[Spontaneous pneumothorax and its treatment].

It is reported on 111 cases with 123 episodes of spontaneous pneumothorax. Pathological lung changes were found only in 47% of the cases. The percentage of acute lung tuberculosis is minimal. Adequate therapy is the early intercostal constant sucking drainage. Very early thoracotomy should be performed if results of drainage therapy is unsatisfactory or serious complications occur. Pneumothorax after Bülau-drainage recurs in about 16% of the cases. The secure method for prevention of recurrence is thoracotomy.
