Abstract
Significant changes on a standard barium follow-through examination in celiac disease have been determined by comparison with functional changes (irritable bowel syndrome), malabsorption without a villous lesion (chronic pancreatitis), and a villous abnormality without malabsorption (dermatitis herpetiformis). Patients with iron deficiency anemia formed the control group. Slight jejunal dilatation (26–30 mm) was found in 15% of the celiacs and 17% of the irritable bowel patients. Dilatation in excess of 30 mm and/or effacement of jejunal fold pattern occurred only with an abnormal jejunal biopsy, in 54% of the celiacs and 33% of the dermatitis herpetiformis patients. Patients with malabsorption by itself and 46% of the celiacs could not be distinguished from those with irritable bowel syndrome. The concept of a malabsorption pattern is considered invalid, and the diagnosis of celiac disease can be reliably established only by peroral jejunal biopsy.
