Can single-incision thoracoscopic surgery using a wound protector be used as a first-line approach for the surgical treatment of primary spontaneous pneumothorax? A comparison with three-port video-assisted thoracoscopic surgery

Abstract

OBJECTIVE: In this study, we compared single-incision thoracoscopic surgery (SITS) using a wound protector, with three-port video-assisted thoracoscopic surgery (VATS) to investigate whether it can be used as a first-line approach for primary spontaneous pneumothorax (PSP). METHODS: We retrospectively reviewed and analyzed the medical records of patients who were diagnosed with PSP in our hospital between March 2013 and January 2014 who underwent SITS (n = 37) or three-port VATS (n = 23). RESULTS: There was no significant difference between the patients who underwent SITS and those who underwent three-port VATS in terms of their age, gender, number of episodes, pneumothorax laterality, operation time, number of wedge resection, duration of post-operative hospital stay and post-operative drainage, and complications. The post-operative pain score was significantly lower in the SITS group compared to the three-port group at both 24 and 72 h (3.9 ± 1.2 vs. 5.2 ± 1.3, p = 0.022, 2.5 ± 1.5 vs. 3.9 ± 1.8, p = 0.03). There was no statistically significant difference in the use of additional intramuscular analgesia between the two groups, but it was lower in the SITS group. CONCLUSIONS: We consider that SITS using a wound protector is an appropriate first-line surgical approach for PSP.
