Sx: Newborn with bilious vomiting, down syndrome, and maternal polyhydramnios, classic double-bubble sign – gaseous distention of the stomach and enlarged duodenal bulb or mega bulb. No intestinal gut is seen distal to the duodenum.
Without distal bowel gas = duodenal atresia??
Duodenal atresia, also known as duodenojejunalatresia, is the congenital absence or complete closure of a portion of the lumen of the duodenum. It causes increased levels of amniotic fluid during pregnancy (polyhydramnios) and intestinal obstruction in newborn babies.
