Table 2 Scale used for histological evaluation of the anastomotic healing: value from 1 to 4 for the inflammation and 1 to 3 for vascularization and collagen content
Score | Inflammation: number of giant cells—(GC) and lymphocytes (L) | Collagen deposition (layers) | Blood vessels in mucosa at anastomosis |
|---|---|---|---|
1 | GC, L < 5 | Thickness 1–3 layers | < 5 |
2 | GC, L 5–10 | Thickness 4–10 layers | 6–10 |
3 | GC, L 11–15 | Thickness > 10 layers | > 10 |
4 | GC, L > 15 | – | – |
