Comparison of Sleeve Lobectomy for Lung Cancer Using Mini-Thoracotomy and an Optimized Robot-Assisted Technique

Objective: To evaluate the clinical significance of an optimized approach to improve surgical field visualization and simplify anastomosis techniques using robotic-assisted sleeve lobectomy for lung or bronchial carcinoma. Method: A total of 26 consecutive patients who underwent sleeve lobectomy between January 2017 and April 2020 were enrolled in the study. The cohort included 11 cases of robotic-assisted surgery (RAS group) and 15 cases of mini-thoracotomy (MT group). RAS was performed via an exclusive optimized approach utilizing the “3 to 4-6 to 8/9” four-port technique. Retrieved demographical and clinical data included operation time, anastomosis time, blood loss, chest drainage time and volume, postoperative pain scores, complications, white blood cell (WBC) levels, and duration of hospital stay and follow-up. Results: No cases of perioperative death were recorded. Compared to MT group, the RAS group had a similar anastomosis time (30.82 ± 6.08 vs 33.20 ± 7.73 min, respectively, p > 0.05) and shorter operation time (189.73 ± 36.41 vs 225.33 ± 38.19 min, respectively, p
