Prior to 1978, the conventional treatment of pneumothorax generally consisted of conservative therapies such as rest, needle puncture, or thoracic cavity drainage; however, when conservative therapies were ineffective or relapse occurred therapeutic approach, 34 percent (11/32) of our patients required a thoracotomy. Consequently, in 1981, we began to use alternative therapies to reduce the need for thoracotomy. In this report, we describe the results of using a rigid thoracoscope and fiberoptic bronchoscope for the treatment of spontaneous pneumothorax. Initially, we treated 31 of 79 patients with a rigid thoracoscope and electrocoagulation therapy. Therapy was effective in 17 (55 percent) of the patients. Only 13 (16 percent) of the 79 patients required a thoracotomy, which represents a 50 percent reduction in incidence. Of the 14 cases in which therapy was ineffective, the major cause of failure was our inability to view a broad thoracic area and treat all blebs with a rigid thoracoscope. Subsequently, we developed a method using a fiberoptic bronchoscope (FB), which allows an unrestricted view of the thoracic area, in combination with electrocoagulation and fibrinogen or thrombin solution (or both) for the treatment of spontaneous pneumothorax. We treated 19 of 39 patients with the FB method. Treatment was effective in 15 (80 percent) of the patients. Only 4 (10 percent) of the 39 patients required a thoracotomy, which is a reduction of over 60 percent in our original incidence.
