Videothoracoscopic treatment of primary spontaneous pneumothorax: a 6-year experience.
BACKGROUND
Timing and surgical approach in the treatment of primary spontaneous pneumothorax (PSP) are not well defined. The objective of this study is to propose a treatment protocol by videothoracoscopy (VATS) in PSP.


METHODS
From July 1992 to May 1998, 432 patients underwent VATS treatment of PSP. Indications were: recurrent ipsilateral pneumothorax: 322 cases; persistent air leak following a first episode: 93 patients; recurrence following VATS: 16 cases; recurrence following thoracotomy: 1 patient. Vanderschueren's classification was used for staging. Surgical indications were: stages I and II, subtotal pleurectomy or talc poudrage; stages III and IV, stapling or ligation of the bullae and subtotal pleurectomy or talc poudrage. Differences in recurrence rates were calculated to compare the specific procedures.


RESULTS
No postoperative deaths occurred. Complication rate was 4.16%. Conversion rate was 2.3%. Mean follow-up was 38 months (2 to 72 months). Overall recurrence rate was 4.4%. Specific recurrence rates following stapling and talc poudrage were, respectively, 1.27% and 1.79%. Talc poudrage and stapling of the bullae are respectively superior to subtotal pleurectomy (p < 0.0001) and ligation (p < 0.0001).


CONCLUSIONS
Stapling of the bullae and talc poudrage by VATS represent the treatment of choice of PSP.
