How this service works
Rao 2016 Rome IV proctalgia fugax (F2c). rome_iv_proctalgia_fugax is true iff recurrent rectal pain unrelated to defecation, episodes seconds to minutes (max 30 min), no anorectal pain between episodes, other causes excluded, last-3-months criteria, and 6-month onset. magent does not examine the rectum. Not a diagnosis, not levator ani, not unspecified functional anorectal pain.
Output
Returns a boolean field (rome_iv_proctalgia_fugax) indicating whether all six Rome IV F2c criteria for proctalgia fugax are satisfied based on the caller-supplied inputs. No physical examination or history-taking is performed by the service.
Example use cases
Ruling in proctalgia fugax in clinic
“My patient has brief rectal pain spasms unrelated to defecation, episodes last under a minute, no pain between episodes, IBD and fissures have been ruled out, this has been going on for over 6 months and meets the last-3-month window — does this satisfy Rome IV proctalgia fugax criteria?”
Differentiating from levator ani syndrome
“A patient reports rectal pain that comes and goes in very short bursts — under 30 minutes each — with nothing in between. Other causes excluded, pattern established over 6 months and active in the last 3 months. Can you confirm this fits proctalgia fugax and not levator ani syndrome by Rome IV?”
Automated chart review for functional GI coding
“For this patient's chart: recurrent rectal pain unrelated to defecation is yes, episodes are seconds to minutes, no inter-episode pain, other causes excluded, fulfilled last 3 months, onset over 6 months ago — run the Rome IV proctalgia fugax check and tell me if criteria are met.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rome_iv_proctalgia_fugaxWhen to prefer
Use this endpoint when you need a fast, structured Rome IV F2c proctalgia fugax determination and have already gathered the six required clinical criteria from a clinician or structured record. Prefer this over manual lookup when building clinical decision support workflows, automated chart coding, or gastroenterology triage tools. Not appropriate for diagnosing levator ani syndrome (episodes ≥30 min) or unspecified functional anorectal pain.
Side effects
- Missing any of the six required boolean query parameters returns an error
- Passing non-boolean values for boolean fields causes a validation error
- Misclassifying episode duration (e.g. episodes >30 min) will return false, distinguishing from levator ani syndrome
- Service does not validate clinical accuracy of caller-assigned inputs — garbage in, garbage out
