探讨高频超声在腹股沟斜疝临床诊断中应用的准确性。

选取2017年1月至2020年1月芜湖市第五人民医院接收的80例疑似腹股沟斜疝患者为研究对象。纳入患者均接受传统外科检查及高频超声检测，比较并分析两种检查的阳性率、误诊及漏诊率、准确性、敏感性及特异性情况。

与外科检查比较，高频超声诊断的阳性率相对较高，差异有统计学意义（P<0.05）；与外科检查比较，高频超声检查的漏诊率较低、准确性较高，差异有统计学意义（P<0.05）；与外科检查比较，高频超声检查的敏感性、特异性均较高，差异有统计学意义（P<0.05）。

对腹股沟斜疝患者采用高频超声诊断，其诊断的准确性及敏感性均相对较高，且该项检测操作简单、快捷及显像清晰，可重复操作性强，老人及儿童均可耐受，有助于对腹股沟斜疝患者进行术前鉴别与诊断，具有较高的临床应用价值。

To investigate the application and accuracy of high frequency ultrasound in the clinical diagnosis of indirect inguinal hernia.

From January 2017 to January 2020, 80 patients with suspected inguinal hernia admitted to the Fifth People's Hospital of Wuhu City were selected as the research objects. The selected persons all received traditional surgical examinations and high-frequency ultrasound tests. The positive rate, misdiagnosis and missed diagnosis rates, accuracy, sensitivity and specificity of the two tests were compared and analyzed.

Compared with surgical examination, the positive rate of high-frequency ultrasound diagnosis was relatively high (P<0.05); compared with surgical examination, the missed diagnosis rate of high-frequency ultrasound examination was lower and the accuracy was higher (P<0.05); compared with surgical examination, the sensitivity and specificity of high-frequency ultrasonography were high (P<0.05).

When high-frequency ultrasound is used to diagnose patients with indirect inguinal hernia, the accuracy and sensitivity of the diagnosis are relatively high, and the test has the characteristics of simple, fast and clear imaging, and has strong repeatability. It can be tolerated by the elderly and children. It is helpful for preoperative identification and diagnosis of patients with indirect inguinal hernia. And it has high clinical application value.
