title: Esophageal stenting.
abstract: Malignant obstruction of the esophagus is a debilitating condition, with dysphagia as its main symptom. Many patients present with advanced disease and palliative treatment is the only possibility. Since their widespread introduction 10 years ago, self-expanding metal stents have become accepted as an extremely effective method of palliating malignant dysphagia. Early reports suggesting very low complications have been superseded by results from randomized trials. It is now evident that the complication rate is significant and the need for reintervention can be as high as 50%. Modifications in stent design should reduce this reintervention rate. There are a large number of stent designs now available and it is essential that the interventional radiologist understand the particular strengths and weaknesses of each design, so that the correct choice of stent can be made for a particular patient. The most recent designs include antireflux stents and removable stents. Both represent significant advances and should reduce stent-related complications.
