Objectives: To review the literature for justification of thoracoscopic management of blebs in children.
Methods: PubMed database was reviewed for articles in English, Portuguese and Spanish using the key words "thoracoscopy", "bleb" and "child". Data was collected for age, gender, type of surgery performed, operating time, conversions, complications, recurrences, follow-up and mortality.
Results: Eleven studies with total 266 patients were included (27 bilateral cases; n = 293 surgeries). Median age was 15.7 y (range 11-18 y), 225 were male (87.9%) and 31 were female (12.1%) patients. Endo GIA™ was used in 10 cases, Endoloop® in 11 surgeries, unspecified stapler devices in 150 procedures and, in 122 surgeries, instruments were not mentioned. Pleurodesis was performed in 213 (72.7%) cases. There were 5 (1.7%) conversions (adhesions n = 3, bleeding n = 1, camera failure n = 1). Complications were documented in 8 (2.7%): pneumothorax after chest tube removal 4 (drain reinsertion n = 3, reoperation n = 1); prolonged air leak 3, all submitted to che pleurodesis; bleeding requiring reoperation 1. Recurrence occurred in 25 (8.5%): 10 re-operation, 7 conservative management, 2 chemical pleurodesis, 2 chest tube reinsertions and in 4 the management was not specified. The median follow-up was 46.1 mo (range 3 mo-11 y). There were no lethal outcomes.
Conclusions: Although data is scarce on specific instruments used, pleurodesis is performed in 70% of cases. Irrespective of this, thoracoscopic resection of blebs can be safely offered as it has a low complication and conversion rates and no mortality.
