Abnormal duodenal loop demonstrated by X-ray. Correlation to symptoms of dyspepsia

In 73 patients the occurrence of dyspeptic symptoms were correlated with the presence of a normal duodenal loop (29 patients) and an abnormal duodenal loop (44 patients). An abnormal duodenal loop was associated with a significantly higher incidence of symptoms provoked by meals, vomiting, regurgitation, heartburn, and the irritable bowel syndrome.
