RESUMO
BACKGROUND: Surgical society guidelines have recommended changing the treatment strategy for early esophageal cancer during the novel coronavirus (COVID-19) pandemic. Delaying resection can allow for interim disease progression, but the impact of this delay on mortality is unknown. The COVID-19 infection rate at which immediate operative risk exceeds benefit is unknown. We sought to model immediate versus delayed surgical resection in a T1b esophageal adenocarcinoma. METHODS: A decision analysis model was developed, and sensitivity analyses performed. The base case was a 65-year-old male smoker presenting with cT1b esophageal adenocarcinoma scheduled for esophagectomy during the COVID-19 pandemic. We compared immediate surgical resection to delayed resection after 3 months. The likelihood of key outcomes was derived from the literature where available. The outcome was 5-year overall survival. RESULTS: Proceeding with immediate esophagectomy for the base case scenario resulted in slightly improved 5-year overall survival when compared to delaying surgery by 3 months (5-year overall survival 0.74 for immediate and 0.73 for delayed resection). In sensitivity analyses, a delayed approach became preferred when the probability of perioperative COVID-19 infection increased above 7%. CONCLUSIONS: Immediate resection of early esophageal cancer during the COVID-19 pandemic did not decrease 5-year survival when compared to resection after 3 months for the base case scenario. However, as the risk of perioperative COVID-19 infection increases above 7%, a delayed approach has improved 5-year survival. This balance should be frequently re-examined by surgeons as infection risk changes in each hospital and community throughout the COVID-19 pandemic.

The association between a Western Diet and colon cancer suggests that dietary factors and/or obesity may contribute to cancer progression. Our objective was to develop a new animal model of obesity and the associated pathophysiology to investigate human cancer independent of dietary components that induce obesity. A novel congenic rat strain was established by introducing the fa allele from the Zucker rat into the Rowett Nude rat to generate a "fatty nude rat". The obese phenotype was first characterized in the new model. To then examine the utility of this model, lean and obese rats were implanted with HT-29 human colon cancer xenografts and tumor growth monitored. Fatty nude rats were visibly obese and did not develop fasting hyperglycemia. Compared to lean rats, fatty nude rats developed fasting hyperinsulinemia, glucose intolerance, and insulin resistance. Colon cancer tumor growth rate and final weight were increased (P < 0.05) in fatty nude compared to lean rats. Final tumor weight was associated with p38 kinase phosphorylation (P < 0.01) in fatty nude rats. We have established a novel model of obesity and pre-type 2 diabetes that can be used to investigate human cancer and therapeutics in the context of obesity and its associated pathophysiology.

Diaphragm injuries are rarely seen injuries in trauma patients and are difficult to diagnose. With improving technology, computed tomography has become more reliable, but with increasing rates of non-operative management of both penetrating and blunt trauma, the rate of missed diaphragmatic injury has increased. The long-term complications of missed injury include bowel obstruction and perforation, which can carry a mortality rate as high as 85%. When diagnosed, injuries should be repaired to reduce the risk of future complications.

Diaphragmatic paralysis is an elevation of the diaphragm caused by a lesion along the neuromuscular axis and may be either bilateral or unilateral. Most commonly, paralysis is unilateral and iatrogenic in nature. Symptoms of this disease may be life-limiting, and when conservative measures fail, surgical therapy may be of significant benefit to patients. With the advent of robotic minimally invasive techniques, diaphragm plication can be a useful therapy for patients with resolution of symptoms, reduced length of hospitalization, and quickened recovery. This article provides an overview of the disease, diagnosis, and current therapies including robotic techniques.

Toward the future goal of creating a lung surgery system featuring multiple tentacle-like robots, we present a new folding concept for continuum robots that enables them to squeeze through openings smaller than the robot's nominal diameter (e.g., the narrow space between adjacent ribs). This is facilitated by making the disks along the robot's backbone foldable. We also demonstrate that such a robot can feature not only straight, but also curved tendon routing paths, thereby achieving a diverse family of conformations. We find that the foldable robot performs comparably, from a kinematic perspective, to an identical non-folding continuum robot at varying deployment lengths. This work paves the way for future applications with a continuum robot that can fold and fit through smaller openings, with the potential to reduce invasiveness during surgical tasks.
RESUMO
Background: Patients who are symptomatic from diaphragmatic dysfunction may benefit from diaphragmatic plication. We recently modified our plication approach from open thoracotomy to robotic transthoracic. We report our short-term outcomes. Methods: We conducted a single-institution retrospective review of all patients who underwent transthoracic plications from 2018, when we began using the robotic approach, to 2022. The primary outcome was short-term recurrence of diaphragm elevation with symptoms noted before or during the first planned postoperative visit. We also compared proportions of short-term recurrences in patients that underwent plication with extracorporeal knot-tying device alone versus those that used intracorporeal instrument tying (alone or supplemental). Secondary outcomes included subjective postoperative improvement of dyspnea at follow-up visit and by postoperative patient questionnaire, chest tube duration, length of stay (LOS), 30-day readmission, operative time, estimated blood loss (EBL), intraoperative complications, and perioperative complications. Results: Forty-one patients underwent robotic-assisted transthoracic plication. Four patients experienced recurrent diaphragm elevation with symptoms before or during their first routine postoperative visit, occurring on POD 6, 10, 37, and 38. All four recurrences occurred in patients whose plications were performed with the extracorporeal knot-tying device without supplemental intracorporeal instrument tying. Proportion of recurrences in the group that used extracorporeal knot-tying device alone was significantly greater than the recurrences in the group that used intracorporeal instrument tying (alone or supplemental) (P=0.016). The majority (36/41) reported clinical improvement postoperatively and 85% of questionnaire respondents also agreed they would recommend the surgery to others with similar condition. The median LOS and of chest tube duration were 3 days and 2 days, respectively. There were two patients with 30-day readmissions. Three patients developed postoperative pleural effusion necessitating thoracenteses and 8 patients (20%) had postoperative complications. No mortalities were observed. Conclusions: While our study shows the overall acceptable safety and favorable outcomes in patients undergoing robotic-assisted transthoracic diaphragmatic plications, the incidence of short-term recurrences and its association with the use of extracorporeally knot-tying device alone in diaphragm plication warrant further investigation.
RESUMO
The use of needles to access sites within organs is fundamental to many interventional medical procedures both for diagnosis and treatment. Safely and accurately navigating a needle through living tissue to a target is currently often challenging or infeasible because of the presence of anatomical obstacles, high levels of uncertainty, and natural tissue motion. Medical robots capable of automating needle-based procedures have the potential to overcome these challenges and enable enhanced patient care and safety. However, autonomous navigation of a needle around obstacles to a predefined target in vivo has not been shown. Here, we introduce a medical robot that autonomously navigates a needle through living tissue around anatomical obstacles to a target in vivo. Our system leverages a laser-patterned highly flexible steerable needle capable of maneuvering along curvilinear trajectories. The autonomous robot accounts for anatomical obstacles, uncertainty in tissue/needle interaction, and respiratory motion using replanning, control, and safe insertion time windows. We applied the system to lung biopsy, which is critical for diagnosing lung cancer, the leading cause of cancer-related deaths in the United States. We demonstrated successful performance of our system in multiple in vivo porcine studies achieving targeting errors less than the radius of clinically relevant lung nodules. We also demonstrated that our approach offers greater accuracy compared with a standard manual bronchoscopy technique. Our results show the feasibility and advantage of deploying autonomous steerable needle robots in living tissue and how these systems can extend the current capabilities of physicians to further improve patient care.

Background: Early-onset gastric cancer (EOGC), or gastric cancer in patients younger than 45 years old, is poorly understood and relatively uncommon. Similar to other gastrointestinal malignancies, the incidence of EOGC is rising in Western countries. It is unclear which populations experience a disproportionate burden of EOGC and what factors influence how patients with EOGC are treated. Methods: We conducted a retrospective, population-based study of patients diagnosed with gastric cancer from 2004 to 2018 using the National Cancer Database (NCDB). In addition to identifying unique demographic characteristics of patients with EOGC, we evaluated (using multivariable logistic regression controlling for year of diagnoses, primary site, and stage) how gender/sex, race/ethnicity, treatment facility type, payor status, and location of residence influenced the receipt of surgery, chemotherapy, and radiation. Results: Compared to patients 45−70 and >70 years of age with gastric cancer, patients with EOGC were more likely to be female, Asian/Pacific Islander (PI), African American (AA), Hispanic, uninsured, and present with stage IV disease. On multivariable analysis, several differences among subsets of patients with EOGC were identified. Female patients with EOGC were less likely to receive surgery and chemotherapy than male patients with EOGC. Asian/Pacific Islander patients with EOGC were more likely to receive chemotherapy and less likely to receive radiation than Caucasian patients with EOGC. African American patients were more likely to receive chemotherapy than Caucasian patients with EOGC. Hispanic patients were more likely to receive surgery and chemotherapy and less likely to receive radiation than Caucasian patients with EOGC. Patients with EOGC treated at community cancer centers were more likely to receive surgery and less likely to receive chemotherapy than patients with EOGC treated at academic centers. Uninsured patients with EOGC were more likely to receive surgery and less likely to receive chemotherapy than privately insured patients with EOGC. Patients with EOGC living in locations not adjacent to metropolitan areas were less likely to receive surgery compared to patients with EOGC who resided in metropolitan areas, Conclusions: Patients with EOGC are a demographically distinct population. Treatment of these patients varies significantly based on several demographic factors. Additional analysis is needed to elucidate why particular groups are more affected by EOGC and how treatment decisions are made for, and by, these patients.
RESUMO
Background and Objective: Low and intermediate grade neuroendocrine tumors of the lung are uncommon malignancies representing 2% of all lung cancers. These are termed typical and atypical pulmonary carcinoid tumors. These can arise in the setting of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH). The presentation, workup, management and outcomes of patients with these tumors can overlap with more common lung cancers but differ in that many of these patients have a prolonged clinical course. The objective of this narrative review is to summarize the literature and provide evidence and expert-based algorithms for work up and treatment of pulmonary carcinoids and DIPNECH. Methods: A search of PubMed and Web of Science databases ending April 15, 2022, with the following keywords "lung carcinoid", "DIPNECH", "lung neuroendocrine," and "bronchopulmonary carcinoid". Key Content and Findings: Pulmonary carcinoid tumors benefit from a multidisciplinary approach. Pre-treatment imaging with contrast-enhanced computed tomography, and DOTATATE positron emission tomography is required. Surgical resection is the gold standard for curative intent, and possibly including sublobar resections. Patients can recur or develop new primaries thus emphasizing the importance of surveillance; national guidelines recommend at least a 10-year follow up. A growing body of literature support the use of endobronchial therapy, with long responses documented. Systemic therapy consists of everolimus, somatostatin analogs, peptide receptor radionuclide therapy, and chemotherapy. Diffuse idiopathic pulmonary neuroendocrine tumor cell hyperplasia is rare, but series suggest somatostatin analogs may confer clinical benefit. Conclusions: Pulmonary carcinoid tumors and DIPNECH are rare. Despite lack of regulatory approvals for advanced disease, multiple options are available but should be sequenced according to the clinical status and disease biology. Each patient should be discussed in a multidisciplinary setting and clinical trials should be considered if available.
RESUMO
BACKGROUND: Women in Thoracic Surgery (WTS) has previously reported on the status of women in cardiothoracic (CT) surgery. We sought to provide a 10-year update on women in CT surgery. METHODS: An anonymous research electronic data capture survey link was emailed to female diplomats of the American Board of Thoracic Surgery. Survey questions queried respondents regarding demographics, training, accolades, practice details, and career satisfaction. The survey link was open for 30 days. Results were compared with The Society of Thoracic Surgeons 2019 workforce survey. Descriptive analyses were performed using frequency and proportions. Comparisons were performed using Student's t tests, Fisher's exact tests, and χ2 tests. RESULTS: Of 354 female diplomats, 309 were contacted and 176 (57%) responded. The majority of respondents were aged 36 to 50 years (59%), white (67.4%), and had graduated from traditional-track programs (91.4%). Most respondents reported practicing in an urban (64%) and academic setting (73.1%). 36.4% and 23.9% reported a general thoracic and adult cardiac practice (22.7% mixed practice, 9.6% congenital). Fifty percent of respondents reported salaries between $400,000 and $700,000 annually; 37.7% reported salaries less than 90% of their male colleagues; 21.6% of respondents in academia are full professor; 53.4% reported having a leadership role. Whereas 74.1% would pursue a career in CT surgery again, only 27.3% agreed that CT surgery is a healthy and positive environment for women. CONCLUSIONS: The number of women in CT surgery has steadily increased. Although women are rising in academic rank and into leadership positions, salary disparities and the CT surgery work environment remain important issues in achieving a diverse work force.

BACKGROUND: Recognition of Anti-tRNA synthetase (ARS) related interstitial lung disease (ILD) is key to ensuring patients have prompt access to immunosuppressive therapies. The purpose of this retrospective cohort study was to identify factors that may delay recognition of ARS-ILD. METHODS: Patients seen at Vanderbilt University Medical Center between 9/17/2017-10/31/2018 were included in this observational cohort. Clinical and laboratory features were obtained via chart abstraction. Kruskal-Wallis ANOVA, Mann-Whitney U, and Fisher's exact t tests were utilized to determine statistical significance. RESULTS: Patients with ARS were found to have ILD in 51.9% of cases, which was comparable to the frequency of ILD in systemic sclerosis (59.5%). The severity of FVC reduction in ARS (53.2%) was comparable to diffuse cutaneous systemic sclerosis (56.8%, p = 0.48) and greater than dermatomyositis (66.9%, p = 0.005) or limited cutaneous systemic sclerosis (71.8%, p = 0.005). Frank honeycombing was seen with ARS antibodies but not other myositis autoantibodies. ARS patients were more likely to first present to a pulmonary provider in a tertiary care setting (53.6%), likely due to fewer extrapulmonary manifestations. Only 33% of ARS-ILD were anti-nuclear antibody, rheumatoid factor, or anti-cyclic citrullinated peptide positive. Patients with ARS-ILD had a two-fold longer median time to diagnosis compared to other myositis-ILD patients (11.0 months, IQR 8.5-43 months vs. 5.0 months, IQR 3.0-9.0 months, p = 0.003). CONCLUSIONS: ARS patients without prominent extra-pulmonary manifestations are at high risk for not being recognized as having a connective tissue disease related ILD and miscategorized as usual interstitial pneumonia/idiopathic pulmonary fibrosis without comprehensive serologies.

Importance: Standard treatment for resectable non-small cell lung cancer (NSCLC) includes anatomic resection with adequate lymph node dissection and adjuvant chemotherapy for appropriate patients. Historically, many patients with early-stage NSCLC have not received such treatment, which may affect the interpretation of the results of adjuvant therapy trials. Objective: To ascertain patterns of guideline-concordant treatment among patients enrolled in a US-wide screening protocol for adjuvant treatment trials for resected NSCLC. Design, Setting, and Participants: This retrospective cohort study included 2833 patients with stage IB to IIIA NSCLC (per American Joint Committee on Cancer 7th edition criteria) who enrolled in the Adjuvant Lung Cancer Enrichment Marker Identification and Sequencing Trial (ALCHEMIST) screening study (Alliance for Clinical Trials in Oncology A151216) from August 18, 2014, to April 1, 2019, and who did not enroll in a therapeutic adjuvant clinical trial; patients had tumors of at least 4 cm and/or with positive lymph nodes. Statistical analysis was conducted from June 1, 2020, through October 1, 2021. Exposures: Care patterns were ascertained overall and by sociodemographic and clinical factors, including age, sex, race and ethnicity, educational level, marital status, geography, histologic characteristics, stage, genomic variant status, smoking history, and comorbidities. Main Outcomes and Measures: Five outcomes are reported: whether patients (1) had anatomic surgical resection, (2) had adequate lymph node dissection (≥1 N1 nodal station plus ≥3 N2 nodal stations), (3) received any adjuvant chemotherapy, (4) received any cisplatin-based adjuvant chemotherapy, and (5) received at least 4 cycles of adjuvant chemotherapy. Results: Of the 2833 patients (1505 women [53%]; mean [SD] age, 66.5 [9.2] years) included in this analysis, 2697 (95%) had anatomic surgical resection, 1513 (53%) had adequate lymph node dissection, 1617 (57%) received any adjuvant chemotherapy, 1237 (44%) received at least 4 cycles of adjuvant platinum-based chemotherapy, and 965 (34%) received any cisplatin-based adjuvant chemotherapy. Rates were similar across race and ethnicity. Conclusions and Relevance: This cohort study found that among participants in a screening protocol for adjuvant clinical trials for resected early-stage NSCLC, just 53% underwent adequate lymph node dissection, and 57% received adjuvant chemotherapy, despite indications for such treatment. These results may affect the interpretation of adjuvant trials. Efforts are needed to optimize the use of proven therapies for early-stage NSCLC. Trial Registration: ClinicalTrials.gov Identifier: NCT02194738.

Tumor-induced osteomalacia (TIO), caused by phosphaturic mesenchymal tumors (PMTs), is a rare paraneoplastic syndrome characterized by frequent bone fractures, bone pain, muscle weakness, and affected gait. These tumors typically secrete high levels of Fibroblastic Growth Factor 23 (FGF23), a hormone which acts on the kidney to cause hypophosphatemia, ultimately impairing bone mineralization. In this case report, we present a 41-year-old female with FGF23-mediated hypophosphatemia with a 26-year delay in TIO diagnosis and a concurrent misdiagnosis of X-linked hypophosphatemic rickets (XLH). Given an absence of family history of hypophosphatemia, a 13-gene hypophosphatemia panel including XLH (PHEX gene) was performed and came back negative prompting a diagnostic search for a PMT causing TIO. A 68Ga-DOTATATE PET/CT scan revealed the presence of a 9th right rib lesion, for which she underwent rib resection. The patient's laboratory values (notably serum phosphorus, calcium, and vitamin D) normalized, with FGF23 decreasing immediately after surgery, and symptoms resolving over the next three months. Chromogenic in situ hybridization (CISH) and RNA-sequencing of the tumor were positive for FGF23 (CISH) and the transcriptional marker FN1-FGFR1, a novel fusion gene between fibronectin (FN1) and Fibroblast Growth Factor Receptor 1 (FGFR1), previously determined to be present in the majority of TIO-associated tumors. This case demonstrates the notion that rare and diagnostically challenging disorders like TIO can be undiagnosed and/or misdiagnosed for many years, even by experienced clinicians and routine lab testing. It also underscores the power of novel tools available to clinicians such as gene panels, CISH, and RNA sequencing, and their ability to characterize TIO and its related tumors in the context of several phenotypically similar diseases.
RESUMO
INTRODUCTION: Indwelling pleural catheters (IPC) are effective at palliating benign and malignant pleural effusions (MPE). They have also been found to be cost effective from a third-party payor perspective. Little is known of the impact IPCs have on patient-centered quality of life outcomes such as financial burden and patient and caregiver burden. We performed a cross-sectional survey study evaluating the impact of IPCs on multiple patient and caregiver quality of life metrics. METHODS: Patients ≥ 18 years old with an IPC in place for 2 months were eligible. Twenty patients were recruited over a 10-month period. Patients completed the CDC-Health Related Quality of Life (HRQOL)-4 and a HRQOL-financial questionnaire. The primary objective was to describe the socio-economic impact of IPCs. Demographic and IPC specific data were collected. Descriptive statistics were used. RESULTS: The mean (SD) age was 64.3 (0.70). The indication was MPE in 19/20. All patients had medical insurance. Medicare or Medicaid (CMS) comprised 10/20 of payors. The median (IQR) copay for private insurers was $238.45 (72-875); 11/20 had additional costs related to the IPC; 4/20 had significant life changes after the IPC; 17/20 received assistance from a non-paid caregiver; 6/20 patients could not do activities because of the IPC and this negatively impacted QOL in 3/6 of those patients. CONCLUSION: Patients with IPCs may experience negative life consequences, incur additional medical expenses, and require assistance from a non-paid caregiver. Activities may be negatively impacted by IPC. Discussion of alternative means of symptom palliation and pleurodesis would be beneficial.

Rationale: Recent trends in the care and outcomes of pleural infection are not well characterized.Objectives: To investigate trends in hospital-based healthcare use, outcomes, and management of pleural infection across the United States.Methods: We identified adult hospitalizations for pleural infection from 2005 through 2014 in the Healthcare Cost and Utilization Project-National Inpatient Sample using International Classification of Diseases, Ninth Edition Clinical Modification diagnosis codes. We calculated weighted estimates of national trends in hospitalization, hospital length of stay, hospital mortality, inflation-adjusted cost, and management practices. We tested trend significance using fitted regression models.Results: Over one decade, there was a significant decline in hospitalizations (54.4 per million to 41.2 per million U.S. adult population), length of stay (13.5 ± 0.2 to 11.2 ± 0.2 d), mortality (4.2-2.6%), and costs ($32,829 to $29,458) (all P < 0.001). Both tube thoracostomy and video-assisted thoracoscopic surgery saw an increase as the procedure of first choice, along with declining use of thoracotomy (all P < 0.001). Most patients who underwent video-assisted thoracoscopic surgery (94%) or tube thoracostomy (64.9%) as the initial procedure did not require a second invasive procedure.Conclusions: Over the 21st century's first decade and a half, inpatient costs, use, and mortality have improved among U.S. adults hospitalized with pleural infection. Simultaneously, there has been a shift toward less invasive interventions upfront.

BACKGROUND: The COVID-19 pandemic has overwhelmed hospital systems in multiple countries and necessitated caring for patients in atypical healthcare settings. The goal of this study was to ascertain if the conventional critical care severity scores qSOFA, SOFA, APACHE-II, and SAPS-II could predict which patients admitted to the hospital from an emergency department would eventually require intensive care. METHODS: This single-center, retrospective cohort study enrolled patients admitted to Vanderbilt University Hospital from the emergency room with symptomatic, confirmed COVID-19 infection between March 8, 2020 through May 15, 2020. Clinical phenotyping was performed by chart abstraction, and the correlation of the qSOFA, SOFA, APACHE-II, and SAPS-II scores for the primary endpoint of ICU admission and secondary endpoint of in-hospital mortality was evaluated. RESULTS: During the study period, 128 patients were admitted to Vanderbilt University Hospital from the emergency room with COVID-19. Of these, 39 patients eventually required intensive care; the remaining 89 were discharged from the medical ward. All severity of illness scores demonstrated at least moderate ability to identify patients who would die or require ICU admission. Of the three severity of illness scores assessed, the APACHE-II score performed best with an AUC of 0.851 (95% CI: 0.786 to 0.917) for identifying patient that would require ICU admission. No patient with an APACHE-II score at the time of presentation less than 8 or qSOFA of 0 required intensive care unit (ICU) admission. All patients with an APACHE-II score less than 10 or qSOFA score of 0 survived to hospital discharge. CONCLUSIONS: The APACHE-II score accurately predicts the eventual need for ICU admission. This may allow for risk-stratification of patients safe to treat in alternative health care settings and prognostic enrichment to accelerate clinical trials of COVID-19 therapies.
RESUMO
BACKGROUND: Surgical decortication is recommended by national guidelines for management of early empyema, but intrapleural fibrinolysis is frequently used as a first-line therapy in clinical practice. This study compared the cost-effectiveness of video-assisted thoracoscopic surgery (VATS) decortication with intrapleural fibrinolysis for early empyema. METHODS: A decision analysis model was developed. The base clinical case was a 65-year-old man with early empyema treated either by VATS decortication or intrapleural tissue plasminogen activator and deoxyribonuclease. The likelihood of key outcomes occurring was derived from the literature. Medicare diagnosis-related groups and manufacturers' drug prices were used for cost estimates. Successful treatment was defined as complete or nearly complete resolution of empyema on imaging. Effectiveness was defined as health utility 1 year after empyema. RESULTS: Intrapleural tissue plasminogen activator and deoxyribonuclease were more cost-effective than VATS decortication for treating early empyema for the base clinical case. Surgical decortication had a slightly lower cost than fibrinolysis ($13,345 vs $13,965), but fibrinolysis had marginally higher effectiveness at 1 year (health utility of 0.80 vs 0.71). Therefore, fibrinolysis was the more cost-effective option. Sensitivity analyses found that fibrinolysis as the initial therapy was more cost-effective when the probability of success was greater than 60% or the initial cost was less than $13,000. CONCLUSIONS: Surgical decortication and intrapleural fibrinolysis have nearly equivalent cost-effectiveness for early empyema in patients who can tolerate both procedures. Surgeons should consider patient-specific factors, as well as the cost and effectiveness of both modalities, when deciding on an initial treatment for early empyema.

BACKGROUND: We examined how intercostal nerve block (ICNB) with standard bupivacaine and ICNB with extended-release liposomal bupivacaine, compared with thoracic epidural analgesia (TEA), were associated with postoperative opioid pain medication consumption and hospital length of stay (LOS) after thoracic surgery. METHODS: We studied 1935 patients who underwent thoracic surgery between January 1, 2010, and November 30, 2017, at a tertiary academic center. Primary and secondary outcomes were postoperative opioid consumption expressed as morphine milligram equivalents (MMEs) at 24, 48, and 72 hours after surgery, the LOS, and total MME consumption from surgery to discharge. RESULTS: Of these patients, 888 (45.9%) received TEA, 730 (37.7%) ICNB with standard bupivacaine, 127 (6.6%) ICNB with liposomal bupivacaine, and 190 (9.8%) no regional analgesia. Compared with epidural analgesia, in 2017, ICNB liposomal bupivacaine provided similar pain control in terms of MME consumption at 24 and 72 hours, but decreased MME consumption at 48 hours (odds ratio [OR] = 0.33; confidence interval [CI] = 0.14-0.81) and at discharge (OR = 0.28; CI = 0.12-0.68) and was associated with a higher likelihood for a shorter LOS (hazard ratio = 3.46; CI = 2.42-4.96). Compared with TEA, ICNB with standard bupivacaine and no regional analgesia use showed varying impact on MME consumption between 24 and 72 hours after surgery, and their use was not associated with a significantly reduced MME consumption at discharge but with a shorter hospital LOS. CONCLUSIONS: Multimodal analgesia involving regional anesthetic alternatives to TEA could help manage postoperative pain in thoracic surgery patients.

Introduction: Patients with previous coronary artery bypass graft (CABG) are usually considered as high-risk groups perioperatively. Recent studies suggest that previous CABG is not associated with mortality in patients with severe aortic stenosis (AS) who underwent transcatheter aortic valve replacement (TAVR). However, systematic review and meta-analysis of the literature has not been done. Thus, we conducted this systematic review and meta-analysis to assess the association between previous CABG and mortality in patients undergoing TAVR.Methods: We comprehensively searched the databases of MEDLINE and EMBASE from inception to July 2018. Included studies were published prospective or retrospective cohort studies that evaluated the effects of previous CABG status on mortality risk among patients undergoing TAVR. Data from each study were combined using the random-effects, generic inverse variance method of DerSimonian and Laird to calculate risk ratios and 95% confidence intervals.Results: Eleven cohort studies from March 2010 to April 2018 were included in this meta-analysis involving 7299 subjects with severe AS undergoing TAVR (1890 with and 5409 without previous CABG). Previous CABG was not associated with all-cause mortality (pooled risk ratio = 0.96, 95% confidence interval: 0.80-1.16, p=.66, I2=21%) and cardiovascular (CV) mortality (pooled risk ratio = 1.23, 95% confidence interval: 0.64-2.39, p=.72, I2=35%).Conclusions: Previous CABG is not associated with either all-cause mortality or CV mortality in patients with severe AS undergoing TAVR. TAVR should be considered as an alternative or first-line treatment option among severe AS patient, regardless of previous CABG status.
