A newborn delivered at 37 weeks gestation and birth weight 2.7 kg, presents at 12 h of life with bilious vomiting. On examination, RR is 36/m, HR is 110/m, CRT is < 3s, and there is abdominal distention. Abdominal radiograph reveals multiple air-fluid levels with absent distal gas pattern. The most likely etiology is:
Jejunal-ileal atresia
Bilious vomiting with multiple dilated bowel loops showing air-fluid levels and absent distal gas on X-ray in the first day of life is classic for jejuno-ileal atresia (a complete mechanical obstruction). Malrotation with volvulus classically shows a 'double bubble' or paucity of distal gas with a more acute/toxic presentation; pyloric stenosis presents later (3-6 weeks) with non-bilious vomiting.
