Thoracotomy versus VATS: is there an optimal approach to treating pneumothorax?

INTRODUCTION The 2010 British Thoracic Society guidelines recommend that a weighted decision be made by clinicians with regard to surgical intervention for pneumothorax as the video assisted thoracoscopic surgery (VATS) approach is better tolerated by patients but carries a higher rate of recurrence (5% vs 1%). METHODS Overall, 163 patients underwent surgical intervention for pneumothorax at our institution and data were collected prospectively for almost 7 years. Of these, 86 patients underwent VATS under a single surgeon with extensive VATS experience to compensate for the associated learning curve while 79 patients underwent an open procedure. RESULTS There was no statistically significant difference in the recurrence rate between the open and the VATS group (1% vs 3.5%, p=1.0). The VATS group was superior to the open group in terms of reduced postoperative bleeding (7.5% vs 0%, p=0.01), reduced number of intensive care unit admissions (16% vs 0%, p<0.01) and a reduced adjusted length of stay (3 vs 5.5 days, p<0.01). CONCLUSIONS A comparable recurrence rate is attainable with a VATS approach once the learning curve is surpassed and a reduction in morbidity is an additional merit.
