Clinical Trial Summary

Primary spontaneous pneumothorax (PSP) defines as presence of air in chest cavity occurs most commonly in young, tall, and smoker men without underlying lung disease.

Trends for PSP treatment tend toward more invasive procedures. Thoracotomy with pleurectomy and bullectomy is definitive treatment of PSP which significantly reduces recurrence probability. This procedure has been reported to cause high rate of morbidity and mortality. Thus video-assisted thoracoscopic surgery (VATS) has become the preferred method for treatment of PSP with recurrence rate of 5-10%. For persistent or recurrent cases, mechanical or chemical pleurodesis have been suggested.

Based on guidelines patients with large size of lesions in CT or with unstable condition should undergo surgical procedure for recurrence prevention but Patients with small lesion size and stable condition can be only observed. Conservative management of PSP is safe and effective, but as mentioned this method has high recurrence rate. On the other hand fear of recurrence can negatively affect patients' quality of life, so that some patients prefer surgical intervention to observation management. Also some studies recommend invasive treatments because of cost effectiveness of this methods.

As mentioned above, chemical pleurodesis is a usual method for treatment in patients with persistent or recurrent spontaneous pneumothorax. This method has been done using variety of chemical agents including tetracycline, minocycline, blood, and talc to irritate pleura. According to different studies tetracycline has the highest efficacy between irritant agents.

In current study, the investigators have aimed to assess tetracycline chemical pleurodesis through tube thoracostomy in prevention of spontaneous pneumothorax in symptom free patients with normal CT-scan following first episode of PSP.
