Can an ERCP stent be removed later?

Yes, an ERCP stent can often be removed later, but it depends on the type of stent and the underlying condition.

✅ Removable Stents

Plastic Stents

• Always removable

• Commonly used for benign conditions (e.g., bile duct stones, strictures, leaks)

• Typically removed or replaced after 3–4 months to prevent clogging

Covered Metal Stents (Covered SEMS)

• Designed to be removable

• Often used when temporary decompression is needed, or in benign strictures

• Easier to remove than uncovered metal stents, though care is needed during retrieval

Non-Removable Stents

Uncovered Metal Stents (Uncovered SEMS)

• Not intended for removal

• Used mostly for malignant obstructions

• Allow tissue ingrowth to anchor the stent, making removal dangerous or impossible

Stent Removal Process

• Performed via repeat ERCP

• Usually quick, done under sedation

• Involves grasping the stent with a snare or forceps and pulling it out through the endoscope
