Comparison of the Characteristics of Each Stent for Endoscopic Ultrasound (EUS)-Guided Bile Duct Drainage

Type of stent Possible type Advantage Disadvantage
Plastic stent - Single-pigtail stent
- Double-pigtail stent
- Less expensive
- Convenience for revision
- Less shortening of stent
- Less tumor tissue hyperplasia or ingrowth/overgrowth
- Frequent stent dysfunction including occlusion due to the small diameter of the stent
- Possible bile leakage along the stent
Fully or partially covered self-expandable metal stent (FCSEMS or PCSEMS) - PCSEMS or FCSEMS without anti-migrating flanges
- PCSEMS or FCSEMS with anti-migrating flanges (unidirectional or bidirectional)
- Longer stent patency than plastic stent due to larger diameter of the stent
- Theoretically less bile leakage
- Relatively expensive
- Side-branch obstruction leading to biloma or hepatic abscess
- Stent malposition
- Higher rate of stent shortening leading to stent migration
Lumen-apposing metal stent (LAMS) - Only for EUS-guided choledochoduodenostomy
- LAMS with bidirectional anchoring flanges but no electrocautery-enhanced tip
- LAMS with electrocautery-enhanced tip
- Largest diameter
- Longer stent patency
- Shorter procedure time due to one-step creation of the fistula
- Omitting unnecessary steps, including balloon dilation
- Migration is rare
- Very expensive
- Rare but possible adverse events of significant bleeding or buried LAMS syndrome
