Abstract
BackgroundPrimary spontaneous pneumothorax (PSP) commonly occurs in adolescents, most commonly in males, and has recurrence rates between 20% and 60%. Surgical therapy has long been debated regarding its role in preventing recurrence, with no current consensus on guidelines for care. The purpose of this study is to examine the effect of treatment type on recurrence rates in pediatric PSP. MethodsThis is a single-institution, institutional review board–approved retrospective analysis of patients aged 1 to 18 diagnosed with their first occurrence of PSP between 2009 and 2017. Patient demographics, hospital course, and outcomes over a 2-y period were collected. Patients were divided into nonoperative (oxygen therapy only) management, chest tube placement, and surgical management. The primary outcome was the recurrence rate. ResultsSixty-four patients diagnosed with PSP met inclusive criteria. The mean age was 15.5, and 48 (75%) of patients were men. Twenty-one patients (33%) underwent nonoperative treatment, 24 patients (37.5%) underwent operative treatment with video-assisted thoracoscopic surgery or open thoracotomy, and 19 patients (30%) underwent chest tube or pigtail placement alone. Fifteen patients (23.4%) experienced a recurrence within 2 y: 6 patients (29%) from the nonoperative treatment group, 4 (21%) who were treated with the chest tube only, and 5 (21%) who underwent video-assisted thoracoscopic surgery or open thoracotomy. No statistically significant difference in recurrence rates was found between treatment groups. Pneumothorax size was found to differ between treatment type; larger pneumothoraces were more likely to undergo surgical intervention (P = 0.0003). Smaller pneumothoraces were associated with higher rates of recurrence on multivariate logistic regression analysis (P = 0.046). ConclusionsRecurrence of PSP in adolescents was found to be 23.4% after 2-y follow-up. Smaller-sized pneumothoraces were associated with higher rates of recurrence, but treatment type did not significantly affect recurrence rates.
