Management of spontaneous pneumothorax: state of the art
For limited pneumothorax in stable patients, rest and observation are recommended. When reoperation is necessary, both repeat VATS and thoracotomy have been performed. In ∼50% of cases, residual bullae or air leaks are found; these are usually stapled or ligated, and pleurodesis by pleurectomy, abrasion or talc poudrage is added.
