Percutaneous transhepatic changing of an endoscopically placed stent

SUMMARYBiliary stents are commonly positioned for the relief of obstructive jaundice secondary to malignancy. It is occasionally necessary to percutaneously replace a biliary stent placed by the endoscopist. This is usually because there has been progression of the tumour, which has prevented further endoscopic access. The technique described has real merit since it can further extend palliation.
