Comparison of liver function between the two groups
Before surgery, there was no statistically significant difference between the levels of AST, TBiL, ALT and ALB in the two groups (P > 0.05); 1 week after surgery, the levels of AST, TBiL, ALT and ALB decreased in both groups, with the levels of AST, TBiL, ALT and ALB in the study group markedly higher than those in the control group(P < 0.05), as shown in Table
