目的分析经阴道三维超声(3D-TVS)在妇科疾病诊断中的应用价值。方法选取医院收治的38例妇产科门诊或住院患者,经手术或宫腔镜检查确诊为盆腔包块12例、内膜息肉9例、先天性子宫畸形7例、子宫黏膜下肌瘤5例、子宫内膜增厚5例,全部患者均接受经阴道三维超声(3D-TVS)、经阴道二维超声(2D-TVS)检查,将检查结果与宫腔镜、手术检查结果比较。结果以手术或宫腔镜检查结果为标准,3D-TVS检出盆腔包块11例、内膜息肉9例、先天性子宫畸形7例、子宫黏膜下肌瘤5例、子宫内膜增厚5例,3D-TVS对妇科疾病检出率为97.37%;2D-TVS检出盆腔包块11例、内膜息肉7例、先天性子宫畸形5例、子宫黏膜下肌瘤5例、子宫内膜增厚4例,2D-TVS为检查准确率为84.21%,2种检查方法结果比较差异有统计学意义(P<0.05)。结论与2D-TVS比较,3D-TVS更能准确、直观地显示病变情况,提高诊断准确性,为临床疾病诊断、治疗、预后提供参考依据,具有较高的临床应用价值。 Objective To analyze the value of transvaginal three-dimensional ultrasound (3D-TVS) in the diagnosis of gynecological diseases. Methods 38 cases of obstetrics and gynecology outpatients or inpatients admitted to the hospital were selected, and 12 cases of pelvic masses, 9 cases of endometrial polyps, 7 cases of congenital uterine malformation, 5 cases of uterine submucosal fibroids were diagnosed by operation or hysteroscopy. , 5 cases of endometrial thickening, all patients received transvaginal three-dimensional ultrasound (3D-TVS), transvaginal two-dimensional ultrasound (2D-TVS) examination, the test results and hysteroscopy, surgical examination results were compared. Results According to the results of surgery or hysteroscopy, 3D-TVS detected 11 cases of pelvic mass, 9 cases of endometrial polyps, 7 cases of congenital uterine malformation, 5 cases of uterine submucous myoma, 5 cases of endometrial thickening For example, the detection rate of gynecological diseases by 3D-TVS was 97.37%; 11 cases of pelvic masses by 2D-TVS, 7 cases of endometrial polyps, 5 cases of congenital uterine malformation, 5 cases of uterine submucous myoma, In 4 cases, the accuracy of 2D-TVS was 84.21%. There was significant difference between the two methods (P <0.05). Conclusion Compared with 2D-TVS, 3D-TVS can display the pathological changes more accurately and accurately and improve the accuracy of diagnosis. It provides a reference for the diagnosis, treatment and prognosis of clinical diseases, and has a high clinical value.
