Duodenal atresia is the congenital absence or complete closure of a portion of the lumen of the duodenum.

Associated conditions

Approximately 20–40% of all infants with duodenal atresia have Down syndrome.[citation needed]. Approximately 8% all infants with Down syndrome have duodenal atresia.[1]

It is also associated with polyhydramnios, which is increased amniotic fluid in the uterus.[1]

Diagnosis

The diagnosis of duodenal atresia is usually confirmed by radiography. An X-ray of the abdomen shows two large air filled spaces, the so-called "double bubble" sign.[2][3] The air is trapped in the stomach and proximal duodenum. Since the closure of the duodenum is complete in duodenal atresia, no air is seen in the distal duodenum.

Atresias distal to the duodenum are usually caused by vascular accidents or ischemic insult, such as jejunoileal atresia.
