The essential role of non-steroidal anti-inflammatory drugs in pain control following robotic thoracoscopic lung resections.

Background: Enhanced recovery after thoracic surgery (ERATS) protocols use a combination of analgesics for pain control. We investigated the effect of non-steroidal analgesic drugs (NSAIDs) on pain control by comparing patient levels and opioid requirements after robotic pulmonary resections. Methods: We retrospectively analyzed our prospectively maintained institutional database for elective, opioid-naïve robotic thoracoscopic pulmonary resections. All patients received postoperative NSAIDs unless contraindicated or at the discretion of the attending surgeons. Our original protocol (ERATS-V1) was modified to optimize opioid-sparing effect without affecting pain control (ERATS-V2). Demographics, operative outcomes, and postoperative opioid dispensed [morphine milligram equivalent (MME)] were collected. Results: A total of 491 patients (147 ERATS-V1; 344 ERATS-V2) were included in this study. There was no difference in patient characteristics or operative outcomes between ERATS cohorts. Protocol optimization was associated with a 2- to 10-fold reduction of postoperative opioid use without compromising pain control. In ERATS-V1 cohort, there was no difference in pain levels and opioid requirements with NSAID usage. In ERATS-V2 cohort, while pain levels were similar, higher in-hospital opioid consumption was observed in no-NSAID subgroup {MME: 20.5 [interquartile range (IQR), 4.8-40.5] vs. 12.0 (IQR, 2.0-32.2), P=0.0096, schedule II: 14.2 (IQR, 3.0-36.4) vs. 6.8 (IQR, 1.4-24.0), P=0.012} as well as total postoperative schedule II opioid requirement [17.8 (IQR, 3.0-43.5) vs. 8.8 (IQR, 1.5-30), P=0.032]. Conclusions: The opioid-sparing effect of NSAIDs was observed only in optimized ERATS patients. Modifications of our pre-existing ERATS was associated with a significant reduction of opioid consumption without affecting pain levels. This revealed the role of NSAIDs in postoperative pain management otherwise masked by excessive opioids use.

Extracorporeal membrane oxygenation in the surgical management of large mediastinal masses: a narrative review.

Background and Objective: The management of large mediastinal tumors requires a complex multidisciplinary approach, particularly in the perioperative setting due to increased risk of hemodynamic compromise. The utilization of extracorporeal membrane oxygenation (ECMO) provides a useful adjunct in the surgical management for biopsy and resection of these mediastinal masses. The objective of this article is to review indications and implementation of ECMO in the surgical management of mediastinal disease. Methods: A literature review of the PubMed database was completed evaluating articles discussing 'extracorporeal circulation', 'cardiopulmonary bypass', 'anesthesia', 'mediastinal disease', and 'mediastinal cancer'. These articles were evaluated for contribution to the discussion of indications and implementation of ECMO in the management of these patients. Key Content and Findings: Large mediastinal tumors place patients at risk of hemodynamic collapse on induction of anesthesia due to compression of vascular structures, tracheobronchial tree and creation of V/Q mismatch. Patients may be stratified regarding their risk of perioperative complications by evaluation of postural symptoms, cross sectional imaging findings and pulmonary function tests. Those patients at elevated perioperative risk may benefit from the utilization of ECMO, most commonly veno-arterial (V-A) ECMO. Guidewires or ECMO cannulas may be placed under local anesthesia prior to induction. Those patients with hemodynamic compromise may receive mechanical circulatory support to allow completion of the operation. Conclusions: The use of a multidisciplinary team consisting of surgeons, anesthesiologists, perfusionists and OR team is critical to the success in the use of ECMO in the resection of mediastinal masses. With diligent preparation, these high-risk patients may be optimally managed at the time of resection.

Achieving opioid-free discharge following robotic thoracic surgery: A single-institution experience.

Objectives: Enhanced recovery after thoracic surgery (ERATS) protocols use a combination of analgesics for pain control and have been associated with decreased opioid requirements. We investigated the impact of continual ERATS refinement on the incidence of opioid-free discharge. Methods: We retrospectively analyzed our prospectively maintained institutional database for elective, opioid-naive robotic thoracoscopic procedures. Demographics, operative outcomes, postoperative opioid dispensed (morphine milligram equivalent), and opioid discharge status were collected. Our primary outcome of interest was factors associated with opioid-free discharge; our secondary objective was to determine the incidence of new persistent opioid users. Results: In total, 466 patients from our optimized ERATS protocol were included; 309 (66%) were discharged without opioids. However, 34 (11%) of patients discharged without opioids required a prescription postdischarge. Conversely, 7 of 157 patients (11%), never filled their opioid prescriptions given at discharge. Factors associated with opioid-free discharges were nonanatomic resections, mediastinal procedures, minimal pain, and lack of opioid usage on the day of discharge. More importantly, 3.2% of opioid-free discharge patients became new persistent opioid users versus 10.8% of patients filling opioid prescriptions after discharges (P = .0013). Finally, only 2.3% of opioid-naive patients of the entire cohort became chronic opioid users; there was no difference in the incidence of chronic use by opioid discharge status. Conclusions: Optimized opioid-sparing ERATS protocols are highly effective in reducing opioid prescription on the day of discharge. We observed a very low rate of new persistent or chronic opioid use in our cohort, further highlighting the role ERATS protocols in combating the opioid epidemic.

French-speaking Swiss physician's perceptions and perspectives regarding their competencies and training need in leadership and management: a mixed-methods study.

INTRODUCTION: Effective leadership and management (L&M) are essential to the success of health care organizations. Young medical leaders often find themselves ill-prepared to take on these new responsibilities, but rarely attend training in L&M skills. The aims of this study were to evaluate physician's self-perceived competencies and training needs for L&M, to identify available regional L&M training, and to highlight opportunities, challenges and threats regarding physicians' training in medical L&M in the French-speaking part of Switzerland. METHODS: We conducted a mixed methods study in three steps: (1) a survey on perceived L&M competencies and training needs (5 dimensions) to all physicians of a Swiss University Hospital (N = 2247); (2) a mapping of the Swiss French speaking L&M training programs through analysis of hospital websites and interviews; and (3) semi-structured interviews with L&M program coordinators about the programs' strengths and weaknesses as well as the opportunities and challenges to include physicians in such training. We used analysis of variance to compare differences in perceived competences between physicians of different hierarchical status and used Cramer's V to measure the association's degree between physicians' training needs and prior training in L&M and hierarchical status. We analysed semi-structured interviews using thematic analysis. RESULTS: Five-hundred thirty-two physicians responded (24%). Physicians perceived themselves as rather competent in most leadership dimensions. More experienced physicians reported a higher sense of competence in all dimensions of leadership (e.g. Working with others: F = 15.55, p < .001; Managing services: F = 46.89, p < .001). Three competencies did not vary according to the hierarchical status: emotional intelligence (F = 1.56, p = .20), time management (F = 0.47, p = .70) and communicating (F = 1.97, p = .12). There was a weak to moderate association between the responders' self-perceived needs for training and their hierarchal status for all competencies (Cramer's V ∈ [0.16;0.35]). Physicians expressed a strong desire to seek out training for all competencies, especially for knowing one's leadership style (82%), managing teams (83%), and managing conflict (85%). Although existing local L&M training programs covered most relevant topics, only a forth of responders had attended any type of training. L&M program coordinators identified several facilitators and barriers to physician attendance on institutional (matching reality and training), relational (managing collective intelligence), and individual levels (beliefs and self-perceived identity). CONCLUSIONS: French-speaking Swiss hospital physicians clearly express training needs for L&M skills although they only rarely attend such training programs. Reasons for non-attendance to such programs should be explored in order to understand physicians' low participation rates in these trainings.

Bronchogenic cysts: a narrative review.

Background and Objective: Bronchogenic cysts represent a rare form of cystic malformation of the respiratory tract. Primarily located in the mediastinum if occurring early in gestation as opposed to the thoracic cavity if arising later in development. However, they can arise from any site along the foregut. They exhibit a variety of clinical and radiologic presentations, representing a diagnostic challenge, especially in areas with endemic hydatid disease. Endoscopic drainage has emerged as a diagnostic and potentially therapeutic option but has been complicated by reports of infection. Surgical excision remains the standard of care allowing for symptomatic resolution and definitive diagnosis via pathologic examination; minimally invasive approaches such as robotic and thoracoscopic approaches aiding treatment. Following complete resection, prognosis is excellent with essentially no recurrence. Methods: A review of the available electronic literature was performed from 1975 through 2022, using PubMed and Google Scholar, with an emphasis on more recent series. We included all retrospective series and case reports. A single author identified the studies, and all authors reviewed the selection until there was a consensus on which studies to include. Key Content and Findings: The literature consisted of relatively small series, mixed between adult and pediatric patients, and the consensus remains that all symptomatic lesions should be excised via minimally invasive approach where feasible. Conclusions: Surgical excision of symptomatic bronchogenic cysts remains the gold standard, with endoscopic drainage being reserved for diagnosis or as a temporizing measure in clinically unstable patients.

Association between burnout and stigma in physicians.

BACKGROUND: Physicians suffering from burnout are more likely to develop depression, substance dependence, and cardiovascular diseases, which can affect their practices. Stigmatization is a barrier to seeking treatment. This study aimed to understand the complex links between burnout among medical doctors and the perceived stigma. METHODS AND FINDINGS: Online questionnaires were sent to medical doctors working in five different departments of the Geneva University Hospital. The Maslach Burnout Inventory (MBI) was used to assess burnout. The Stigma of Occupational Stress Scale in Doctors (SOSS-D) was used to measure the three stigma dimensions. Three hundred and eight physicians participated in the survey (response rate: 34%). Physicians with burnout (47%) were more likely to hold stigmatized views. Emotional exhaustion was moderately correlated with perceived structural stigma (r = 0.37, P < .001) and weakly correlated with perceived stigma (r = 0.25, P = 0.011). Depersonalization was weakly correlated with personal stigma (r = 0.23, P = 0.04) and perceived other stigma (r = 0.25, P = 0.018). CONCLUSION: These results suggest the need to adjust for existing burnout and stigma management. Further research needs to be conducted on how high burnout and stigmatization impact collective burnout, stigmatization, and treatment delay.

Disparities in Survival Due to Social Determinants of Health and Access to Treatment in US Patients With Operable Malignant Pleural Mesothelioma.

Importance: Outcomes of localized malignant pleural mesothelioma (MPM) remain poor despite multimodality therapy. It is unclear what role disparities have in the overall survival (OS) of patients with operable MPM. Objective: To examine survival disparities associated with social determinants of health (SDOHs) and treatment access in patients with malignant pleural mesothelioma. Design, Setting, and Participants: In this observational, retrospective cohort study, patients with MPM diagnosed between January 1, 2004, and December 31, 2017, were identified from the National Cancer Database with a maximum follow-up time of 13.6 years. The analysis was conducted from February 16, 2022, to July 29, 2022. Patients were included if they were diagnosed with potentially resectable clinical stage I to IIIA MPM, had epithelioid and biphasic histologic subtypes, and received chemotherapy. Patients were excluded if they could not receive curative surgery, were 75 years or older, or had metastasis, unknown stage, or tumor extension to the chest wall, mediastinal tissues, or organs. Exposures: Chemotherapy alone vs chemotherapy with curative surgery in the form of pleurectomy and decortication or extrapleural pneumonectomy. Main Outcomes and Measures: The primary end point was OS. Cox proportional hazards regression models were used to determine hazard ratios (HRs) for OS, including univariable and multivariable models controlling for potential confounders, including demographic, comorbidity, clinical, treatment, tumor, and hospital-related variables, as well as SDOHs. Results: A total of 1389 patients with MPM were identified (median [IQR] age, 66 [61-70] years; 1024 [74%] male; 12 [1%] Asian, 49 [3%] Black, 74 [5%] Hispanic, 1233 [89%] White, and 21 [2%] of other race). The median OS was 1.7 years (95% CI, 1.6-1.8). Risk factors associated with worse OS included older age, male sex, Black race, low income, and low educational attainment. Factors associated with greater odds of survival included receipt of surgical therapy, recent year of treatment, increased distance to travel, and treatment at high-volume academic hospitals. The risk factors most strongly associated with poor OS included Black race (HR, 1.96; 95% CI, 1.43-2.69) and male sex (HR, 1.60; 95% CI, 1.38-1.86). Surgical treatment in addition to systemic chemotherapy (HR, 0.70; 95% CI, 0.61-0.81) was independently associated with improved OS, as were chemotherapy initiation (HR, 0.93; 95% CI, 0.87-0.99) and greater travel distance from the hospital (HR, 0.92; 95% CI, 0.86-0.98). Conclusions and Relevance: In this retrospective cohort study of patients with operable MPM, there was significant variability in access to care by SDOHs. Addressing disparities in access to multimodality therapy can help ensure equity of care for patients with MPM.

The impact of social determinants of health on textbook oncological outcomes and overall survival in locally advanced non-small cell lung cancer.

Objectives: Textbook oncological outcome (TOO) is a composite metric for surgical outcomes, including non-small cell lung cancer (NSCLC). We hypothesized that social determinants of health (SDH) can affect both the attainment of TOO and the overall survival (OS) in surgically resected NSCLC patients with pathological nodal disease. Methods: We queried the National Cancer Database (2010-2017) for preoperative therapy-naïve lobectomies for NSCLC with tumor size <7 cm and pathologic N1/N2. Socioeconomic factors comprised SDH scores, where SDH negative (-) was considered if SDH ≥2 (disadvantage); otherwise, SDH was positive (+). TOO+ was defined as R0 resection, ≥5 lymph nodes resected, hospital stay <75th percentile, no 30-day mortality, adjuvant chemotherapy initiation ≤3 months, and no unplanned readmission. If one of these parameters was not achieved, the case was considered TOO-. Results: Of 11,274 patients, 48% of cases were TOO+ and 38% were SDH+. A total of 15% of patients were SDH- and were less likely (adjusted odds ratio, 0.85; 95% confidence interval [CI], 0.78-0.92) to achieve TOO+ than patients with SDH+. After accounting for confounders, patients with TOO+ had 22% lower overall mortality than patients with TOO- (adjusted hazard ratio, 0.78; CI, 0.73-0.82). In contrast, SDH- remained an independently significant risk factor, reducing survival by 24% compared with SDH+ (adjusted hazard ratio, 1.24; CI, 1.17-1.32). The impact of SDH on OS was significant for both patients with TOO+ and TOO-: SDH+/TOO+ had the best OS and SDH-/TOO-had the worst OS. Conclusions: SDH score has a significant association with TOO achievement and TOO-driven overall posttreatment survival in patients with lobectomy-resected NSCLC with postoperative pathologic N1/N2 nodal metastasis. Addressing SDH is important to optimize care and long-term survival of this patient population.

Postoperative day 1 discharge following robotic thoracoscopic pulmonary anatomic resections in the era of enhanced recovery protocol: A single-institution experience.

Objective: Implementation and continuing optimization of enhanced recovery protocol after thoracic surgery results in significant improvement of postoperative outcomes. We observed a 10-fold increase in the rate of postoperative day (POD) 1 discharges following robotic thoracoscopic anatomic resections over time. We aimed to determine factors associated with safe POD1 discharges. Methods: We performed a retrospective analysis of a prospectively maintained database of robotic anatomic pulmonary resections between July 1, 2012, and June 30, 2022, with patients of the last 2.5 years forming the basis of this study. Data collected included demographics, insurance types, Area Deprivation Index (indicator of poverty), and operative and postoperative variables including length of stay, opioid use, daily pain levels, readmissions, and outpatient interventions. Factors associated with POD1 were analyzed using a logistic regression module. Result: In total, 279 patients met inclusion criteria (91 POD1 discharges, 32.6%; none discharged with a pleural catheter). There was neither an increase of postdischarge interventions for pleural complications nor readmission in early discharge patients. After adjusting for relevant factors, younger age, right middle lobectomy, lower opioid use on POD1, operating room finish before 4 PM, and low Area Deprivation Index were significantly associated with POD1 discharge. A subanalysis of 49 patients, who could have been discharged on POD1, identified hypoxemia requiring home oxygen, atrial fibrillation, and poorly controlled pain being common mitigatable clinical factors delaying POD1 discharge. Conclusions: Safe POD1 discharge following robotic thoracoscopic anatomic resection was achieved in 32% of cases. Identification of positive and negative factors affecting early discharge provides guidance for further modifications to increase the number of POD1 discharges.

Optimization of an Enhanced Recovery After Surgery protocol for opioid-free pain management following robotic thoracic surgery.

Objectives: Our Enhanced Recovery After Thoracic Surgery protocol was implemented on February 1, 2018, and firmly established 7 months later. We instituted protocol modifications on January 1, 2020, aiming to further reduce postoperative opioid consumption. We sought to evaluate the influence of such efforts on clinical outcomes and the use of both schedule II and schedule IV opioids following robotic thoracoscopic procedures. Methods: A retrospective study of patients undergoing elective robotic procedures between September 1, 2018, and December 31, 2020, was conducted. Essential components of pain management in the original protocol included nonopioid analgesics, intercostal nerve blocks with long-acting liposomal bupivacaine diluted with normal saline, and opioids (ie, scheduled tramadol administration and as-needed schedule II narcotics). Protocol optimization included replacing saline diluent with 0.25% bupivacaine and switching tramadol to as needed, keeping other aspects unchanged. Demographic characteristics, type of robotic procedures, postoperative outcomes, and in-hospital and postdischarge opioids prescribed (ie, milligrams of morphine equivalent [MME]) were extracted from electronic medical records. Results: Three hundred twenty-four patients met the inclusion criteria (159 in the original and 183 in the optimized protocol). There was no difference in postoperative outcomes or acute postoperative pain; there was a significant reduction of in-hospital and postdischarge opioid requirements in the optimized cohort. For anatomic resections: mean, 60.0 MME (range, 0-60.0 MME) versus mean, 105.0 MME (range, 60.0-150.0 MME), and other procedures: mean, 0 MME (range, 0-60 MME) versus mean, 140.0 (range, 60.0-150.0 MME) (P < .00001) with median schedule II opioids prescribed = 0. Conclusions: Small modifications to our protocol for pain management strategies are safe and associated with significant decrease of opioid requirements, particularly schedule II narcotics, during the postoperative period without influencing acute pain levels.

Depth of mediastinal extension can predict sternotomy need for substernal thyroid goiters.

BACKGROUND: Surgical excision of substernal thyroid goiters is usually achieved through a conventional transcervical approach, and transthoracic excision is rarely necessary. Currently, there are no clear guidelines for substernal thyroid goiters that may require a transthoracic approach. This study examined what preoperative factors were significantly associated with transthoracic surgical excision for substernal thyroid goiters. METHODS: A retrospective review of prospectively collected data of 109 patients with substernal thyroid goiters from a single institution was performed. The patients were stratified by transcervical and transthoracic approaches for substernal thyroid goiters. The factors possibly predictive of a transthoracic approach, including substernal extension beyond the thoracic inlet, patient-reported symptoms, tracheal deviation, and malignancy, were analyzed. Demographics including age, sex, and race, among others, were also studied. RESULTS: Of 1,080 patients who underwent surgical resection for multinodular goiter, there were 109 (10%) patients with substernal thyroid goiters. Of the substernal thyroid goiter group, 11 (10%) patients underwent partial sternotomy, whereas 6 (5.5%) underwent total sternotomy. On logistic regression, only substernal component of the thyroid goiter extending beyond the sternal notch into the mediastinum was statistically significant in predicting sternotomy (odds ratio 3.43, confidence interval 1.65-6.41, P < .001). Substernal thyroid goiters with mediastinal extension of ≥5 cm beyond the sternal notch showed a sensitivity of 94% and specificity of 86.5% to predict need of sternotomy. CONCLUSION: Patients with substernal thyroid goiters who exhibit progressive enlargement and/or compressive symptoms should undergo surgical excision. Although most are removed through the conventional transcervical approach, substernal thyroid goiters with a depth of mediastinal extension ≥5 cm have a high likelihood of requiring sternotomy.

Middle mediastinal cavernous hemangioma: a case report of clinical, pathologic and radiologic features.

Benign vascular tumors of the mediastinum are rare, representing only 0.5% of all mediastinal masses. Given their rare presentation, they are infrequently considered in the workup of a middle mediastinal mass. We present a unique case describing the clinical, imaging and pathologic characteristics of a middle mediastinal cavernous hemangioma which was initially misdiagnosed as a bronchogenic cyst and ultimately required surgical resection with the use of veno-venous extracorporeal membrane oxygenation.

Effect of COVID-19 on the delivery of care for thoracic surgical patients.

Objective: In this study we aimed to determine the effect of the COVID-19 pandemic on the delivery of care for thoracic surgical patients at an urban medical center. Methods: A retrospective analysis of all thoracic surgical cases from May 1, 2019, to December 31, 2020, was conducted. Demographic characteristics, preoperative surgical indications, procedures, final pathologic diagnoses, and perioperative outcomes were recorded. A census of operative cases, relevant ancillary services, and outpatient thoracic clinics were obtained from our institutional database. Results: Six hundred nineteen cases were included in this study (329 pre-COVID-19 and 290 COVID-19, representing an 11.8% reduction). There were no differences in type of thoracic procedures or perioperative outcomes among the 2 cohorts. Prolonged reduction of thoracic surgical cases (50% of baseline) during the first half of the COVID-19 period was followed by a resurgence of surgical volumes to 110% of baseline in the second half. A similar incidence of cases were performed for oncologic indications during the first half whereas more benign cases were performed in the second half, coinciding with the launch of our robotic foregut surgery program. After undergoing surgery during the pandemic, none of our patients reported COVID-19 symptoms within 14 days of discharge. Conclusions: During the initial surge of COVID-19, while there was temporary closure of operative services, our health care system continued to provide safe care for thoracic surgery patients, particularly those with oncologic indications. Since phased reopening, we have experienced a rebound of surgical volume and case mix, ultimately mitigating the initial negative effect of the pandemic on delivery of thoracic surgical care.

Bivalent copper oligopyrocatecholate as a novel heterogeneous catalyst for the oxidative degradation of mercaptan in caustic solution: Synthesis, characterization, and kinetic study.

A novel catalyst based on bivalent copper oligopyrocatecholate was first successfully synthesized and dispersed in a polymer matrix for oxidative degradation of mercaptan in aqueous caustic solution. X-ray diffraction analysis has demonstrated that the synthesized catalyst was a crystalline phase with a minimum amorphous component. Mechanism analysis and kinetic experiments were conducted to investigate the kinetic mechanism of the reaction of isopropyl mercaptan oxidation catalyzed by copper oligopyrocatecholate dispersed in a polymer matrix. The influences of temperature, initial concentrations of reactants, and catalytic surface area on the reaction rate were studied to obtain the rate expression of intrinsic kinetics. The research results showed that the subsequent electron-transfer step was the rate-limiting step of the reaction. Additionally, the mercaptan oxidation rate in caustic solution was inversely proportional to the first power of the alkali concentration. The apparent activation energy was approximately 27.71 ± 1.12 kJ/mol. Importantly, this rate law for mercaptan oxidation can be used to design industrial reactors for the light oil sweetening process.

A Comparison of Current Methods for the Determination of Ra-226 and Ra-228 in Water by a Modified Georgia Tech Gamma Method Vs. US Environmental Protection Agency Drinking Water Methodologies.

ABSTRACT: Radium is a significant source of human radiation exposure both from natural sources (NORM, or Naturally Occurring Radioactive Material) and from technologically enhanced natural radioactive material (TENORM). Gamma analysis for 226Ra and 228Ra in water using high purity germanium (HPGe) detectors was compared with current methods from the US Environmental Protection Agency (EPA) using alpha scintillation and gas proportional counters. Extensive evaluations of a modified version of the original Georgia Tech HPGe method were performed. Known value 226Ra samples from the US Department of Energy (DOE) Mixed-Analyte Performance Evaluation Program (MAPEP) program, mixed 226Ra and 228Ra samples from the Environmental Resource Associates Quality Assurance Program (ERA), and mixed 226Ra and 228Ra samples from the Laboratory Proficiency Testing Program of the International Atomic Energy Agency (IAEA) were used for cross-check comparisons of the modified Georgia Tech method with other methodologies (EPA 903.1 and Ra-05 for 226Ra and 228Ra, respectively). Minimum counting times for our gamma instrumentation to reach a minimum detectable activity (MDA) of 0.04 Bq L-1 were also determined.

Implementation of an enhanced recovery after thoracic surgery care pathway for thoracotomy patients-achieving better pain control with less (schedule II) opioid utilization.

BACKGROUND: Enhanced recovery after surgery protocols incorporate evidence-based practices of pre-, intra- and post-operative care to achieve the most optimal surgical outcome, safe on-time discharge, and surgical cost efficiency. Such protocols have been adapted for specialty-specific needs and are implemented by a variety of surgical disciplines including general thoracic surgery. This study aims to evaluate the impact of our enhanced recovery after thoracic surgery (ERATS) protocol on postoperative outcomes, pain, and opioid utilization following thoracotomy. METHODS: This is a retrospective analysis of patients undergoing elective resection of intrathoracic neoplasms via posterolateral thoracotomy between 1/1/2016 and 3/1/2020. Our enhanced recovery protocol, with a focus on multimodal pain management (opioid-sparing analgesics, infiltration of local anesthetics into intercostal spaces and surgical wounds, and elimination of thoracic epidural analgesia) was initiated on 2/1/2018. Demographics, clinicopathology data, subjective pain levels, peri-operative outcomes, in-hospital and post-discharge opioid utilization were obtained from the electronic medical record. RESULTS: A total of 98 patients (43 pre- and 55 post-protocol implementation) were included in this study. There was no difference in perioperative outcomes or percentage of opioid utilization between the two cohorts. The enhanced recovery group had significantly less acute pain. A significant reduction of in-hospital potent schedule II opioid use was noted following ERATS implementation [average MME: 10.5 (3.5-16.5) (ERATS) vs. 19.5 (12.6-36.0) (pre-ERATS), P<0.0001]. More importantly, a drastic reduction of total and schedule II opioids dispensed at discharge was noted in the ERATS group [total MME: 150 (100.0-330.0) vs. 800.0 (450.0-975.0), P<0.0001 and schedule II MME: 90.0 (0-242.2) vs. 800.0 (450.0-975.0), P<0.0001; ERATS vs. pre-ERATS respectively]. A shorter hospital stay (median difference of 1 day, P=0.0012 and a mean difference of 2.4 days, P=0.0054) was observed in the enhanced recovery group. CONCLUSIONS: Implementation of an enhanced recovery protocol for thoracotomy patients is safe and associated with elimination of thoracic epidural analgesia, decreased postoperative pain, shorter hospitalization, drastic reduction of post-discharge opioid dispensed and decreased dependence on addiction-prone schedule II narcotics.

Comparative Analysis of Robotic Segmentectomy For Non-Small Cell Lung Cancer: A National Cancer Database Study.

OBJECTIVE: The use of segmentectomy for peripheral T ≤2 cm, N0 non-small cell lung cancer (NSCLC) has increased in the last decade. We sought to compare clinical outcomes and overall survival between robotic, video-assisted thoracoscopic surgery (VATS), and open segmentectomy. METHODS: The National Cancer Database was queried for patients with clinical T ≤2 cm, N0 NSCLC who underwent segmentectomy via robotic, thoracoscopic (VATS), and open approaches (2010 to 2015). Univariate and Cox regression analyses were used to compare surgical approaches and to evaluate predictors of overall survival. Statistical analyses were done using SPSS Version 21.0. RESULTS: Segmentectomy was performed in 3,888 patients during the study period with 406 robotic, 1,837 VATS, and 1,645 open patients. VATS and robotic segmentectomy were performed more often at academic or comprehensive community cancer programs as compared to community programs (P < 0.05). Conversion to open thoracotomy was similar between robotic and VATS groups when stratified by hospital volume. Lymph node yield was significantly higher for robotic (median = 6), compared to VATS (median = 5) or open (median = 4; P < 0.001). Length of stay was decreased for robotic versus open (P < 0.01). No differences in 30-day readmissions (P = 0.12) were observed among the 3 modalities. Overall survival was similar among groups (P = 0.18). CONCLUSIONS: Robotic segmentectomy provides similar clinical outcomes compared to other standardized approaches for clinical T ≤2 cm, N0 NSCLC. A higher lymph node yield in robotic segmentectomy was not associated with improved survival in this study population.

Liposomal Bupivacaine Versus Bupivacaine/Epinephrine Intercostal Nerve Block as Part of an Enhanced Recovery After Thoracic Surgery (ERATS) Care Pathway for Robotic Thoracic Surgery.

OBJECTIVES: To examine how postoperative pain control after robotic thoracoscopic surgery varies with liposomal bupivacaine (LipoB) versus 0.5% bupivacaine/1:200,000 epinephrine (Bupi/Epi) intercostal nerve blocks within the context of an enhanced recovery after thoracic surgery (ERATS) protocol. DESIGN: A retrospective analysis of a prospectively maintained database of patients undergoing robotic thoracoscopic procedures between September 1, 2018 and October 31, 2019 was conducted. SETTING: University of Miami, single-institutional. PARTICIPANTS: Patients. INTERVENTIONS: Two hundred fifty-two patients had either LipoB intercostal nerve blocks (n = 129) or Bupi/Epi intercostal nerve blocks (n = 123) when undergoing robotic thoracic surgery. MEASUREMENTS AND MAIN RESULTS: Comparative analysis of patient-reported pain levels, in-hospital and post-discharge opioid requirements, 90-day operative complications, length of hospital stay, and hospital costs was performed. Data were stratified to either anatomic lung resection or pulmonary wedge resection/mediastinal-pleural procedures. Bupi/Epi patients reported significantly more acute postoperative pain than LipoB patients, which correlated with higher in-hospital and post-discharge opioid requirements. There were no differences in postoperative complications, length of hospital stay, or hospital costs between the two groups. CONCLUSIONS: As part of an ERATS protocol, infiltration of intercostal spaces and surgical wounds with LipoB for robotic thoracoscopic procedures afforded better postoperative subjective pain control and decreased opioid requirements without an increase in hospital costs as compared with use of Bupi/Epi.
