探讨高频超声联合多普勒超声用于腹外疝诊断临床价值。

选取2019年8月至2020年8月联勤保障部队第九一〇医院普外科收治的疑似腹外疝患者，均采用高频超声和多普勒超声进行检查，记录高频超声和多普勒超声探查腹外疝的超声图像表现，以手术结果确诊；分别计算和比较高频超声、多普勒超声以及两者联合检查的诊断准确率、误诊率、漏诊率、灵敏度、特异度以及阳性检出率。

（1）高频超声联合多普勒超声诊断腹外疝的漏诊率（1.40%）、误诊率（1.98%）低于高频超声（12.59%、9.90%）、多普勒超声（17.48%、15.84%）单独检测，而联合检测的诊断准确率（98.36%）明显高于高频超声（88.52%）、多普勒超声（83.20%）单独检测（P<0.05）；（2）高频超声联合多普勒超声诊断腹外疝的阳性检测率（98.60%）、灵敏度（98.60%）、特异度（98.02%）均高于高频超声（92.59%、87.41%、90.10%）、多普勒超声（88.06%、82.52%、84.16%）单独检测（P<0.05）。

高频超声和多普勒超声均有较高的腹外疝诊断准确率，但是两者联合检测的诊断准确率、阳性检测率、灵敏度、特异度更高，漏诊率、误诊率更低，可为临床诊断及治疗腹外疝提供参考。

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

The suspected patients with external abdominal hernia who were admitted to the Department of General Surgery in our hospital from August 2019 to August 2020 were examined by high frequency ultrasound and Doppler ultrasound, and the ultrasonic images of high frequency ultrasound and Doppler ultrasound were recorded in detail. The diagnosis was confirmed by surgery. The accuracy, misdiagnosis rate, missed diagnosis rate, sensitivity, specificity and positive detection rate of high frequency ultrasound, Doppler ultrasound and the combined examination were calculated and compared.

(1) The missed diagnosis rate and misdiagnosis rate of high frequency ultrasound combined with Doppler ultrasound in the diagnosis of external abdominal hernia were lower than those of high frequency ultrasound alone and Doppler ultrasound detection alone [1.40% vs 12.59%, 17.48%; 1.98% vs 9.90%, 15.84%] (P<0.05), and the diagnostic accuracy of combined detection was significantly higher than that of single detection (98.36% vs 88.52%, 83.20%) (P<0.05); (2) The positive detection rate (98.60%), sensitivity (98.60%) and specificity (98.02%) of high frequency ultrasound combined with Doppler ultrasound in the diagnosis of external abdominal hernia were higher than those of high frequency ultrasound alone (92.59%, 87.41%, 90.10%) and Doppler ultrasound detection alone (88.06%, 82.52%, 84.16%) (P<0.05).

High frequency ultrasound and Doppler ultrasound have high accuracy in diagnosis of external abdominal hernia, but the diagnostic accuracy, positive detection rate, sensitivity and specificity of the combined detection are higher, the missed diagnosis rate and misdiagnosis rate are lower, which provides reference for clinical diagnosis and treatment of externalabdominal hernia.
