Since the begin of the century, the surgery for treatment of pulmonary tuberculosis showed an important evolution. The procedure has proved to be useful in the 20% of patients. It appears that the percentage is drug-resistant or complicated. The authors describe their experience in the years from 1992 to 1997 and, in accordance with the literature in this field, outline the good prognosis to 5 years, with a percentage of 90-96% of non-infected patients. Very important is the time of surgical intervention, the compliance of the medical treatment in the previous 6 months, excepting in the emergency, and the perfect obliteration of pleural cavity to avoid next reinfection and the development of broncopleural fistulas.
