Diagnosis of Inguinal Region Hernia in Multi-detector Row CT

Objective To assess the value of multi-detector row CT(MDCT)in diagnosis of the inguinal region hernia.Methods The CT images of 96patients with inguinal region hernia from June to December 2009were retrospectively analyzed.The diagnosis and application of coronal and sagittal views in inguinal region hernia were assessed by multi-planer reconstruction.Results Hernia sac in 63indirect hernia patients(66hernias)originated lateral to the inferior epigastric artery enter the inguinal canal through the deep ring,anterior(43/63,68.3%)or anteromedial (15/63,23.8%)to the spermatic cord or round ligament;sac in 30direct hernia patients(37hernias)originated medial to the inferior epigastric artery,medial to the spermatic cord;both indirect and direct hernia sac located anterosuperior to the inguinal ligament;sac in three femoral hernia patients(three hernias)located posterior to the inguinal ligament and inside the radiological femoral triangle of coronal views.Conclusion MDCT plays on important role in diagnosing the inguinal region hernia,and provides critical information for preoperative and intraoperative.
