Ultrasonographic Diagnosis of Intussusception in the Emergency Department

Abstract

Distinguishing life-threatening causes of vomiting and diarrhea in infants is challenging. The ability to quickly and accurately differentiate causes of the acute abdomen at the bedside without radiation exposure is an extremely valuable skill. Ultrasound is quickly becoming first line for many differentials of the acute abdomen including intussusception, appendicitis, and pyloric stenosis. Volvulus and mesenteric adenitis can also often be seen. This report details a case of pediatric intussusception diagnosed in the emergency department by emergency medicine clinicians. Additionally, we review the best technical approach to finding an intussusceptions using ultrasound. The sensitivity and specificity of ultrasound for intussusception approaches 100% with an experienced sonographer. Harnessing this skill has the potential to save a significant amount of time and lives.
