Rome II Diagnostic Criteria for Irritable Bowel Syndrome (IBS)
Why Use
The symptoms that define IBS are generally subjective and self-reported, making a classification system helpful. Moreover, there is some evidence to support the notion that patients who meet formal Rome criteria are more likely to respond to some therapies.
When to Use
Patients being evaluated for possible IBS.
Formula
Pearls / Pitfalls
The Rome II Criteria, developed through a literature review and consensus process, defined the diagnosis of Irritable Bowel Syndrome (IBS) until the Rome III and subsequently Rome IV Criteria refined them. There remains no objective reference (i.e., ‘gold standard’) for the diagnosis.
Management
We are unaware of validated management algorithms using the Rome Criteria.
Critical Actions
IBS is a ‘rule-out’ diagnosis, which is to say all other possibilities must be ruled out first.
Advice
The Rome Criteria are helpful in classifying patients and for determining potential therapies.
