Duodenal Atresia

Upper gastrointestinal series showing complete obstruction to the flow of contrast at the second portion of the duodenum. There is also contrast filling of the biliary tree above the duodenal bulb noted (arrow).


Duodenal atresia (DA) occurs in approximately 1 in 2500–7500 live births without a sex-associated difference. Approximately 25–40% of infants with duodenal atresia have Trisomy 21. Approximately 8% of infants with Down syndrome have duodenal atresia. There is also an association of VACTERL anomalies (vertebral, anorectal, cardiac, tracheoesophageal, renal, and limb anomalies).

 ICD-11 LB14 Structural developmental anomalies of duodenum - Any congenital defect of duodenum that results from interference with the normal growth and differentiation of the fetus. Such defects can arise at any stage of embryonic development, vary greatly in type and severity, and are caused by a wide variety of determining factors, including genetic mutations, chromosomal aberrations, teratogenic agents, and environmental factors. Most developmental defects are apparent at birth, especially any structural malformation, but some becomes evident later.
