How this service works
Stanghellini 2016 Rome IV rumination syndrome. rome_iv_rumination is true iff persistent or recurrent regurgitation of recently ingested food with subsequent spitting or remastication and swallowing, regurgitation not preceded by retching, last-3-months criteria, and 6-month onset. Supportive remarks (effortless, not preceded by nausea, recognizable food, ceases when acidic) are copy-only and not parsed. magent does not observe regurgitation. Not a diagnosis, not CHS, not CVS, not GERD.
Output
Returns a boolean field rome_iv_rumination indicating true if all four Rome IV rumination syndrome criteria (Stanghellini 2016) are simultaneously met: persistent or recurrent regurgitation of recently ingested food, regurgitation not preceded by retching, criteria fulfilled for the last 3 months, and symptom onset at least 6 months prior. Returns false otherwise. Does not diagnose, does not take history, does not distinguish from CHS, CVS, or GERD.
Example use cases
Gastroenterology clinic Rome IV screening
“I'm seeing a patient with recurrent regurgitation of recently ingested food, no retching before episodes, criteria met for the last 3 months, and symptoms started more than 6 months ago — does this meet Rome IV rumination syndrome?”
Ruling out rumination in functional GI workup
“Patient has regurgitation but it is preceded by retching. Symptoms have lasted 3 months with onset 6 months ago. Does this patient still qualify under Rome IV rumination syndrome criteria, or does the retching disqualify them?”
Teaching case criteria verification
“For this GI board review case: persistent regurgitation of recently ingested food, not preceded by retching, criteria fulfilled last 3 months, onset 7 months ago — is Rome IV rumination syndrome criteria satisfied, true or false?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rome_iv_ruminationWhen to prefer
Use this endpoint when you need a deterministic, structured evaluation of the Rome IV (Stanghellini 2016) rumination syndrome criteria and you have already collected and assigned all four required boolean clinical findings. Prefer this over manual lookup when building a clinical decision support workflow or automating functional GI disorder screening. Do not use if you need diagnosis, history-taking, or differentiation from CHS, CVS, or GERD.
Side effects
- Missing required query parameters returns a validation error
- Passing non-boolean values for boolean fields may cause a parsing error
- Endpoint does not validate clinical plausibility — all four booleans must be explicitly assigned by the caller
- Cannot handle ambiguous or null clinical findings — caller must resolve uncertainty before querying
