In patients with benign biliary strictures, the use of fully covered self-expandable metal stents (SEMS) has been proposed as an alternative to plastic stenting, but high quality prospective data is sparse. This study was performed to evaluate the long -term effectiveness and safety of a new fully covered SEMS for benign biliary strictures.
The purpose of this study is to study the evaluation of the use of metal stents as part of the treatment of benign biliary strictures.
