Enterocolitis Score System for Histology Evaluation

	Intestinal-fold architecture disruption
Numerical score	Impaired epithelial integrity	Expanded clefts/reduced projections	Expanded gut lumen	Goblet cell appearance
0	Normal	Normal	Normal	Normal
1	Slight disruption	Slight disruption	Slight expansion	Increased in number
2	Moderate disruption	Moderate disruption	Moderate expansion	Increased in number and different in sizes
3	Severe disruption	Severe disruption	Severe expansion	Severe morphological changes
