| Rutgeerts Score [10] | |
| i0 | No lesions |
| i1 | ≤5 aphthous lesions in the neoterminal ileum |
| i2 | >5 aphthous lesions with normal intervening mucosa or skip area of large lesions or lesions confined to the ileo-colonic anastomosis |
| i3 | Diffuse aphthous ileitis with diffusely inflamed mucosa |
| i4 | Large ulcers with diffuse mucosal inflammation or nodules or stenosis in the neo-terminal ileum |
| Modified Rutgeerts Score [14] | |
| i0 | No lesions |
| i1 | ≤5 aphthous lesions in the neoterminal ileum |
| i2a | Lesions confined to the ileo-colonic anastomosis (including anastomotic stenosis) |
| i2b | >5 aphthous ulcers or large lesions, with normal mucosa in-between, in the neo-terminal ileum (with or without anastomotic lesions) |
| i3 | Diffuse aphthous ileitis with diffusely inflamed mucosa |
