The purpose

Endoscopic retrograde biliary drainage (ERBD) is now widely accepted as the standard intervention for the relief of obstructive jaundice in patients with unresectable malignant biliary obstruction. Although plastic stents (PSs) were developed earlier, self-expandable metal stents (SEMSs) are now used widely as the initial choice for ERBD in this setting, as SEMSs offer longer patency.However, SEMSs do become occluded in some patients. There are a limited number of reports on the management of occluded SEMS with various results. The aim of this study is to compare the efficacy of ComVi stents SEMSs with uncovered SEMS in subsequent ERBD after the occlusion of initial SEMSs.
