NCT01085747

Brief Summary

Benign biliary strictures can be endoscopically treated with plastic or self-expandable metal stents (SEMS). The purpose of the prospective randomized study is to compare the safety and feasibility of covered SEMS with multiple plastic stents in the treatment of benign biliary stricture caused by chronic pancreatitis.
