[Evaluation of surgical treatment for spontaneous pneumothorax].

To evaluate the effect of surgical treatment for spontaneous pneumothorax, we examined eighty patients who underwent the surgical treatment. Out of these, thirty five patients (53.0%) were the recurrent episode of the disease, since we vigorously chose surgical treatment for the second attack of the disease. Operative complications were observed in 6 cases (7.1%) including 2 cases of lasting air leakage and 1 case of bleeding, pneumonia, wound infection and atelectasis. Postoperative recurrence was not seen. From a viewpoint of prevention of the postoperative recurrence, the surgical treatment is effective and safe method.
