The Impact of Balloon Use during Endobronchial Ultrasound: A Randomized Pilot Study.

Introduction: During endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA), a saline-filled balloon placed over the tip of the bronchoscope is used to improve coupling of the ultrasound transducer to the airway wall. However, it is unknown whether it objectively improves image quality or affects procedural outcomes. Our aim was to establish whether the use of a balloon during EBUS impacts image quality, diagnostic yield, procedure duration or complications.

ISHLT consensus statement on the perioperative use of ECLS in lung transplantation: Part II: Intraoperative considerations.

The use of extracorporeal life support (ECLS) throughout the perioperative phase of lung transplantation requires nuanced planning and execution by an integrated team of multidisciplinary experts. To date, no multidisciplinary consensus document has examined the perioperative considerations of how to best manage these patients. To address this challenge, this perioperative utilization of ECLS in lung transplantation consensus statement was approved for development by the International Society for Heart and Lung Transplantation Standards and Guidelines Committee.

Impact of Transplant Body Mass Index and Post-Transplant Weight Changes on the Development of Chronic Lung Allograft Dysfunction Phenotypes.

Introduction: Chronic lung allograft dysfunction (CLAD) is a lung transplant complication for which four phenotypes are recognized: Bronchiolitis obliterans syndrome (BOS), Restrictive allograft syndrome (RAS), mixed and undefined phenotypes. Weight gain is common after transplant and may negatively impact lung function. Study objectives were to describe post-transplant weight trajectories of patients who developed (or did not) CLAD phenotypes and examine the associations between BMI at transplant, post-transplant changes in weight and BMI, and the risk of developing these phenotypes.

Intersurgeon variations in postoperative length of stay after video-assisted thoracoscopic surgery lobectomy.

Objectives: To identify factors associated with prolonged postoperative length of stay (LOS) after VATS lobectomy (VATS-L), explore potential intersurgeon variation in LOS and ascertain whether or not early discharge influences hospital readmission rates.

Methods: We conducted a retrospective analysis of patients who underwent VATS-L at a single academic center between 2018 and 2021. Each VATS lobectomy procedure was performed by 1 of 7 experienced thoracic surgeons.

Randomized trial of routine versus on-demand intraoperative extracorporeal membrane oxygenation in lung transplantation: A feasibility study.

In most centers, extracorporeal membrane oxygenation (ECMO) is the preferred means to provide cardiopulmonary support during lung transplantation. However, there is controversy about whether intraoperative venoarterial (VA) ECMO should be used routinely or selectively. A randomized controlled trial is the best way to address this controversy.

Outside the Cage Subcostal RATS Lobectomy: Technical Aspects and Results of the First Series of a Novel Approach to Pulmonary Lobectomy.

Objective: The goal of minimally invasive surgery is to reduce trauma to patients and improve their postoperative outcomes. In this context, the utilization of robot-assisted thoracic surgery (RATS) in the treatment of lung cancer has increased worldwide. The feasibility of single-incision major pulmonary resections by RATS was recently reported, with the objective of minimizing the surgical trauma of the traditional multiportal RATS approach.

Surgical Cost Awareness Program Study: Impact of a Novel, Real-Time, Cost Awareness Intervention on Operating Room Expenses in Thoracoscopic Lobectomy.

Background: For surgical patients, operating room expenses are significant drivers of overall hospitalization costs. Surgical teams often lack awareness of the costs associated with disposable surgical supplies, which may lead to unnecessary expenditures. The aim of this study is to evaluate whether a Surgical Cost Awareness Program would reduce operating room costs.

Correlation between Neutrophil Extracellular Traps (NETs) Expression and Primary Graft Dysfunction Following Human Lung Transplantation.

Primary graft dysfunction (PGD) is characterized by alveolar epithelial and vascular endothelial damage and inflammation, lung edema and hypoxemia. Up to one-third of recipients develop the most severe form of PGD (Grade 3; PGD3). Animal studies suggest that neutrophils contribute to the inflammatory process through neutrophil extracellular traps (NETs) release (NETosis).

New-onset Obesity After Lung Transplantation: Incidence, Risk Factors, and Clinical Outcomes.

Background: Lung transplant (LTx) recipients who gain weight after transplantation may experience an upward shift in body mass index (BMI) that places them in the obese category. The incidence, risk factors, and impact on metabolic health and mortality of new-onset obesity have not been documented in the LTx setting.

Methods: This single-center retrospective study included 564 LTx recipients.

Post-Operative Outcomes Associated With Open Versus Robotic Thymectomy: A Propensity Matched Analysis.

To compare post-operative outcomes associated with thymectomy performed using either open or robotic approaches. Retrospective cohort study from a single-center prospective registry consisting of patients undergoing thymectomy between 2000 and 2020. Patients were grouped according to surgical approach (open vs robotic).

Impact of Volume on Mortality and Hospital Stay After Lung Cancer Surgery in a Single-Payer System.

Background: There is a literature gap for hospitals in single-payer health care systems quantifying the influence of hospital volume on outcomes after major lung cancer resection. We aimed to determine the effect of hospital volume on mortality and length of stay.

Methods: A retrospective cohort study using administrative, population-based data from a single-payer universal health care system was performed in adults with non-small cell lung cancer who underwent lobectomy or pneumonectomy between 2008 and 2017.

Recent Findings: The number of lung transplants performed worldwide is increasing.

Balloon Dilation for Endosonographic Staging in Esophageal Cancer: A Phase 1 Clinical Trial.

Background: Dilation in patients with malignant esophageal strictures precluding the passage of the endoscopic ultrasonography (EUS) scope allows complete evaluation; however, it may be associated with complications. This study evaluates the safety and clinical value of balloon dilation to complete EUS in patients with stenotic esophageal cancers.

Methods: This study consists of a phase I clinical trial.

HSP90 Inhibitor Improves Lung Protection in Porcine Model of Donation After Circulatory Arrest.

Background: Ischemia-reperfusion associated with prolonged warm ischemia during donation after circulatory death (DCD) induces acute lung injury. The objective of this study was to combine ex vivo lung perfusion (EVLP) and a heat shock protein-90 inhibitor (HSP90i) to recondition DCD organs and prevent primary graft dysfunction.

Methods: Pigs (55 to 65 kg) were anesthetized, ventilated, and hemodynamically monitored.

Increased Calculated Panel Reactive Antigen Is Associated With Increased Waitlist Time and Mortality in Lung Transplantation.

Background: Sensitized candidates with unacceptable antigens are a group that demands special attention in organ transplantation. Calculated panel reactive antigen (cPRA) is not used to modify allocation priorities in lung transplantation. The impact of cPRA on waiting list time and mortality is unknown.

Trends, Determinants, and Impact on Survival of Post-Lung Transplant Weight Changes: A Single-center Longitudinal Retrospective Study.

Background: Weight gain is commonly seen in lung transplant (LTx) recipients. Although previous studies have focused on weight changes at fixed time periods and relatively early after transplant, trends over time and long-term weight evolution have not been described in this population. The study objectives were to document weight changes up to 15 years post-LTx and assess the predictors of post-LTx weight changes and their associations with mortality.

Transvascular endosonographic-guided needle biopsy of intrathoracic lesions.

Background: Endoscopic ultrasound-guided biopsy techniques, including endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), are currently the standard of care for the assessment of mediastinal lymphadenopathy. Traditionally, passing the needle through and through vascular structures has been avoided owing to the risk of bleeding. In this study, we evaluated the safety and diagnostic accuracy of transvascular endosonographic-guided biopsies of mediastinal, hilar and lung lesions.
