[The role of ultrasonography in abdominal pain in children in the emergency room].

Our retrospective study aims at defining the influence of ultrasonography on the management of acute abdominal pain in a pediatric population. This technique appears to be essential in the diagnosis of intussusception and thus, should be recommended in all cases of acute abdominal pain in the population at risk for this disorder. On the other hand, ultrasonography only plays a minor role in the management of the other diseases we observed, especially in acute appendicitis.
