To explore the clinical value of multi-slice spiral CT multi-plane reconstruction in the differential diagnosis of inguinal hernia.

A retrospective analysis was performed on 100 patients who received simultaneous multi-slice spiral CT multi-plane reconstruction and hernia repair in Inner Mongolia Baotou Iron and steel hospital from February 2020 to February 2021. The imaging signs, types and occurrence sides of hernia were observed, and the surgical results were considered as the gold standard. To analyze and compare the accuracy, sensitivity, specificity, negative and positive predictive value of multi-slice spiral CT multi-plane reconstruction in the diagnosis of inguinal hernia.

There were 116 hernia sacs in 100 patients. The sensitivity and specificity of multi-slice spiral CT multi-plane reconstruction in the diagnosis of indirect inguinal hernia was 93.33% and 94.44%, and the negative and positive predictive values were 92.73% and 94.91%, respectively. The above indexes of direct inguinal hernia were 91.67%, 95.65%, 96.70% and 89.19%, respectively. The above indexes of femoral hernia were all 100%. Multi-slice spiral CT examination showed that femoral hernia sac was located below after the inguinal ligament, with triangle tamponade. The indirect inguinal hernia and direct hernia sac were located above before the inguinal ligament, without triangle tamponade, but the indirect inguinal hernia sac was located lateral to the inferior epigastric artery, direct hernia sac was located medial to the inferior epigastric artery, with lateral crescent.

Indirect inguinal hernia, direct inguinal hernia and femoral hernia have characteristic imaging features. Multi-slice spiral CT multi-plane reconstruction can reveal the anatomical details of the inguinal region, which is of great value in the diagnosis and differential diagnosis of indirect, direct inguinal hernia and femoral hernia.
