We have experienced 456 cases of spontaneous pneumothorax from January, 1981 to December, 1991 at the department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital. Of these, 102 cases were recurrent pneumothorax. These 102 cases were based on the retrospective clinical analysis, and the results were as follows: The ratio of male to female was 6.2: 1 in male predominance and the old aged patients, over 50 years old, occupied 46.8%a of all patients. Primary spontaneous pneumothorax was 43 cases[42.6%] and secondary spontaneous pneumothorax was 59 cases. The underlying pathology in secondary spontaneous pneumothorax was tuberculosis: 31 cases[30.4%], emphysema and chronic obstructive pulmonary disease: 27 cases[26.1%], Most frequent operative and pathologic findings in the primary and the secondary spontaneous pneumothorax was bullae and blebs at apex. The employed managements were only closed thoracostomy in 41 cases, open thoracot-omy in 61 cases. The operative procedures at thoracotomy were bullectomy or bullae ligation in 37 cases, bullae resection with wedge resection in 8 cases, bullae resection with segmentectomy in 6 cases, bullae resection with decortication in 3 cases, lobectomy in 5 cases, decortication in 2 cases. Complications were subcutaneous emphysema[5 cases], wound infection[1 case], and temporary pulmonary insufficiency[1 cases]
