Abstract Background Malignant biliary obstruction secondary to metastatic cancer is associated with poor prognosis. To the best of our knowledge, no previous study has investigated long-term survival and associated prognostic factors after biliary endoscopic retrograde cholangiopancreatography (ERCP) drainage for obstruction jaundice secondary to various types of metastatic cancer. Methods This retrospective study included 60 patients who underwent biliary ERCP drainage for obstructive jaundice secondary to metastatic cancer at two hospitals during the period from November 2012 to December 2019. Multivariate analysis was conducted to identify independent prognostic factors. Results Biliary drainage was successfully achieved in 55 (91.7%) patients, 37 of whom received subsequent treatment. Overall median survival time was 133 days after stent placement. The overall survival (OS) rates after ERCP drainage were significantly better in the post-drainage treatment group than in the post-drainage untreated group (239 days vs. 45 days, p
