Table 5 Comparison of serum index results before and after endoscopic sphincterotomy in biliary-type sphincter of Oddi dysfunction patients

Serum index1	Biliary-type SOD		P value
	Pre-EST	Post-EST
ALT [M (IQR), U/L]	70.00 (24.10-190.03)	29.22 (18.00-58.00)	< 0.001
AST [M (IQR), U/L]	61.51 (26.08-157.79)	30.59 (22.00-64.00)	< 0.001
TBIL [M (IQR), mg/dL]	2.98 (1.49-5.02)	2.00 (1.14-3.03)	0.004
ALP [M (IQR), U/L]	129.00 (91.50-220.91)	7.60 (3.70-12.30)	< 0.001

¹The serum index was 1 wk before and after endoscopic sphincterotomy.

SOD: Sphincter of Oddi dysfunction; EST: Endoscopic sphincterotomy; ALT: Alanine aminotransferase (Reference range: 5-40 U/L); AST: Aspartate aminotransferase (Reference range: 8-40 U/L); ALP: Alkaline phosphatase (Reference range: 40-110 U/L); TBIL: Total bilirubin (Reference range: 1.71-17.1 U/L).
