title: Solving the problem of difficult stent removal due to tissue ingrowth in partially uncovered esophageal self-expanding metal stents.
abstract: Partially uncovered stents provide a better fixation to the esophageal wall than fully covered stents, but indication is limited to palliation because stent removal is compromised by mucosal ingrowth. After an unsuccessful attempt to remove a partially uncovered Evolution stent (Cook Medical Inc, Bloomington, IN) we placed a Polyflex stent (Boston Scientific, Natick, MA) inside the first stent, overlapping at the lower part to press the tissue out of the stent mesh. Both stents were easily removed 3 days later. By adopting this procedure to scheduled stent removals, partially uncovered SEMS may be used to prevent the frequently observed migrations of fully-covered stents in the treatment of esophageal perforation or anastomotic leakage.
