Abstract
Background: Because blebs are confirmed in most of the patients undergoing thoracotomy, identification of blebs by high-resolution computed tomography (HRCT) can be proposed as a surgical indication in primary spontaneous pneumothorax (PSP). If an apical bleb is identified, we treat the patient by video-assisted thoracic surgery (VATS). Methods: From May 1995 to September 1997, 61 patients (21.9 ± 4.6 years) were seen for initial episodes of PSP. Only seven showed bullae on simple chest radiography. However, by HRCT, 48 had sizable blebs (>5 mm), and 45 were treated surgically by VATS. Results: The mean duration of chest tube use after surgery was 3.2 ± 1.9 days, and the mean hospital stay was 4.5 ± 1.9 days. Only one recurrence developed 5 weeks after VATS. Conclusions: Our protocol is effective in controlling an initial episode of PSP. It shortens the observation time before definitive surgical treatment, shortens the hospital stay, and decreases the likelihood of recurrence.
