Table 2. Evaluation of peritoneal adhesions in the rat model.

Adhesions	Control group		HA hydrogel group		PLEL hydrogel group
	(n = 8)		(n = 8)		(n = 8)
	Frequency	Percentage	Frequency	Percentage	Frequency	Percentage
Score 0	0	0	0	0	7	87.5
Score 1	0	0	1	12.5	0	0
Score 2	0	0	3	37.5	1	12.5
Score 3	8	100	4	50	0	0
Median score	3(3–3)		3(3–3)		0(0–2)*

Score 0 = no adhesion; score 1 = mild adhesion; score 2 = moderate intestinal adhesion;

score 3 = severe intestinal adhesion.

*Significantly different with the values of control group, P ≤ 0.05, Mann-Whitney μ tests.
