[Pathogenesis and immediate results of surgical treatment for spontaneous non-specific pneumothorax].

The paper analyzes the follow-up of 301 patients with spontaneous nonspecific pneumothorax, out of them 103 (52.24%) underwent intraoperative intervention. Bullous emphysema as the most common cause of spontaneous nonspecific pneumothorax was revealed in 74 (71.84%) patients operated on. The paper also describes the pathogenesis of restricted bullous emphysema and the mechanism of occurrence of spontaneous pneumothorax. The most important etiological factors in the development of bullous changes are impaired blood supply in the pulmonary parenchyma and disturbed bronchial patency, which developed in the presence of various obstructive lung diseases. Most (75.72%) patients underwent atypical resection of changed portions of the lung with an YO-60 device in combination with parietal stepwise pleurectomy which prevents a further progression of pulmonary dystrophy and occurrences of relapses of spontaneous nonspecific pneumothorax.
