Recurrent abdominal pain: symptom subtypes based on the Rome II Criteria for pediatric functional gastrointestinal disorders.

Objectives: Recurrent abdominal pain (RAP) is a common childhood complaint rarely associated with organic disease. Recently, the Pediatric Rome Criteria were developed to standardize the classification of pediatric functional gastrointestinal disorders (FGIDs) using a symptom-based approach. The authors tested the hypothesis that most patients with childhood RAP could be classified into one or more of the symptom subtypes defined by the Pediatric Rome Criteria.
