Rome Criteria for IBS: When Is Further Testing Needed?  Medscape

Does knowing the diagnostic criteria necessarily lead to sound clinical decision-making? Not always. A recent study published in Neurogastroenterology & Motility evaluated medical students from 14 Latin American countries, including Brazil, and found that although most were familiar with the Rome Criteria for disorders of gut-brain interaction (DGBI), many still relied on a diagnosis of exclusion rather than a positive diagnosis. Researchers at the University of Miami in Miami found that this approach persisted even among students who had received formal training in DGBI.

DGBI is characterized by gastrointestinal symptoms related to combinations of altered motility, visceral hypersensitivity, and changes in mucosal function, gut microbiota, or central nervous system processing.

The Rome Criteria are an international consensus framework developed by the Rome Foundation, with inputs from more than 140 experts from 27 countries. They used clinical symptoms to support a positive diagnosis without requiring extensive testing to exclude other diseases.

Article Key Points

• Rome Criteria support positive IBS dx; extensive routine testing rarely changes diagnosis.

• 238 Latin American students: 74% DGBI teaching, 69% knew Rome Criteria.

• Despite no warning signs, 70% ordered initial tests; 53% still tested after normal labs.

• ~1/3 misclassified functional symptoms as warning signs; knowledge ≠ clinical reasoning.

• Limited initial workup: CBC, CRP, celiac serology; calprotectin/colonoscopy if indicated.
