BACKGROUND:Minimally invasive techniques are increasingly being used in pulmonary segmentectomy and combined subsegmentectomy. However, there are no reports as yet on robotic combined anatomic subsegmentectomy(CAS). Herein, we describe related clinical data and operative techniques and present our early results METHODS: Clinical data on patients undergoing robotic CAS were retrospectively reviewed. A combined subsegmentectomy was defined as the resection of ≥2 subsegments that involved ≥2 adjacent segments. Patients subjected to completely portal robotic CAS were enrolled in this study. RESULTS:Between May 2015 and January 2018, a single surgeon performed completely portal robotic CAS for 16 patients. In the CAS-treated patients, most of the lesions (75%) were located in the right upper lobe, and none required conversion to thoracotomy. Median operative time was 175 min (range, 75-294 min) and mean postoperative hospital stay was 4 days (range, 2-11 days). Although one patient experienced a prolonged air leak, the other 15 recovered uneventfully. Within a median follow-up period of 15 months, there were no deaths or tumor recurrences. CONCLUSIONS:Completely portal robotic CAS is a safe and effective procedure in a select subset of patients, proving quite suitable for smaller (<2 cm) multi-segment lung cancers, particularly lesions of right upper lobe. A robotics approach facilitates complex and challenging CAS, the disadvantage being lengthy operative times during early acquisition of skills.

BACKGROUND:Prolonged operating room turnover time erodes patient and employee satisfaction and value. METHODS:Lean and value stream mapping was applied to three operating room teams at an academic health center in New York City and a solution called Performance Improvement Team (PIT Crew) was piloted. RESULTS:Overall, 10% of operating room turnover steps were considered non-valued and were eliminated and 25% of previously sequential steps were performed synchronously. Seven institutional dogmas were eliminated, and three hospital policies were changed. After 35 pilot turnovers, median operating room turnover time improved from 37 minutes (range 26-167) in historical matched controls to 14 minutes (range 10-45, p<0.0001) for the PIT Crew. Cost of the PIT Crew was $1,298 daily and estimated return on investment was $19,500 per day. CONCLUSIONS:Lean and value stream mapping identifies non-valued steps in operating room turnover and affords opportunities for efficiency. Once institutional rules and dogma are changed, culture and workflow improve and turnover time significantly improves. This process adds cost but is profitable. Scalability and sustainability is under further study, as is the "halo effect" on the culture in other non-PIT Crew operating rooms.

The appropriate implementation of new technology, root cause analysis of "imperfect" outcomes and the continuous reappraisal of postgraduate training are needed to improve the care of tomorrow's patients. Healthcare delivery remains one of the most expensive sectors in the United States and the application of new and expensive technology that is necessary for the advancement of this complex specialty must be aligned with providing the best care for our patients. There are a several pathways to innovation; one is partnering with industry and the other is the investigational laboratory. Innovation and the funding thereof come from both the public and the private sector. The majority of new trials that are likely to impact cardiothoracic surgery are industry sponsored trials to meet the requirements necessary for regulatory approval. Cost considerations are paramount when considering integration of innovative technology and treatments into a clinical cardiothoracic surgical practice. The value of any new innovation is determined by the quality divided by the cost, and lean initiatives maximize this equation. The importance and implications of conflict of interest (COI) has been a concern for physicians particularly when new technology or procedures are being incorporated into clinical practice and full disclosures by medical professionals and others involved are essential. Our "societies" and "associations" provide a platform for presentation and peer-reviewed discussion of new procedures, innovations, and trials, etc. and provide a venue for the sharing of knowledge on the highest quality patient care through education and research.

We are honored to have been invited to write this piece entitled, "How to get the most out of your trainees in robotic thoracic surgery". Perhaps a better question is "How can we optimally coach and inspire each resident and/or fellow to maximize their value and potential as people, physicians and surgeons during the span of their career?". As surgeons, we must recognize some of the subtle differences in alignment between ourselves and our trainees, appreciate the value of the trainee within our profession, understand that there is variability to the coaching style that each trainee best responds to, and acknowledge that the success of the people we train-which may be our only true legacy-depends on how we engage and inspire them.

Enhanced recovery after surgery is well established in specialties such as colorectal surgery. It is achieved through the introduction of multiple evidence-based perioperative measures that aim to diminish postoperative organ dysfunction while facilitating recovery. This review aims to present consensus recommendations for the optimal perioperative management of patients undergoing thoracic surgery (principally lung resection). A systematic review of meta-analyses, randomized controlled trials, large non-randomized studies and reviews was conducted for each protocol element. Smaller prospective and retrospective cohort studies were considered only when higher-level evidence was unavailable. The quality of the evidence base was graded by the authors and used to form consensus recommendations for each topic. Development of these recommendations was endorsed by the Enhanced Recovery after Surgery Society and the European Society for Thoracic Surgery. Recommendations were developed for a total of 45 enhanced recovery items covering topics related to preadmission, admission, intraoperative care and postoperative care. Most are based on good-quality studies. In some instances, good-quality data were not available, and subsequent recommendations are generic or based on data extrapolated from other specialties. In other cases, no recommendation can currently be made because either equipoise exists or there is a lack of available evidence. Recommendations are based not only on the quality of the evidence but also on the balance between desirable and undesirable effects. Key recommendations include preoperative counselling, nutritional screening, smoking cessation, prehabilitation for high-risk patients, avoidance of fasting, carbohydrate loading, avoidance of preoperative sedatives, venous thromboembolism prophylaxis, prevention of hypothermia, short-acting anaesthetics to facilitate early emergence, regional anaesthesia, nausea and vomiting control, opioid-sparing analgesia, euvolemic fluid management, minimally invasive surgery, early chest drain removal, avoidance of urinary catheters and early mobilization after surgery. These guidelines outline recommendations for the perioperative management of patients undergoing lung surgery based on the best available evidence. As the recommendation grade for most of the elements is strong, the use of a systematic perioperative care pathway has the potential to improve outcomes after surgery.

During minimally invasive pulmonary resection, it is often difficult to localize pulmonary nodules that are small (<2 cm), low-density/subsolid on imaging, or deep to the visceral pleura. The use of near-infrared fluorescence (NIF) imaging for localizing pulmonary nodules using indocyanine green (ICG) contrast is an emerging technology that is increasingly utilized during pulmonary resection. When administered via electromagnetic navigational bronchoscopy (ENB), ICG can accurately localize pulmonary nodules. When injected intravenously (IV), ICG can also help delineate the intersegmental plane. Research is ongoing regarding the utility of ICG for identification of the sentinel lymph node in lung cancer.
