Double stenting to prevent airway compression in proximal malignant esophageal strictures

Esophageal malignancies presenting with dysphagia from luminal obstruction generally are not resectable for cure, and palliative therapy is the primary focus. Self-expandable metal stents (SEMS) have replaced plastic stents as a primary mode of palliation for malignant esophageal obstruction because of the relative ease of insertion, lower initial morbidity, and larger stent diameter. Self-expandable metal stents are ideal for patients with midesophageal tumors. A majority of patients experience relief of dysphagia with SEMS and dietary modification, but the initial cost is high and early morbidity may be significant. The placement of SEMS across the gastroesophageal junction may result in free reflux that may improve with a stent containing a one-way gastric flap valve. The placement of SEMS in the cervical esophagus, although more difficult, less effective, and less well tolerated, also may be successful. Coated SEMS are a treatment of choice for individuals with tracheoesophageal fistula. Delayed complications occur in up to 40% of patients and include stent migration, bleeding, perforation, fistula formation, and occlusion. Most complications can be managed endoscopically and additional stents may be placed for tumor overgrowth. The comparison of three currently available SEMS for esophageal malignancy show no statistically significant differences with regard to ease of placement, effectiveness, complications, and mortality. The use of SEMS for patients with benign disease is still considered experimental.
