RESUMO
@#Objective To compare the clinical efficacy and safety of da Vinci robot with totally no tube (TNT) versus subxiphoid video-assisted thymectomy surgery (SVATS) in the treatment of thymic tumors. Methods From 2019 to 2021, a retrospective analysis was conducted on patients with thymic tumor resection in the Department of Thoracic Surgery, General Hospital of Northern Theater Command. All patients underwent total thymectomy and mediastinal fat removal, and they were divided into a TNT group and a SVATS group according to the operation method. The intraoperative blood loss, conversion rate, postoperative visual analogue score (VAS), postoperative hospital stay time and postoperative complications were compared between the two groups. Results We finally included 435 patiets. There were 168 patients with 83 males and 85 females at an average age of 61.920±9.210 years in the TNT group and 267 patients with 147 males and 120 females at an average age of 61.460±8.119 years in the SVATS group. There was no death or postoperative myasthenic crisis in both groups. There was no statistical difference in postoperative hospital stay (1.540±0.500 d vs. 3.400±0.561 d, P=0.000), intraoperative blood loss (13.450±5.498 mL vs. 108.610±54.462 mL, P=0.000), postoperative 24 h VAS score (4.960±1.757 points vs. 3.600±1.708 points, P=0.000), or postoperative complication rate (3.0% vs. 11.6%, P=0.001). Conclusion TNT is a more efficient, safe, and effective surgical approach for treating thymic tumors, which can shorten hospital stay time and reduce postoperative complications. However, SVATS can minimize postoperative pain.
