Rapid biliary stent clogging: two case reports in a 12 year ERCP series

Area of Science:

• Gastroenterology
• Hepatology
• Interventional Endoscopy

Background:

• Biliary stent placement is a common procedure for managing biliary obstruction.
• Stent dysfunction, including clogging, can lead to treatment failure and complications.
• Rapid stent clogging is an underreported phenomenon in clinical literature.

Observation:

• Two distinct cases of rapid biliary stent clogging were identified within a 12-year series of endoscopic retrograde cholangiopancreatography (ERCP) procedures.
• The cases involved patients experiencing acute stent failure due to rapid occlusion.
• Detailed clinical and procedural data were collected for analysis.

Findings:

• The presented cases represent rare instances of rapid biliary stent occlusion.
• Analysis revealed specific challenges in diagnosing and managing such rapid clogging events.
• The frequency and causative factors of rapid clogging remain poorly understood.

Implications:

• Highlights the need for increased awareness and documentation of rapid biliary stent clogging.
• Suggests potential areas for further research into the mechanisms and prevention of stent occlusion.
• Emphasizes the importance of timely diagnosis and intervention for patients experiencing stent dysfunction.
