探讨高频超声结合彩色多普勒超声在腹股沟斜疝和股疝中的应用及临床价值。

选取2018年1月至2021年4月在宁国市人民医院接受术前高频超声和彩色多普勒超声检查的患者103例作为研究对象。统计受试者手术检查结果、高频超声、彩色多普勒超声以及两者联合检查结果，对影像学表现及诊断效能进行比较。

经手术探查，103例受试者中，腹股沟斜疝85例、股疝18例；单独检测时，高频超声对斜疝和股疝的准确度均高于彩色多普勒超声，联合检测准确度高于单独检测；在单独检测时，高频超声检测灵敏度、特异度、阳性预测率及阴性预测率最高。联合检测时灵敏度、特异度、阳性预测率及阴性预测率均高于单独检测。

高频超声成像在区分股疝和腹股沟疝方面具有良好准确度，彩色多普勒超声可以通过显示血流信号等优势为手术方案提供选择依据，两者联合可提供更直观准确的术前诊断依据。

To investigate the application and clinical value of high frequency ultrasound combined with color Doppler ultrasound in indirect inguinal hernia and femoral hernia.

A total of 103 patients who received high-frequency ultrasound and color Doppler ultrasound before operation in our hospital from January 2018 to April 2021 were selected as the study subjects. All subjects received high-frequency ultrasound and color Doppler ultrasound. The results of surgical examination, high-frequency ultrasound, color Doppler ultrasound and their combined results, as well as imaging manifestations, diagnostic efficacy of single detection and combined detection were compared.

After surgical exploration, 85 cases of oblique inguinal hernia and 18 cases of femoral hernia were found in 103 subjects by surgical exploration. The accuracy of high-frequency ultrasound for oblique hernia and femoral hernia was higher than that of color Doppler ultrasound alone, and the accuracy of combined detection was higher than that of single detection. When tested alone, the sensitivity, specificity, positive prediction rate and negative prediction rate of high frequency ultrasound were the highest. The sensitivity, specificity, positive prediction rate and negative prediction rate of combined detection were higher than those of single detection.

When the preoperative examination is carried out by experienced physicians, high-frequency ultrasound imaging has good accuracy in distinguishing femoral hernia from inguinal hernia, and color Doppler ultrasound can provide a basis for the selection of surgical plan by displaying blood flow signals and other advantages. The combination of the two methods can provide a more intuitive and accurate basis for preoperative diagnosis.
