Duodenal Stenosis

  • Etiology: congenital
  • AXR: air fluid levels in stomach and duodenal bulb with distal bowel gas
  • UGI: narrowing after first portion of duodenum
  • Clinical: less severe form of duodenal atresia which often results in a delayed diagnosis but still requires surgical correction

Cases of Duodenal Stenosis

AXR and UGI of duodenal stenosis
AXR (above) shows the tip of the nasogastric tube within a very dilated duodenal bulb. There is extensive distal bowel gas. Spot image from an upper GI exam (below) shows a fixed area of narrowing between the first and second portions of the duodenum through which contrast passed slowly.
