Abstract

Background: The management of contralateral bullae incidentally found in radiological studies is controversial, largely due to the unpredictability of the natural course of incidentally found contralateral bullae. This study aimed to identify the factors associated with the contralateral occurrence of primary spontaneous pneumothorax (PSP), and to characterize the outcomes of contralateral bullae incidentally found in radiological studies.
Methods: From January 2005 to December 2008, 285 patients were admitted to our institution for PSP, and the patients underwent follow-up until August 2012. The relationships between the following variables and contralateral pneumothorax occurrence were evaluated: age, sex, smoking history, body mass index, ipsilateral recurrence, ipsilateral bullae size, the number of ipsilateral bullae, contralateral bullae size, and the number of contralateral bullae.
Results: The study group consisted of 233 males and 29 females. The mean age and mean body index of the patients were 23.85±9.50 years and 19.63±2.50 kg/m2. Contralateral PSP occurred in 26 patients. The five-year contralateral PSP occurrence- free survival rate was 64.3% in patients in whom contralateral bullae were found.
Conclusion: The occurrence of contralateral PSP was associated with younger age, ipsilateral recurrence, and the presence of contralateral bullae. Contralateral PSP occurrence was more common in young patients and patients with recurrent PSP. Single-stage bilateral surgery should be considered if an operation is needed in young patients, patients with recurrent pneumothorax, and patients with contralateral bullae.
