COVERED METALLIC STENT FOR ISCHEMIC HILAR BILIARY STRICTURE

Compared with surgery, endoscopic treatment is safe and highly effective for a postoperative hilar benign bile duct stricture (BDS). However, the long‐term outcome of conventional placement of a single biliary stent for hilar benign BDS is generally poor. Although the placement of multiple biliary stents is preferred, multiple stenting in a BDS is difficult. Alternatively, single or multiple stent placement above the papilla (‘inside stent’) or fully‐covered self‐expandable metallic stents (SEMS) are feasible approaches for benign BDS. Nevertheless, controversy remains regarding whether and how to perform endoscopic biliary drainage for a hilar benign BDS. In patients with hilar benign BDS, endoscopic biliary drainage can be performed by placing conventional plastic stents across the papilla, plastic stents above the papilla or fully‐covered SEMS. Individualized treatment should be considered. We report the placement of a fully‐covered SEMS for a hilar benign biliary stricture after extended left hepatectomy.
