[The value of initial thoracoscopy in the treatment of pneumothorax].

Various methods have so far been used to treat pneumothorax, including rest, needle exsufflation and blind drainage. The results obtained are varied but the recurrence rate is high, averaging 50%. With thoracoscopy, not only can the pleura be explored and the cause of pneumothorax investigated, but specific treatment of the lesions can be carried out in some cases and symphysis can be obtained by pleural poudrage, thereby avoiding recurrences. One-hundred and eleven cases of pneumothorax collected over a 5-year period are reviewed in this study; the results of exploration and those of endoscopic treatments are given and commented upon.
