Abstract:
BACKGROUND: Fibrostenosis of large airway due to tuberculosis is one of the most perplexing clinical problems not only because it can lead to respiratory failure but also because of difficulty in the management. No one technique, such as balloon dilatation or insertion of self expandable metallic steno, has proved totally satisfactory in the management of fibrostenosis. We evaluated the effect of laser therapy in patient with severe fibrostenosis due to tuberculosis. METHOD: We classified the fibrostenosis to three types by bronchoscopic finding - the diaphragm type: stenosed by fibrous diaphragm, sparing the tracheobronchial wall, the collapse type: stenosed by collapse of the wall due. to destruction of the cartilage, and the combined type: stenosed by nonspecific inflammatory scar tissue within internal lumen with collapse of the wall. We have treated 10 patients complaining dyspnea due to with severe fibrostenosis of the diaphargm or the combined type using a neodymiumyttrium aluminum garnet(Nd-YAG) laser through a flexible bronchoscopy. RESULTS: Eight of the 10 cases improved after laser therapy and maintained during a follow up period of average 31.9 months. All of the cases undergoing laser therapy showed no serious complication to need the therapy. CONCLUSION: The results of our present study indicate that the Nd-YAG laser therapy is an effective and safe method for the management of selective tuberculous fibrostenosis.
