Abstract
We reviewed our experience on video-assisted thoracoscopic surgery (VATS) from our first 100 cases of primary spontaneous pneumothorax (PSP) performed at our institution from September 1992 to January 1994. Apical bullae were identified in 87% of cases. Mechanical pleurodesis with Marlex mesh was performed on all patients. Excision with endoscopic staple cutter was performed in 69 cases; an endoloop was used in five cases; ablation with an argon beam coagulator (ABC) was done in six cases; excision with endoscopic suturing occurred in seven cases; and mechanical pleurodesis alone was used in 13 cases. The overall median postoperative chest tube duration was 2 days (range 1–25 days) and hospital stay 4 days (range 1–30 days). Complications occurred in 8 cases (8%): 1 wound infection; 1 chest wall bleeding; and 6 persistent air leaks which lasted for more than 10 days (one of which eventually required an axillary thoracotomy for control). Procedure failure with recurrence occurred in three cases (3%) at a mean follow-up of 17 months (range 8–24 months). The ABC group alone was responsible for one recurrence and two persistent leaks. We conclude that with the VATS approach in the treatment of PSP, staple resection of apical bullae is quick and most reliable but costly. Endoloop and hand suturing are applicable to selected patients with small and localized bullae and should be further studied, while our limited experience does not favor ABC as the primary treatment modality.
