Abstract

BACKGROUND
The benefits of video-assisted thoracoscopic surgery (VATS) have been demonstrated over the past decades; as a result, VATS has become the gold-standard treatment for primary spontaneous pneumothorax (PSP). Due to improvements in surgical technique and equipment, single-port VATS (s-VATS) is emerging as an alternative approach to conventional three-port VATS (t-VATS). The aim of this study was to evaluate s-VATS as a treatment for PSP by comparing operative outcomes and recurrence rates for s-VATS versus t-VATS.
METHODS
Between March 2013 and December 2015, VATS for PSP was performed in 146 patients in Kyungpook National University Hospital. We retrospectively reviewed the medical records of these patients.
RESULTS
The mean follow-up duration was 13.4±6.5 months in the s-VATS group and 28.7±3.9 months in the t-VATS group. Operative time (p<0.001), the number of staples used for the operation (p=0.001), duration of drainage (p=0.001), and duration of the postoperative stay (p<0.001) were significantly lower in the s-VATS group than in the t-VATS group. There was no difference in the overall recurrence-free survival rate between the s-VATS and t-VATS groups.
CONCLUSION
No significant differences in operative outcomes and recurrence rates were found between s-VATS and t-VATS for PSP. Therefore, we cautiously suggest that s-VATS may be an appropriate alternative to t-VATS in the treatment of PSP.
