Between May and December 1991, 12 patients with spontaneous pneumothorax were treated surgically, using video-thoracoscopy. With this technique bullous lesions could be excised in 10 cases and pleurodesis could be performed in all patients. Morbidity and mortality were nil. The cosmetic and functional advantages of video-thoracoscopy were obvious. Long-term results remain to be evaluated. This technique has shown that it is possible in all cases to create pleurodesis (pleural poudrage or pleurectomy) and to treat parenchymatous lesions (excision of bullous systems). This suggests that the long-term results will be the same as those obtained with conventional surgery.
