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

From: Comparison of two different barbed suture materials for end-to-end jejuno-jejunal anastomosis in pigs

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
