In this study,we retrospectively analyzed 76 patients who underwent MEA between January 2016 and March 2020 in our department.MEA was performed in the lithotomy position,under general anesthesia,and with transabdominal ultrasound guidance,including the entire endometrial circumference while confirming endometrial coagulation.The Microtaze AFM-712 and the Sounding Applicator CSA-40CBL-1006200C were used for MEA,and the endometrium was ablated using a Microtaze output of 70 W and coagulation energization time of 50 s per cycle.The visual analog scale(VAS)was used to evaluate menorrhagia,menstrual pain,and treatment satisfaction.Additionally,the hemoglobin(Hb)levels before and after MEA and associated complications were investigated.RESULTS The average age of the patients was 44.8±4.0 years.While 14 patients had functional menorrhagia,62 had organic menorrhagia,of whom 14 had endometrial polyps,40 had uterine fibroids,and 8 had adenomyosis.The VAS score before MEA and 3 and 6 mo after the procedure were 10,1.3±1.3,and 1.3±1.3,respectively,for menorrhagia and 10,1.3±1.8,and 1.3±1.8,respectively,for menstrual pain,both showing improvements(P<0.001).The MEA Hb level significantly improved from 9.2±4.2 g/dL before MEA to 13.4±1.2 g/dL after MEA(P=0.003).Treatment satisfaction was high,with a VAS score of 9.6±0.7.Endometritis was observed in one patient after surgery and was treated with antibiotics.CONCLUSION MEA is a safe and effective treatment for menorrhagia.
