Pediatric Duodenal Stenosis

  • Etiology: congenital failure of recanalization
  • 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

Radiology 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.

Surgery Cases of Duodenal Stenosis

Surgical image of duodenal stenosis
Surgical image shows a massively dilated second part of the duodenum in the center of the image. The decompressed proximal jejunum, being pinched between the thumb and forefinger, is seen to the left and inferior to the dilated duodenum.
