微波子宫内膜消除术与全子宫切除术的比较

A comparison between microwave endometrial ablation and total hysterectomy

目的 比较微波子宫内膜消除术 (MEA)与经腹全子宫切除术治疗月经过多的疗效。 方法 将 6 0例月经过多的患者分为MEA组与全子宫切除组各 30例 ,比较两组对治疗月径过多的疗效、手术的出血量、手术时间、能否保留子宫及术后恢复时间。 结果 MEA组与全子宫切除组治疗月经过多的有效率分别为 96 % (2 9 30 )和 10 0 % (30 30 ) ,χ2 =0 ,P =1 0。但两组手术时间分别为 (4 0± 1 1)min和 (6 8 3± 1 9)min ,t=- 16 0 4 2 ,P =0 0 0 ;平均术中出血分别为 0ml和 5 0ml。 结论 微波子宫内膜消除术是治疗月经过多的一种新的微创手术 ,其疗效与全子宫切除术相近 ,从保留子宫、术后恢复等方面MEA明显优于全子宫切除术。

Objective To compare the curative effects between microwave endometrial ablation (MEA) and total hysterectomy for the treatment of menorrhagia. Methods Sixty patients with menorrhagia were divided into 2 groups with 30 patients in each group, either to MEA or to total hysterectomy (control group). The intraoperative blood loss, operating time, sparing or unsparing of uterus, and length of recovery of the 2 groups were compared. Results The effective rates for menorrhagia, operating time, and mean blood loss of MEA group and control group was 96% (29/30) and 100% (30/30) (χ2=0,P=1.0), (4.0±1.1) min and (68.3±1.9) min (t=-160.42, P=0.00), 0 ml and 50 ml, respectively. Conclusions MEA is a novel minimally invasive method for menorrhagia, and its curative effects are similar to that of total hysterectomy. When considered in terms of sparing of uterus and postoperative recovery, MEA is obviously superior to total hysterectomy.
