Abstract Objective: To investigate the value of CT in differentiating small bowel ischemia from infarction in patients with adhesive small bowel obstruction(ASBO). Methods: According to operative results, thirty-seven patients with ASBO were classified into ischemia group and infarction group. The CT findings of two groups were retrospectively compared and analyzed. Results: The incidence of bowel wall pneumatosis, mesenteric haziness, decreased enhancement of bowel wall, decreased enhancement of mesenteric arteries and veins of on CT imaging in the infarction group was statistically higher than that in the ischemia group, with odds ratio for infarction of 3.78, 11.91, 10.15, 16.50, and 19.55, respectively. The positive predictive value of a combination of 4 or more CT findings for small bowel infarction was 83.3%(10/12). Conclusion: CT imaging finding is helpful in differentiating small bowel ischemia from infarction in patients with ASBO, and decreased enhancement of mesenteric veins is the most valuable CT findings.
