Table 1.
Ulcerative Colitis Colonoscopic Index of Severity.
| Score | Definition |
|---|---|
| Vascular pattern | |
| 0 | Normal, clear vascular pattern |
| 1 | Partially visible vascular pattern |
| 2 | Complete loss of vascular pattern |
| Granularity | |
| 0 | Normal, smooth, and glistening |
| 1 | Fine |
| 2 | Coarse |
| Ulceration | |
| 0 | Normal, no erosion or ulcer |
| 1 | Erosions or pinpoint ulcerations |
| 2 | Numerous shallow ulcers with mucopus |
| 3 | Deep, excavated ulcerations |
| 4 | Diffusely ulcerated with >30% involvement |
| Bleeding/friability | |
| 0 | Normal, no bleeding, no friability |
| 1 | Friable, bleeding to light touch |
| 2 | Spontaneous bleeding |
| Grading of SAES and GAES | |
| 0 | Normal/quiescent: visible vascular pattern with no bleeding, erosions, ulcers or friability (includes altered vascular pattern in quiescent disease) |
| 1 | Mild: erythema, decreased or loss of vascular pattern, fine granularity, but no friability or spontaneous bleeding |
| 2 | Moderate: friability with bleeding to light touch, coarse granularity, erosions or pinpoint ulcerations |
| 3 | Severe: spontaneous bleeding or gross ulcers |
The GAES also includes a 10-cm visual analog scale of severity.
GAES = global assessment of endoscopic severity; SAES = segmental assessment of endoscopic activity.
