Background: This study aims to compare the effectiveness of single-port and two-port video-assisted thoracoscopic surgery in patients with pneumothorax.

Methods: Between June 2016 and December 2018, a total of 44 patients (39 males, 5 females; mean age 27.0±9.5 years; range, 15 to 60 years) who underwent video-assisted thoracoscopic surgery due to the spontaneous pneumothorax in our center were retrospectively evaluated. The study population was divided into two groups as the single-port (n=29) and two-port (n=15) procedure according to the number of port entries applied during the operation. Age, gender, number of days of drainage, length of hospitalization, number of days of air leak, the indication of operation, pneumothorax side, type of pneumothorax, duration of operation, and complications were compared between the groups.

Results: Twenty-two patients (50%) were operated on the right side and 22 patients (50%) on the left side. The mean operation time was 81.1±19.2 min, indicating no significant difference between the groups (p=0.053). No significant difference was observed in the number of days of drainage, the length of hospitalization, and number of days of air leak between the two groups. Complications developed in eight patients (27.6%) in the single-port group and five patients (33.3%) in the two-port group, indicating no significant difference between the groups (p=0.475).

Conclusion: Our study results show that video-assisted thoracoscopic surgery for the treatment of pneumothorax can be successfully performed via a single-port approach.
