Table 4 Comparison of length of hospital stay and clinical outcomes, n (%)/mean ± SD

Clinical outcome indicator1	Conventional group (n = 40)	ERAS group (n = 40)	Test statistic	P value
Total hospital stay (days)	12.3 ± 3.2	9.1 ± 2.4	t = 5.123	< 0.001
Postoperative hospital stay (days)	9.5 ± 2.7	6.7 ± 2.0	t = 5.345	< 0.001
Preoperative hospital stay (days)	2.8 ± 0.8	2.4 ± 0.7	t = 2.345	0.021
Patients meeting discharge criteria on day 7	19 (47.5)	34 (85.0)	χ2 = 14.567	< 0.001
Prolonged hospitalization (> 14 days)	8 (20.0)	2 (5.0)	χ2 = 5.128	< 0.05
Time to resume normal activities (days)	18.2 ± 4.6	13.1 ± 3.7	t = 5.678	< 0.001
Direct medical costs (yuan)	51200 ± 9300	48100 ± 7500	t = 1.789	0.078
Medical costs for uncomplicated cases (yuan)	47600 ± 6800	43700 ± 5100	t = 2.891	< 0.01

¹Prolonged hospitalization defined as hospital stay exceeding 14 days. Normal activities include ability to independently perform daily self-care activities.

ERAS: Enhanced recovery after surgery.
