How this service works
Rao 2016 Rome IV levator ani syndrome. rome_iv_levator_ani is true iff chronic or recurrent rectal pain or aching, episodes lasting 30 minutes or longer, tenderness during puborectalis traction (caller assigns; magent does not perform traction), other causes of rectal pain excluded, last-3-months criteria, and 6-month onset. Not a diagnosis, not proctalgia fugax, not unspecified functional anorectal pain (F2b).
Output
Returns a boolean field rome_iv_levator_ani indicating true if all six Rome IV F2a criteria are simultaneously met (chronic/recurrent rectal pain or aching, episodes ≥30 min, puborectalis tenderness, other causes excluded, criteria fulfilled for last 3 months, onset ≥6 months prior), and false otherwise. This is a computational criterion check, not a medical diagnosis.
Example use cases
Gastroenterology clinic functional anorectal triage
“I just finished examining a patient with recurrent rectal aching — episodes last about 45 minutes, I found tenderness on puborectalis traction, I've ruled out IBD, fissure, hemorrhoids, and abscess, and they've had symptoms for over 6 months with the full picture present for the last 3 months. Do they qualify for Rome IV levator ani syndrome?”
EHR-integrated Rome IV auto-classification
“The chart shows: chronic rectal pain present, episodes longer than 30 minutes, puborectalis tenderness confirmed, other structural and inflammatory causes excluded, criteria satisfied for the past 3 months, onset more than 6 months ago. Run the Rome IV levator ani syndrome check and tell me if they meet F2a.”
Differentiating levator ani syndrome from proctalgia fugax
“My patient has chronic rectal pain lasting 30 minutes or more per episode with puborectalis tenderness, other causes ruled out, 3-month criteria met, and onset 8 months ago — does this meet Rome IV levator ani syndrome rather than proctalgia fugax or unspecified functional anorectal pain?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rome_iv_levator_aniWhen to prefer
Use this endpoint when you need a fast, structured, reproducible Rome IV F2a levator ani syndrome criterion check based on already-gathered clinical findings. Prefer it over manual lookup when building clinical decision support tools, EHR integrations, or gastroenterology triage agents that need to distinguish levator ani syndrome from proctalgia fugax (F2b) or unspecified functional anorectal pain. All six criterion values must be pre-assessed by a qualified clinician before calling.
Side effects
- Missing any required query parameter returns an error — all six boolean fields are mandatory
- Passing non-boolean values for any criterion will cause a validation error
- Network or payment failure (x402 payment required) if USDC payment is not included
- If caller incorrectly assigns clinical findings (e.g. tenderness not actually checked), the result reflects erroneous inputs — garbage in, garbage out
