[New techniques to extract impacted partially covered metallic biliary stents]

Area of Science:

• Gastroenterology and Endoscopy
• Biliary Interventions

Background:

• Metallic biliary stents are used to treat biliary stenosis but can be difficult to remove, particularly after migration.
• Existing stent removal methods have variable effectiveness, posing a clinical challenge.

Observation:

• This study reports two novel approaches for removing proximally migrated, partially covered metallic biliary stents impacted in the papillary area and distal common bile duct.
• One stent was successfully removed via papillectomy.
• Another stent was removed using duodenoscopy-guided controlled radial expansion balloon dilation.

Findings:

• Both novel techniques achieved successful stent removal without severe complications.
• The procedures preserved a good caliber of the bile duct stenosis post-removal.

Implications:

• These methods offer effective solutions for challenging metallic biliary stent removal.
• The techniques may improve patient outcomes and reduce the need for more invasive procedures.
