x402
Callery 2013 Fistula Risk Score Calculator (Pancreatoduodenectomy) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Computes the Callery 2013 Fistula Risk Score after pancreatoduodenectomy from four caller-supplied clinical factors: gland texture, pathology type, pancreatic duct diameter, and estimated blood loss.

How this service works
Callery 2013 Fistula Risk Score after pancreatoduodenectomy: gland texture firm 0 / soft 2; pathology PDAC or pancreatitis 0 / other (ampullary, duodenal, cystic, islet cell) 1; duct mm ≥5 0, ≥4 1, ≥3 2, ≥2 3, else 4; EBL mL ≤400 0, 401–700 1, 701–1000 2, >1000 3. Max 10. Bands negligible 0, low 1–2, intermediate 3–6, high 7–10. magent does not palpate the gland or measure EBL. Not a CR-POPF diagnosis, not an ISGPS grade, not Ranson or BISAP. Not a medical device.
Output
Returns a numeric Fistula Risk Score from 0 to 10 and a corresponding risk band label (negligible, low, intermediate, or high), computed from the four Callery 2013 criteria: gland texture, pathology, duct diameter, and estimated blood loss.
Example use cases
Post-Whipple fistula risk stratification
“I need the Fistula Risk Score for a patient after pancreatoduodenectomy: the gland texture is soft, pathology is PDAC, duct diameter is 4.5mm, and estimated blood loss was 380mL — what band does that fall into?”
High-risk case identification pre-discharge
“Can you run the Callery fistula risk score for a patient with a soft pancreas, duodenal adenoma pathology (other), 2mm duct, and 800mL blood loss? I want to know if they're in the high-risk band.”
Comparing risk across two surgical cases
“Score the fistula risk for two cases: first, firm gland, PDAC pathology, duct 5mm, EBL 300mL; second, soft gland, cystic pathology, duct 2mm, EBL 1100mL — and tell me the risk band for each.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/fistula_riskWhen to prefer
Use this endpoint when you need a validated, reproducible implementation of the Callery 2013 Fistula Risk Score for post-pancreatoduodenectomy patients — particularly when integrating the score into surgical decision-support workflows or clinical documentation. Prefer this over manual calculation to avoid arithmetic errors in the scoring table. Not appropriate for diagnosing CR-POPF, assigning ISGPS grades, or for pancreatitis severity scoring (use Ranson or BISAP endpoints instead).
Side effects
- Missing required query parameters (gland_texture, pathology, duct_mm, ebl_ml) return a validation error
- duct_mm outside the accepted range (0.5–20) may cause a scoring error
- Invalid enum values for gland_texture or pathology return a 400-level error
- Payment failure (x402 protocol) prevents the call from completing
- Values at edge boundaries (e.g. duct_mm exactly 4.0) must be interpreted per Callery scoring table
