A DUAL-TRACER METHOD FOR STUDYING INTRAGASTRIC DISTRIBUTION AND GASTRIC-EMPTYING OF SOLIDS AND LIQUIDS IN FUNCTIONAL DYSPEPSIA

Twenty-five patients with functional dyspepsia and 11 healthy controls matched for age and sex were examined. The patients were divided into two groups: patients with dysmotility-like symptoms and those with ul cer-like symptoms. In a dual-tracer gastric emptying study, dysmotilit y-like and ulcer-like symptoms could not be distinguished from each ot her on the basis of gastric emptying times. The intragastric distribut ion and the solid lag time in dysmotility-like dyspepsia differed sign ificantly from those of the controls.
