Discharging Patients by Postoperative Day One After Robotic Anatomic Pulmonary Resection
Geraci, Travis C; Chang, Stephanie H; Chen, Stacey; Ferrari-Light, Dana; Cerfolio, Robert J
BACKGROUND:Our objective is to assess the feasibility and safety of discharging patients by postoperative day one (POD1) after robotic segmentectomy and lobectomy, and to describe outcomes for patients. METHODS:A retrospective analysis was made 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, of 253 patients who underwent robotic anatomic pulmonary resection, 134 (53%) were discharged by POD1, 67% after segmentectomy and 41% after lobectomy. Discharge by POD1 improved with experience and was achieved in 97% of patients after segmentectomy and 68% after lobectomy in the final quartile. Thirty-one patients (12%) 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 minor morbidities (4%), 6 major morbidities (2.4%), and no 30- or 90-day mortality. There were 4 readmissions (1.6%), of which 1 (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.

Beyond the learning curve: a review of complex cases in robotic thoracic surgery
Geraci, Travis C; Scheinerman, Joshua; Chen, David; Kent, Amie; Bizekis, Costas; Cerfolio, Robert J; Zervos, Michael D
The number of thoracic surgery cases performed on the robotic platform has increased steadily over the last two decades. An increasing number of surgeons are training on the robotic system, which like any new technique or technology, has a progressive learning curve. Central to establishing a successful robotic program is the development of a dedicated thoracic robotic team that involves anesthesiologists, nurses, and bed-side assistants. With an additional surgeon console, the robot is an excellent platform for teaching. Compared to current methods of video-assisted thoracoscopic surgery (VATS), the robot offers improved wristed motion, a magnified, high definition three-dimensional vision, and greater surgeon control of the operation. These advantages are paired with integrated adjunctive technology such as infrared imaging. For pulmonary resection, these advantages of the robotic platform have translated into several clinical benefits, such as fewer overall complications, reduced pain, shorter length of stay, better postoperative pulmonary function, lower operative blood loss, and a lower 30-day mortality rate compared to open thoracotomy. With increased experience, cases of greater complexity are being performed. This review article details the process of becoming an experienced robotic thoracic surgeon and discusses a series of challenging cases in robotic thoracic surgery that a surgeon may encounter "beyond the learning curve". Nearly all thoracic surgery can now be approached robotically, including sleeve lobectomy, pneumonectomy, resection of large pulmonary and mediastinal masses, decortication, thoracic duct ligation, rib resection, and pulmonary resection after prior chest surgery and/or chemoradiation.

Technique, Outcomes with Navigational Bronchoscopy Using Indocyanine Green for Robotic Segmentectomy
Geraci, Travis C; Ferrari-Light, Dana; Kent, Amie; Michaud, Gaetane; Zervos, Michael; Pass, Harvey; Cerfolio, Robert J
BACKGROUND:Our objectives are to present our outcomes of robotic segmentectomy and our preferred technique for nodule localization using indocyanine green both bronchoscopically and intravenously. METHODS:This is 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 which 93 (38%) received indocyanine green via 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%). Our preferred technique is: 0.5 mL of 25 mg of indocyanine green diluted in 10 mL of saline 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 is 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 1-21 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 our series, electromagnetic navigational bronchoscopy and indocyanine green localization is efficient and effective at identifying the target lesion. Intravenous indocyanine green delineates the intersegmental plane.

Graft Survival in Single versus Bilateral Lung Transplantation for Emphysema
Stewart, Darren E; Ruck, Jessica M; Massie, Allan B; Segev, Dorry L; Lesko, Melissa B; Chan, Justin C; Chang, Stephanie H; Geraci, Travis C; Rudym, Darya; Sonnick, Mark A; Barmaimon, Guido; Angel, Luis F; Natalini, Jake G
The benefits of bilateral lung transplantation (BLT) versus single lung transplantation (SLT) are still debated. One impediment to clinical recommendations is that BLT vs. SLT advantages may vary based on underlying disease. Since both options are clinically tenable in patients with emphysema, we conducted a comprehensive assessment of lung allograft survival in this population. Using U.S. registry data, we studied time to all-cause allograft failure in 8,092 patients 12 years or older transplanted from 2006 to 2022, adjusting for recipient, donor, and transplant factors by inverse propensity weighting. Median allograft survival was 6.6 years in BLT compared to 5.3 years in SLT, a 25% risk-adjusted survival advantage of 0.81.31.8 years. Risk-adjusted bilateral survival advantages varied between 0.9 and 2.4 years across eleven subgroups. Median allograft survival in BLT was 1.2 years greater than right SLT and 2.0 years greater than left SLT. During the 16-year study period, allograft survival steadily improved for BLT but not for SLT. Although the 25% BLT survival advantage pre-dated the pandemic, COVID-19 may have contributed to an apparent SLT survival decline. Recognizing the possible influence of residual confounding due to selection biases, these findings may aid offer decision-making when both donor lungs are available.

Post Lung Transplant Primary Graft Dysfunction
Geraci, Travis C; Chan, Justin Cy; Niroomand, Anna; Chang, Stephanie H
Primary graft dysfunction (PGD) is a major source of morbidity and mortality following lung transplantation, presenting as acute lung injury within 72 hours post-transplantation. Despite advances in surgical techniques and perioperative care, the complex interplay of donor, recipient, and perioperative factors contributes to its development, underscoring the multifactorial nature of PGD. Clinical management of recipients with PGD relies on supportive care strategies, including lung-protective ventilation, inhaled nitric oxide, and extracorporeal membrane oxygenation (ECMO). Severe cases of PGD may result in significant short- and long-term adverse outcomes, including early mortality. Even for patients who recover from PGD, there is also an associated increased risk of chronic lung allograft dysfunction, further compounding its clinical impact. This review provides a brief review of current knowledge regarding PGD, detailing risk factors, diagnostic criteria, and management approaches while identifying critical gaps in understanding its pathophysiology. Ongoing research is essential to develop innovative therapeutic strategies and improve outcomes for lung transplant recipients.

RATIONALE/BACKGROUND:Lower airway enrichment with oral commensals has been previously associated with grade 3 severe primary graft dysfunction (PGD) after lung transplantation (LT). We aimed to determine whether this dysbiotic signature is present across all PGD severity grades, including milder forms, and whether it is associated with a distinct host inflammatory endotype. METHODS:Lower airway samples from 96 LT recipients with varying degrees of PGD were used to evaluate the lung allograft microbiota via 16S rRNA gene sequencing. Bronchoalveolar lavage (BAL) cytokine concentrations and cell differential percentages were compared across PGD grades. In a subset of samples, we evaluated the lower airway host transcriptome using RNA sequencing methods. RESULTS:Differential analyses demonstrated lower airway enrichment with supraglottic-predominant taxa (SPT) in both moderate and severe PGD. Dirichlet Multinomial Mixtures (DMM) modeling identified two distinct microbial clusters. A greater percentage of subjects with moderate-severe PGD were identified within the dysbiotic cluster (C-SPT) than within the no PGD group (48 and 29%, respectively) though this difference did not reach statistical significance (p=0.06). PGD severity associated with increased BAL neutrophil concentration (p=0.03) and correlated with BAL concentrations of MCP-1/CCL2, IP-10/CXCL10, IL-10, and TNF-α (p<0.05). Furthermore, microbial signatures of dysbiosis correlated with neutrophils, MCP-1/CCL-2, IL-10, and TNF-α (p<0.05). C-SPT exhibited differential expression of TNF, SERPINE1 (PAI-1), MPO, and MMP1 genes and upregulation of MAPK pathways, suggesting that dysbiosis regulates host signaling to promote neutrophilic inflammation. CONCLUSIONS:Lower airway dysbiosis within the lung allograft is associated with a neutrophilic inflammatory endotype, an immune profile commonly recognized as the hallmark for PGD pathogenesis. This data highlights a putative role for lower airway microbial dysbiosis in the pathogenesis of this syndrome.

Dorsey, Michael; Phillips, Katherine; James, Les; Kelley, Emily; Duff, Erica; Lewis, Tyler; Merchan, Cristian; Menghani, Neil; Chan, Justin; Chang, Stephanie; Geraci, Travis; Moazami, Nader; Smith, Deane
OBJECTIVE/UNASSIGNED:Anticoagulation monitoring in patients supported on extracorporeal membrane oxygenation is challenging given the risks of both bleeding and thrombotic complications. Based on our early clinical experience, we revised our heparin protocol by reducing our target anti-factor Xa assay from 0.3 to 0.7 U/mL to 0.15 to 0.5 U/mL, while instituting a partial thromboplastin time cutoff of 70 seconds. We evaluated the impact of this change on bleeding/thrombotic complications. METHODS/UNASSIGNED:A single-center retrospective study of adult patients on extracorporeal membrane oxygenation support was conducted from January 2015 to August 2022. Patients were stratified into groups based on protocol revision: Pre-Revision (2015-2018) or Post-Revision (2019-2022). Our primary end point was the incidence of bleeding/thrombotic complications. Time in therapeutic range was calculated to determine protocol adherence. Poisson regression was performed to correlate time in therapeutic range with the likelihood of complication. RESULTS/UNASSIGNED:008). CONCLUSIONS/UNASSIGNED:A modified heparin monitoring protocol defined by a lower therapeutic anti-factor Xa assay target and a set partial thromboplastin time cutoff correlated with decreases in bleeding/thrombotic complications in patients on extracorporeal membrane oxygenation.

Discharging Patients Home with a Chest Tube and Digital System after Robotic Lung Resection
Geraci, Travis C; McCormack, Ashley J; Cerfolio, Robert J
BACKGROUND:Our objective is to assess the feasibility, safety, and outcomes for patients discharged home with a chest tube connected to a digital drainage system after robotic pulmonary resection. METHODS:A retrospective analysis of a prospectively collected database as a quality improvement initiative. All patients had planned discharge on postoperative day one (POD1) after robotic pulmonary resection. Those with an air leak were discharge home with a chest tube connected to a digital drainage system with daily communication with the surgeon. RESULTS:From January 2019 to February 2023 there were 580 consecutive robotic resections, of which 69 (12%) patients had an air leak on POD1; 38/276 (14%) after lobectomy, 24/226 (11%) after segmentectomy, and 7/78 (9%) after wedge resection. Of these 69 patients, 52 patients (75%) were discharged on POD1, 15 patients (22%) on POD2, and 2 patients (3%) on POD3. Chest tubes were removed a median outpatient chest tube duration was 4 days (IQR 3-5). Of the 69 patients sent home with a digital drainage system, there was one complication requiring readmission for increasing subcutaneous emphysema. Five patients (7%) had system malfunctions that required return to our clinic for problem solving. There were no 30 or 90-day mortalities. CONCLUSIONS:Patients who undergo robotic pulmonary resection and have an air leak can be safely and effectively discharged on the first post-operative day and managed as an outpatient by using daily texts and or videos with pulse oximetry data on a digital drainage system with limited morbidity.
