Tracheobronchial and esophageal stentings for central airway and esophageal stenosis are performed as part of strategies to improve pulmonary functions, dysphagia, and quality of life (QOL) in patients with end-stage lung and esophagus. Most of these patients are inoperable or at high risk because of advanced age and cardiopulmonary failure. Severe complications and degeneration in general condition are likely when invasive surgery is performed in these patients. We review the utility, indications and problems in airway and esophageal stenting for severe endobronchial and esophageal stenosis.The QOL of all patients improved dramatically after stenting. Nevertheless, when deciding among alternative stents, physicians treating patients with tracheobronchial and esophageal stenosis should give careful consideration to the benefits and possible complication of each stent. Considering the increasing number of elderly patients, deterioration in medical finances and cost effectiveness, stenting for end-stage patients will be an even more essential modality in the 21st century.
