Radiographic features in ischemic jejunoileitis: serial changes and comparison with pathologic findings.

Serial radiographic examinations of the small intestine, including double-contrast studies, were performed in 13 patients with ischemic jejunoileitis, nine with the stricturing form and four with the transient form. Thumbprinting was observed in five (38%) patients and thickening of the folds in four (31%) at the acute stage of the disease. Tubular narrowing with irregular contours and dilated proximal bowel was observed in six (46%) patients and appeared on day 27 or later. Pathologic findings of the resected specimen in eight patients with the stricturing form revealed annular stricture with relatively shallow ulcers; the irregular contours of the tubular narrowing on radiographs were consistent with a granular or nodular appearance and/or multiple fissures on pathologic study. Eccentric deformity and sacculation were demonstrated in only one patient with the stricturing form. In addition, double-contrast study revealed small ulcers in three (23%) patients. Our results indicate that radiographic findings accurately reflect the clinical course and pathologic findings in this disease.
