Shin Miura et al. Risk factors for recurrent biliary obstruction following placement of self-expandable metallic stents in patients with malignant perihilar biliary stricture

In this retrospective cohort study it is shown that the risk for recurrent obstruction after placement of a self-expandable metal stent (SEMS) in patients with perihilar biliary strictures is associated with cholangitis before SEMS insertion, left-sided drainage compared with bilateral drainage, and perihilar stricture due to gallbladder cancer.
