Robot‐assisted thymectomy in large anterior mediastinal tumors: A comparative study with video‐assisted thymectomy and open surgery

Background The aim of this study was to evaluate the safety and effectiveness of robot‐assisted thymectomy (RAT) in large anterior mediastinal tumors (AMTs) (size ≥6 cm) compared with video‐assisted thymectomy (VAT) and open surgery. Methods A total of 132 patients with large AMTs who underwent surgical resection from January 2016 to June 2022 were included in this study. A total of 61 patients underwent RAT, 36 patients underwent VAT and 35 patients underwent open surgery. Perioperative outcomes were compared. Results There were no significant differences in tumor size (p = 0.141), or pathological types (p = 0.903). Compared with the open group, the RAT and VAT groups were associated with a shorter operation time (115.00 vs. 160.00, p = 0.012; 122.50 vs. 160.00, p = 0.071), and less blood loss (50.00 vs. 200.00, p
