Abstract
Seventeen patients with malignant tumors of the trachea or main bronchus have been treated with the Nd-YAG laser under topical anesthesia. Eleven of these patients had bronchogenic carcinomas (5 primary and 6 recurrent) and the rest of them had miscellaneous malignant tumors. Two of the 5 patients with primary bronchogenic carcinomas could be resected after laser treatment and the other 3 cases were treated with irradiation. However, 6 patients with recurrent bronchogenic carcinoma, though opening of the air ways could be achieved, did not survive more than 8 months. One patient with recurrent oesophageal carcinoma survived 2 years and 9 months with laser treatment and chemotherapy repeated 3 times. Laser treatment provides an excellent method for resuscitating patients with life threatening obstruction and enables subsequent management to be carefully planned.
