Jejunal Stenosis and Jejunal Web

  • Etiology: in-utero vascular accident so it has no other associated congenital abnormalities
  • UGI: jejunum is dilated while ileum is decompressed
  • Clinical: less severe form of jejunal atresia which often results in a delayed diagnosis but still requires surgical correction, much less common than jejunal atresia

Radiology Cases of Jejunal Stenosis

UGI of jejunal stenosis
Delayed image from an upper GI with small bowel follow through exam shows the jejunum to be extremely dilated (left side of image) while the ileum is decompressed (right side of image).

Surgery Cases of Jejunal Stenosis

Surgical image of jejunal stenosis
Surgical image shows the two retractors outlining a markedly dilated duodenum in the center of the image. The proximal jejunum is markedly stenotic where it joins to the duodenum at the duodenal-jejunal junction in the center of the image. The more distal jejunum is normal in caliber.
