Core Tip
Core tip: To date, many case reports, series, and retrospective studies on EUS-guided biliary drainage (EUS-BD) have been reported. However, because prospective studies and comparisons between the different biliary drainage methods have not been reported, the technical success, functional success, adverse events, and stent patency with long-term follow up of EUS-BD are still unclear. Therefore, prospective, randomized controlled studies addressing these issues are needed. Despite this, EUS-BD undoubtedly is clinically useful. EUS-BD has the potential to be a first-line biliary drainage method instead of endoscopic retrograde cholangiopancreatography if results of clinical trials are favorable and the technique is simplified.
