Intestinal atresia occurs in around 1 in 3,000 births in the United States. [1] The most common form of intestinal atresia is duodenal atresia. It has a strong association with Down syndrome. [12] The second-most common type is ileal atresia. 95% of congenital jejunoileal obstructions are atresias; only 5% are stenoses. [2]
The common duct then opens medially into the descending part of the duodenum at the major duodenal papilla. The common duct usually measures 2-10mm in length. [1] The ampulla of Vater is an important landmark halfway along the second part of the duodenum marking the transition from foregut to midgut. [citation needed]
The bile duct is some 6–8 cm long, and normally up to 8 mm in diameter. [4]Its proximal supraduodenal part is situated within the free edge of the lesser omentum.Its middle retroduodenal part is oriented inferiorly and right-ward, and is situated posterior to the first part of the duodenum, and anterior to the inferior vena cava.
Frontal view of the abdomen with double bubble sign, patient was found to have duodenal atresia. In radiology, the double bubble sign is a feature of pediatric imaging seen on radiographs or prenatal ultrasound in which two air filled bubbles are seen in the abdomen, representing two discontiguous loops of bowel in a proximal, or 'high,' small bowel obstruction.
Cases without distal gas are usually related to duodenal atresia, while high obstruction with distal gas need an upper gastrointestinal series because of the need to distinguish duodenal web, duodenal stenosis and annular pancreas from midgut volvulus, the latter being a surgical emergency. Confirmation is ultimately by surgical intervention. [6]
