A modified technique for palliative resections of malignant endobronchial tumors with the Nd:YAG laser is described. A special tracheoscope was used in conjunction with the instrument guide of a laser bronchoscope. The main advantage of this technique is easy and simultaneous access to both lungs for ventilation and surgical procedures. The method helps to separate surgical from anesthetic manipulations. The experience of over 70 operations using this technique provides evidence that the use of a tracheoscope is a safe and efficient method of endoscopic resections of larger intrabronchial tumors.
