Combined side‐by‐side and stent‐in‐stent method for triple metal stenting in patients with malignant hilar biliary obstruction

Endoscopic placement of three branched self‐expandable metallic stents (SEMS) for high‐grade malignant hilar biliary obstruction (MHBO) is technically challenging. We examined the feasibility and efficacy of a novel stenting method combining side‐by‐side and stent‐in‐stent (SBSIS) placement for MHBO.
