Children with large primary spontaneous pneumothoraxes may benefit from early operative intervention

The initial management of primary spontaneous pneumothoraxes (PSP) in children remains controversial, particularly regarding the timing of operative intervention. This study aimed to identify factors associated with failure of non-operative management of PSP.

A single-center, retrospective review was performed for patients presenting with PSP. Demographics and clinical predictors were collected. Patients successfully managed non-operatively were compared to failed non-operative management. Fischer exact and Mann-Whitney tests were used as appropriate.

Fifty-seven pediatric patients were identified as having PSP. Four patients underwent initial surgical intervention, 60% (n = 34) were successfully managed non-operatively, while 33% (n = 19) failed non-operative management and underwent video-assisted thoracic surgery (VATS). Those who failed were more likely to have PSP > 2 cm on initial X-ray (79% vs. 44%, p = 0.021) and have a persistent air leak for > 48 h (47% vs 6%, p ≤ 0.001). LOS was greater in the failure group (11.5 ± 5.1 vs 3.1 ± 2.5, p ≤ 0.001) as well as higher complication rates (21% vs 0%, p = 0.013).

Our findings suggest that patients presenting with PSP of > 2 cm or have a persistent air leak for > 48 h despite chest tube management are unlikely to be treated by chest tube alone and may benefit from earlier operative intervention.
