Thoracoscopic treatment of spontaneous pneumothorax in children

This study describes the authors experience and results with thoracoscopic treatment of spontaneous pneumotrorax (SP) in 22 children.

A total of 32 thoracoscopic procedures were performed in 22 children. The patients ranged in age from 9 to 21 years at the time of their first thoracoscopy. SP was primary in 9 and secondary in 13 patients. Pleurodesis was performed in all thoracoscopies using talc in 28 and pleural abrasion in 4 procedures. In 2 of these, apical pleurectomy was added to abrasion. Blebectomy was the additional surgical procedure associated with pleurodesis in 4 patients.

Thoracoscopy usually was performed with the patient under general anesthesia. In children with severe respiratory insufficiency, regional anesthesia was used. The mean operative time was 42.6 minutes (range, 8 to 114 minutes). The mean time of postoperative chest tube drainage was 4.6 days (range, 2 to 12 days). Three patients with cystic fibrosis had prolonged air leak lasting longer than 7 days after thoracoscopy. None of them required an additional surgical intervention, and the air leak ceased in 8, 8, and 12 days with continuous suction. One patient required a repeat thoracoscopy for bleeding from an intercostal artery on postoperative day one. The mean follow-up was 4 years (range, 2.5 months to 14 years). There have been 2 partial recurrences (6.25%), both in patients with secondary SP, which were treated by a repeat thoracoscopy and talc pleurodesis.

Thoracoscopic treatment of SP is safe and effective in children. It can be performed under regional anesthesia also in children with severe respiratory insufficiency. Because the complications and recurrences are encountered more frequently in children with an underlying lung disease, special care in surgical manipulation is required in this subgroup of patients with SP.
