Patients
Over a 2-year period, 91 patients (68 men, 23 women) with a median age of 65 years (range, 28 to 85 years) were referred to our units for investigation and treatment of inoperable central airway stenoses. Eighty-nine patients suffered from advanced malignant disease, and 2 had external compression of a main bronchus caused by benign disease (1 aortic aneurysm, 1 complex deformity of thoracic spine). All patients were first examined by fiberoptic bronchoscopy under local anesthesia to assess the
Insertion Technique and Position of Stents
A total of 38 silicone stents were inserted in the 31 patients. Two patients received two stents simultaneously; one patient with an esophagotracheal fistula received a tracheal and an esophageal stent (Nottingham) and five patients needed stent replacement because of migration or local tumor recurrence. In 42 percent (13/31) of patients, stent insertion was performed as an emergency procedure because of life-threatening tracheobronchial obstruction. The insertion of all stents proved to be
DISCUSSION
Since the first description of his tracheobronchial stent by Dumon,3 the use of these silicone endoprostheses has gained increasing popularity. At our institution, we opted for this stent mainly because of patients' acceptance of a device that was removable. The results in our 31 patients confirmed the ease of insertion and removal of these stents. The fact that they can be fine adjusted with a forceps once they are already deployed presents a clear advantage over other stent types such as the
