Purpose: Single-port video-assisted thoracoscopic (VATS) pulmonary wedge resection was reported in 2004. We started using single-port VATS (SPVATS) pulmonary wedge resection in 2017 and compared results between conventional three-port VATS (VATS group) and SPVATS (SPVATS group).
Methods: We identified 145 consecutive patients with VATS group and SPVATS group. Perioperative characteristics including pain and the number of stapler cartridges used were examined as the surgical outcomes, retrospectively.
Results: In all, 66 cases of SPVATS group and 79 cases of VATS group pulmonary wedge resection were compared. The rate of epidural anesthesia (p <0.0001) was significantly higher and operative time (p <0.0001) was significantly longer with VATS group than with SPVATS group. The number of stapler cartridges used, duration of drain insertion, and rate of postoperative complications did not differ significantly between groups. Average numerical rating scale (NRS) score on postoperative day 1 and postoperative day 7 (p <0.0001 each), maximum NRS score on postoperative day 7 (p = 0.0082) and amount of 25 mg tramadol (p = 0.0062) were significantly lower in SPVAS group than in VATS group.
Conclusion: Our results suggest that SPVATS pulmonary wedge resection offers better pain control and cost-effectiveness than three-port VATS pulmonary wedge resection. These findings should contribute to the body of evidence for SPVATS.
