Nun-ulcer dyspepsia (NUD) is a very common disorder: about 30% of subjects may suffer from this syndrome, with a subsequent increase in sanitary cost. NUD is diagnosed by means of both an accurate anamnesis and instrumental investigations like double-contrast upper gastrointestinal X-rays, endoscopy, and US of the biliary tract. Our study was aimed at evaluating the actual capabilities of double-contrast radiology in the characterization of NUD patients. One-hundred consecutive outpatients (53 males and 47 females, age range 15-84 years) with clinical symptoms of NUD were submitted to double-contrast gastric radiological examination. X-rays were performed without pharmacological hypotonicity to better depict functional disorders (i.e., impaired esophageal motility, gastroesophageal and duodenogastric reflux, gastric hypotonicity, and delayed gastric emptying) even though this prevented the though evaluation of morphological features, which are better identified by gastrointestinal endoscopy. 42% of patients, especially middle-aged ones, exhibited only functional disorders. Double-contrast X-rays might therefore be suggested as a useful investigation technique in young patients with clinical symptoms of NUD: it is capable of showing functional disorders and therefore can support upper gastrointestinal tract endoscopy in the pathophysiological characterization of NUD patients.
