Unveiling the potential of electrocautery-enhanced lumen-apposing metal stents in endoscopic ultrasound-guided biliary drainage

Core Tip

Core Tip: This meta-analysis highlights the effectiveness of electrocautery-enhanced lumen-apposing metal stents (ECE-LAMS) in ultrasound-guided biliary drainage for malignant obstruction. Based on diverse studies, it demonstrates a strong technical success rate of 96.7%, showcasing ECE-LAMS' efficacy in challenging cases post-failed endoscopic retrograde cholangio pancreatography. The notably high clinical success rate underscores its impact on symptom relief, and the safety profile is deemed acceptable. However, the observed adverse events and re-intervention rate emphasize the importance of vigilant post-procedural monitoring. Consistent outcomes across subgroups enhance the applicability of ECE-LAMS, positioning it as a versatile tool for palliation in cases of malignant biliary obstruction.
