To explore the role of color high-frequency probe combined with dual position scanning in the diagnosis of inguinal hernia, and to analyze the imaging characteristics of such lesions.

The data of 90 patients who underwent inguinal hernia surgery in the Department of General Surgery of Lujiang County People's Hospital from January 2019 to January 2022 were retrospectively analyzed. According to different color ultrasound diagnosis methods, the patients were divided into two groups: 42 patients with low-frequency probe combined with dual position scanning as the control group, and 48 patients with high-frequency probe combined with dual position scanning as the observation group. The distribution of surgical results in the 2 groups was described. With the surgical results of the patients as the gold standard, the diagnostic accuracy of inguinal hernia and complications of the two groups was analyzed. The ultrasonographic features of inguinal hernia were described.

The surgical results of the two groups showed that there were 20 cases of direct hernia, 52 cases of indirect hernia, 14 cases of indirect hernia combined with direct hernia, and 4 cases of femoral hernia. There was no statistical difference in the distribution of inguinal hernia between the two groups (P>0.05). The overall diagnostic accuracy in the observation group was higher than that in the control group (P<0.05). In the classification of various inguinal hernias, the diagnostic accuracy of indirect hernia in the observation group was higher than that in the control group (P<0.05). There was no statistically significant difference in the diagnostic accuracy of direct hernia, indirect hernia combined with direct hernia, and femoral hernia between the two groups (P>0.05). The overall diagnostic accuracy of inguinal hernia complications in the observation group was higher than that in the control group (P<0.05). There was no statistical difference in the diagnostic accuracy of simple inguinal hernia, combined with spermatic lipoma and combined with hydrocele between the two groups (P>0.05).

Both high-frequency color ultrasound and low-frequency color ultrasound combined with different body scanning position can achieve good detection results for inguinal hernia. High-frequency color ultrasound is more accurate in diagnosing inguinal hernia and its complications. It can be selected according to the actual situation in clinical practice.
