| Core Tip |
We aimed to assess whether the angle of covered self-expandable metallic stents (CSEMS) after placement is a risk factor for recurrent biliary obstruction (RBO) in patients with unresectable distal malignant biliary obstruction. We included 87 patients in this study and divided them into 2 cohorts. We found that the angle of the CSEMS after placement was an independent risk factor for RBO. Furthermore, we demonstrated that the cut-off value of the angle of CSEMS after placement was 130° and that time to RBO in the < 130° group was significantly shorter than that in the ≥ 130° group. |
