Uniportal video-assisted thoracoscopic surgery (VATS) has proven safe and effective for pulmonary wedge resection and lobectomy. The objective of this study was to evaluate the safety and feasibility of uniportal VATS segmentectomy by comparing its outcomes with those of the multiportal approach at a single center.
The records of 84 patients who underwent VATS segmentectomy from August 2010 to August 2018, including 33 in the uniportal group and 51 in the multiportal group, were retrospectively reviewed and analyzed.
Anesthesia and operative times were similar in the uniportal and multiportal groups (215 minutes vs. 220 minutes, respectively; p=0.276 and 180 minutes vs. 198 minutes, respectively; p=0.396). Blood loss was significantly lower in the uniportal group (50 mL vs. 100 mL, p=0.013) and chest tube duration and hospital stay were significantly shorter in the uniportal group (2 days vs. 3 days, p=0.003 and 4 days [range, 1-14 days] vs. 4 days [range, 1-62 days], p=0.011). The number of dissected lymph nodes tended to be lower in the uniportal group (5 vs. 8, p=0.056).
Our preliminary experience indicates that uniportal VATS segmentectomy is safe and feasible in well-selected patients. A randomized, prospective study with a large group of patients and long-term follow-up is necessary to confirm these results.
