Management of the pediatric spontaneous pneumothorax: is primary surgery the treatment of choice?

Abstract

Background: Surgery as the primary management strategy for pediatric primary spontaneous pneumothorax is controversial. This study aims to evaluate the outcomes and effectiveness of management approaches for pediatric spontaneous pneumothorax.

Methods: Outcomes of pediatric patients undergoing initial nonoperative treatment versus video-assisted thoracoscopic surgery with blebectomy and mechanical pleurodesis were compared via a retrospective review.

Results: We identified 96 patients with 108 pneumothoraces. Of 98 pneumothoraces with initial nonoperative management, 37% had surgery during their initial hospitalization for persistent air leak. Of those discharged home without video-assisted thoracoscopic surgery, 40% recurred. Initial nonoperative management resulted in more total hospital days (median: 11 vs 5 days, P < .001). No significant predictors of recurrence were identified on multivariate analysis. Sixty-three percent of all patients ultimately required surgery.

Conclusions: Fewer than 40% of primary spontaneous pneumothorax patients are definitively treated with nonoperative management. A prospective study is needed to determine whether primary surgery with blebectomy/mechanical pleurodesis is a more effective treatment strategy.
