Vomiting after first 24 hours of life

Bilious Vomiting after first 24 hours of life is a sign of intestinal obstruction below the second part of duodenum.
Common causes: intestinal stenosis AND atresia.
Jejunal, ileal, colonic atresias are caused by vascular accident in utero.

There was decreased intestinal perfusion which leads to an ischemia of a segment of bowel, and than subsequent narrowing or even obliterating of the lumen.

Common affected intestinal part is ileum.

When occluded a major vessel (SMA), then there is a large area of an intestinal wall necrosis.
