Recent advancements in endoscopic ultrasound (EUS) technology and devices have led to the increased adoption of EUS-guided biliary drainage (EUS-BD) and EUS-guided fine-needle aspiration/biopsy (EUS-FNA/B) for biliary diseases. EUS-BD, in particular, is proving effective even in cases where ERCP is challenging, and is expected to become a standard treatment for biliary drainage alongside ERCP. This review introduces the classification and terminology of EUS-related procedures proposed by the Japan Gastroenterological Endoscopy Society, categorizing them into five distinct groups based on the latest findings. The focus then shifts to EUS-BD, highlighting key technical considerations and new devices to manage complications. The review also discusses the "Revised Tokyo Criteria 2024," which proposes standardized evaluation methods for endoscopic biliary drainage, with a particular emphasis on EUS-BD. By unifying terminology and evaluation criteria across studies, the review aims to facilitate data comparison and further advance EUS-related procedures in the treatment of biliary diseases. Standardization of procedure terminology and evaluation criteria will facilitate comparison of data across studies and should further advance EUS-related procedures in biliary disease.
