Short-Term Biliary Stent Placement Contributing Common Bile Duct Stone Disappearance with Preservation of Duodenal Papilla Function

Procedures during the second ERCP and cholangitis after the second ERCP.

	Procedures during the second ERCP	(%)	Cholangitis
			(%)
Stone disappearance	Biliary stent removal	32 (48.5)	1 (3.1)^#
Stone persistence	Stone extraction with EST	17 (25.8)	2 (11.8)^#
	Stone extraction by a basket catheter without EST	10 (15.1)	1 ()^#
	Biliary stent replacement for persistent biliary stent placement	7 (10.6)	3 (42.9)
