Stapler blebectomy and pleural abrasion by video-assisted thoracoscopy for spontaneous pneumothorax

Background. This study aims to evaluate the efficacy of video-assisted thoracoscopic surgery (VATS) pleurodesis in the treatment of spontaneous pneumothorax with particular reference to the postoperative period and the rate of recurrence after pleural abrasion. Methods. One hundred and thirty-three patients who underwent VATS management of primary spontaneous pneumothorax were retrospectively reviewed. They were 113 males and 20 females with median age of 26 (range 12-37). Among these patients, 114 underwent VATS for recurrent pneumothorax and 19 for persistent air-leakage at the first episode. During surgical procedure, in 78% of cases, parenchymal blebs were identified and resected by stapler resection. All patients were submitted to pleural abrasion. Results. No intra- or postoperative deaths occurred. Postoperative complications were persistent air-leak for more than 7 days in 6 patients (4.3%) bleeding in 3 patients (2.2%). The median chest-tube duration and hospital stay were 2 (range 2-11) and 3 (range 3-12) days, respectively. Median follow-up period of 53 (range 6-96) months was complete for all patients. Five episodes of recurrent pneumothorax were encountered and 4 of them, because of major entity, required re-do VATS with stapler resection and pleural abrasion: their postoperative period and residual follow-up was uneventful. Conclusions. The goal in the surgical management of spontaneous pneumothorax, which often affects "apparently healthy" young patients, is to secure the less recurrence rate with no mortality and quite null morbidity and functional impairment. VATS stapler resection and pleural abrasion is a safe procedure allowing a good management of the disease with low complication rate, short chest-drain duration, hospital stay and recurrence rate quite similar to those referred for other procedures such as pleural poudrage or limited pleurectomy.
