should observation, drainage, redo thoracoscopy, or thoracotomy be used?
GROUND: Video-assisted thoracoscopic surgery (VATS) is the popular method for treating primary spontaneous pneumothorax (PSP). Nevertheless, the optimal management of pneumothorax recurrence after VATS remains unclear. This study evaluated the efficacies of various treatment methods. METHODS: Between 1992 and 2008, 53 cases of recurrent ipsilateral pneumothoraces were noted after 978 VATS treatments for PSP. The primary treatments included 19 observations, 14 pleural drainages with and without sclerosis, 19 redo VATS, and one thoracotomy. The demographic data and treatment outcomes were collected through retrospective chart reviews. RESULTS: The mean interval between VATS and the first recurrence was 12.8 months. Patients who underwent observation had smaller recurrences than those who underwent pleural drainage or redo VATS. The primary failure rate was 5% (1/19) for observation, 50% (7/14) for pleural drainage, 0% (0/19) for redo VATS, and 0% (0/1) for thoracotomy. After a mean follo
