[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.

Morphologic grading of emphysema is useful in the selection of candidates for unilateral or bilateral reduction pneumoplasty.

Objective: Radiologic morphology of emphysema proves useful in the selection of candidates for bilateral reduction pneumoplasty. We developed a simple morphologic grading system capable of identifying subsets of patients who had maximal functional improvement after unilateral or bilateral operation.

Methods: Fifty-two patients who underwent unilateral (n=34) or bilateral (n=18) reduction pneumoplasty were evaluated.

[Treatment via laser of airway obstructions].

The Nd-YAG laser is widely used in endoscopy. Laser therapy either by contact or non-contact method, can be considered the best palliative option for patients affected by airway obstruction due to endoluminal malignant tumours. It aims at the improvement of breathing conditions and symptomatology.
