(See also Congenital abnormalities of the gastrointestinal tract in the overview.) The duodenum may be displaced by an atresia, stenosis and compression by extraluminal soft tissue masses. Duodenal atresia This anomaly is the third most common atresia of the GIT. The estimated incidence is 1 of 5000 to 10,000 live births. The atresia of the duodenum caused by the lack of canalization of the duodenum in the embryo. This error may be due to an ischemic event or genetic factors. Duodenal atresia is unlike other atresia often associated with other congenital abnormalities such as Down syndrome, which is present in 25 to 40% of cases. Other associated anomalies include VACTERL (Vertebral Anomalies, Anal atresia, Cardiac Malformations, tracheoesophageal fistula, Esophageale atresia, Renal Anomalies and radial aplasia, Limb Anomalies), malrotation, pancreas annular, abnormalities of the bile duct and ? ? mandibulofaziale anomalies.
