The pediatric surgeon should be consulted immediately since this is a life-threatening emergency. The initial imaging examination is plain films of the abdomen. If the patient clinically or radiographically is suspicious for intussusception, the next examination is an enema study. Air or fluid (Hypaque) may be utilized as contrast, and the examination may be therapeutic as well as diagnostic if the hydrostatic pressure exerted by the enema procedure successfully reduces the visualized area of bowel intussusception. Successful reduction occurs up to 90% of the time. Further imaging, if necessary, should be performed after consultation with the pediatric radiologist.
