To report a case of recurrent biliary obstruction due to food impaction within a lumen-apposing metal stent (LAMS) after endoscopic ultrasound-guided biliary drainage (EUS-BD) in a patient with unresectable pancreatic cancer, highlighting its significance in clinical practice.
Key Findings:
The patient experienced recurrent obstructive jaundice due to food impaction within the LAMS, a rare complication.
No tumor ingrowth, overgrowth, or sludge accumulation was observed, indicating that the obstruction was solely due to food debris.
Endoscopic removal of food debris and placement of a coaxial stent restored luminal patency, demonstrating an effective management strategy.
Interpretation:
Food impaction is an unusual but significant cause of recurrent obstructive jaundice following EUS-BD with LAMS, warranting further attention in clinical practice.
Limitations:
The case is a single patient report, limiting generalizability to broader populations.
Long-term dietary habits and their impact on LAMS function were not systematically studied, which could inform future guidelines.
Conclusion:
This case emphasizes the need for dietary counseling in patients with indwelling LAMS to prevent food impaction and recurrent biliary obstruction, highlighting the importance of monitoring dietary habits post-procedure.
