Table I. Parameters for semiquantitative assessment of anastomotic healing.

The absolute score focuses only on the level of integrity of a selected intestinal wall layer, while the weighted score corrects this result to make each layer have the same impact in the total score. *Samples without nanomaterial were scored: score 2 for no necrosis, score 1 (2/12) for purulent infiltration and/or necrosis from muscular layer to ½ thickness of serosa and score 0 (1/12) for purulent infiltration and/or necrosis reaching more than ½ thickness of serosa to peritoneum.
