Effects of modified Milligan-Morgan hemorrhoidectomy with acupuncture on postoperative wound healing and pain in mixed hemorrhoids

Table 3 Comparison of postoperative wound edema scores between the two groups (scores), mean ± SD

Indicators	Time point	Control group (n = 40)	Combined group (n= 40)	t/χ2	P value
Wound edema score	Day 1	2.43 ± 0.46	2.37 ± 0.26	0.668	0.506
	Day 3	1.74 ± 0.19	1.59 ± 0.12	4.130	< 0.001
	Day 7	0.91 ± 0.12	0.47 ± 0.07	19.800	< 0.001
Wound exudate score	Day 1	2.02 ± 0.27	2.11 ± 0.27	-1.462	0.148
	Day 3	1.80 ± 0.14	1.28 ± 0.11	18.685	< 0.001
	Day 7	0.56 ± 0.08	0.38 ± 0.05	12.319	< 0.001
Poor granulation tissue score	Day 1	1.82 ± 0.19	1.76 ± 0.19	1.346	0.182
	Day 3	1.27 ± 0.13	1.04 ± 0.12	8.098	< 0.001
	Day 7	0.74 ± 0.07	0.53 ± 0.06	14.599	< 0.001

This table compares postoperative wound edema scores, exudate scores, and poor granulation tissue scores at different time points between the two groups using independent samples t-test. No significant differences are observed on postoperative day 1 (P > 0.05), while the combined group shows significantly lower scores on postoperative days 3 and days 7 (P < 0.001).
