Postoperative complications

	VAC group (n=31)	Non VAC group (n=34)	P-value
Surgical site infection (SSI)	1/31	9/34	0.014
Complication after operation except SSI	2/31	2/34	1.000
Length of hospital stay (days)	11.0 (8.0–30.0)	12.0 (7.0–41.0)	0.544

There was no significant difference in postoperative complications other than SSI between the two groups. Notably, the incidence of SSI was significantly lower in the VAC group than in the non-VAC group. There was no significant difference in the length of hospital stay between the two groups (11 vs. 12 days).
