Answer

Ultrasonography is certainly valuable in the diagnosis of a hernia and can be used to determine the contents of a hernia. [20]  One study that used computed tomography (CT) as the criterion standard showed a moderate sensitivity and high specificity for ultrasonographic diagnosis of incisional hernias. [21]  A smaller case review found ultrasonography less useful in children. [22]

Ultrasonography has been advanced as an aid to hernia reduction. [23, 24, 25]  By assisting in reduction, it may reduce the rate of emergency repair for incarcerated hernias. [24]  The reasoning is that the ultrasound probe should be able to help locate the fascial defect, as well as the tissue to be reduced, and may give the operator a better grasp on the forces needed for reduction.
