Background: Prone positioning has become a standard therapy in acute respiratory distress syndrome to improve oxygenation and decrease mortality. However, little is known about prone positioning in lung transplant recipients. This large, singe-center analysis investigated whether prone positioning improves gas exchange after lung transplantation.

Article Synopsis
  • This study looked at a problem called primary graft dysfunction that can happen after lung transplants, where the new lungs don't work well due to injury during the operation.
  • Researchers tested whether using a special filter that removes harmful substances from the blood right after transplant would help the new lungs work better in pigs.
  • The results showed that the filter didn't actually help, as the levels of some proteins that cause inflammation were even higher in the group that got the filter, and there were no big differences in how well the lungs worked.

Objective: To clarify the relationship between the use of extracorporeal life support during lung transplantation and severe primary graft dysfunction (PGD), we developed and analyzed a novel multicenter international registry.

Methods: The Extracorporeal Life Support in Lung Transplantation Registry includes double-lung transplants performed at 8 high-volume centers (>40/year). Multiorgan transplants were excluded.

Large solitary cystic lesions are a rare finding, and their differential diagnosis includes cystic airspaces associated with lung cancer, congenital pulmonary airway malformations and pneumatoceles. Here, we report 3 consecutive patients who presented with a large solitary pulmonary cyst on chest computed tomography. All underwent surgical resection, and the histopathological findings were different in all 3 cases.

Mobility programs can be a valuable enhancement to medical formation and career, either during or after training as part of an internship or as a fellowship. In the case of surgery, the opportunity to visit departments who offer a broader range of operations than the home institution, learn new clinical and surgical techniques are unique possibilities to expand surgical and clinical daily routine practice but also to meet colleagues and exchange experiences for future collaboration and networking.

Objectives: A tension-free anastomosis is crucial to minimize the risk of airway complications after laryngotracheal surgery. The 'guardian' chin stitch is placed to prevent hyperextension of the neck in the early postoperative period. This manoeuvre was introduced early in tracheal surgery and is now routinely performed by many airway surgeons.

Objective: Single-stage laryngotracheal reconstruction (SSLTR) provides a definite surgical treatment for patients with complex glotto-subglottic stenosis. To date, the influence of SSLTR on the functional outcome after surgery has not been analyzed.

Methods: A retrospective analysis of all patients receiving a SSLTR between November 2012 and October 2019 was performed.

Article Synopsis
  • Primary graft dysfunction (PGD) is a significant issue following lung transplantation, often linked to ischemia-reperfusion injury.
  • In a study with 12 pigs, researchers compared low-flow (LF) and high-flow (HF) conditions during single-left lung transplants, assessing the effects on lung function and injury.
  • Results showed no significant differences in survival or lung injury between the LF and HF groups in the first 6 hours post-transplant, suggesting that increased blood flow didn’t impact ischemia-reperfusion injury but may inform future transplantation studies.

Because of the differing definitions of the margins of thoracic surgery as a specialty and the variability in the training curricula among European countries, the European Society of Thoracic Surgeons formed a task force to elaborate a consensual proposal. The first step comprised creating a harmonized syllabus that was completed and published in 2018. This publication presents a proposal for a curriculum upon which the task force and the external expert reviewers have agreed.

Objectives: Combined modality treatment (CMT) for malignant pleural mesothelioma (MPM) remains a matter of debate regarding the choice of surgical procedure: extrapleural pneumonectomy (EPP) or pleurectomy/decortication.

Methods: We performed a prospective interventional cohort study between 2003 and 2014. All consecutive patients with any histological MPM subtype, ≤70 years old, World Health Organization performance status ≤1, medically fit for pneumonectomy and stage cT1-2cN0-2cM0 (TNM7) or lower were included.

Duration and content of Thoracic surgery training differs considerably across Europe, leading to unequal levels of knowledge, skills and attitudes at the time of graduation as a specialist. The European Board of Thoracic Surgery examination strives to overcome these regional differences by offering a diploma to achieve harmonization and equal qualified certification. The HERMES initiative, driven by a joint task force from European Society of Thoracic Surgeons (ESTS) and European Respiratory Society (ERS) is currently establishing a consensual syllabus and curriculum for Thoracic Surgery to standardize content of training and achieve equal levels of qualification all-over Europe.
