探讨高频超声和多普勒超声在腹外疝诊断中的应用价值。

选取2018年9月至2019年9月琼海市人民医院超声科收治疑似腹外疝患者144例。根据患者使用的超声检查设备不同，将患者分为高频超声和多普勒超声组。以手术病理诊断为金标准，与超声诊断结果进行对比，评估高频超声与多普勒超声单项检测与联合检测的阳性检出率、准确率、灵敏度及特异度。

高频超声与多普勒超声联合检测的漏诊率低于高频超声与多普勒超声单项检测，高频超声与多普勒超声联合检测的误诊率低于高频超声与多普勒超声单项检测，高频超声与多普勒超声联合检测的准确诊断率为高于高频超声与多普勒超声单项检测，差异均有统计学意义（P<0.05）。高频超声与多普勒超声联合检测的灵敏度与特异度分别为98.92%、98.04%，高频超声与多普勒超声单项检测的灵敏度与特异度分别为87.10%、90.20%与82.80%、84.31%，高频超声与多普勒超声联合检测的漏诊率与误诊率均为0.01%。

高频超声与多普勒超声对腹外疝有较高的诊断率，两者联合诊断的诊断率、灵敏度与特异度显著高于单项诊断，对腹外疝分类提高准确诊断信息，可为腹外疝临床方案制定及干预治疗提供依据。

To investigate the application value of high-frequency ultrasound and Doppler ultrasound in the diagnosis of abdominal external hernia.

144 patients with suspicion of abdominal external hernia who were admitted to the hospital between September 2018 and September 2019 were selected as the subjects. They were examined by high-frequency ultrasound and Doppler ultrasound, respectively. With pathological diagnosis as the golden standard, the positive detection rates, accuracy rates, sensitivities and specificities of single detection and combined detection of high-frequency ultrasound and Doppler ultrasound were evaluated.

The sensitivity and specificity of the combined detection of high-frequency ultrasound and Doppler ultrasound (98.92% and 98.04%) were higher than those of high-frequency ultrasound (87.10% and 90.20%) and Doppler ultrasound (82.80% and 84.31%). The missed diagnosis rate and misdiagnosis rate of high-frequency ultrasound combined with Doppler ultrasound (0.01% and 0.01%) were lower than those of high-frequency ultrasound (0.08% and 0.11%) and Doppler ultrasound (0.04% and 0.06%). The accuracy of high-frequency ultrasound combined with Doppler ultrasound (98.61%) was higher than that of high-frequency ultrasound (88.19%) or Doppler ultrasound (83.33%).

The diagnosis rates of both high-frequency ultrasound and Doppler ultrasound are high for abdominal external hernia. The combined diagnosis rate, sensitivity and specificity of the two are significantly higher than single diagnosis. The accurate diagnosis of the type of abdominal external hernia can provide a basis for the development of clinical plan and interventional treatment of abdominal external hernia.
