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

PHGgrading	Group A (n = 53)		Group B (n = 50)a
	Pre-operation	Post-operation	Pre-operation	Post-operation
Normal	3 (5.66)	2 (37.74)	5 (10.00)	2 (4.00)
Mild	25 (47.17)	23 (43.40)	27 (54.00)	8 (16.00)
Moderate	17 (32.08)	17 (32.08)	13 (26.00)	14 (28.00)

^aP < 0.05 vs post-operation;

^cP < 0.05 vs post-operation in group A.

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.
