One of the problems affecting metallic biliary stents is the difficulty of removing them, especially after a period of months or if they have migrated. Several approaches have been used to remove both covered and uncovered stents, although with different degrees of effectiveness.

We report two new approaches to removing partially covered stents that migrated proximally and that impacted in the papillary area and distal common bile duct. One stent was removed by papillectomy and the other by using duodenoscopy-guided controlled radial expansion balloon dilation. In both cases, the stents were removed without severe complications for the patient, leaving a good caliber in the stenosis.
