Childhood functional gastrointestinal disorders: child/adolescent.

Area of Science:

• Pediatric Gastroenterology
• Functional Gastrointestinal Disorders
• Diagnostic Criteria Development

Background:

• The Rome II criteria for pediatric functional gastrointestinal disorders (FGIDs) were established in 1999.
• Previous criteria required updates to reflect current clinical understanding and research.

Purpose of the Study:

• To update and revise the pediatric criteria for FGIDs for children aged 4-18 years.
• To establish consensus-based criteria using clinical experience and literature review.

Main Methods:

• Consensus development by the Rome III Committee.
• Review of existing literature and clinical experience.
• Evidence-based revisions where possible, supplemented by clinical judgment.

Main Results:

• The Rome III criteria address cyclic vomiting syndrome, rumination, aerophagia, abdominal pain-related FGIDs, functional constipation, and fecal incontinence.
• New definitions include adolescent rumination and functional constipation.
• Key changes include reduced symptom duration for noncyclic disorders (2 months) and modified criteria for functional abdominal pain.

Conclusions:

• The Rome III pediatric criteria represent an evolution from Rome II.
• These updated criteria are expected to benefit clinicians and researchers in managing childhood FGIDs.
• Future research will likely lead to further modifications of pediatric FGID criteria.
