The role of ultrasound in the management of patients with occult groin hernias

Abstract

Ultrasound is poor in diagnosing occult groin hernias with a PPV of 70% suggesting a 30% chance of negative groin exploration. The equivocal ultrasound group requires careful follow-up as a considerable number were later diagnosed with hernia. The absence of subsequent hernia diagnosis in the negative ultrasound group suggests it may be a useful rule-out test to exclude occult groin hernias in symptomatic patients.
