  • Title: Advances in esophageal stenting: the evolution of fully covered stents for malignant and benign disease.
    Author: Schembre D.
    Journal: Adv Ther; 2010 Jul; 27(7):413-25. PubMed ID: 20586003.
    Abstract:
    Self-expanding metal stents have become a leading palliative therapy for dysphagia resulting from esophageal, proximal gastric, and mediastinal cancers. Increasingly, fully covered self-expanding plastic stents and now fully covered metal stents have been used to treat a variety of benign esophageal conditions as well as cancer. Several stent designs are available in the United States and many more internationally. Each design has advantages and limitations. Knowledge of the indications for esophageal stenting and the common side effects associated with different designs allows physicians to choose the best stent for a given condition as well as to anticipate complications such as stent migration or restenosis. Compared with partially covered stents, newer, fully covered metal stents may promote less granulation tissue and subsequent stenosis and may be removable even after several weeks. However, the tradeoff may be more frequent migration. Interest in fully covered metal stents in place of fully covered plastic stents for use in strictures and leaks has also grown, despite the lack of a formal indication for metal stents in benign disease. Unfortunately, rigorous studies of newer stent designs are currently lacking.
