Retrospective study of 255 patients with ischemic colitis

This paper compares different radiologic and endoscopic manifestations of ischemic colitis in the various stages. Of 255 patients with various stages of ischemic colitis, barium enema examinations were performed in 33% of those studied radiologically, and colonoscopy was performed in 26% of those studied endoscopically. Thumbprinting (submucosal edema/hemorrhage) and/or transverse ridging were more frequently seen (69% and 59%, respectively, of patients studied radiologically and endoscopically) in the early stage (1-7 days) of colonic ischemia, but we also occassionally found late manifestations (after 14 days) of thumbprinting (22% and 27%, respectively)
