Patients with symptoms at the site of a previous inguinal hernia repair may constitute a diagnostic dilemma. The usefulness of herniography in the assessment of these patients was evaluated at 54 symptomatic sites in 46 subjects. Ten persistent or recurrent hernias were shown by herniography, only 2 of which were definitely detected on physical examination. The herniogram was normal at 44 sites, of which, on physical examination, 5 were equivocal and 1 was diagnosed as a definite hernia. On the unoperated-on or asymptomatic side, a total of 14 hernias were shown herniographically. Of these hernias, 8 were not detected on physical examination. Herniography was found to be more sensitive than physical examination in detecting hernias at the symptomatic, previously operated-on sites, as well as at the unoperated-on or asymptomatic sites. When a herniogram provides corroborative evidence that hernia has not recurred, the need for reexploration may be eliminated.
