title: Four-year experience with pleural abrasion using a rotating brush during video-assisted thoracoscopy.
abstract: BACKGROUND
  Due to the high recurrence rate in primary spontaneous pneumothorax (PSP), surgical therapy is currently a well-accepted method of treating this condition. There is no general agreement about the best time for surgical intervention (i.e., after the first or second episode) or the optimal surgical approach,--i.e., tube thoracocenteses, thoracotomy, or video-assisted thoracoscopy (VATS) with or without pleurectomy or pleurodesis. The aim of this study was to verify the efficacy of VATS and mechanical brush pleurodesis using a rotating electrical brush system.
  
  
  METHODS
  We treated 47 patients with PSP between June 1993 and June 1997. Follow-up ranged from 20 to 56 months. There were 38 male and nine female patients with a mean age of 26 years. Emergency thoracocenteses due to tension pneumothorax became necessary in three patients. All patients were treated by VATS and mechanical brush pleurodesis. Wedge resection was done if bullae or blebs were present (68.1%).
  
  
  RESULTS
  Operating time was 20-60 min (mean, 35). There were no intraoperative complications and no conversions to conventional surgery. In the first few postoperative days, postoperative pain was controlled with nonsteroidal antirheumatic drugs and additional morphines. Drainage time was 3-7 days (mean, 4). Hospitalization time was 4-8 days (mean, 5). The recurrence rate was 2.1% (one patient). No postoperative bleeding or wound infection occurred in any of our patients.
  
  
  CONCLUSIONS
  VATS combined with mechanical brush pleurodesis using the electrical brush system is a highly effective and safe treatment for patients with recurrent primary spontaneous pneumothorax.
