Abstract    Malignant biliary obstruction is a common complication of pancreatic cancer，carcinoma of the ampulla of Vater，and distal cholangiocarcinoma，often requiring biliary drainage to relieve symptoms. At present，ERCP with stent placement is the standard treatment for biliary drainage in patients with MBO. Moreover，common management techniques of palliative biliary drainage include surgical bypass，percutaneous transhepatic biliary drainage（PTBD） and EUS-guided biliary drainage（EUS-BD）. EUS-BD does not damage the papillary muscle and not require via the biliary stricture，which emerges the recent years and is increasingly used for distal malignant biliary obstruction. Therefore，the safety and efficacy of EUS-BD is an important issue that deserve further research attention.
