Comparison of preoperative food and liquid fasting times, preoperative blood glucose level, postoperative complications, and degree of satisfaction between the two groups

	Conventional group (n = 151)	ERAS group (n = 152)	P value
Preoperative liquid fasting time (h), median (range)	12.00 (3.00, 20.28)	3.00 (2.00, 7.50)	< 0.001
Preoperative food fasting time (h), median (range)	13.00 (6.00, 20.28)	11.92 (4.00, 19.33)	< 0.001
Preoperative blood glucose (mmol/L), median (range)	5.1 (4.0, 7.4)	5.6 (4.2, 8.2)	< 0.001
Time to postoperative feeding (h), median (range)	6.00 (5.40, 9.20)	1.17 (0.33, 6.83)	< 0.001
Postoperative vomiting, n (%)	4 (2.6)	3 (2.0)	0.993
Postoperative fever, n (%)	7 (4.6)	6 (3.9)	0.767
Satisfaction (points)	7 (0, 10)	8 (5, 10)	< 0.001

ERAS: Enhanced recovery after surgery; SD: Standard deviation.
