RESUMO
BACKGROUND: Innovations in surgical instruments have made single-port surgery more widely accepted and lead to a reduced demand for surgical assistants. As COVID-19 has ravaged the world, maintaining minimum medical staffing requirements and proper social distancing have become major topics of interest. We sought to evaluate the feasibility of applying the unisurgeon approach in single-port video-assisted thoracoscopic surgery aided by a robotic camera holder. METHODS: Operative time, blood loss, setup time, postoperative hospital stays, and the number of participating surgeons in single-port video-assisted thoracoscopic lung resections were gathered for investigation after the introduction of the ENDOFIXexo robotic endoscope holder system. In this cohort, we collected 213 patients who underwent single port video thoracoscope surgery, including 57 patients underwent robotic endoscope arm assisted surgery and case-matched 52 patients in the robotic arm-assisted group with patients in the human-assisted group through propensity score-matched analysis. RESULTS: In wedge resection, a single surgeon was able to completely operate on all lobes of target lesions. However, for anatomical resections, namely segmentectomy, the success rate was 95%, and for lobectomy, the success rate was only 64%. No significant differences between setup times, blood loss, or operative times between the two groups were observed. CONCLUSIONS: When an experienced uniport surgeon is assisted by a robotic endoscope holder, wedge resection is the most suitable procedure to be performed through unisurgeon single-port video-assisted thoracoscopic surgery without increasing setup time, operative time, or short-term complications. Verification of the technique's applicability for use in anatomic resections requires further investigation.

Background: Few studies have compared robotic-arm-assisted unisurgeon uniportal surgeries with conventional human-assisted uniportal video-assisted thoracoscopic surgeries (VATSs) in terms of surgical efficacy and patient safety. In the present study, we compared the aforementioned surgeries. Methods: We explored two robotic endoscope holders-a passive robotic platform (ENDOFIXexo, EA group) and a pedal-controlled active robotic platform (MTG-100, MA group)-for unisurgeon uniportal surgeries and compared the surgical outcomes with those of human-assisted uniportal surgeries (HA group) in 228 patients with a lung lesion (size, <5 cm). The primary parameters for this comparison were surgical efficacy, patient safety, and short-term patient outcomes. Results: No significant differences were observed among the EA, MA, and HA groups. The success rate of robotic-arm-assisted unisurgeon uniportal wedge resection was 100%, regardless of the group. No major differences were noted in preparation time between the EA and MA groups. Segmentectomy was more favorable in the EA group than in the MA group. The rates of surgical conversion were 5% and 60% in the EA and MA groups, respectively. The EA and MA groups did not differ considerably from the HA group in terms of postoperative complications. Conclusions: Unisurgeon uniportal wedge resection may be effectively performed using a robotic endoscope holder, without the need for any human assistants with an expert hand. However, the rate of surgical conversion increases with the complexity of uniportal anatomic resections. The passive platform appears to be more suitable for unisurgeon uniportal surgery than the active pedal-controlled platform given the equipment in contemporary operating rooms.
RESUMO
The video-assisted thoracoscopic surgery (VATS) for major pulmonary resections has evolved in a period of only 7 years from 3-4 incisions to a single incision approach. However, Uniportal VATS approach is different from other forms of minimally invasive thoracic surgery, and the technique of lung exposure and stapler insertion through a single hole should be learned step by step. The main advances of uniportal VATS during the last years are related to improvements in surgical technique, evolving to a concept of "advanced VATS instrumentation", and implementation of new technology. One recent advance in uniportal VATS is the possibility of using a robotic or pneumatic articulated arm that holds the camera stable and no needs a surgical assistant. This is called "unisurgeon uniportal VATS" in where the surgeon has more freedom of movements and eliminates the fatigue of assistant holding the camera. We are still in the beginning of the "unisurgeon era" that probably will be more popular in the next coming years thanks to the Implementation of wireless cameras and graspers by means of magnetic control.
