Impact of Intra-Abdominal Adhesion on Dialysis Outcome in Peritoneal Dialysis Patients

Table 3

Comparison between subsequent intra-abdominal adhesion and prior surgical procedures.

	Surgery(n=40)		Non-surgery (n=162)		p-value
	With adhesion	Without adhesion	With adhesion	Without adhesion
Patients numbers (n)^d	16 (40 %)	24 (60 %)	22 (13.6 %)	140 (86.4 %)	<0.001
Age (years)	60.7±12.8	50.5±12.7	51.6±16.4	49.1±14.2	0.023
Operation time (minutes)	81.4±43.4	71.3±34.2	76.7±24.5	72.4±30.2	0.670
PD peritonitis [n (%)]^d	8 (21.1%)	8 (4.9%)	11 (28.9%)	47 (28.7%)	0.161

a = previous abdominal surgery.
b and c = the age and operation time among four groups were compared by means of one-way ANOVA.
d =the differences among four groups were compared by means of a Chi-Square test.
