Clinical Approach to Functional Gastrointestinal Disorders in Children: Revolve Around on Cyclic Vomiting Syndrome and Aerophagia

Functional gastrointestinal disorders (FGIDs) are defined as a chronic or recurrent gastrointestinal symptoms not explained by structural or biochemical abnormalities. The Rome II pediatric criteria for FGIDs were announced in 1999. The Rome III criteria, update and revise the pediatric criteria, included FGIDs criteria of infant and toddler to child and adolescent (aged 4 to 18 years). The aerophagia was classified into abdominal pain-related FGIDs in the ROME II criteria. However, cyclic vomiting syndrome and aerophagia, both were classified into vomiting and aerophagia part in the ROME III criteria. We describe the clinical features, diagnostic criteria, and treatments of cyclic vomiting syndrome and aerophaiga among pediatric FGIDs. (Korean J Pediatr Gastroenterol Nutr 2011; 14(Suppl 1): S9∼S18)
