Clinical presentation and radiographic identification of small bowel rupture following blunt trauma in children.

The incidence of significant intraabdominal injuries from blunt trauma in children is low (1-8%); however, a missed intestinal laceration may result in a devastating, if not morbid, consequence. We present retrospective case studies of eight children with intestinal lacerations following blunt trauma. Each patient has a unique anatomic defect with misleading initial laboratory and radiographic studies. We did not find a single laboratory or roentgenographic study to be consistently reliable for diagnosis of hollow viscus laceration. The combination of a high index of suspicion and serial abdominal examinations, coupled with subsequent comparative laboratory and radiographic evaluations, proved most reliable in identifying patients with intestinal injury.
