RESUMEN
Objective To compare the efficacy between microwave endometrial ablation(MEA) and abdominal hysterectomy(AH) in the treatment of abnormal uterine bleeding(AUB).Methods A total of 80 patients with AUB was divided into two groups,either receiving MEA(40 patients) or receiving AH(40 patients).The clinical efficacy,operation time,intraoperative blood loss,white blood cell(WBC) count,and neutrophil granulocyte rate(NGR) before and after operation were compared.Results The effective rate for abnormal uterine bleeding was not significantly different between MEA(97.5%,39/40) and AH(100%,40/40)(?2=0.000,P=1.000).As compared with AH,MEA was characterized by a shorter operation time(4.8?1.2 min vs 102.5?34.6 min;t=17.848,P=0.000) and less intraoperative blood loss(0 ml vs 138.3?40.6 ml;t=21.544,P=0.000).Conclusions Microwave endometrial ablation is a novel and efficient minimally invasive method for abnormal uterine bleeding.
