Using uncovered metallic endoprostheses to treat recurrent benign esophageal strictures

The management of recurrent benign esophageal strictures is a difficult clinical problem, especially in patients who are not surgical candidates. We evaluated the role of uncovered metallic endoprostheses in four patients who had strictures that were resistant to repeated balloon dilatation.

Our preliminary experience indicates that uncovered metallic endoprostheses can be effective in treating a select group of patients who have benign esophageal strictures and for whom multiple dilatations have failed. It is also important to note that epithelial hyperplasia can result in stenoses and recurrent dysphagia.
