PY - 2018 T2 - Rudolph's Pediatrics, 23e AB - Congenital intestinal atresias, stenosis, and webs typically present early in neonatal life due to the associated obstructive symptoms. The reported incidence of congenital intestinal atresias, stenosis, and webs is 1 in 5000 to 10,000 births in the United States. These malformations can occur throughout the intestinal tract but are most commonly found in the duodenum (50%) and the jejunum or ileum (35–40%). A colonic location is identified in 5% to 10% of atresias, and rarely, pyloric or gastric lesions are present (< 1%).
