The uniportal access for robotic thoracic surgery presents itself as a natural evolution of minimally invasive thoracic surgery (MITS). It was developed by surgeons who pioneered the uniportal video-assisted thoracic surgery (U-VATS) in all its aspects following the same principles of a single incision by using robotic technology. The robotic surgery was initially started as a hybrid procedure with the use of thoracoscopic staplers by the assistant. However, due to the evolution of robotic modern platforms, the staplers can be nowadays controlled by the main surgeon from the console. The pure uniportal roboticassisted thoracic surgery (U-RATS) is defined as the robotic thoracic surgery performed through a single intercostal (ic) incision, without rib spreading, using the robotic camera, robotic dissecting instruments and robotic staplers. There are presented the advantages, difficulties, the general aspects and specific considerations for U-RATS. For safety reasons, the authors recommend the transition from multiportal-RATS through biportal-RATS to uniportal-RATS. The use of robotic dissection and staplers through a single incision and the rapid undocking with easy emergent conversion when needed (either to U-VATS or to thoracotomy) are safety advantages over multi-port RATS that cannot be overlooked, offering great comfort to the surgeon and quick and smooth recovery to the patient.

Summary Uniportal video-assisted thoracoscopic surgery may be the approach for any thoracic procedure, from minor resections to complex reconstructive surgery. However, anatomical lobectomy represents its most common and clinically proven usage. A wide variety of information about uniportal video-assisted thoracoscopic lobectomies can be found in the literature and multimedia sources. This article focuses on updating the surgical technique and includes important aspects such as the geometric approach, anaesthesia considerations, operating room set-up, tips about the incision, instrumentation management and the operative technique to perform the 5 lobectomies. The following issues are explained for each lobectomy: anatomical considerations, surgical steps and technical advice. Medical illustrations and videos are included to clarify the text with the goal of describing a standard surgical practice.

Background: Minimally invasive surgery (MIS) is becoming the standard of care for anatomic lung resections. The advantages of the uniportal approach compared to the conventional multiple incision approach, multiportal video-assisted thoracic surgery (mVATS) and multiportal robotic-assisted thoracic surgery (mRATS), have been previously described. However, no research studies comparing early outcomes between uniportal video-assisted thoracic surgery (uVATS) and uniportal robotic-assisted thoracic surgery (uRATS) have been reported. Methods: Anatomic lung resections performed by uVATS and uRATS from August 2010 to October 2022 were enrolled. Early outcomes were compared after propensity score-matched (PSM) analysis by applying a multivariable logistic regression model including gender, age, smoking habit, forced expiratory volume in the first second (FEV1), cardiovascular risk factors (CVRF), pleural adhesions and tumor size.Results: A total of 200 patients who underwent anatomic lung resections by the same surgeon were recruited in this study, including the initial 100 uVATS patients and the initial 100 uRATS patients. After PSM analysis, each group included 68 patients. The comparison of the two groups showed no significant differences according to the TNM stage in patients with lung cancer, surgical time, intraoperative complications, conversion, number of nodal stations explored, opioid usage, prolonged air leak, length of intensive care unit (ICU) and hospitalization, reintervention and mortality. However, there were significant differences concerning the histology and type of resection (anatomic segmentectomies, the proportion of complex segmentectomies and the sleeve technique were significantly higher in the uRATS group), number of resected lymph nodes (significantly higher in the uRATS group), postoperative complications and duration of chest drain (significantly lower in the uRATS group).Conclusions: Judging from the short-term outcomes, our results confirm the safety, feasibility and efficacy of uRATS as a new minimally invasive technique that combines the benefits of the uniportal method and robotic systems.

Uniportal robotic-assisted thoracic surgery pneumonectomy.

Surgical treatment for non-small cell lung cancer (NSCLC) involving trachea and carina is one of the most infrequent and challenging procedures for a thoracic surgeon, requiring careful preoperative assessment, high level management of the airway, advanced surgical technique and appropriate postoperative care. Carinal and tracheal resections with lung sparing, and carinal sleeve pneumonectomy are part of these complex techniques, with a variable rate of morbidity and mortality. To prevent complications, the most important aspect of the technique is for reconstruction to be performed without tension and with a good blood supply. If a complication is suspected, it must be diagnosed at an early stage, and the problem must be handled aggressively to avoid further progression. The majority of cases are performed with an open approach, but under the care of surgeons and anesthesiologists experienced in minimally invasive thoracic procedures, with advanced airway management skills, in high volume referral centers, these procedures can be performed safely with video-assisted thoracic surgery to obtain good postoperative results. In recent years, with the rapid development of uniportal video assisted thoracic surgery (VATS), this approach resulted in shorter postoperative stays, less postoperative pain and faster recovery after surgery, maintaining oncological principles, becoming an excellent alternative for these difficult cases. This article aims to review the specific considerations that involve this kind of tumors, surgical technique and anesthesiology options, and the recent shift to a minimally invasive approach.
