摘　　要：目的:观察超声对子宫内膜癌(endometrial carcinoma,EC)及子宫内膜增生症(endometrial hyperplasia,EH)的鉴别诊断效能,分析其影像学特征。方法:回顾性分析2020年10月—2022年10月金乡县人民医院收治的60例子宫内膜病变患者,据手术病理结果将30例EC患者列为EC组,将30例EH患者列为EH组,统计超声对不同子宫内膜病变类型患者的诊断准确率、灵敏度、特异度,分析并对比两组患者的超声影像学特征。结果:以病理结果为金标准,经阴道超声对EC和EH的诊断准确率为81.67%(49/60),灵敏度为83.33%(25/30),特异度为80.00%;EC组的子宫内膜增厚、内膜增厚不均匀、边缘模糊、宫腔体积明显增大、宫腔内回声分布不均匀,经彩色多普勒超声检查后,EC组的子宫内可见丰富血流信号,血流显示率更高,血流阻力指数更低,搏动指数更高,与EH组存在显著差异(P<0.05)。结论:经阴道超声对子宫内膜癌具有较高诊断效能,实施常规检查可有效观察患者的子宫内膜厚度、子宫形态及大小、内部回声分布,实施多普勒血流信号检查可有效明确患者的子宫内部血流信号及血流阻力指数,进而实现对EC、EH的有效鉴别。Objective To observe the differential diagnostic efficacy of ultrasound in endometrial carcinoma(EC)and endometrial hyperplasia(EH),and analyze its imaging characteristics.Methods Retrospective analysis was performed on 60 patients with endometrial lesions admitted to Jinxiang County People's Hospital from October 2020 to October 2022.According to the pathological results of surgery,30 EC patients were classified as EC group and 30 EH patients as EH group.The diagnostic accuracy,sensitivity and specificity of ultrasound for patients with different types of endometrial lesions were analyzed.The ultrasound imaging features of the two groups were analyzed and compared.Results With pathological results as the gold standard,The accuracy,sensitivity and specificity of transvaginal ultrasound for endometrial cancer were 81.67%(49/60),83.33%(25/30)and 80.00%respectively.In the EC group,endometrial thickening,endometrial thickening unevenly,blurred edges,uterine volume significantly increased,and intrauterine echo distribution was uneven.After color Doppler ultrasound examination,abundant blood flow signals were visible in the EC group,with higher blood flow display rate,lower blood flow resistance index,and higher pulse index,which were significantly different from those in the EH group(P<0.05).Conclusion Transvaginal ultrasound has a high diagnostic efficiency for endometrial carcinoma.Routine examination can effectively observe the endometrial thickness,shape and size of the uterus,and internal echo distribution of patients.Doppler blood flow signal examination can effectively determine the internal blood flow signal and blood flow resistance index of patients,so as to achieve effective differentiation between EC and EH.
