探讨彩色多普勒超声（简称彩超）检查中联合高低频探头、双体位扫查对腹股沟疝诊断准确性的影响。

回顾性分析2018年2月至2020年2月，三亚市人民医院240例疑似腹股沟疝患者的临床资料。所有患者术前均行彩超检查，先实施低频探头、卧位扫查（A组），再实施高低频探头、双体位扫查（B组）。分析两种方法检查结果及对腹股沟疝诊断效能。

A组腹股沟疝检出阳性率为68.33%，低于B组的80.00%，差异有统计学意义（P<0.05）；金标准：临床手术证实。B组对腹股沟疝诊断灵敏度、特异度、准确度、阳性预测值、阴性预测值分别为97.92%、91.67%、96.67%、97.92%、91.67%，高于A组的76.04%、62.50%、73.33%、89.02%、39.47%；B组对直疝、斜疝诊断符合率分别为98.36%、97.14%，高于A组的85.25%、60.00%，差异有统计学意义（P<0.05）。

腹股沟疝术前彩超检查中应用高低频探头联合双体位扫查可提升诊断准确性。

To investigate the effect of color Doppler ultrasound combined with high and low frequency probe and bipartite scanning on the diagnostic accuracy of inguinal hernia.

Clinical data of 240 patients with suspected inguinal hernia in Sanya people's hospital from February 2018 to February 2020 were analyzed retrospectively. All patients underwent color Doppler ultrasonography preoperatively. First, low-frequency probe and lying position scanning were performed (group A), and then high and low frequency probe with bipartite position scanning were performed (group B). The results of the two methods and their diagnostic efficacy for inguinal hernia were analyzed.

The positive rate of inguinal hernia in group A was 68.33%, which was lower than 80.00% in group B (P<0.05); Gold standard: confirmed by clinical operation. The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value of inguinal hernia in group B were 97.92%, 91.67%, 96.67%, 97.92% and 91.67%, respectively, which were higher than 76.04%, 62.50%, 73.33%, 89.02% and 39.47% in group A; The diagnostic coincidence rates of direct hernia and indirect hernia in group B were 98.36% and 97.14%. respectively, which were higher than 85.25% and 60.00% in group A (P<0.05).

Application of high and low frequency probe combined with bipartite scan in preoperative color Doppler ultrasonography of inguinal hernia can improve the diagnostic accuracy.
