Aims: To assess the safety, sensitivity and specificity of out-patient herniography when used to diagnose hernias in the presence of a normal or equivocal physical examination.
Materials and methods: This retrospective study reviewed the symptoms, clinical findings, radiological findings, surgical findings and clinical outcome of 112 patients referred for herniography over a 5-year period.
Results: No significant complications were encountered. Thirty hernias were diagnosed. There was one false-positive and one false-negative examination giving herniography a sensitivity of 96.6% and a specificity of 98.4%.
Conclusion: Herniography is a sensitive, specific, safe and reliable investigation which should be available to and used by all surgeons who perform hernia repair operations.
