Menorrhagia is a common gynaecological complaint, with significant burden to both its sufferers and health service providers. The first line of treatment is usually medical/pharmaceutical although in some cases surgery is required. There are now a number of minimally invasive surgical techniques available that ablate the uterine lining and prevent the need for the removal of the uterus. Microwave endometrial ablation (MEA) is one of these techniques, and this paper investigates the effect of the working temperature on outcome.
A retrospective case note review of women who underwent MEA between June 2000 and August 2004. All women had a hysteroscopy followed by MEA. The duration of the procedure and mean working temperature of the MEA treatment was calculated. Women were followed up 6-8 months after surgery.
Two hundred and eleven women underwent the procedure, with an average duration of menorrhagia of 30 months prior to the procedure. Eighty-nine percent attended follow-up, 80 % were satisfied with the procedure and 40 % were amenorrhoeic. When the procedure was performed at higher working temperature within the manufacturers guidelines women were more likely to be amenorrhoeic (78.4 vs. 77.1 °C, p = 0.014).
MEA is more effective in treating menorrhagia when used at a higher operating temperature.
月经过多是一种常见的妇科病症，给患者和医疗服务提供者都带来了沉重负担。一线治疗通常是药物治疗，不过在某些情况下需要进行手术。现在有多种微创外科技术可用于消融子宫内膜，从而避免子宫切除。微波子宫内膜消融术（MEA）就是其中一种技术，本文研究了工作温度对治疗结果的影响。
对2000年6月至2004年8月期间接受MEA治疗的女性进行回顾性病例记录审查。所有女性均先接受宫腔镜检查，然后进行MEA。计算手术时长和MEA治疗的平均工作温度。术后对女性进行6 - 8个月的随访。
211名女性接受了该手术，术前平均月经过多持续时间为30个月。89%的患者接受了随访，80%对手术满意，40%出现闭经。当在制造商指南规定的较高工作温度下进行手术时，女性更有可能出现闭经（78.4对77.1°C，p = 0.014）。
MEA在较高工作温度下用于治疗月经过多时效果更佳。
