    Pearls/Pitfalls
    Why Use

    Patients being evaluated for possible IBS.

    • The Manning Criteria were developed through patient survey and follow-up.
    • They differentiate patients with organic and non-IBS conditions.

    Points to keep in mind:

    • Studies have found highly variable diagnostic performance of the criteria.

    The symptoms that define IBS are subjective and self-reported, making a diagnostic classification system helpful. Moreover, there is evidence to support the notion that patients meeting criteria may be more likely to respond to some therapies.

    3+ required for positive diagnosis (and 0 red flags)

    Advice

    The Manning Criteria were developed to help predict which patients will de diagnosed with IBS, i.e. will not have any organic disease identified after complete work-up. In a setting where work-up resources are limited, or take undue time, these may be particularly useful.

    Management

    We are unaware of validated management algorithms using the Manning Criteria.

    Critical Actions

    IBS is a ‘rule-out’ diagnosis, which is to say all other possibilities must be ruled out first.
