An open and shut case for early VATS treatment of primary spontaneous pneumothorax in children.

BACKGROUND

Treatment of primary spontaneous pneumothorax (SP) involves thoracostomy tube (TT) drainage, with surgery reserved for persistent or recurrent air leaks. We hypothesized that the advent of video-assisted thoracic surgery (VATS) would change indications and outcomes for surgical treatment of SP in our centre.

METHODS

We performed a retrospective (1993-2003) review of children treated for SP. Patients with persistent or recurrent air leaks underwent either limited axillary thoracotomy (LAT), 1993-2001, or VATS, 2001-2003. We included the following outcomes: preoperative SP episodes, TT days (that is, patient days with TT in situ, before surgery), length of hospital stay (LOS), narcotic use and freedom from recurrence. We evaluated the predictive value of preoperative CT scans in guiding treatment of the contralateral side.

RESULTS

Among 31 patients with 19 ipsilateral or contralateral recurrences (61%), 11 were managed nonoperatively. Twenty-six surgeries (13 LAT, 13 VATS) were performed in 20 patients, with 9 undergoing bilateral procedures (3 LAT, 6 VATS). VATS patients were treated earlier, had a diminished narcotic requirement postoperatively and had a shorter LOS with an equivalent recurrence rate, compared with LAT patients. The absence of contralateral blebs did not predict freedom from SP on the contralateral side in patients undergoing surgery for ipsilateral SP.

CONCLUSIONS

Compared with LAT, VATS causes less pain, has a shorter LOS and encourages earlier surgical treatment (including prophylactic, contralateral treatment) of SP in children.
