BACKGROUND: The diagnosis and treatment of intussusception is often confusing in infants aged younger than 3 months. This study aimed to discuss the particularity of diagnosis and treatment of intussusception in this age group. METHODS: From April 1983 to June 2008, 39 infants aged 3 months or younger who had been diagnosed with intussusception were treated and their clinical data were analyzed retrospectively. RESULTS: Of the 39 infants (29 boys and 10 girls), ages ranged from 12 hours to 3 months, with a mean age of 52.6 days. The duration from onset to admission ranged from 7 to 142 hours (mean 39.6 hours). Three infants had intrauterine intussusception and 36 postnatal intussusception. The 3 infants with intrauterine intussusception had typical presentations of complete ileus after birth. Gap type ileal atresia was found in surgery in 2 of the 3 infants and primary anatomosis was performed therapeutically. The other infant was found to have ileal separation and a patent proximal end with diffused meconium peritonitis. The patient died 2 days after primary anastomosis. Most infants with postnatal intussusception had two or more manifestations of the tetralogy, namely intermittent screaming, vomiting, bloody stool, and abdominal mass. In 23 infants who underwent pneumatic reduction, 17 had a successful reduction and 6 converted to open surgery. Surgery was indicated for 19 infants, with maneuver procedure in 14. Meckel's diverticulum was noted as a leading cause in 2 infants, ileal duplication in 1 with necrosis of intussusceptum, and primary intussusception with lead point necrosis in 2. The 5 infants, on whom segmental resection was performed, underwent primary anastomosis. All infants with postnatal intussusception had a smooth recovery. CONCLUSIONS: Infants aged 3 months or younger may suffer from intussusception and most of them present with typical symptoms. Early diagnosis and treatment are needed for a good prognosis. Intrauterine intussusception may be an etiological factor for ileal atresia.
