ABSTRACT
Primary spontaneous pneumothorax (PSP) is an important disease commonly seen in young males. While incidentally diagnosed cases can be managed conservatively, symptomatic patients often necessitate intervention. Chest tube placement (tube thoracostomy) is commonly used, at least in the USA as a primary treatment modality, which requires hospitalization. On the other hand, needle aspiration (NA) has been widely adopted due to simplicity and reported efficacy and safety. No consensus is reached regarding superiority and/or preferred modality, with a lack of guidelines agreement. Therefore, we conducted an updated meta-analysis of randomized controlled trials comparing NA to tube thoracostomy in patients with symptomatic PSP. Prespecified outcomes were immediate success rate, 12-month recurrence rate, post intervention complications rate, and hospital length of stay. We identified and pooled data from six randomized trials, with a total of 759 patients and a median follow up of 12 months. Our analysis showed that NA and tube thoracostomy have similar immediate success rate and 12-month recurrence rate. We also found that NA has less complication rate, need for surgical intervention, and less hospital stays. In conclusion, our review showed that in symptomatic patients with PSP, NA is as effective as tube thoracostomy regarding immediate success rate and 12-month recurrence rate, with the added benefit of less complications rate and need for surgical intervention.
