- Abstract: Objective To analyze the application value of multi-slice spiral CT(MSCT)in the preoperative diagnosis and classification of inguinal hernia.Methods The clinical data of 130 patients with inguinal hernia admitted to our hospital were collected,and all patients underwent inguinal hernia repair.MSCT examination was conducted for the inguinal hernia of the patients,and the efficacy of MSCT in the diagnosis of different types of inguinal hernia was explored by taking the intraoperative diagnosis results as the gold standard.The contents of the hernia sac in patients with different types of inguinal hernia were analyzed,and the accuracy of MSCT under different scanning directions on the relationship between neck of hernia sac and inferior epigastric artery was analyzed.Results The intraoperative diagnosis results confirmed that there were 92 cases of oblique hernia,26 cases of direct hernia and 12 cases of femoral hernia among 130 patients with inguinal hernia.A total of 139 hernia sacs were present,with 121 unilateral and 9 bilateral hernia sacs.Among patients with oblique hernias,87 cases were unilateral and 5 cases were bilateral;among patients with direct hernias,23 cases were unilateral and 3 cases were bilateral;among patients with femoral hernias,11 cases were unilateral and 1 case was bilateral.The MSCT scan results showed that patients with oblique hernia,direct hernia and femoral hernia were 92 cases,26 cases and 12 cases respectively.The sensitivities of MSCT in diagnosing oblique hernia,direct hernia and femoral hernia were 95.65%,84.62%and 100%respectively,and the specificities were 89.47%,96.15%and 100%respectively.The contents of the hernia sac in oblique hernia were mainly small intestine and mesentery,while those in direct hernia and femoral hernia were mainly small intestine and fat.The proportions of fat and bladder in the contents of the hernia sac of direct hernia were higher than those of oblique hernia and femoral hernia(P<0.05).The proportion of mesentery in the contents of the hernia sac of oblique hernia was higher than that of direct hernia and femoral hernia(P<0.05).According to the relationship between hernia sac neck and inferior epigastric artery,the diagnostic accuracy of inguinal hernia by MSCT under coronal scan was the highest.Conclusion The sensitivity and specificity of MSCT in the preoperative differential diagnosis of inguinal hernia are relatively high,and the accuracy of MSCT in classification diagnosis can be improved if combined the contents of the hernia sac and the relationship between the hernia sac neck and inferior epigastric artery.
