Metallic self-expanding stents can now be used to palliate biliary and esophageal malignancies. Their ease of insertion and wide diameter, resulting in improved long-term patency, make them the palliative method of choice for appropriate patients. These stents are now available in covered versions, improving their longevity and ultimately possibly allowing for removal and reinsertion and wider use in benign strictures. This review details appropriate use and results with metallic stents and comparison with standard methods.
