[edit] Discussion

  • Shock bowel is reversible small bowel ischemia related to hypovolemia.
  • Hypoperfusion results in increased bowel permeability to macromolecules and albumin which leads to
    • Diffuse bowel wall thickening
    • Increased enhancement on CT scans due to slowed perfusion and interstitial leakage of molecules of contrast material
    • Accumulation of intraluminal fluid secondary to the failed resorption capacity.
  • Shock bowel resolves with resolution of hypovolemia; this fact suggests that this finding represents a reversible ischemic change without clinical significance.

  • Mild to moderate diffuse small-bowel thickening and marked hyperenhancement of the mucosa.
