    A simple technique of endoscopic stent exchange using a biliary dilatation balloon is described. The technique is appropriate in patients with bile duct malignancy in whom clogging of a previously placed straight stent has occurred. Balloon assisted exchange has been used in 25 patients to date and minimises the risks of failure of stent reinsertion and the need for further procedures in patients with limited life expectancy.
