探究腹股沟斜疝临床诊断中高频彩超多普勒超声的应用及对超声诊断符合率、疝内容物判断符合率的影响。

选取2015年12月至2020年4月于合肥市第三人民医院行腹股沟疝探查术，术前已行高频彩超和彩色多普勒超声成像（CDFI）的60例患者纳入本研究，并对其高频超声及多普勒图像特征进行总结，同时与手术结果进行对比。

手术结果证实60例患者均为腹股沟斜疝，高频超声可清晰显示腹股沟疝疝块的位置及与周围组织的位置关系，多数疝内容物整体呈椭圆形或长条形，边界清晰、光滑，活动度可，边缘可见纤细暗带通向腹腔，内部回声多为液性或实性混合回声，且不同类型斜疝的血流信号、血液流速曲线不同；以手术结果作为金标准，高频超声的诊断灵敏度和诊断符合率均明显优于彩色多普勒（94.55%比81.82%，P<0.05；80.00%比93.33%，P<0.05），总体而言高频超声和彩色多普勒诊断腹股沟斜疝的诊断效能均较良好，AUC面积分别为0.863和0.816，诊断一致率也较理想。

高频超声与CDFI图像的侧重点和表现不同，在诊断腹股沟斜疝方面高频超声结果与手术结果符合率较高，与CDFI相比在灵敏度及疝内容物判断符合率方面更具优势，而CDFI在鉴别疝块血流信号以及斜疝的具体类型上更具重要参考价值，临床上应依据患者临床症状及体格检查可灵活选用两种超声方式。

To explore the application of high frequency color Doppler ultrasound in the clinical diagnosis of indirect inguinal hernia and its influence on the coincidence rate of ultrasound diagnosis and hernia content judgment.

60 patients who underwent inguinal hernia exploration and high-frequency color Doppler flow imaging (CDFI) before operation in the Third People's Hospital of Hefei from December 2015 to April 2020 were included in this study. The characteristics of high-frequency ultrasound and Doppler image were summarized and compared with the results of operation.

60 cases of indirect inguinal hernia were confirmed by surgical results. High frequency ultrasound could clearly show the location of inguinal hernia mass and its relationship with surrounding tissues. Most of the hernia contents were oval or strip, with clear and smooth boundary and good mobility. The thin dark band leading to the abdominal cavity could be seen at the edge. The internal echo was mostly liquid or solid mixed echo, and the blood flow signals of different types of indirect hernia were found variable. With the results of operation as the gold standard, the diagnostic sensitivity and coincidence rate of HFUS were significantly better than those of CDFI (94.55% vs 81.82%, P<0.05). In general, the diagnostic efficiency of high frequency ultrasound and color Doppler ultrasound in the diagnosis of indirect inguinal hernia was good, AUC area was 0.863 and 0.816, respectively.

High frequency ultrasound and CDFI image focus and performance are different. In the diagnosis of indirect inguinal hernia, the high-frequency ultrasound results and surgical results consistent rate is higher. Compared with CDFI, coincidence rateof high frequency ultrasoundin sensitivity and hernia content judgment are better, and CDFI has more important reference value in the identification of hernia mass blood flow signal and the specific types of indirect hernia. Clinically, thetwo kinds of ultrasonic methods should be selected flexibly, according to the clinical symptoms and physical examinationof patients.
