Advantages and Disadvantages of EUS-BD

	EUS-BD	EBD	PTBD
Advantage	A single step internal drainage	Long term data available	High technical success rate
	Simplicity at the hilum: possible longer patency		Possible tube rinse for clogging
Disadvantage	No long term data	Technical difficulty for multiple stenting	Impaired QOL
	Special technique necessary for right IHBD approach	Complexity at the hilum	High AE rate and re-intervention rate
	Contraindications: ascites, coagulopathy	Chance of Post-ERCP pancreatitis	Contraindications: ascites, coagulopathy
	Chance of bile leak, stent migration

AE, adverse event; EBD, endoscopic transpapillary biliary drainage; ERCP, endoscopic retrograde cholangiopancreatography; EUS-BD, endoscopic ultrasound-guided biliary drainage; IHBD, intrahepatic bile duct; PTBD, percutaneous transhepatic biliary drainage; QOL, quality of life.
