Splenectomy with endoscopic variceal ligation is superior to splenectomy with pericardial devascularization in treatment of portal hypertension

Table 3 Alteration of gastric emptying time after operation (mean ± SD)

Time points	Gastric emptying time (min)
	Group A (n = 53)	Group B (n = 50)
Before operation	55 ± 10	54 ± 8
3 wk after operation	53 ± 8	64 ± 7
6 wk after operation	51 ± 9	62 ± 6
12 wk after operation	54 ± 8	58 ± 8

There was no significant difference in the gastric emptying time between the two groups at each time point, or among the four time points in each group.
