Medical thoracoscopy under local anesthesia with simple talc poudrage is a safe and cost-effective technique to prevent recurrences in the case of primary spontaneous pneumothorax. Pathogenesis of primary spontaneous pneumothorax, i.e. a pneumothorax occurring without any underlying lung disease, remains unclear; there is no proof that the air leak leading to air escape into the visceral pleura is located in blebs or bullae visualized during the procedure. Therefore we do not have any evidence that blebs or small bullae cauterization or resection adds any further benefit to pleurodesis. Pulmonologists doing thoracoscopic talc pleurodesis should learn to better control pain due to thoracoscopic talcage as it has been shown that thoracoscopic talcage is not more painful than a chest tube drainage in patients providing they receive at least some opioids. There is also a debate on the best surgical approach to treat pneumothorax but minithoracotomy with pleurectomy remains the gold standard although more expensive and associated with some morbidity or mortality.
