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.
