Retrievable esophageal stents for benign indications.

Until recently, esophageal stents have not been a realistic option for the management of benign disease owing to difficulty removing the stents and associated high complication rates. However, progress in esophageal stent design has led to the development of retrievable esophageal stents. Clinical experience has shown promise for the management of benign esophageal diseases with retrievable stents, including refractory strictures, esophageal leaks, fistula and perforations. They have been shown to be safe and effective, though stent migration remains a concern. This article reviews the current designs, indications, efficacy and complications of retrievable esophageal stents.
