Study designs of evaluations included in the review
Randomised and non-randomised studies were eligible for inclusion.
Specific interventions included in the review
Studies that compared video-assisted thoracoscopic surgery with open surgery were eligible for inclusion. Where reported, the surgical procedure consisted of (limited) pleurectomy and/or pleural abrasion in all but one of the included studies; this study compared the video-assisted approach with bilobectomy.
Participants included in the review
Studies of patients undergoing surgery for pneumothorax were eligible for inclusion. When reported, the patients' mean age ranged from 20 to 45 years and the proportion of males from 58 to 97%.
Outcomes assessed in the review
Studies that provided data on recurrence rates were eligible for inclusion. Where reported, follow-up ranged from 24 days to 4,961 days. The outcomes assessed by the review were recurrence rates,
post-operative pain and duration of hospital stay.
How were decisions on the relevance of primary studies made?
At least two independent reviewers selected the studies, with any disagreements resolved by consensus. If the same population was evaluated in more than one article, the report with the most complete follow-up was selected.
