@entity189 is the seventh most common @entity5 worldwide. It is a disease with a poor prognosis; more than half of the @entity1 present with surgically irresectable @entity5 . For such @entity1 , palliative therapy is directed towards the relief of @entity1282 . Expandable metallic stents have recently been developed for use in the oesophagus. These have the advantage of being introduced through small diameter delivery catheters. Once released, they can expand to as much as 25 mm in diameter, potentially allowing @entity1 to consume a normal diet. The current designs of metallic stents include the Strecker stent, the Wallstent endoprosthesis, and the Gianturco-Rosch stent. The Strecker is an uncovered stent while the other two are covered on the outside of the stent with plastic to prevent @entity5 ingrowth. A review of the literature indicates that deployment of these stents is associated with a high technical success rate. Improvement in swallowing function is seen in 83% to 100% of these @entity1 . The overall complication rates are low. However, covered stents are prone to migration while uncovered stents are vulnerable to @entity5 ingrowth. Further improvements in design promise to expand the role of these endoprostheses in the management of @entity189 .
