探讨彩色多普勒血流显像在单纯性腹股沟疝诊断中的应用效果及声像图特征。

回顾性分析2018年1月至2020年5月安徽省合肥市庐江县人民医院超声科接诊的57例拟诊断为单纯性腹股沟疝患者的资料。全部患者均接受彩色多普勒超声检查。描述手术探查结果、彩色多普勒超声探查结果分析彩色多普勒超声对单纯性腹股沟疝的诊断效能。

57例患者中男性52例，女性5例，平均（59.27±13.56）岁，平均病程（4.51±1.48）个月。经过手术诊断，57例确诊为单纯性腹股沟疝，直疝9例，斜疝47例，股疝1例。利用彩色多普勒共诊断出单纯性腹股沟疝病灶55例，分别有1例斜疝和1例直疝出现误诊，未出现漏诊。彩色多普勒超声对单纯性腹股沟疝的诊断灵敏度为96.49%（55/57），诊断特异度为100.00%（7/7），诊断准确度为96.88%（62/64），阳性预测值为100.00%（57/57），阴性预测值为77.78%（7/9），彩色多普勒超声与手术两种诊断方法的Kappa值为0.838。彩色多普勒对单纯性腹股沟疝的诊断ROC曲线下面积为0.809。

彩色多普勒超声在单纯性腹股沟疝的诊断中，具有良好的准确性和使用价值，但实际工作中需要结合影像学结果、临床表现、化验指标等多种因素进行综合考虑，为患者的术前诊断提供良好的参考依据。

To explore the application effect and sonographic characteristics of color Doppler blood flow imaging in the diagnosis of simple inguinal hernia.

A retrospective analysis were conducted on 57 patients who were diagnosed with simple inguinal hernia admitted to Lujiang County People's Hospital from January 2018 to May 2020. All patients underwent color Doppler ultrasound examination. Describe the results of surgical exploration and color Doppler ultrasound detection and analyze the diagnostic efficacy of color Doppler ultrasound for simple inguinal hernia.

There were 52 males and 5 females, with an average age of (59.27±13.56) years and an average disease duration of (4.51±1.48) months. After surgical diagnosis, 57 cases were diagnosed as simple inguinal hernia, with 9 cases of direct hernia, 47 cases of indirect hernia and 1 cases of femoral hernia. A total of 55 cases of inguinal hernia were diagnosed by color Doppler. One indirect hernia and one direct hernia were misdiagnosed without any missed diagnosis. The diagnostic sensitivity of color Doppler ultrasound for inguinal hernia was 96.49% (55/57), the diagnostic specificity was 100.00% (7/7), the diagnostic accuracy was 96.88% (62/64), the positive predictive value was 100.00% (57/57), the negative predictive value was 77.78% (7/9), and the Kappa value of the two diagnostic methods of color Doppler ultrasound and surgery was 0.838. The area under the ROC curve for the diagnosis of simple inguinal hernia by color Doppler was 0.809.

Color Doppler ultrasound has good accuracy and useful value in the diagnosis of simple inguinal hernia, but in actual work, it needs to be combined with imaging results, clinical manifestations, laboratory indicators and other factors to comprehensively consider for providing good preoperative diagnosis.
