Congenital duodenal atresia

Intestinal atresia is a congenital defect of a hollow organ that causes complete luminal obstruction and can occur anywhere in the digestive tract, most commonly affecting the ileum. Intestinal atresia affecting the duodenum is called congenital duodenal atresia. This condition is more common in premature infants. The main symptoms include vomiting shortly after birth (a few hours to 2 days) and failure to pass meconium.
