Pulmonary Open, Robotic, and Thoracoscopic Lobectomy (PORTaL) Study: An Analysis of 5721 Cases.

OBJECTIVE: The aim of this study was to analyze outcomes of open lobectomy (OL), VATS, and robotic-assisted lobectomy (RL). SUMMARY BACKGROUND DATA: Robotic-assisted lobectomy has seen increasing adoption for treatment of early-stage lung cancer. Comparative data regarding these approaches is largely from single-institution case series or administrative datasets. METHODS: Retrospective data was collected from 21 institutions from 2013 to 2019. All consecutive cases performed for clinical stage IA-IIIA lung cancer were included. Neoadjuvant cases were excluded. Propensity-score matching (1:1) was based on age, sex, race, smoking-status, FEV1%, Zubrod score, American Society of Anesthesiologists score, tumor size, and clinical T and N stage. RESULTS: A total of 2391 RL, 2174 VATS, and 1156 OL cases were included. After propensity-score matching there were 885 pairs of RL vs OL, 1,711 pairs of RL vs VATS, and 952 pairs of VATS vs OL. Operative time for RL was shorter than VATS ( P < 0.0001) and OL ( P = 0.0004). Compared to OL, RL and VATS had less overall postoperative complications, shorter hospital stay (LOS), and lower transfusion rates (all P <0.02). Compared to VATS, RL had lower conversion rate ( P <0.0001), shorter hospital stay ( P <0.0001) and a lower postoperative transfusion rate ( P =0.01). RL and VATS cohorts had comparable postoperative complication rates. In-hospital mortality was comparable between all groups. CONCLUSIONS: RL and VATS approaches were associated with favorable perioperative outcomes compared to OL. Robotic-assisted lobectomy was also associated with a reduced length of stay and decreased conversion rate when compared to VATS.

Variability in Excess Lobectomy Billing Among US Thoracic Surgeons.

BACKGROUND: Transparency in physician billing practices in the United States is lacking. Often, charges may vary substantially between providers and excess charges may be passed on to the patient. In this study, we evaluate Medicare charges and payments for minimally invasive lobectomy to obtain a sense of national billing practices and evaluate for predictors of higher charges. METHODS: The 2018 Medicare Provider Utilization Data was queried to identify surgeons submitting charges for Video-Assisted Thoracoscopic Lobectomy. Excess charges were determined by each provider. Additional demographic variables were collected including geographic region for general surgery and cardiothoracic surgery training, years in practice, and current practice setting. A multivariate gamma regression was utilized to determine predictors of high billing practices. RESULTS: A total of 307 unique providers submitted charges ranging from $1,104 to $25,128 with a median of $4,265. The average Medicare Payment amount ranged from $163 to $1,409, with a median of $1,056. Male surgeons were estimated to charge 1.3 times more than female surgeons, while those in an academic setting were estimated to charge 1.4 times more than private practice (p < 0.01). Surgeons practicing in the South or West were estimated to charge 0.76 and 0.81 times as much as those practicing in the Northeast (p < 0.01). CONCLUSIONS: Billing practices vary widely across the United States. Charges submitted to Medicare likely represent a provider's charges across all payers. In today's healthcare economy, it is important for patients to understand the true cost of care and for providers to be mindful of reasonable and appropriate charges.

Trends and factors affecting approach choice to pulmonary resection.

BACKGROUND: The development of an advanced robotic platform in 2014 led to increased adoption of minimally invasive (MI) approaches in thoracic surgery. Due to dataset reporting lag, a comprehensive assessment of trends in thoracic approaches has not been analyzed to date. METHODS: We queried the National Cancer Database (NCDB) for patients with Stage I-III who underwent lung resection from 2010 to 2018. Most published NCDB analyses on lung cancer using pre-2015 data. Overall treatment trends were analyzed, with geographic, institutional, and socioeconomic characteristics evaluated for approach. RESULTS: There were 162 335 lung resections, and 131 958 were anatomic. Robotic resection saw a steady increase through 2012 but plateaued in 2013-2014. From 2015 to 2018, another increase correlated with the release of a new platform. Video-assisted thoracoscopic surgery lung resection plateaued in 2014 and decreased in 2018. Open resection steadily decreased. Tumors requiring neoadjuvant radiation had an increase in MI approach with corresponding decreases in the open. On multivariable analysis, African-American race, low volume, Medicaid insurance, and nonacademic setting were associated with a lower likelihood of MI surgery. CONCLUSIONS: The open approach has decreased since 2010. More than 65% of anatomic resections are now performed in MI. As this trend will continue, it is important that all patients are afforded the opportunity of the least invasive approach.

Percutaneous Dilational Tracheostomy for Coronavirus Disease 2019 Patients Requiring Mechanical Ventilation.

OBJECTIVES: To assess the impact of percutaneous dilational tracheostomy in coronavirus disease 2019 patients requiring mechanical ventilation and the risk for healthcare providers. DESIGN: Prospective cohort study; patients were enrolled between March 11, and April 29, 2020. The date of final follow-up was July 30, 2020. We used a propensity score matching approach to compare outcomes. Study outcomes were formulated before data collection and analysis. SETTING: Critical care units at two large metropolitan hospitals in New York City. PATIENTS: Five-hundred forty-one patients with confirmed severe coronavirus disease 2019 respiratory failure requiring mechanical ventilation. INTERVENTIONS: Bedside percutaneous dilational tracheostomy with modified visualization and ventilation. MEASUREMENTS AND MAIN RESULTS: Required time for discontinuation off mechanical ventilation, total length of hospitalization, and overall patient survival. Of the 541 patients, 394 patients were eligible for a tracheostomy. One-hundred sixteen were early percutaneous dilational tracheostomies with median time of 9 days after initiation of mechanical ventilation (interquartile range, 7-12 d), whereas 89 were late percutaneous dilational tracheostomies with a median time of 19 days after initiation of mechanical ventilation (interquartile range, 16-24 d). Compared with patients with no tracheostomy, patients with an early percutaneous dilational tracheostomy had a higher probability of discontinuation from mechanical ventilation (absolute difference, 30%; p < 0.001; hazard ratio for successful discontinuation, 2.8; 95% CI, 1.34-5.84; p = 0.006) and a lower mortality (absolute difference, 34%, p < 0.001; hazard ratio for death, 0.11; 95% CI, 0.06-0.22; p < 0.001). Compared with patients with late percutaneous dilational tracheostomy, patients with early percutaneous dilational tracheostomy had higher discontinuation rates from mechanical ventilation (absolute difference 7%; p < 0.35; hazard ratio for successful discontinuation, 1.53; 95% CI, 1.01-2.3; p = 0.04) and had a shorter median duration of mechanical ventilation in survivors (absolute difference, -15 d; p < 0.001). None of the healthcare providers who performed all the percutaneous dilational tracheostomies procedures had clinical symptoms or any positive laboratory test for severe acute respiratory syndrome coronavirus 2 infection. CONCLUSIONS: In coronavirus disease 2019 patients on mechanical ventilation, an early modified percutaneous dilational tracheostomy was safe for patients and healthcare providers and associated with improved clinical outcomes.

Diagnosis and management of rare inferior vena cava leiomyosarcoma guided by a novel minimally invasive vascular biopsy technique.

Primary vascular tumors such as vascular leiomyosarcomas are rare, but exhibit markedly different characteristics than tumors that invade the vasculature from a secondary source. Establishing a diagnosis is essential in determining the appropriate treatment plan, but obtaining a histologic specimen may prove challenging and carry significant risks. Minimally invasive endovascular biopsy techniques can be pivotal in the diagnosis-and thus in the management-of vascular tumors. We present a case of a primary inferior vena cava leiomyosarcoma, not able to be adequately assessed by noninvasive imaging and deemed too risky to be approached with traditional percutaneous biopsy techniques. Accurate diagnosis of such tumors is critical, as the success of surgical resection, although high risk, depends greatly upon the type, location, and extent of malignancy.

Variation in Treatment Charges and Reimbursement Among Individual Thoracic Surgeons.

BACKGROUND: Health care use and costs have undergone an increase in public scrutiny. Other specialties have evaluated practice patterns of their most highly reimbursed surgeons and found unique billing and procedure overuse. In this study, we evaluate Medicare payments to general thoracic surgeons and evaluate those with the highest reimbursements. METHODS: The 2018 Medicare Provider Utilization Data were queried to identify thoracic surgeons. Services were grouped into common categories: Evaluation and Management, Lung/Pleura, Foregut, Chest Wall, Airway, Diaphragm, Mediastinum, Endoscopy, and Transplant. Payment data were analyzed for surgeons receiving the top 1% of Medicare payments and the remainder of the workforce. RESULTS: In 2018, 2000 unique self-identified thoracic surgeons received a total of $54,734,736 in payments from Medicare for thoracic-related services. The top 1% of thoracic surgeons (n = 20) received $4,607,561, or 8.4% of total payments. Inpatient Evaluation and Management was the leading payment category for the top 1% (48.5% of payments), whereas Outpatient Evaluation and Management led for the remaining workforce (43.5% of payments). Whereas the surgical procedure code with overall highest reimbursement for both groups was Current Procedural Terminology (American Medical Association) 32663 (video-assisted thoracic surgery lobectomy), there was a difference with an increased use of high relative value unit unbundled Current Procedural Terminology codes in the highest earners. CONCLUSIONS: A disproportionate amount of Medicare reimbursement went to top 1%. The highest earners appeared to earn the most from inpatient treatment codes and also used unbundled codes more often. Because billing code use is not regulated and often subjective, a deeper evaluation by the major surgical societies may be warranted.

Management of Congenital Hernias in Adults: Foramen of Morgagni Hernia.

Morgagni hernias may range from asymptomatic incidental findings to surgical emergencies. An abdominal approach is ideal in the majority of cases, although surgeons should understand alternatives for repair.

Surgical-decision making in the setting of unsuspected N2 disease: a cost-effectiveness analysis.

Background: Identification of unsuspected nodal metastasis may occur at the time of operation for a stage I non-small cell lung cancer. Guidelines for this scenario are unclear. Our goal was to assess the cost-effectiveness of aborting the operation in an attempt to first provide neoadjuvant systemic therapy compared with upfront resection. Methods: A computer simulation Markov model with a lifetime horizon was constructed to compare the costs and clinical outcomes, as measured by quality-adjusted life-years (QALYs), of upfront resection at the time of identification of unsuspected N2 mediastinal disease vs. aborting initial resection and continuing with neoadjuvant therapy prior to resection. Input parameters for the model were derived from published literature with costs measured from the healthcare perspective. The incremental cost-effectiveness ratio (ICER) was evaluated with a willingness-to-pay (WTP) threshold of $150,000/QALY. Both deterministic (one-, two-, and three-way) and probabilistic sensitivity analysis (PSA) were performed to assess the impact of variation in input parameter values on model results. Results: Aborting initial resection in favor of neoadjuvant therapy resulted in both higher costs ($40,415 vs. $29,873) and more QALYs (3.95 vs. 2.84) relative to upfront resection, yielding an ICER of $9,526/QALY. While variation in overall survival had a significant impact on the ICER, perioperative variables did not. As the annual mortality of best-case therapy in the abort group increased from a base-case estimate of 11% to 15%, the ICER exceeded the WTP threshold of $150,000/QALY. Subsequent one- and two-way sensitivity analyses did not find substantially alter the overall results. PSA resulted in aborting resection to be cost-effective in 99.7% of samples, with 13% of samples dominating upfront resection. Conclusions: Treatment of stage IIIa lung cancer requires the input of a multidisciplinary team who must consider cost, quality of life, and overall survival. As new treatments are developed, further analyses should be performed to determine optimal therapy.

Robotic Surgery in Thoracic Training Programs: A National Needs Assessment.

BACKGROUND: The cardiothoracic surgical trainees perceive a need for more instruction and exposure to robotic-assisted thoracoscopic surgery (RATS) during their training. We sought to assess utilization and trainee exposure to robotic surgery in thoracic residency programs to identify areas for improvement. METHODS: A voluntary electronic survey of 10 questions was distributed to surgeons working in all thoracic surgery residency programs in the United States. The survey asked to provide the size of the residency, the availability and utilization of robots, and the trainee's adoption of robotic surgery in their practice after graduation. Multivariable logistic regression was performed with Stata MP version 17.0 (College Station, TX). RESULTS: Of a total of 76 cardiothoracic surgery training programs, surgeons from 69 training programs completed the survey (90.8%). The majority of pulmonary lobectomy was performed using robotic surgery (55%). About half of the training programs (35/69) have a formal robotic curriculum for the residents. Of 121 thoracic-track trainees, 118 trainees (97.5%) performed robotic surgery as part of their practice, while 62 of 110 (56.4%) cardiothoracic (CT) track and 16 of 158 (10.1%) cardiac-track trainees performed robotic surgery. In a multivariate analysis, the adoption of robotic surgery was associated with having an established robotic training curriculum (OR 5.82, 95% CI 1.32 - 35.7), and a larger training program (OR 3.78, 95% CI 1.34 - 10.6). CONCLUSIONS: A disparity exists in robotic surgical training among the training programs. A standardized curriculum and formal case requirements may be needed to ensure optimal preparation for future graduates.

The Society of Thoracic Surgeons Expert Consensus Document on the Management of Pleural Drains After Pulmonary Lobectomy: Expert Consensus Document.

The Society of Thoracic Surgeons Workforce on Evidence-Based Surgery provides this document on management of pleural drains after pulmonary lobectomy. The goal of this consensus document is to provide guidance regarding pleural drains in 5 specific areas: (1) choice of drain, including size, type, and number; (2) management, including use of suction vs water seal and criteria for removal; (3) imaging recommendations, including the use of daily and postpull chest roentgenograms; (4) use of digital drainage systems; and (5) management of prolonged air leak. To formulate the consensus statements, a task force of 15 general thoracic surgeons was invited to review the existing literature on this topic. Consensus was obtained using a modified Delphi method consisting of 2 rounds of voting until 75% agreement on the statements was reached. A total of 13 consensus statements are provided to encourage standardization and stimulate additional research in this important area.

Resident Training in Robotic Thoracic Surgery.

The use of a robotic surgical platform has become common place in thoracic surgery programs throughout the United States. Formal training paradigms need to be reevaluated to allow for effective and efficient training of thoracic surgery residents and fellows. The utilization of video-based coaching and simulation are effective adjuncts in robotics training.

National guideline concordance and outcomes for pathologic N2 disease in non-small cell lung cancer.

Background: Real-world treatment practices for positive mediastinal nodal disease in non-small cell lung cancer (NSCLC) continues to vary despite guidelines. We aim to assess national trends in the treatment of pathologic-N2 disease, and evaluate the association with clinical nodal staging and timing of systemic therapy. Methods: The National Cancer Database was queried for patients with NSCLC who underwent lobectomy and had pathologic-N2 disease from 2010-2017. National Comprehensive Cancer Network (NCCN) guideline concordance was evaluated. cN2 patients were analyzed based on timing of systemic therapy and response. Multivariable logistic regression evaluated outcomes by type of systemic therapy. Survival analysis utilized Cox proportional hazards regression and Kaplan-Meier methods. Results: 10,225 patients met inclusion criteria. Fifty-four percent of patients were understaged prior to surgery as either cN0 or cN1. Of clinically staged N2 patients, 56% received NCCN recommended neoadjuvant therapy. Annual guideline concordance increased until 2016 to a max of 62.9%. Neoadjuvant and adjuvant systemic therapy showed an overall survival benefit compared with no systemic therapy (HR 0.54 & 0.57), but no difference when compared against each other. Complete response after neoadjuvant therapy was associated with improved survival (5-year OS 56.1%, P<0.001), while partial response, no-response, and adjuvant therapy were similar. All systemic treatment strategies improved survival compared with no systemic therapy (5-year OS 24.5%). Conclusions: Guideline concordance for treatment of cN2 disease has been increasing, but still not followed in over 1/3 of patients. Responsiveness to neoadjuvant therapy appears to be a predictor of survival, and may become a prognostic adjunct for determining which patients would benefit from additional systemic therapy.

Robotic Repair of Adult Left-Sided Partial Anomalous Pulmonary Venous Connection.

Isolated anomalous drainage of the left pulmonary vein to the left innominate vein is a rare variant of partial anomalous pulmonary venous connection. Here, we describe 2 adult patients with this variant who underwent successful robotic totally endoscopic repair with anastomosis of the pulmonary vein to the left atrial appendage.

Robotic totally endoscopic beating-heart bypass to the right coronary artery: first worldwide experience.

OBJECTIVES: Left coronary vessels are the usual targets in totally endoscopic coronary artery bypass (TECAB). Grafting of the right coronary artery (RCA) has been limited using this approach because of anatomic and technical difficulties. We report a first series of robotic beating-heart TECAB to the RCA via a right-chest approach. METHODS: From July 2013 to April 2019, patients who underwent robotic beating-heart TECAB with the right internal mammary artery to the RCA were reviewed. Port placement in the right chest mirrored standard left-sided ports. Indications for right internal mammary artery to RCA bypass were RCA disease not amenable to percutaneous intervention and anomalous origin of the RCA. RESULTS: Right internal mammary artery-RCA bypass was performed in 16 patients (mean age 60.6 ± 13.5, 75% male). All cases were completed without conversion to sternotomy or mini-thoracotomy. Cardiopulmonary bypass was required in 1 patient to expose the posterior descending artery. Mean procedure time was 223 ± 49 min, with half of the patients extubated in the operating room (50%). Mean intraoperative transit-time graft flow was 87.0 ± 19.3 ml/min, and a pulsatility index of 1.2 ± 0.2. Mean length of stay was 2.3 ± 1.2 days. No mortality was observed at mean follow-up time of 20.6 months. One patient required repeat RCA revascularization for progression of native disease 43.7 months after the surgery. CONCLUSIONS: Robotic beating-heart TECAB for isolated RCA disease is a feasible operation in selected patients. This technique is possible even for the posterior descending artery.

Outpatient Thoracoscopic Mediastinal Biopsy: A Safe and Cost-Effective Approach.

BACKGROUND: Most mediastinal biopsy patients are managed with an overnight inpatient stay and chest drainage. We sought to determine the safety, accuracy, and cost of outpatient thoracoscopic mediastinal biopsy by reviewing operative techniques, perioperative outcomes, and admission charges for this procedure. METHODS: This single-institution retrospective study reviewed all patients who underwent elective thoracoscopic mediastinal biopsy between 2012 and 2017. Patients were assigned to outpatient or inpatient management preoperatively based on surgeon judgment and preference. The procedures were performed in the supine or lateral decubitus position using ports only. Patients discharged on postoperative day 0 (outpatient) were compared with those discharged on postoperative day 1 or greater (inpatient). RESULTS: A total of 46 patients were included. Thirty-one patients were outpatients, and 15 were admitted. The outpatient cohort was younger than the inpatient group (48 years of age vs 66 years of age; P = .001). There was no statistically significant difference in other baseline characteristics. The operative time was longer (P = .001) and the total charges were higher (P = .003) in the inpatient cohort. One patient in each group had a nondiagnostic procedure. One patient in the outpatient group returned to the emergency department for pain but was discharged. There were no complications. CONCLUSIONS: Outpatient thoracoscopic mediastinal biopsy is a safe and effective procedure that has lower charges compared with inpatient management and should be considered for patients undergoing this procedure.

A Morphomic Index Is an Independent Predictor of Survival After Lung Cancer Resection.

BACKGROUND: Sarcopenia, visceral fat volume, and bone density have been associated with lung cancer survival. We developed a morphomic index based on computed tomographic measurements of these components, and assessed its relationship to survival after lung cancer resection. METHODS: Patients who underwent lung cancer resection from 1995 to 2014 were evaluated. A morphomic index (range of 0 to 3) was developed as the sum of the scores for three body components-dorsal muscle area, vertebral trabecular bone density, and visceral fat area-measured at vertebral levels T10 to T12, with a point assigned to each component when in the lowest tercile. The relationship of the morphomic index to overall survival was assessed by the log rank test. Overall survival was assessed using Cox proportional hazards models adjusted for relevant covariates. RESULTS: We included 944 patients (451 women; 48%). The mean age was 66.4 ± 10.3 years. Median follow-up was 4.5 years. Median survival was associated with the morphomic index scores on univariate analysis (P < .001). Morphomic index scores of 2 (P = .026) and 3 (P = .004) referenced to score 0 or 1 were independent predictors of survival on Cox regression analysis. CONCLUSIONS: A morphomic index is an independent predictor of survival after lung cancer resection. The index may help in calibrating patient expectations and in shared decision making regarding lung cancer surgery.

Bullet embolization to the heart: A rare and confounding penetrating cardiac injury case report.

Gunshot wounds to the cardiac region usually result in devastating injuries. However, if bullets embolize into the myocardium without significant damage to the organ, optimal evaluation and management remains unclear. We present the case of a hemodynamically stable gunshot wound patient who presented with a bullet to the heart. Sternotomy revealed that the bullet had embolized through the superior vena cava and embedded into the apex of the right ventricle. The patient was managed without retrieval of the bullet and continues to be well despite a retained intracardiac bullet. We discuss cases of bullet embolization to the heart and the emergence of minimally-invasive approaches for management.

Robotic Sleeve Resection of the Airway: Outcomes and Technical Conduct Using Video Vignettes.

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.
