AimsUltrasound is a non-invasive, non-ionising radiation modality which is highly successful at soft tissue imaging. Groin pain from an occult hernia can be a difficult clinical diagnosis made easier by good imaging. The aim of this study was to demonstrate the accuracy of ultrasound in diagnosing and typing the groin hernia, which could lead to its justification of use in the imaging of the occult hernia.Patients And MethodsA total of 118 patients with a clinical diagnosis of a groin hernia, prospectively underwent a blinded, ultrasound examination of the groin. All patients underwent surgery and these findings were compared with the ultrasound results.Results120 symptomatic groins in 118 patients underwent surgery. Ultrasound diagnosed 118 hernias and there were two normal ultrasound examinations. Surgery confirmed the same two patients to be normal - ultrasound sensitivity for all hernias was 100% with 100% specificity. Two femoral hernias were seen in this study, both correctly identified at ultrasound. Of the inguinal hernias, ultrasound identified 36 of 42 direct hernias (sensitivity 86%, specificity 97%) and 72 of 74 indirect hernias (sensitivity 97%, specificity 87%)ConclusionsThis study confirms that ultrasound can accurately diagnose groin hernias and this may justify its use in the assessment of the occult hernia.
