Boston Scientific begins WallFlex trial
This article was originally published in Clinica
A clinical trial to evaluate temporary implantation of Boston Scientific's fully-covered WallFlex biliary stent in the treatment of benign bile duct strictures has been initiated. The 187-patient trial will evaluate the effectiveness of temporary stenting for treating long-term benign biliary strictures, as well as their removal. The study will include patients with bile duct strictures associated with post-liver transplant anastomosis, prior abdominal surgery such as gall bladder removal, and chronic pancreatitis. The stent will remain in the patients for 4-12 months depending on the nature of the stricture, and patients will be followed for five years after stent removal.
