Abstract

Patients with malignant biliary obstruction, following endoscopic retrograde cholangiopancreatography (ERCP) failure could be referred for endoscopic-ultrasound-guided biliary drainage through electrocautery-enhanced (ECE) lumen-apposing metal stent (LAMS) placement. However, the efficacy and safety of ECE-LAMS in this scenario have remained debatable due to minimal scientific evidence. The current confirmed 91.0% clinical success, 96.7% technical success, 7.3% reintervention rate, and 17.5% adverse events, following the treatment of malignant biliary obstruction with ECE-LAMS delivery. Finally, ECE-LAMS proved to be a generalizable strategy for managing biliary obstruction for patients who were excluded from ERCP.

Core Tip: The ultrasound-directed electrocautery-enhanced-lumen-apposing metal stent placement is a viable approach for malignant biliary obstruction treatment in patients who do not qualify for endoscopic retrograde cholangiopancreatography (ERCP) or in those with ERCP failure. This finding relies on the acceptable reintervention rate, greater clinical success, and manageable/low adverse events, obtained in the current study.
