[The role of endoscopic surgery in respiratory tract neoplasia]

Laser therapy--either by contact or non-contact method--can be considered the best palliative option for patients affected by airway obstruction due to malignant tumors considered inoperable and/or in emergency because of inadequate ventilation. The Nd-YAG laser is widely used in endoscopy. From 1988 to September 2002 at the Department of Surgery "P Valdoni" of the University of Rome "La Sapienza" 251 clinical cases affected by airway obstruction caused by primary or metastatic malignant tumors are treated; moreover 76 stents were used. The symptomatological improvement and beneficial changes in functional breathing tests, haemogasanalysis and X-ray findings were registered 48-72 hours after each treatment. The results showed an improvement in functional breathing values especially after treatment of the main airways such as trachea and main bronchi. The therapy offered an acceptable quality of life. A fairly good number of patients may also return to radio and/or chemotherapy (if previously interrupted) and sometimes to radical surgery. In terms of costs-effectiveness, the endoscopic treatment is widely competitive.
