Definition
Duodenal atresia is a condition in which the first part of the small bowel (the duodenum) has not developed properly. It is not open and cannot allow the passage of stomach contents.
Overview, Causes, & Risk Factors
The cause of duodenal atresia is unknown, but it is thought to result from problems during an embryo’s development in which the duodenum does not normally change from a solid to a tube-like structure.
Duodenal atresia is seen in more than 1 in 10,000 live births. Approximately 20-30% of infants with duodenal atresia have Down syndrome. Duodenal atresia is often associated with other birth defects.
