Abstract
Barium studies of the upper gastrointestinal tract and small bowel were performed in 16 adult patients with biopsy-proven nontropical sprue. Commercially available contrast media containing micropulverized barium sulfate, suspending agents, and various other additives were used. Radiographs were analyzed for the incidence and pattern of duodenal vs. small-bowel changes associated with celiac disease. Thirteen of 16 patients (81%) demonstrated abnormalities of the duodenum which ranged from focal erosions to diffusely thickened and nodular folds. A nonspecific, mild dilatation pattern was present on the small-bowel series of 11 patients (69%). The classic radiographic signs of malabsorption, such as flocculation and segmentation, however, occurred in less than 20% of cases, apparently because of the stability of new barium suspensions. The pathogenesis of duodenal changes in sprue and its diagnostic implications are emphasized.
