The article represents a retrospective review of 15 patients who underwent placement of expandable metallic stents for treatment of benign biliary strictures. The review represents the longest follow-up of any study that has used metallic stents for benign strictures. The study's mean follow-up of 86.3 months is significantly longer than previously reported durations of 33 months, 32 months, and 36 months.1- 3 Expandable stents have been attractive for palliation of patients who have unresectable lesions due to malignant bile duct invasion or compression of the biliary tree. The metallic stent can be expanded to a larger diameter (8-10 mm) when compared with the small diameter (3-4 mm) plastic stents.
