Use of the Viabil Covered Stent in the Treatment of a Benign Biliary Stricture with the Subsequent Development of Acute Pancreatitis

ABSTRACT

The use of bare metal stents for benign biliary strictures is typically avoided due to historically poor long-term patency. Thus, in patients who are not surgical candidates, the management of benign biliary strictures can be a frustrating process. This article describes a patient who developed a common bile duct stricture following a complex endovascular thoracoabdominal aneurysm repair. The stricture was treated with the placement of a covered metallic biliary stent; a procedure complicated by the development of acute pancreatitis.
