探究彩色多普勒血流显像及高频超声在腹股沟斜疝、直疝及股疝鉴别诊断中的应用价值。

回顾性分析2019年1月至2021年12月，合肥市第三人民医院超声科接诊的62例拟诊断为腹股沟疝或股疝患者的资料。总结彩色多普勒血流显像及高频超声检查的影像表现以及内容物检出结果，分析其在腹股沟疝、股疝鉴别诊断中的价值。

高频超声与多普勒超声单一检测的漏诊率和误诊率均高于两者联合检测结果，两者联合检测的诊断准确率高于高频超声或多普勒超声单项检测；腹股沟斜疝、直疝及股疝的疝内容物以肠管占比最高，分别为37.50%、35.29%、40.00%，其次为网膜，分别为25.00%、23.53%、20.00%；多普勒血流显像能够明确腹股沟直疝患者疝内容物有少量的血流信号，而腹沟斜疝患者中绞窄性疝和难复性疝内容物未见明显的血流信号，易复性疝可见星点状及短线状血流信号，嵌顿性疝中可见少许散在的点状血流信号。

多普勒血流显像及高频超声可清楚的显示腹股沟斜疝、直疝及股疝的解剖结构，疝内容物情况、病变位置及其血流情况，在腹股沟斜疝、直疝及股疝的鉴别诊断中具有较高的临床应用价值。

To explore the application value of color Doppler flow imaging and high-frequency ultrasound in the differential diagnosis of indirect, direct inguinal hernia and femoral hernia.

The data of 62 patients with inguinal hernia or femoral hernia who came to the Ultrasound Department of Third People's Hospital of Hefei from January 2019 to December 2021 were retrospectively analyzed. To summarize the imaging manifestations and contents detection results of color Doppler flow imaging and high-frequency ultrasonography, and analyze their differential diagnostic value in groin hernia.

The missed diagnosis rate and misdiagnosis rate of single detection of high-frequency ultrasound or Doppler ultrasound were higher than those of combined detection, and the accurate diagnosis rate of combined detection was higher than that of single detection of high-frequency ultrasound or Doppler ultrasound. In the distribution of hernia contents in groin hernia, the intestinal canal has the highest proportion, accounting for 37.50%, 35.29%, and 40.00%, respectively, followed by the omentum, accounting for 25.00%, 23.53%, and 20.00%, respectively; Doppler flow imaging can confirm that there is a small amount of blood flow signal in the hernia contents in patients with direct inguinal hernia; while in indirect hernia, there is no obvious blood flow in the contents of strangulated hernia and refractory hernia in patients; stellate and short-line blood flow signals can be seen in reducible hernias; a few scattered punctate blood flow signals can be seen in incarcerated hernias.

Doppler flow imaging and high-frequency ultrasound can clearly display the anatomical structure,, hernia content, lesion location, and blood flow of indirect, direct inguinal hernia and femoral hernia, which has high clinical value in differential diagnosis of indirect, direct inguinal hernia and femoral hernia.
