分析彩色多普勒超声（以下简称彩超）结合血清C反应蛋白（CRP）在腹股沟嵌顿疝中诊断的临床意义。

选择2017年3月至2020年3月于阜阳市第五人民医院收治的60例腹股沟疝患者作为研究对象，每组患者30例。对照组为门诊收治的择期腹股沟疝患者，采用彩超结合CRP诊断；观察组为急诊收治的腹股沟嵌顿疝患者，采用彩超结合CRP诊断。分析2组患者的诊断效能及诊断符合率。

观察组患者术前斜疝诊断阳性的CRP水平明显高于对照组（P<0.05）。对照组患者的腹股沟斜疝阳性检出率为80.00%（24/30），稍低于观察组的86.67%（26/30）（P>0.05）。观察组患者的腹股沟斜疝诊断与手术结果相符合的阳性率为100%，稍高于对照组的93.33% （P>0.05）。观察组患者的准确度为100%、特异度为50.00%、灵敏度为92.31%、阴性预测值为50.00%、阳性预测值为92.31%，均稍高于对照组的93.33%、42.86%、86.96%、50.00%、83.33%（P>0.05）。

彩超检查可提高腹股沟疝的诊断准确性，还可密切观察病情变化，为临床诊治提供参考依据。CRP作为炎症的一种非特异性指标，对腹股沟嵌顿疝的鉴别诊断提供较好的依据。

To analyze the clinical significance of color Doppler ultrasonography combined with c-reactive protein (CRP) in the diagnosis of incarcerated inguinal hernia.

A total of 60 patients with inguinal hernia admitted to Fuyang Fifth People's Hospital from March 2017 to March 2020 were selected as the study subjects. Inguinal hernia in the control group (30 cases) was diagnosed by color ultrasound combined with CRP, and incarcerated inguinal hernia in the observation group (30 cases) was diagnosed by color ultrasound combined with CRP. CRP levels in the two groups were analyzed and observed. The diagnostic efficacy and the diagnosis coincidence rate of the two groups of patients were analyzed.

The preoperative positive CRP level of patients with an inguinal hernia diagnosis in the observation group was significantly higher than that in the control group (P<0.05). The positive rate of indirect inguinal hernia in the control group was 80.00% (24/30), slightly lower than the 86.67% (26/30) in the observation group, and there was no significant difference (P>0.05). The positive rate of indirect inguinal hernia diagnosis in the observation group was 100%, slightly higher than that in the control group (93.33%), with no significant difference (P>0.05). The accuracy, specificity, sensitivity, negative predictive value and positive predictive value of the observation group were 100%, 50.00%, 92.31%, 50.00% and 92.31%, which were slightly higher than those of the control group (93.33%, 42.86%, 86.96%, 50.00% and 83.33%). There was no significant difference (P>0.05).

Color doppler ultrasonography can improve the accuracy of inguinal hernia diagnosis and closely observe the changes in the disease, providing reference for clinical diagnosis and treatment. As a non-specific indicator of inflammation, CRP provides a good basis for differential diagnosis of inguinal incarcerated hernia.
