OBJECTIVE: There is very little experience regarding recurrences following videothoracoscopic (VATS) treatment of primary spontaneous pneumothorax. We report our experience with 19 patients who underwent redo-VATS to evaluate the feasibility of such surgical approach. METHODS: From July 1, 1992 to September 1, 2000, out of 2136 VATS procedures performed at our institution, 597 patients (27.94%) underwent VATS treatment of primary spontaneous pneumothorax with a recurrence rate of 3.85% (23 cases). Primary VATS treatment in these patients was: talc poudrage, three cases; subtotal pleurectomy, three cases; ligation of the bullae + subtotal pleurectomy, 12 cases; stapling of the bullae + subtotal pleurectomy, two cases; ligation of the bullae + talc poudrage, one case; stapling of the bullae + talc poudrage, one case. Treatment of the 23 recurrences included: 15 redo-VATS, four standard thoracotomy, three pleural drainage, one bed rest. Four additional redo-VATS were also performed in four patients operated on in different institutions. Redo-VATS showed residual bullae in nine cases and a minimal leaking area in one patient; in the remaining nine patients no lesion was found. Redo-VATS treatment was: stapling of the bullae + talc poudrage in nine patients; suture of the leaking area with a no-knife stapler + talc poudrage in one patient; isolated talc poudrage in the remaining nine patients with no-evidence of bullae or blebs. RESULTS: No mortality was reported; no major complications occurred. The conversion rate in the group of redo-VATS was 5.2% (one patient). At a mean follow-up of 32 months no patient showed recurrent pneumothorax. CONCLUSIONS: In the light of our initial experience, redo-VATS seems to be a promising tool for the surgical therapy of recurrences following VATS treatment of primary spontaneous pneumothorax.
