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

Table 5 Comparison of postoperative complication rates between the two groups, n (%)

Characteristics	Anal stenosis	Anal discharge	Urinary retention	Wound infection	Perianal edema	Overall incidence
Control group (n = 40)	1 (2.50)	2 (5.00)	3 (7.50)	2 (5.00)	3 (7.50)	11 (27.50)
Combined group (n= 40)	0 (0.00)	1 (2.50)	1 (2.50)	1 (2.50)	1 (2.50)	4 (10.00)
t	1.013	0.346	1.053	0.346	1.053	4.021
P value	0.314	0.556	0.305	0.556	0.305	0.045

This table compares postoperative complication rates between the two groups using χ² test. The overall incidence of complications in the combined group is significantly lower than that in the control group (P < 0.05), while no significant differences are found in individual complication types (P > 0.05).
