Groin hernia repairs are the most frequently performed surgical procedures in the United States. The lifetime rate of inguinal hernia is 27% in men and 3% in women.1,2 The risk of inguinal hernia increases with age; the frequency of groin hernia repair, a surrogate for the prevalence of hernia, increases from 0.25% at age 18 years to 4.2% at age 75 to 80 years.3 The diagnosis of groin hernia is usually made on physical examination. Ultrasonography can be helpful in clinically occult cases or to help differentiate inguinal from femoral hernia, but there is significant variability in interpretation. Dynamic computed tomography (CT) or magnetic resonance imaging can resolve controversial ultrasonography findings.4
