A prospective comparative study of thoracoscopic transareolar and uniportal approaches for young male patients with primary spontaneous pneumothorax.

Abstract

In this study, we introduce a novel approach, thoracoscopic transareolar bullectomy, for treating young male patients with primary spontaneous pneumothorax (PSP). This approach might be less invasive and cosmetically superior to existing methods. We also prospectively compared transareolar and uniportal approaches. Between April 2018 and July 2019, 40 patients were prospectively assigned to transareolar (n = 21) and uniportal (n = 19) groups. We compared patient characteristics and perioperative results. Approximately 1week or 1year after the operation, postoperative pain was evaluated using a numerical rating scale (NRS), and cosmetic satisfaction was graded on a four-point scale. We found no significant between-group differences in patient characteristics or perioperative results. NRS scores did not differ on postoperative day (POD) 7 (transareolar, 1.8 ± 0.9 vs. uniportal, 1.6 ± 0.9; p = 0.62) or in postoperative month (POM) 12 (transareolar, 1.3 ± 0.5 vs. uniportal, 1.1 ± 0.5; p = 0.18). In terms of cosmetic satisfaction, the transareolar group was more satisfied on POD 7 (transareolar, 3.5 ± 0.6 vs. uniportal, 2.9 ± 0.9; p = 0.02) and in POM 12 (transareolar, 3.8 ± 0.5 vs. uniportal, 3.3 ± 0.9; p = 0.0065). Although the perioperative results of the transareolar and uniportal approaches were similar, the former approach afforded a little better cosmetic satisfaction and might be useful option for young males with PSP.
