Table 2 Incidence rate of intraperitoneal effusion, n (%)/mean ± SD

Time point	Number of positive effusion (%)	Maximum effusion depth (mm)	χ²/t	P value
POD1	28 (35.00)	12.56 ± 3.24	-	-
POD3	42 (52.50)	15.48 ± 4.17	5.12	0.024
POD7	37 (46.25)	13.92 ± 3.85	1.21	0.271

P < 0.05 indicated significant difference. The incidence peaked on postoperative day 3 (52.50%). P values are derived from generalized estimating equation models comparing each time point to postoperative day 1. POD: Postoperative day.
