[Contribution of digestive system ultrasonography in the assessment of abdominal pain in children].

The quality of modern ultrasonography allows to study not only solid abdominal organs but also digestive walls and abdominal lymphnodes, leading to accurate diagnosis in many cases, and decreasing the use of more aggressive radiological procedures (upper GI baryum studies, baryum enema, intravenous pyelography, etc.). In dealing with abdominal pain in children, the plain XRay film of the abdomen and abdominal echography are performed immediately after history taking and physical examination, and are equally important in the work up of these cases.
