Severe coronavirus disease 2019 (COVID-19) can cause acute respiratory failure requiring mechanical ventilation. Venovenous (VV) extracorporeal membrane oxygenation (ECMO) has been used in patients in whom conventional mechanical ventilatory support has failed. To date, published data have focused on survival from ECMO and survival to discharge. In addition to survival to discharge, this study reports 1-year follow-up data for patients who were successfully discharged from the hospital.A single-institution, retrospective review of all patients with severe COVID-19 who were cannulated for VV-ECMO between March 10, 2020 and May 1, 2020 was performed. A multidisciplinary ECMO team evaluated, selected, and managed patients with ECMO support. The primary outcome of this study was survival to discharge. Available 1-year follow-up data are also reported.A total of 30 patients were supported with VV-ECMO, and 27 patients (90%) survived to discharge. All patients were discharged home or to acute rehabilitation on room air, except for 1 patient (3.7%), who required supplemental oxygen therapy. At a median follow-up of 10.8 months (interquartile range [IQR], 8.9-14.4 months) since ECMO cannulation, survival was 86.7%, including 1 patient who underwent lung transplantation. Of the patients discharged from the hospital, 44.4% (12/27) had pulmonary function testing, with a median percent predicted forced expiratory volume of 100% (IQR, 91%-110%). For survivors, a 6-minute walk test was performed in 59.3% (16/27), with a median value of 350 m (IQR, 286-379 m).A well-defined patient selection and management strategy of VV-ECMO support in patients with severe COVID-19 resulted in exceptional survival to discharge that was sustained at 1-year after ECMO cannulation.

Background Our objective is to assess feasibility, safety, and to describe outcomes for patients discharged by postoperative day one (POD1) after robotic segmentectomy and lobectomy. Methods A retrospective analysis of a prospectively collected database of a quality improvement initiative by a single surgeon. Factors associated with discharge by POD1 were evaluated using a multivariate logistic regression model. Results From January 2018 to July 2020, 253 patients underwent robotic anatomic pulmonary resection of which 134 (53%) discharged by POD1, 67% post segmentectomy and 41% post lobectomy. Discharge by POD1 improved with experience and was achieved in 97% of patients post segmentectomy and 68% post lobectomy in the final quartile. Thirty-one (12%) patients were discharged home with a chest tube, including 7 (2.8%) on POD1. On multivariate analysis, never smokers and segmentectomy were associated with discharge by POD1. Conversely, decreased baseline performance status and perioperative complications were associated with discharge after POD1. There were 10 (4.0%) minor morbidities, 6 (2.4%) major morbidities, and no 30 or 90-day mortalities. There were 4 readmissions (1.6%), of which one (0.4%) was after POD1 discharge. Patient satisfaction remained high throughout the study period. Conclusions With experience and communication, select patients can be discharged home on POD1 after robotic segmentectomy and lobectomy with excellent outcomes and high satisfaction. Discharge by POD1 was associated with never smokers and segmentectomy, and inversely associated with decreased baseline performance status and perioperative complications.

Pulmonary function testing remains the central determinant of candidacy for pulmonary resection and indicator of perioperative risk. For patients with borderline pulmonary function, exercise testing can help determine surgical candidacy either via stair climbing or by obtaining a maximum oxygen consumption. The Thoracic Revised Cardiac Risk Index should be used to select patients for further cardiac testing. Patient comorbidities, medications, functional limitations, and smoking status are also requisite assessments of the preoperative evaluation that influence perioperative outcomes. A minimally invasive approach to pulmonary resection reduces perioperative risk and may be of most benefit to patients with borderline pulmonary function.

Hemoadsorption with CytoSorb has been used as an adjunct in the treatment of severe coronavirus disease 2019 (COVID-19)-related respiratory failure. It remains unknown if CytoSorb hemoadsorption will alter sedative and analgesic dosing in critically ill patients on venovenous extracorporeal membrane oxygenation (VV-ECMO). We conducted a retrospective review of patients with severe COVID-19 requiring VV-ECMO for respiratory support. Patients who were enrolled in a clinical study of CytoSorb were compared with patients on VV-ECMO alone. Data were collected for the 72-hour CytoSorb therapy and an additional 72 hours post-CytoSorb, or a corresponding control time period. Sedative and analgesic doses were totaled for each day and converted to midazolam or fentanyl equivalents, respectively. The primary endpoint, change in sedative and analgesic requirements over time, were compared using a two-way mixed analysis of variance. Of the 30 patients cannulated for VV-ECMO for COVID-19, 4 were excluded, leaving 8 patients in the CytoSorb arm and 18 in the Control. There was no effect of CytoSorb therapy on midazolam equivalents over the 72-hour therapy (p = 0.71) or the 72 hours post-CytoSorb (p = 0.11). In contrast, there was a significant effect of CytoSorb therapy on fentanyl equivalents over the first 72 hours (p = 0.01), but this was not consistent over the 72-hours post-CytoSorb (p = 0.23). CytoSorb therapy led to significant increases in analgesic requirements without impacting sedative requirements. Further research is needed to define the relevance of CytoSorb hemoadsorption on critical care pharmacotherapy.

Postoperative air leak is one of the most common complications after pulmonary resection and contributes to postoperative pain, complications, and increased hospital length of stay. Several risk factors, including both patient and surgical characteristics, increase the frequency of air leaks. Appropriate intraoperative tissue handling is the most important surgical technique to reduce air leaks. Digital drainage systems have improved the management of postoperative air leak via objective data, portability, and ease of use in the outpatient setting. Several treatment strategies have been used to address prolonged air leak, including pleurodesis, blood patch, placement of endobronchial valves, and reoperative surgery.

Während der Lungenkrebs weiterhin die häufigste krebsbedingte Todesursache in den USA darstellt, bildet die Chirurgie in kurativer Intention weiterhin eine tragende Säule der Therapie. Seit mehr als einem Jahrzehnt kommen dabei im Rahmen der Lungenresektion bei nicht kleinzelligem Bronchialkarzinom (NSCLC) auch roboterassistierte Systeme zum Einsatz. Zu lokal begrenzteren Formen der Resektion wie z.B. Keilresektionen oder Lobektomien liegen umfangreiche Daten vor, die eine Reduktion der Krankenhausverweildauer und der postoperativen Schmerzen ebenso belegen wie verbesserte Raten der Lymphknotendissektion und des Auftretens von Komplikationen. Das roboterassistierte Vorgehen bietet eine Vielzahl technischer Vorzüge, z.B. bessere Optik, natürliche Handbewegungen für den Operateur bei der Steuerung der Instrumente sowie präzise Identifizierung der Gewebeebenen und entsprechend ergonomischer und sicherere Dissektion. Aufgrund dieser Vorteile wächst auch das Anwendungsspektrum für roboterassistierte Resektionen. In der vorliegenden Übersichtsarbeit werten wir die vorliegenden Daten zu erweiterten Formen der roboterassistierten Lungenresektion aus, insbesondere die Resektion nach Induktionstherapie, Manschetten-Lobektomie und Pneumonekto­mie. Darüber hinaus werden die Indikationen für diese komplexeren Resektionen betrachtet und die Daten und Outcomes aus der Erfahrung anderer Einrichtungen mit diesen Eingriffen wiedergegeben. Abschließend beschreiben wir die Strategie und Sichtweisen in unserer eigenen Einrichtung im Hinblick auf die genannten drei Formen der erweiterten Lungenresektion. Während die Anwendbarkeit und die Sicherheit der roboterassistierten Chirurgie bei diesen komplexen Lungenresektion noch Gegenstand kontroverser Debatten sind, hoffen wir durch Darstellung der vorliegenden Evidenz und Evaluierung der Wirksamkeit und Sicherheit für NSCLC-Patienten zur Klärung beizutragen.

The Thoraguard Surgical Drainage System is a novel device for drainage of air and fluid after cardiothoracic surgery.A three-part study was conducted: a prospective observational safety and feasibility study, a retrospective comparison of patients managed with an analogue drainage system, and a clinician user-feedback survey.Fifty patients underwent robotic pulmonary resection utilizing the Thoraguard system for postoperative drainage. The Thoraguard system detected a higher number of air leaks than an analogue system (36/50, 72%The Thoraguard Surgical Drainage System provides safe and effective drainage post pulmonary resection. Compared to an analogue system, the Thoraguard system detected a higher number of air leaks and was associated with decreased chest tube duration and hospital length of stay. User survey data reported superior air leak detection, display of clinical data, and ease of use of the Thoraguard system.

Proning patients with acute respiratory distress syndrome (ARDS) has been associated with increased survival, although few data exist evaluating the safety and feasibility of proning patients with ARDS on extracorporeal membrane oxygenation (ECMO).A single-institution retrospective review of all patients with ARDS placed on ECMO between March 1 and May 31, 2020, was performed. All proning events were evaluated for complications, as well as change in compliance, sweep, oxygenation, and flow. The primary outcome of this study was the rate major morbidity associated with proning while on ECMO.In total, 30 patients were placed on ECMO for ARDS, with 12 patients (40%) proned while on ECMO. A total of 83 proning episodes occurred, with a median of 7 per patient (interquartile range, 3-9). No ECMO cannula-associated bleeding, cannula displacement, or endotracheal tune dislodgements occurred (0%). Oropharyngeal bleeding occurred twice (50%). Four patients were proned with chest tubes in place, and none had complications (0%). Lung compliance improved after proning in 70 events (84%), from a mean of 15.4 mL/mm Hg preproning to 20.6 mL/mm Hg postproning (Proning in patients with ARDS on ECMO is safe with an associated improvement in lung mechanics. With careful planning and coordination, these data support the practice of appropriately proning patients with severe ARDS, even if they are on ECMO.

Robotic thoracic surgery continues to gain momentum and is emerging as the optimal method for minimally invasive thoracic surgery. As a rapidly advancing field, continued review of the surgical and anesthetic concerns unique to robotic thoracic operations is necessary to maintain safe and efficient practice. In this review, we discuss the intraoperative concerns as they pertain to pulmonary, esophageal, and mediastinal thoracic robotic operations.

The Coronavirus Disease 2019 (COVID-19) pandemic remains a disruptive force upon the health care system, with particular import for thoracic surgery given the pulmonary pathophysiology and disease implications of the virus. The rapid and severe onset of disease required expedient innovation and change in patient management and novel approaches to care delivery and nimbleness of workforce. In this review, we detail our approaches to patients with COVID-19, including those that required surgical intervention, our expedited and novel approach to bronchoscopy and tracheostomy, and our expansion of telehealth. The pandemic has created a unique opportunity to reflect on our delivery of care in thoracic surgery and apply lessons learned during this time to “rethink” how to optimize resources and deliver excellent and cutting-edge patient care.

The adult presentation of a mediastinal arteriovenous malformation is rare. Resection of these lesions are commonly performed via open thoracotomy, with a risk of bleeding from multiple feeding vessels. This report describes a robotic resection of a mediastinal arteriovenous malformation in a 55-year-old man.

Background and aim of the study: Patients with severe coronavirus disease 2019 (COVID-19) develop a profound cytokine-mediated pro-inflammatory response. This study reports outcomes in 10 patients with COVID-19 supported on veno-venous extracorporeal membrane oxygenation (VV-ECMO) who were selected for the emergency use of a hemoadsorption column integrated in the ECMO circuit. Materials and Methods: Pre and post treatment, clinical data and inflammatory markers were assessed to determine the safety and feasibility of using this system, and to evaluate the clinical effect. Results: During hemoadsorption, median levels of interleukin (IL)-2R, IL-6, and IL-10 decreased by 54%, 86%, and 64% respectively. Reductions in other markers were observed for LDH (-49%), ferritin (-46%), D-dimer (-7%), C-reactive protein (-55%), procalcitonin (-76%) and lactate (-44%). Vasoactive-inotrope scores decreased significantly over the treatment interval (-80%). The median hospital length of stay was 53 days (36-85) and at 90-days post cannulation, survival was 90% which was similar to a group of patients without the use of hemoadsorption. Conclusions: Addition of hemoadsorption to VV-ECMO in patients with severe COVID-19 is feasible and reduces measured cytokine levels. However, in this small series, the precise impact on the overall clinical course and survival benefit still remains unknown.

Management of patients with lung cancer continues to be challenging during the COVID-19 pandemic, due to the increased risk of complications in this subset of patients. During the COVID-19 surge in New York City, New York University Langone Health adopted triage strategies to help with care for lung cancer patients, with good surgical outcomes and no transmission of COVID-19 to patients or healthcare workers. Here, we will review current recommendations regarding screening and management of lung cancer patients during both a non-surge phase and surge phase of COVID-19.

While lung cancer remains the most common cause of cancer-related mortality in the United States, surgery for curative intent continues to be a mainstay of therapy. The robotic platform for pulmonary resection for non-small cell lung cancer (NSCLC) has been utilized for more than a decade now. With respect to more localized resections, such as wedge resection or lobectomy, considerable data exist demonstrating shorter length of stay, decreased postoperative pain, improved lymph node dissection, and overall lower complication rate. There are a multitude of technical advantages the robotic approach offers, such as improved optics, natural movement of the operator's hands to control the instruments, and precise identification of tissue planes leading to a more ergonomic and safe dissection. Due to the advantages, the scope of robotic resections is expanding. In this review, we will look at the existing data on extended robotic pulmonary resections, specifically post-induction therapy resection, sleeve lobectomy, and pneumonectomy. Additionally, this review will examine the indications for these more complex resections, as well as review the data and outcomes from other institutions' experience with performing them. Lastly, we will share the strategy and outlook of our own institution with respect to these three types of extended pulmonary resections. Though some controversy remains regarding the use and safety of robotic surgery in these complex pulmonary resections, we hope to shed some light on the existing evidence and evaluate the efficacy and safety for patients with NSCLC.

Robotic systems utilize computer technology and robotic control to perform minimally invasive surgery. Robotic lobectomy has been shown to be safe and effective for benign and malignant pathologies of the lungs. Our technique for right lower lobectomy uses four robotic arms to isolate and divide the pulmonary artery, vein, and bronchus to the right lower lobe. In this chapter, the conduct of operation for robotic right lower lobectomy is reviewed, with detailed description of our evolving techniques, which we have refined over the last decade of performing and teaching robotic thoracic surgery.

The use of telemedicine and telehealth services has grown exponentially over the past decade and has become increasingly relevant and necessary during the coronavirus 2019 (COVID-19) pandemic. There remains ample opportunity to electronically connect cardiothoracic surgeons with their patients during both preoperative and postoperative visits. In this review, we examine the various implementations of telemedicine within thoracic surgery and explore future applications in this quickly developing field.

Background Our objective was to report the incidence, management, and outcomes of patients who developed a secondary pneumothorax while admitted for coronavirus disease 2019 (COVID-19). Methods A single-institution, retrospective review of patients admitted for COVID-19 with a diagnosis of pneumothorax between March 1, 2020, and April 30, 2020, was performed. The primary assessment was the incidence of pneumothorax. Secondarily, we analyzed clinical outcomes of patients requiring tube thoracostomy, including those requiring operative intervention. Results From March 1, 2020, to April 30, 2020, 118 of 1595 patients (7.4%) admitted for COVID-19 developed a pneumothorax. Of these, 92 (5.8%) required tube thoracostomy drainage for a median of 12 days (interquartile range 5-25 days). The majority of patients (95 of 118, 80.5%) were on mechanical ventilation at the time of pneumothorax, 17 (14.4%) were iatrogenic, and 25 patients (21.2%) demonstrated tension physiology. Placement of a large-bore chest tube (20 F or greater) was associated with fewer tube-related complications than a small-bore tube (14 F or less) (14 vs 26 events, P = .011). Six patients with pneumothorax (5.1%) required operative management for a persistent alveolar-pleural fistula. In patients with pneumothorax, median hospital stay was 36 days (interquartile range 20-63 days) and in-hospital mortality was significantly higher than for those without pneumothorax (58% vs 13%, P < .001). Conclusions The incidence of secondary pneumothorax in patients admitted for COVID-19 is 7.4%, most commonly occurring in patients requiring mechanical ventilation, and is associated with an in-hospital mortality rate of 58%. Placement of large-bore chest tubes is associated with fewer complications than small-bore tubes., Visual Abstract

Patients with severe coronavirus disease 2019 (COVID-19) from infection with acute respiratory syndrome coronavirus 2 (SARS-CoV-2), mount a profound inflammatory response and are predisposed to thrombotic complications [1]. Pulmonary vein thrombosis is a rare disease process resulting in pulmonary congestion, infarction, and potential mortality. This report describes a patient with COVID-19 requiring veno-venous extracorporeal membrane oxygenation (VV-ECMO) for hypoxic respiratory failure, who developed hemorrhagic infarction of the right lower lobe. During emergency exploration, the patient was found to have a right inferior vein thrombosis and marked lobar hemorrhage mandating lobectomy.

Background Coronavirus disease 2019 (COVID-19) remains a worldwide pandemic with a high mortality rate among patients requiring mechanical ventilation. The limited data that exist regarding the utility of extracorporeal membrane oxygenation (ECMO) in these critically ill patients show poor overall outcomes. This report describes our institutional practice regarding the application and management of ECMO support for patients with COVID-19 and reports promising early outcomes. Methods All critically ill patients with confirmed COVID-19 evaluated for ECMO support from March 10, 2020, to April 24, 2020, were retrospectively reviewed. Patients were evaluated for ECMO support based on a partial pressure of arterial oxygen/fraction of inspired oxygen ratio of less than 150 mm Hg or pH of less than 7.25 with a partial pressure of arterial carbon dioxide exceeding 60 mm Hg with no life-limiting comorbidities. Patients were cannulated at bedside and were managed with protective lung ventilation, early tracheostomy, bronchoscopies, and proning, as clinically indicated. Results Among 321 patients intubated for COVID-19, 77 patients (24%) were evaluated for ECMO support, and 27 patients (8.4%) were placed on ECMO. All patients were supported with venovenous ECMO. Current survival is 96.3%, with only 1 death to date in more than 350 days of total ECMO support. Thirteen patients (48.1%) remain on ECMO support, and 13 patients (48.1%) have been successfully decannulated. Seven patients (25.9%) have been discharged from the hospital. Six patients (22.2%) remain in the hospital, of which 4 are on room air. No health care workers who participated in ECMO cannulation developed symptoms of or tested positive for COVID-19. Conclusions The early outcomes presented here suggest that the judicious use of ECMO support in severe COVID-19 may be clinically beneficial.

Background There are limited reports on robotic thymectomy for malignant disease. Our objectives are to review our experience and midterm outcomes. Methods We reviewed a single-surgeon prospective database for patients who underwent planned robotic resection for malignancy from January 2010 to June 2019. Results Two hundred thirteen patients underwent resection of an anterior mediastinal mass, all of which were planned for a robotic approach. Of these, 84 (39%) underwent robotic thymectomy for malignant disease. Thymoma was the most common pathology resected (68%). Median tumor size was 4.7 cm (interquartile range, 2.9-6.3), and median operative time was 81.5 minutes (interquartile range, 64-104). All except 1 patient had a complete (R0) resection (98.8%). There were 2 (2.3%) unplanned but elective conversions to open surgery, 1 of which required cardiopulmonary bypass. Median length of stay was 1 day (range, 0-9) with 1 readmission (1.2%). Major morbidity occurred in 3 patients (3.5%), and there were no 30- or 90-day mortalities. In patients with thymoma, follow-up was complete at a median of 32 months (range, 1-98), and 1 patient (1.8%) had an ipsilateral chest recurrence. To date there have been no patient deaths. Conclusions Robotic thymectomy for patients with malignant disease is safe with excellent perioperative outcomes. A robotic approach achieves a high rate of complete R0 resection, even for larger tumors. For patients with thymoma local recurrence is low after midterm follow-up, but longer-term analysis is needed to determine oncologic durability.

Background Our objectives are to report our outcomes and to demonstrate our evolving technique for robotic sleeve resection of the airway, with or without lobectomy, using video vignettes. Methods We retrospectively reviewed a single-surgeon prospective database from October 2010 to October 2019. Results Over 9 years, of 5573 operations 1951 were planned for a robotic approach. There were 755 robotic lobectomies and 306 robotic segmentectomies, and 23 consecutive patients were scheduled for elective completely portal, robotic sleeve resection. Sleeve lobectomy was performed in 18 patients: 10 right upper lobe, 6 left upper lobe, and 2 right lower lobe. Two patients had mainstem bronchus resections and 2 underwent right bronchus intermedius resections that preserved the entire lung. One patient had a robotic pneumonectomy. One operation was converted to open thoracotomy because of concern for anastomotic tension in a patient who received neoadjuvant therapy. All patients had an R0 resection. In the last 10 operations we modified our airway anastomosis, using a running self-locking absorbable suture. The median length of hospital stay was 3 days (range, 1-11), with no 30- or 90-day mortalities. Within a median follow-up of 18 months, there were no anastomotic strictures and no recurrent cancers. Conclusions Our early and midterm results show that a completely portal robotic sleeve resection is safe and oncologically effective. Trhe technical aspects of a robotic sleeve resection of the airway are demonstrated using video vignettes.

During minimally invasive pulmonary resection, it is often difficult to localize pulmonary nodules that are small (

OBJECTIVE: Recent industry studies have projected a deficit in cardiothoracic surgeons by 2030. Little is known about the difficulties of the job search process after cardiothoracic training. The purpose of this study is to explore the current practices of first job hunt and contract negotiation for young cardiothoracic surgeons, and to identify the gaps in resources available to applicants. METHODS: In October 2017, a 56-question survey was emailed to recent (2013-2017) board-certified cardiothoracic surgeons in the US inquiring about their experience securing their first cardiothoracic job. The survey was administered via REDCap and responses were accepted over three months. RESULTS: Response rate was 12.8% (61/475). The majority of cardiothoracic program graduates (86.9%) interviewed for jobs between October and March of their final cardiothoracic training year, and 79.7% of contracts were signed prior to completing training. Sixty-four percent of respondents negotiated their first contract. The most influential factor in job selection was partner mentorship. Average starting pre-tax salary for respondents was $375,588 (± $107,265). Over half of respondents reported needing more resources and support for the identification (59%) and comparison (54.1%) of job opportunities, contract negotiation (70.5%), and salary guidelines navigation (77%). CONCLUSION: Very little guidance exists to support the search and securing of young cardiothoracic surgeons’ first employment. Resources, whether institutional or organizational, are sparse and difficult to tailor to individual needs. Given the potential ramification of early career decisions, focused support is needed to remediate the lack of preparation available to the newest generations of cardiothoracic surgeons.

Cutibacterium acnes is an anaerobic bacterium commonly thought of as a culture contaminant rather than a pathogen. We present a case of Cutibacterium acnes pericarditis in a 22-year-old immunocompetent woman managed with surgical pericardial window and a 4-week course of penicillin G and review related literature on Cutibacterium acnes pericarditis.

Background The objectives of this study were to present outcomes of robotic segmentectomy and the investigators' preferred technique for nodule localization using indocyanine green both bronchoscopically and intravenously. Methods This study was a retrospective review of a consecutive series of patients scheduled for robotic segmentectomy from a single surgeon's prospectively collected database. Results Between January 2010 and October 2018, there were 245 consecutive patients who underwent planned robotic segmentectomy by one surgeon. Of these 245 patients, 93 (38%) received indocyanine green by electromagnetic navigational bronchoscopy, and all 245 received intravenous indocyanine green. Median time for navigational bronchoscopy was 9 minutes. Navigational bronchoscopy with indocyanine green correctly identified the lesion in 80 cases (86%). The preferred technique was as follows: 0.5 mL of 25 mg of indocyanine green diluted in 10 mL of sterile water given bronchoscopically, followed by a 0.5-mL saline flush, staying at least 4 mm from the pleural surface. The remaining 9.5 mL of indocyanine green was administered intravenously after pulmonary artery ligation. An R0 resection was achieved in all 245 patients, a median of 17 lymph nodes were resected, and the average length of stay was 3.1 days (range, 1 to 21 days). Major morbidity occurred in 3 patients, and there were no 30- or 90-day mortalities. Conclusions Robotic segmentectomy is safe, with excellent early clinical outcomes. In this series, electromagnetic navigational bronchoscopy and indocyanine green localization were efficient and effective at identifying the target lesion. Intravenous indocyanine green delineated the intersegmental plane.

INTRODUCTION Robotic lobectomy is an increasingly common surgical approach for anatomic lung resection. Over the last decade, robotic lobectomy has shown to be safe, with oncologic efficacy similar to lobectomy via thoracotomy or video-assisted thoracoscopic surgery (VATS). Comparative analysis between these modalities is an active area of investigation. While initially expensive, the costs of a robotic platform decrease as the number of operations performed increases, length of stay is shortened, and postoperative morbidity is reduced. Moreover, the added cost has value which is defined over long periods of time. Areas covered: The clinical technique and optimal conduct of lobectomy is explained in granular detail for all five types of lobectomies. The advantages and disadvantages of a robotic platform are analyzed, including a review of the recent literature. Expert commentary: The number of robotic pulmonary resections performed has tripled in the past two years. Anticipated developments in robotic surgery include improvements in robotic training, continued refinement of robotic instrumentation, and additional adjunctive technologies. The overall costs of robotic surgery will decrease, in part, due to increasing competition as additional companies enter the market.
