Quality of Life and Clinical Outcomes of Endosonography-Guided Biliary Drainage in Patients with Malignant Biliary Obstruction: A Single-Center, Prospective Analysis.

Endosonography-guided biliary drainage (EUS-BD) serves as a rescue treatment modality for patients with malignant biliary obstruction when endoscopic retrograde cholangiopancreatography (ERCP) fails. This study explores the effects of EUS-BD on liver function and quality of life (QoL). Patients with malignant biliary obstruction and failed ERCP were enrolled to undergo EUS-BD.
