title: Pleurectomy in primary pneumothorax: is extensive pleurectomy necessary?
abstract: BACKGROUND
  The aim of the study was to evaluate the results of parietal pleurectomy in patients with primary spontaneous pneumothorax comparing extensive pleurectomy performed by thoracotomy versus more limited pleurectomy performed by VATS.
  
  
  METHODS
  Records of the patients operated on for primary pneumothorax at Royal Brompton Hospital from January 1994 to April 1997 were retrospectively reviewed. A follow-up questionnaire was sent to patients asking about further pneumothorax and the presence of long-term chest problems on the operated side. A statistical uni- and multivariate analysis was performed searching predictors for postoperative complications, recurrence and chronic chest problems.
  
  
  RESULTS
  Thirty-six patients underwent extensive pleurectomy through a limited postero-lateral thoracotomy (40%, group A), 54 patients had a limited pleurectomy (60%, group B), 50 by VATS and 4 by axillary thoracotomy. Overall, 11 patients had postoperative complications (12.2%). In group A, 4 patients (11.1%) had complications (2 reoperation, 2 air leak >7 days). In group B, 7 patients (12.9%) had complications (1 reoperation, air leak >7 days, 1 wound infection). Two patients experienced recurrent ipsilateral pneumothorax after surgery, both belonging to group B (overall recurrence rate 2.5%, group B 4.1%). Thirteen patients in both groups (respectively 41.9% in group A and 27% in group B) admitted chest problems on the operated side. From statistical analysis, "indication" resulted a predictor of complications (p=0.03) and "thoracotomy" a predictor of long-term chest problems (p=0.03).
  
  
  CONCLUSIONS
  Many theoretical advantages of limited VATS pleurectomy have still to be confirmed and it is reasonable to use it in uncomplicated primary pneumothorax. The superb exposure obtained with thoracotomy and the superiority of extensive pleurectomy in terms of recurrence indicate this approach in case of complicated pneumothorax or when long-term security is of paramount importance.
