Rutgeerts Score (post-op Crohn’s recurrence)
Rutgeerts score (Rutgeerts 1990): endoscopic grade of post-operative Crohn’s recurrence in the neoterminal ileum (i0–i4); ≥ i2 predicts clinical recurrence.

Example
- Neoterminal-ileum endoscopic finding
- i2 — > 5 aphthous lesions (normal mucosa between), skip areas, or…
Result: Rutgeerts i2 — predicts clinical recurrence (≥ i2).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Grades
- i0 no lesions; i1 ≤5 aphthous lesions; i2 >5 aphthous lesions / skip areas / anastomosis-confined; i3 diffuse aphthous ileitis; i4 diffuse inflammation with large ulcers/nodules/stenosis.
- Prognosis
- A grade ≥ i2 predicts clinical recurrence; i0–i1 is low risk.
What you enter
