Duodenal obstruction (DO) is a congenital abnormality which occurs in 1,3 per 10,000 live births and is the small-bowel obstruction most commonly detected during fetal life. Approximately half of the cases are associated with other abnormalities (non-isolated DO), commonly cardiac, vertebral, renal and gastrointestinal such as anal atresia and trachea-esophageal atresia.

Pyloric atresia, or congenital pyloric atresia (CPA) is a very rare congenital anomaly of the gastrointestinal tract where there is a blockage in the gastric outlet at the level of the pylorus.
