Conservative and operative management of spontaneous pneumothorax in children and adolescents: Are we abusing of CT?

Abstract

Background: No age-specific pediatric guidelines exist for the management of spontaneous pneumothorax (SP) in children and adolescents. Treatment remains heterogeneous and center dependent. The role of computed tomography (CT) has yet to be defined.

Aims: Review the management of SP in children and adolescents, with emphasis on conservative management and role of CT.

Methods: Retrospective analysis of 61 consecutive patients with SP at single tertiary center. Clinical, radiological, surgical data, follow-up, and outcomes were revised.

Results: First-line management was conservative for 32 (53%) patients and operative for 29 (47%). Asymptomatic/paucisymptomatic patients managed conservatively experienced less first-line treatment failure. Furthermore, the patients needing at least a chest drain or surgery during the follow-up were significantly lower in the conservative group. Conservative and operative patients showed no significant differences regarding ipsilateral recurrences or contralateral occurrences. Of the 61 overall CTs performed, 14 (23%) had an impact on management. Forty-three (70%) patients had at least a CT, in 22 (51%) the CT was positive for blebs. For 10 of these patients (45%) the presence of blebs had an impact on management. Patients with and without blebs showed no differences regarding ipsilateral recurrence, contralateral occurrences, or the need for at least a chest drain or surgery during the follow-up.

Conclusions: First-line conservative management had a significantly shorter hospitalization and better outcome, with a similar incidence of recurrences. The presence of blebs at CT does not predict the risk of recurrence. The CT scan should be reserved for a small number of selected patients who have post-VATS refractory or recurrent pneumothorax.
