Intussusception in preterm infants: case report and literature review

Intussusception is an extremely rare disorder in preterm infants. An infant of 29 weeks gestational age with this condition is reported and a retrospe ctive analysis of 17 previously reported cases presented. In the reviewed p reterm infants, risk factors for intussusception seemed to be multifactoria l. Clinical features included severe abdominal distension (17/17), gastric aspirates (13/17), commonly bilious, bloody stools (10/17) and rarely a pal pable abdominal mass (5/17). Diagnostic features were signs of small bowel obstruction on the abdominal radiographs. Signs and symptoms were similar t o those seen in necrotizing enterocolitis, therefore difficulties in establ ishing a correct diagnosis led to an average delay of 7 days between the on set of symptoms and abdominal surgery, increasing the risk of developing a compromised bowel. Conclusion The differential diagnosis of an intussusception should be consi dered in preterm infants with acute abdominal distension and tenderness.
