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.
