IntroductionHistorically, surgery for SP has been performed with open thoracotomy. Today video-assisted thoracoscopic surgery (VATS) has replaced open surgery for SP in most centers. Long-term results (i.e. recurrent pneumothorax) following VATS have been debated. In Iceland surgery for SP has been performed with both VATS and limited axillary thoracotomy (LAT). The aim of this study was to compare these two approaches, especially reoperations for prolonged airleakage and late recurrences.Material And MethodsThis is a retrospective non-randomized study on all patients operated first time for SP at our institution between 1991-2005. Out of 210 patients that underwent 234 procedures (160 males, mean age 29 yrs.), 200 had primary SP (95%) and 10 secondary SP. The cases were divided into two groups; 134 VATS procedures and 100 thoracotomies (LAT). Three surgeons performed a LAT and four performed VATS.ResultsWedge resection was performed in all cases and mechanical pleurodesis was added in 25% of the VATS and 67% of the LAT cases. Median operation time was 20 minutes longer for VATS (p=0.006). Reoperations for late recurrent pneumothorax were 10 vs. 3 in the VATS and LAT group, and reoperations for persistent airleakage 3 vs. 0, respectively (p=0.03). Operative mortality within 30 days from surgery was 0%. Median hospital stay was one day longer after LAT.ConclusionReoperations following VATS for SP are more common compared to open thoracotomy, explained by a higher rate of both late recurrent pneumothoraces and prolonged early postoperative airleakage. Both approaches are safe and major complications are infrequent. Hospital stay is shorter after VATS, however, VATS takes longer and the higher reoperation rate is a shortcoming and is of concern.
