To investigate the application value of color Doppler ultrasound in the differential diagnosis of inguinal hernia and femoral hernia.

The data of 107 patients with inguinal hernia and femoral hernia who were admitted to Lujiang County People's Hospital, Anhui Province from October 2021 to September 2022 were analyzed retrospectively. All patients underwent color Doppler ultrasonography before surgery, and the examination results were analyzed. The value of color Doppler ultrasound in the differential diagnosis of inguinal hernia and femoral hernia was discussed.

All 107 patients were confirmed by surgery including 75 cases of indirect hernia, 20 cases of direct hernia and 12 cases of femoral hernia. Color Doppler ultrasound found 73 cases of indirect hernia, 19 cases of direct hernia and 12 cases of femoral hernia, and 3 cases were misdiagnosed as lipoma. The sensitivity and specificity of color Doppler ultrasound were 96.00% and 96.87% for diagnosing indirect hernia, 95.00% and 96.55% for diagnosing direct hernia, 100.00% and 100.00% for diagnosing femoral hernia .

Color Doppler ultrasound has high sensitivity and specificity for diagnosing inguinal hernia and femoral hernia. It can provide reference for the development of surgical plan and adjustment of details.
