摘要

Background Although self-expandable metallic stent (SEMS) has a longer patency than plastic stent (PS) for malignant biliary obstruction, stent occlusion can occur and drainage has to be reestablished in a patient with expected long survival. However, the choices are still controversial among restenting with SEMS, PS, and percutaneous transhepatic biliary drainage (PTBD). This study was designed to determine the efficacy and outcome of PS, SEMS, and PTBD for patients with occluded SEMS.
