Task: Answer Verification
Input (English): Question: Does mechanical pleurodesis reduce recurrence of spontaneous pneumothorax : a randomized trial?
Answer: Thoracoscopic mechanical pleurodesis did not significantly decrease primary spontaneous pneumothorax recurrence compared with simple wedge resection, but intraoperative bleeding and postoperative pleural drainage rates were higher. Younger age increases the risk of recurrence.
Output (English): no
