Staple line coverage after bullectomy for primary spontaneous pneumothorax: a randomized trial.

Abstract

Thoracoscopic wedge resection is generally accepted as a standard surgical procedure for primary spontaneous pneumothorax. Because of the relatively high recurrence rate after surgery, additional procedures such as mechanical pleurodesis or visceral pleural coverage are usually applied to minimize recurrence, although mechanical pleurodesis has some potential disadvantages. The aim of this study was to clarify whether an additional coverage procedure on the staple line after thoracoscopic bullectomy prevents postoperative recurrence compared with additional pleurodesis.
