Abstract

We report three patiens who inserted an expandable metallic stent (EMS) to bronchial stenosis caused by cancer. Patient 1 who had undergone a subtotal esophagectomy for an esophageal cancer was admitted to the hospital because of dyspnea due to left main bronchial invasion of a reccurent cancer. Tracheal intubation was performed under general anesthesia and then EMS was placed at the site of bronchial stenosis via flexible bronchoscopy under fluoroscopic guidance. The procedure promptly relieved respiratory distress and improved arterial PO2 (51.0mmHg→93.7 mmHg), Hugh-Jones classification (V→III) and Performance Status (4→1). Patient 2 complained of dyspnea dur to left main bronchial invasion of a lung cancer. Insertion of EMS relieved respiratory distress and improved Hugh-Jones classification (V→IV) and Performance Status (4→3). Patient 3 complained of dyspnea due to bilateral main bronchial invasion of a reccurrent esophageal cancer. Insertion of EMS could not relieve respiratory distress. We were able to relieve respiratory distress in two out of three. It is thought that EMS treatment for neoplastic bronchial stenosis is useful for relieving respiratory distress and improving quality of life for the patient.
