ROLE OF HERNIOGRAPHY IN THE DIAGNOSIS OF OCCULT HERNIAS

Twenty-two patients with groin or incisional pain and normal physical examinations underwent herniography. Eight patients were found to have 11 unsuspected hernias. Seven were direct, two indirect, and two incisional. Six of nine groin hernias were recurrent. Exploration confirmed the herniographic findings in all patients. Follow-up evaluation of patients undergoing herniorrhaphy revealed resolution of symptoms. Ten of the 14 patients with normal herniograms were asymptomatic 3 months after herniography. In these 22 patients, herniography resulted in a savings of $31,000. We conclude that herniography is cost-effective and useful in patients with abdominal wall pain of obscure etiology.
