Subcostal uniportal robotic anatomic lung resection: A pilot trial

Robot-assisted thoracoscopic surgery typically necessitates the use of multiple ports. The new single-port robotic system (da Vinci SP system) platform is designed to perform uniportal surgery. The purpose of this clinical trial is to evaluate the feasibility, efficacy, and safety of the da Vinci SP system when used for anatomical lung resection.

Patients diagnosed with clinical stage I lung cancer requiring anatomical lung resections were considered eligible for this trial. The primary outcome measure was the rate of conversion, whereas the secondary objective focused on assessing the incidence of perioperative complications.

The study included 35 patients with a median age of 63 years (range, 48-74 years). Of these, 30 underwent lobectomy and 5 received segmentectomy. All surgeries were successfully performed using a subcostal approach, except for 1 patient, who required a thoracotomy conversion due to bleeding (conversion rate: 2.9%). The median docking time was 2 minutes (range, 1-8 minutes). For the 34 patients who completed uniportal surgery, the median total operating time was 194 minutes (range, 63-405 minutes), whereas the console time was 153 minutes (range, 93-267 minutes). The median number of harvested nodes was 13 (range, 5-37), while the median number of nodal stations was 6 (rang, 4-8). There were no in-hospital fatalities, and the median postoperative stay was 3 days (range, 2-12 days).

This study demonstrates the feasibility and safety of using the da Vinci SP system for anatomical lung resection through a subcostal approach.
