Background : Secondary spontaneous pneumothorax is caused by various underlying lung diseases, and this is despite that primary spontaneous pneumothorax is caused by rupture of subpleural blebs. The treatment algorithm for secondary pneumothorax is different from that for primary pneumothorax. We studied the recurrence rate, the characteristics of recurrence and the treatment outcomes of the patients with secondary spontaneous pneumothorax.
Material and Method: Between March 2005 to March 2007, 85 patients were treated for their first episodes of secondary spontaneous pneumothorax. We analyzed the characteristics and factors for recurrence of secondary spontaneous pneumothorax by conducting a retrospective review of the medical records.
Result: The most common underlying lung disease was pulmonary tuberculosis (49.4%), and the second was chronic obstructive lung disease (27.6%). The recurrence rate was 47.1% (40/85). The second and third recurrence rates were 10.9% and 3.5%, respectively. The mean follow up period was 21.1±6.7 months (range: 0∼36 month). For the recurrence cases, 70.5% of them occurred within a year after the first episode. The success rates according to the treatment modalities were thoracostomy 47.6%, chemical pleurodesis 74.4%, bleb resection 71% and Heimlich valve application 50%. Chemical pleurodesis through the chest tube was the most effective method of treatment. The factor that was most predictive of recurrence was ’an air-leak of 7 days or more’ at the first episode. (p=0.002)
Conclusion: The patients who have a prolonged air-leak at the first episode of pneumothorax tend to have a higher incidence of recurrence. Further studies with more patients are necessary to determine the standard treatment protocol for secondary spontaneous pneumothorax. (Korean J Thorac Cardiovasc Surg 2008;41:619-624)
