[Initial experience with a new type of high energy neodymium laser in correcting stenosis of the airway]. / Pierwsze doswiadczenia z zastosowaniem nowego lasera neodymowego w leczeniu zwezen dróg oddechowych.

The aim of the study was to assess the use of a new Nd:YAG laser--mediLas fibertom--in correcting malignant and benign stenoses of the airways. Eighteen patients were included in the study. In 9 these were caused by malignant tumors, in 3 by nonmalignant tumors, in 6 by post-inflammatory stenoses of the airways. Altogether 99 laser sessions were carried out. In patients with malignant diseases complete recanalization was achieved in 6 patients, in 2 partial. One patients did not benefit form the laser procedure. In patients with benign tumors complete recanalization was achieved in all of the patients. In 5 out of 6 patients the post inflammatory stenosis was corrected. Satisfactory results observed after the second, fourth and one year after the initial laser procedure encourage to use this from of therapy in cases of malignant and nonmalignant narrowing of the airways.
