两种超声检查对子宫内膜病变诊断价值的比较

Comparison of the clinical value of two kinds of ultrasound in the diagnosis of endometrial lesions

目的 探讨经阴道超声检查诊断子宫内膜病变的临床价值.方法 回顾性分析120例病理诊断确诊为子宫内膜病变患者的临床资料,其中子宫内膜增生58例,子宫内膜息肉29例,子宫黏膜下肌瘤25例和子宫内膜癌8例;将术前腹部超声和阴道超声诊断结果分别与病理诊断结果进行对照,计算两种超声检查诊断准确率,并进行比较.结果 子宫内膜增生、子宫内膜息肉、子宫黏膜下肌瘤和子宫内膜癌经阴道超声检查的诊断准确率分别为96.6％、100.0％、80.0％、75.0％,总准确率为92.5％;经腹部超声检查分别为82.8％、82.8％、60.0％、25.0％,总准确率为74.2％;经阴道超声检查的总诊断准确率明显高于经腹部超声检查（χ2=3.920,P＜0.05）.结论 经阴道超声检查对子宫内膜病变具有较高的诊断价值.

Objective To study the clinical value of transvaginal ultrasonography in the diagnosis of endometrial lesions.Methods The clinical data of 120 patients with endometrial lesions diagnosed by pathology,including endometrial hyperplasia 58 cases,endometrial polyps 29 cases,submucosal myoma of uterus 25 cases and endometrial carcinoma 8 cases were retrospectively analyzed.The results of preoperative abdominal ultrasonography and transvaginal ultrasonography were compared with the pathological results respectively,the diagnostic accuracy was calculated and compared.Results The diagnostic accuracy of endometrial hyperplasia,endometrial polyps,submucosal myoma of uterus and endometrial carcinoma examined by transvaginal ultrasonography were 96.6%,100.0%,80.0%,75.0% respectively,the total accuracy rate was 92.5% ;Those of abdominal ultrasonography examination were 92.5%,82.8%,60.0%,25.0% respectively,the total accuracy rate was 74.2% ;The total diagnostic accuracy of transvaginal ultrasonography was obviously higher than that of abdominal ultrasonography,the difference was statistically significant（χ2 =3.920,P 〈 0.05）.Conclusion Transvaginal ultrasonography has high value in the diagnosis of endometrial lesions.
