Long-term follow-up after endoscopic stent therapy for benign biliary strictures.

Background And Aims: Endoscopic therapy holds an important role in the management of benign biliary strictures. This study compares the long-term outcome of stenting therapy depending on the underlying cause of the stricture.

Methods: In a retrospective cohort study, 228 patients with benign biliary strictures were identified using an endoscopic database, hospital charts, and cholangiograms between January 1992 and December 2008.
