How this service works
Brindle 2021 Edinburgh gastric ulcer score (human gastric ulcer at index OGD): age <68 → 0, 68-79 → 1, ≥80 → 2; size <1.25 cm → 0, 1.25-2.99 cm → 2, ≥3.00 cm → 3 (no 1-point size band); antral 0, non-antral 1. Total 0-6. higher_malignancy_risk iff score ≥ 3. Use only with macroscopically benign appearance and ≥6 negative biopsies. magent does not read endoscopy images. Not equine EGUS. Not a medical device.
Output
Returns the Brindle 2021 Edinburgh gastric ulcer total score (integer 0–6), a boolean higher_malignancy_risk field (true if score ≥ 3), and the component subscores for age, ulcer size, and ulcer location.
Example use cases
Post-OGD malignancy risk stratification
“I have a 72-year-old patient with a macroscopically benign-looking gastric ulcer, 1.5 cm, in the non-antral region and 6 negative biopsies. Can you calculate the Brindle Edinburgh score and tell me if they're at higher malignancy risk?”
Elderly patient large antral ulcer
“My patient is 83 years old with a 3.2 cm antral gastric ulcer found at their index endoscopy — what does the Edinburgh gastric ulcer score come out to, and does it flag higher malignancy risk?”
Low-risk young patient scoring
“A 55-year-old presented with a 0.9 cm antral gastric ulcer at first OGD. Can you run the Brindle 2021 Edinburgh score to see if they're in the lower-risk group?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/egusWhen to prefer
Use this endpoint when you need a standardized, evidence-based gastric ulcer malignancy risk score for a human patient at index OGD with a macroscopically benign appearance and at least 6 negative biopsies. It implements the Brindle 2021 Edinburgh scoring rule exactly, making it preferable to manual calculation. Do not use for equine gastric ulcer syndrome (EGUS), for gastric ulcers with suspicious macroscopic appearance, or as a substitute for histopathology.
Side effects
- Missing required query parameters (age, ulcer_size_cm, location) returns a 400 error
- Age outside 18–120 range is clamped or rejected
- ulcer_size_cm outside 0.1–40 cm is clamped to internal bounds
- Invalid location enum value (not 'antral' or 'non-antral') returns validation error
- Payment not provided or insufficient USDC results in 402 Payment Required
