探讨高频超声对腹股沟疝患者超声学特征及鉴别诊断价值。

选择2018年1月至2021年6月于解放军海军安庆医院手术结果证实为腹股沟疝的患者158例为研究对象，患者均接受高频超声检查，观察其影像学特点，并与术中结果进行比较，对比超声诊断效果。

经手术结果证实，158例患者中共计183侧，其中斜疝90侧，直疝86侧，股疝7侧。高频超声诊断时腹股沟疝178侧，其中斜疝89侧，直疝86侧，斜疝合并直疝14侧，股疝3例；另超声诊断脂肪瘤1例，鞘膜积液2例，股疝误诊为囊肿2例。高频超声对腹股沟疝鉴别效果准确度96.50%，阳性预测值为0.975。

高频超声在腹股沟疝诊断中有较高应用价值，可用于诊断鉴别腹股沟疝。

To investigate the value of high frequency ultrasound in the ultrasonic characteristics and differential diagnosis of inguinal hernia.

A total of 158 patients admitted from January 2018 to June 2021 with inguinal hernia confirmed by surgical results were selected as the study subjects. A high-frequency ultrasound examination was performed on all patients to observe their imaging characteristics and compare them with the intraoperative results to determine the diagnostic effects of ultrasound.

183 of 158 patients were confirmed by operation, including 90 oblique hernias, 86 direct hernias, and 7 femoral hernias. There were 178 cases of inguinal hernia diagnosed by high-frequency ultrasound, including 89 cases of oblique hernia, 86 cases of direct hernia, 14 cases of indirect hernia combined with direct hernia, and 3 cases of femoral hernia. In addition, ultrasonography diagnosed 1 case of lipoma, 2 cases of hydrocele, and 2 cases of femoral hernia misdiagnosed as cysts. The accuracy of high-frequency ultrasound in inguinal hernia identification was 96.50%, and the positive predictive value was 0.975.

High-frequency ultrasound has high application value in the diagnosis of inguinal hernia, which can be used for diagnosis and differentiation of inguinal hernia, and can be popularized in clinical application.
