经阴道彩色多普勒超声诊断宫颈癌的临床观察

Clinical Observation of Transvaginal Color Doppler Ultrasound in the Diagnosis of Cervical Cancer

目的:研究经阴道彩色多普勒超声诊断宫颈癌的临床应用效果。方法:回顾分析某院2017年1月~2019年4月收治的宫颈癌患者55例作为观察组,另择取同期健康体检者宫颈群体55例作为对照组,研究对象均采用经阴道彩色多普勒超声诊断,比较两组宫颈大小、血流参数、诊断结果与血流信号分布。结果:观察组宫颈可探及低至中等回声包块直径2.5cm,宫颈图像表示边缘不规整且不清晰,内部回声不均匀;观察组宫颈内存在大量血管网,对照组宫颈内部呈点状或者短线状血流信号,观察组宫颈前后径与左右径较对照组高,收缩期峰值血流速度较对照组高,阻力指数较对照组低(P<0.05),具有统计学差异;将病理检查结果作为诊断的金标准,宫颈癌患者确诊确诊53例占96.36%,误诊1例占1.81%,漏诊1例占1.81%。结论:对宫颈癌患者采用经阴道彩超多普勒超声诊断能早期确诊疾病,具有较高的检查分辨率,明确诊断疾病效果,为后续治疗提供参考依据,值得推荐。

Objective:To study the clinical effect of transvaginal color Doppler ultrasound in the diagnosis of cervical cancer.Methods:55 cases of patients with cervical cancer treated in a hospital from January 2017 to April 2019 were retrospectively analyzed and divided into the observation group,and another 55 healthy people in the same period were selected as control group.All the subjects were diagnosed by transvaginal color Doppler ultrasound.The size of cervix,blood flow parameters,diagnosis results and blood flow signal distribution were compared between the two groups.Results:In the observation group,the diameter of the hypo-to-moderate echo mass was 2.5 cm,the image of cervix showed that the edge was irregular and unclear,and the internal echo was not uniform.There was a large number of vascular network in the cervix of the observation group,and the internal cervix of the control group showed punctate or short-term blood flow signals.The anterior and posterior cervical diameters and left and right diameters of the observation group were higher than those of the control group.The peak systolic blood flow velocity was higher and the resistance index was lower than those of the control group,with statistical significance(P<0.05).The results of pathological examination were taken as the gold standard for diagnosis,53 cases of cervical cancer were diagnosed,accounting for 96.36%;1 case was misdiagnosed,accounting for 1.81%;1 case was missed,accounting for 1.81%.Conclusion:Transvaginal color Doppler ultrasound can diagnose cervical cancer in early stage,with high detection resolution and definite diagnostic effect,which can provide reference for follow-up treatment and is worthy of recommending.
