Transient postprandial ischemia is associated with increased intestinal fatty acid binding protein in patients with chronic gastrointestinal ischemia.

Background: Chronic gastrointestinal ischemia (CGI) is still a difficult diagnosis to make. Currently, the only diagnostic with an acceptable sensitivity for actual mucosal ischemia is gastrointestinal tonometry. However, tonometry is a cumbersome and invasive diagnostic test.
