Jejunal and ileal atresia are caused by in utero vascular insults, leading to poor recanalization of distal small<unk>  segments, a condition in which surgical resection and reanastamosis are mandatory. Hirschsprung disease is due to an arrest in neural cell ganglia, leading to absent innervation of a segment distal<unk> , and appears as a massively dilated segment of distal<unk>  on contrast enema. Surgical resection is necessary for this condition as well. Imperforate anus also requires surgical management, with the diagnosis made by inability to pass the rectal tube through the anal sphincter. Supportive intravenous hydration, gastric decompression, and ventilatory support may be needed due to poor neonatal nutrition resulting from dysfunctional<unk>  absorption.
