Changes in liver function in patients who underwent laparoscopic surgery

Age at surgery	≤ 2 Months (n = 23)			> 2 Months (n = 21)
Liver function	At surgery	1 week after surgery	P	At surgery	1 week after surgery	P
ALT(U/L, M[P25,P75])	19.0[13.0,27.0]	29.0[15.0,43.0]	0.014	45.0[34.0,97.5]	31.0[23.5,66.0]	0.035
AST(U/L, M[P25,P75])	32.0[23.0,41.0]	32.0[21.0,45.0]	0.484	55.0[37.0,102.0]	32.0[27.0,62.0]	0.007
γ-GT(U/L, M[P25,P75])	229.0[105.0,542.0]	222.0[120.0,339.0]	0.465	49.0[28.5,300.0]	98.0[49.5,224.5]	0.566
DBIL(umol/L, M[P25,P75])	13.40[7.55,25.92]	6.30[4.80,13.53]	0.001	4.31[2.17,8.12]	2.81[2.40,4.37]	0.013
Cholestasis before surgery(Yes/No, n)	7/16	4/19	0.300	3/18	2/19	1.000

The Wilcoxon test was used to evaluate the ALT, AST, γ-GT, and DBIL levels between the time of surgery and 1 week after surgery at various ages
