Late migration of a self-expandable metal stent and successful endoscopic management

Abstract

The first successful implantation of an expandable stent for esophageal cancer was reported in 1990.1 Further experience has shown that self-expanding metallic stents (SEMS) are useful for managing malignant esophageal obstruction.2-5 There is general agreement with regard to their ease of insertion for both operator and patient when compared with rigid plastic endoprostheses. Although the results of an observational study raised a question of whether the complication rate associated with their use is lower than that of plastic stents,6 prospective, randomized trials have suggested a safer profile for SEMS.
