Resection with laser and high frequency cutting loop in tracheo-bronchial diseases

A total of 23 patients have been treated endoscopically during the last three and a half years for a variety of diseases in the tracheo-bronchial tree; nine had a tracheal stenosis. Thirteen patients have been treated by resection with a high frequency cutting loop, eleven with a CO2-laser and one with an argon laser. A total of 44 treatments have been performed. Half of the treatments were given because of various malignant diseases. The results of the treatment of this very mixed group of patients were, as a whole, satisfactory with both CO2-laser and cutting loop. A more precise technique can be applied with the CO2-laser than the cutting loop, though the latter is the more efficient and easy to work with. Care must be taken with the loop because of its greater cutting depth. The argon laser has only limited use in the treatment of diseases in the trachea.
