Jejunal Stenosis

Etiology: vascular in origin 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

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).

Surgical image of jejunal web — Surgical image shows an abrupt caliber change in the proximal jejunum.

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.
