Summary
Proximal migration of biliary stents is challenging but manageable. Most migrated stents can be successfully retrieved endoscopically using direct grasping or indirect traction techniques.
Area of Science:
- Gastroenterology
- Endoscopic retrograde cholangiopancreatography (ERCP)
Context:
- Proximal migration of biliary stents is an infrequent complication.
- Management of migrated biliary stents poses technical difficulties for endoscopists.
Purpose:
- To review methods for retrieving proximally migrated biliary stents.
- To evaluate the success rates of different endoscopic retrieval techniques.
Summary:
- A review of 410 biliary stent insertions identified 18 cases of migrated stents.
- Endoscopic retrieval was successful in 15 of 18 patients (83%).
- Techniques included direct wire basket grasping (50%), Soehendra device, and indirect balloon traction.
Impact:
- Direct grasping or indirect balloon traction are effective for migrated stents in dilated ducts.
- Wire cannulation of the stent lumen is useful for strictures or nondilated ducts.
- Most proximally migrated biliary stents can be retrieved endoscopically, avoiding surgery.
