Duodenal atresia

Definition:

Duodenal atresia is a condition in which the duodenum (the first part of the small bowel) has not developed properly. It is not open and cannot allow the passage of stomach contents.

Causes, incidence, and risk factors:

The cause of duodenal atresia is unknown, but it is thought to result from problems during the developmental stage in which the embryo's duodenum normally changes from solid to tube-like (recanalization).

Duodenal atresia is present in more than 1 in 10,000 live births. Approximately 20-30% of infants with duodenal atresia have Downs syndrome. Duodenal atresia is often associated with other congenital abnormalities.
