investigations and treatment

Last reviewed 01/2018

Duodenal atresia should be investigated by:

• electrolyte and acid-base status measures, e.g. U&E's, blood gases, with subsequent correction of abnormalities
• plain abdominal X-ray: this may show a 'double bubble' sign of duodenal obstruction
• barium study may show stenosis

Treatment involves surgical correction via a duodenojejunostomy with resection of the atretic section.
