    Abstract:
    BACKGROUND: We aimed to analyze perioperative complications, postoperative neuropathic pain, and the necessity of epidural anesthesia in uniportal video-assisted thoracoscopic surgery (U-VATS) compared to conventional multiportal VATS (M-VATS) for anatomical lung resection. METHODS: This retrospective study included all patients who underwent elective VATS lobectomy and segmentectomy between April 2016 and December 2019. The exclusion criteria were as follows: age ≤19 years, planned thoracotomy, re-operation in thoracic surgery, median sternotomy, robot-assisted thoracic surgery, simultaneous resection of extrathoracic organs, locally invasive lung tumor with bronchoplasty or angioplasty, past or current neuropathic pain, and a large tumor with a minimum diameter ≥5 cm. M-VATS had 4 ports approach. U-VATS port positions were placed by extending the thoracoscope port of M-VATS. RESULTS: U-VATS patients showed significant differences compared to M-VATS patients: smaller intraoperative bleeding (1 vs. 30 mL; P=0.0010), shorter operative time (141 vs. 183 min; P<0.0001), post-hospitalization (5 vs. 8 days; P=0.0002), fewer complications (23.9% vs. 40.9%; P=0.048), less acute pain, less postoperative neuropathic pain (32.4% vs. 52.1%; P=0.027) and shorter duration of neuropathic pain (30 vs. 60 days; P=0.041). For the postoperative neuropathic pain and pain score until postoperative day 5, there were no differences between the groups with and without epidural anesthesia. CONCLUSIONS: As a single-center initial experience, U-VATS lobectomy and segmentectomy seemed safe and minimally invasive based on not only postoperative neuropathic pain and complications but also time management. U-VATS would provide better pain control, without epidural anesthesia.
