Microwave endometrial ablation for menorrhagia.

Sixteen women requesting surgical treatment of menorrhagia were recruited for a study on microwave endometrial ablation. The mean age at treatment was 41.4 years and all patients had completed their family and were pre-menopausal. Average treatment time was 2 minutes 6 seconds. All patients reported a reduction in their menstrual loss and 87.5% were satisfied with their treatment after 1 year follow-up. One patient required overnight admission for analgesia while 15 patients were treated on a day case basis using light general anaesthesia. Sixty-seven per cent of patients reported a reduction in dysmenorrhoea scores at 1 year, two patients reported no change in symptoms and one patient reported a modest increase. One patient had a hysterectomy 10 months after treatment despite being amenorrhoeic. The indication for hysterectomy was pelvic pain (which was present before endometrial ablation). There were few minor complications but no uterine perforation or emergency hysterectomies.
