This systematic review and meta-analysis evaluated single-port versus multi-port video-assisted thoracoscopic surgery (VATS) for bullous lung resection in patients with primary spontaneous pneumothorax. The analysis included 1,151 patients from cohort studies. The primary outcome was not reported, but secondary outcomes included hospital stay, postoperative pain, chest wall paresthesia, operative time, chest tube duration, stapler use, complications, and recurrence.
Single-port VATS was associated with a mean difference of 0.246 days for hospital stay with a 95% CI of 0.075–0.416. Postoperative pain showed a mean difference of 1.100 with a 95% CI of 0.528–1.671. The risk ratio for chest wall paresthesia was 0.580 with a 95% CI of 0.432–0.779. No significant differences were observed for operative time, chest tube duration, stapler use, complications, or recurrence.
The authors acknowledge that included studies were all cohort studies and no randomized trials were available. They state that further randomized trials are needed to establish superiority. The evidence is from cohort studies, and certainty may be limited by study design and heterogeneity. Associations are reported, not causation.

ObjectiveThis meta-analysis evaluates the perioperative safety and comparative efficacy of single-port versus multi-port video-assisted thoracoscopic surgery (VATS) for bullous lung resection in patients with primary spontaneous pneumothorax.MethodsA systematic search of PubMed, Embase, Cochrane Library, and Web of Science was conducted through August 2025 to identify cohort studies comparing single-port (conventional or modified) versus multi-port (double-/triple-port) VATS. Data synthesis was performed using Stata 17.0 with random-effects models to account for inter-study heterogeneity.ResultsThirteen cohort studies (1,151 patients) were included. Single-port VATS was associated with significantly reduced hospital stay [mean difference (MD) = 0.246 days; 95% CI, 0.075–0.416] and a reduction in postoperative pain (MD = 1.100; 95% CI, 0.528–1.671) compared with multi-port VATS. The incidence of chest wall paresthesia was also lower (risk ratio = 0.580; 95% CI, 0.432–0.779). No significant differences were observed in operative time, chest tube duration, stapler use, complications, or recurrence. Subgroup analysis showed that the abbreviated hospital stay was primarily driven by conventional single-port techniques, whereas modified techniques showed no significant difference.ConclusionSingle-port VATS for bullous lung resection is associated with accelerated recovery, attenuated postoperative pain, and a lower incidence of neurological sequelae compared to multi-port VATS, without increasing operative time, complication, or recurrence rates. It represents a safe and feasible alternative, although further randomized trials are needed to establish superiority.
