title: [Spontaneous pneumothorax. Results of pleural talc therapy using thoracoscopy].
abstract: The aim of this retrospective study is to evaluate the advantage of thoracoscopy and the efficacy of talcage in the treatment of spontaneous pneumothorax (SP). Two hundred cases have been analyzed with a follow-up of 1 to 8 years after the occurrence of the disorder. The ratio man/woman is 4/1. One hundred and forty two pneumothorax are considered as being of idiopathic origin and 58 are associated to bronchopneumopathy, with a mean age of 33 and 56 years, respectively. The percentage of smokers is 69.5% with a mean smoking of 14 packets/years. The endoscopic aspect of pleura is either normal (30%) or shows adhesions (23.5%), blebs (17%) or bullaes (29.5%). Thoracoscopy allowed talc poudrage in 191 patients and allowed to indicate the need for surgery in nine patients. The immediate success rate of talcage is 93.7%. In the group of immediate failure (6.3%), unexpected bullous structures (8/12) are found at tomodensitometry (TDM), as well as during surgery. Late recurrence is reported in 2 cases (1%) at 20 and 25 months. Radiological sequelaes are minimum (9%). Lung function testing in patients with idiopathic pneumothorax (n = 64) shows, before talc poudrage, signs of pulmonary hyperdistension (total lung capacity (TLC) at 116% of predicted values), reflecting the illness pathology, 3 months after talcage a discrete restrictive syndrome (TLC 93%) and one year after the partial recovery of the lost volume (TLC 105%). Tomodensitometry revealed to be complementary to thoracoscopy in secondary SP and very instructive in idiopathic SP after immediate failure of talc poudrage.(ABSTRACT TRUNCATED AT 250 WORDS)
