ABSTRACT
BACKGROUND: The purpose of this study was to compare the perioperative efficacy and safety of da Vinci robot-assisted thoracoscopic surgery (RATS) for treating anterior mediastinal tumors through the subxiphoid and lateral thoracic approaches under the anesthesia of nontracheal intubation (i.e., laryngeal mask airway). METHODS: We retrospectively analyzed the clinical data of 116 patients with anterior mediastinal tumors treated by RATS under laryngeal mask anesthesia completed by the same operator in the Department of Thoracic Surgery, Gansu Provincial People's Hospital, from October 2016 to October 2022. There were a total of 52 patients including 24 males and 28 females, with an average age of 45.40±4.94 years, in the subxiphoid approach (subxiphoid group). On the other hand, there were a total of 64 patients including 34 males and 30 females, with a mean age of 46.86±5.46 years in the lateral thoracic approach (lateral thoracic group). Furthermore, we have detailedly compared and analyzed the operating time, intraoperative bleeding, and total postoperative drainage in the two groups. RESULTS: All patients in both groups successfully completed resection of the anterior mediastinal tumor without occurring perioperative death. Compared with the lateral thoracic group, the subxiphoid group has more advantages in terms of total postoperative drainage (P=0.035), postoperative drainage time (P=0.015), postoperative hospital stay (P=0.030), and visual analog scale (VAS) pain on postoperative days 2 (P=0.006) and 3 (P=0.002). However, the lateral thoracic group has more advantages in the aspect of docking time (P=0.020). There was no statistically significant difference between the two groups in terms of operative time (P=0.517), total operative time (P=0.187), postoperative day 1 VAS pain score (P=0.084), and postoperative complications (P=0.715). CONCLUSION: The subxiphoid approach of RATS under laryngeal mask anesthesia is safe and feasible for resecting anterior mediastinal tumors. Compared with the lateral thoracic approach, the subxiphoid approach has advantages in terms of rapid postoperative recovery and postoperative patient pain, and patient acceptance is also higher and thus is worth promoting in hospitals where it is available.

Objective To compare the perioperative efficacy and safety of da Vinci robot-assisted thoracoscopic surgery (RATS) for treatment of anterior mediastinal tumors through subxiphoid versus lateral thoracic approaches under the laryngeal mask anesthesia. Methods We retrospectively analyzed the clinical data of 102 patients with anterior-mediastinal tumors treated by RATS under laryngeal mask anesthesia completed by the same operator. Forty-five patients underwent the subxiphoid approach (subxiphoid group), and 57 patients were treated with the lateral thoracic approach (lateral thoracic group). The operating time, intraoperative bleeding, and total postoperative drainage volume in the two groups were compared and analyzed. Results All patients successfully completed resection of the anterior mediastinal tumor without the occurrence of perioperative death. In terms of total postoperative drainage volume, postoperative drainage time, postoperative hospital stay, and VAS pain on postoperative days 2 and 3, the subxiphoid group was more advantages (P < 0.05). No statistically significant difference was found between the two groups in terms of operative time, docking time, total operative time, intraoperative bleeding volume, postoperative day 1 VAS pain score, or postoperative complications (P > 0.05). Conclusion The subxiphoid approach of RATS is safe and feasible for resection of anterior mediastinal tumors. Compared with the lateral thoracic approach, the subxiphoid approach has advantages in terms of rapid postoperative recovery and postoperative pain.
