Gastric emptying time in cyclic vomiting syndrome in children

Abstract. – Pathogenesis of cyclic vomiting syndrome (CVS) is still uncertain. Aim of our study has been to verify the role of gastric emptying time in children affected by CVS. We studied 9 children with CVS who underwent measurement of gastric emptying time by real-time ultrasonography after administration of a mixed, solid-liquid meal. In all the children gastric emptying time resulted in normal range. Our data suggest that mobility abnormalities of the stomach don’t play a key role in the pathogenesis of CVS.
