Abstract
Expandable metallic stents have become popular in recent years for the treatment of esophageal strictures. While they are undoubtedly of great value in the palliation of malignant strictures and tracheo‐esophageal fistulas, there is concern over their use for the treatment of benign diseases. We report three cases, in which such problems were seen following stent insertion for benign esophageal strictures. All three patients developed further strictures above the stents, one was complicated by a tracheo‐esophageal fistula and two stents (in one patient) migrated distally into the stomach. Two of the patients underwent subsequent esophageal surgery. In both cases, this proved extremely difficult and hazardous because of the intense fibrotic reaction induced by the stents. Expandable mesh stents should not be used for the treatment of benign esophageal strictures without careful consideration of the potential problems, which can include rendering the problem inoperable.
