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.
