"Patients present in early life with duodenal obstruction and associated symptoms of abdominal distension, vomiting and absent bowel movements. In complete atresia, duodenum ends blindly with no communication with the distal bowel (and therefore no aeration distally). The atretic segment is usually just distal to the ampulla of Vater 1 and the child has bilious vomiting. If the atresia is proximal to the ampulla, the vomiting is non-bilious."
"Recognition that these structures are not continuous with the stomach will aid in the correct interpretation. This may occur in cases of choledochal cysts or renal, hepatic, omental, duplication or ovarian cysts. Likewise, a "double bubble" may be seen in cases of Ladd's bands, annular pancreas or volvulus, in which there is no duodenal atresia."
