摘　　要：In this editorial,we comment on the article by Peng et al.Palliative drainage for biliary obstruction resulting from unresectable malignant lesions includes internal and external drainage.The procedures of biliary drainage are usually guided by fluoroscopy or transcutaneous ultrasound,endoscopic ultrasound(EUS),or both.Endoscopic retrograde cholangiopancreatography(ERCP)has been primarily recommended for the management of biliary obstruction,while EUS-guided biliary drainage and percutaneous transhepatic biliary drainage(PTBD)are alternative choices for cases where ERCP has failed or is impossible.PTBD is limited by shortcomings of a higher rate of adverse events,more reinterventions,and severe complications.EUS-guided biliary drainage has a lower rate of adverse events than PTBD.EUS-guided biliary drainage with electrocautery-enhanced lumen-apposing metal stent(ECE-LAMS)enables EUS-guided biliaryenteric anastomosis to be performed in a single step and does not require prior bile duct puncture or a guidewire.The present meta-analysis showed that ECELAMS has a high efficacy and safety in relieving biliary obstruction in general,although the results of LAMS depending on the site of biliary obstruction.This study has highlighted the latest advances with a larger sample-based comprehensive analysis.
