As a modification of the double-contrast barium meal, a tubeless radiological test for duodenogastric reflux, not involving the administration of any pharmacologically active substances, is described. The procedure minimizes the possible occurrence of artefacts. It allows for the examination of duodenogastric reflux in relation to both duodenal and pyloric motility. Previously much emphasis has been laid on the role of duodenal contraction waves, but the results show that the dynamic state of the pyloric sphincteric cylinder may be of greater importance, as reflux only occurred while this structure was relaxed or partially contracted. The test can be used on a routine basis in pathological conditions (such as gastric ulceration) and may help to clarify some of the controversial aspects of duodenogastric reflux. The findings in 14 normal controls and in 100 patients are described.
