Lethargy as a presenting symptom in patients with intussusception.

The author's experience with lethargy in pediatric patients with intussusception was reviewed retrospectively over a 10-year period and proved to be a symptom elicited on admission in half of the patients. The results indicate that lethargy is an important symptom in patients with intussusception when occurring in association with vomiting, melena, or a palpable abdominal mass, or all three.
