Pathology arising from the intrathoracic portion of the trachea (distal trachea), the carina and the main bronchi is usually neoplastic and is mainly treated with surgery. Resection of the intrathoracic portion of the trachea, the carina and the main bronchi for neoplastic lesions does not necessitate lung resection and is traditionally being conducted via open surgery. Video-assisted thoracic surgery (VATS) is witnessing an exponential growth and is the treatment of choice for early-stage non-small cell lung cancer (NSCLC). The experience accumulated over the past two decades along with the introduction of reliable and ergonomic technology, has led to the expansion of its indications. In this article we provide a detailed description of lung sparing distal tracheal, carinal and main bronchi resection for primary neoplasms of the airway, without involvement of the lung, with the uniportal video-assisted technique. LOXO-292 The chest is entered through the fourth intercostal space, mid-axillary line. Dissection of the paratracheal space anteriorly, the tracheoesophageal groove posteriorly and the subcarinal space and division of the azygos arch are essential to mobilize the distal trachea and carina. Lateral dissection should be avoided beyond the points of division of the airway, as it may hinder the blood supply to the anastomosis. Any tension to the anastomosis should be relieved by release maneuvers. Ventilation is achieved through an endobronchial catheter, inserted into the left main bronchus through which a high-frequency jet ventilation catheter can be also inserted through it. The rationale of applying a minimally invasive technique for the conduction of tracheal and carinal resections, is to exploit its advantages, namely less pain, earlier mobilization and lower morbidity. Uniportal video-assisted resections of the distal trachea, carina and the main bronchi, are safe when conducted by experienced surgical and anesthetic teams.Tracheotomy is a surgical procedure commonly employed to establish stable and long-term airway access. Iatrogenic airway injury post procedure may have serious consequences with limited treatment options. Tracheostoma or long standing tracheostomies require special closing techniques. Tracheotomies, tracheostomies, complications of these and treatment options, long standing tracheostomy closure techniques, and standard tracheal segmental resections are discussed.Prevention of bronchial complications after airway surgery must be our primary goal. Understanding bronchial and anastomotic healing is the first step to success. This can be improved by standardizing operating technique (bronchial closure and end-to-end anastomosis) as well as postoperative care. Bronchopleural fistula after pneumonectomy still remains a feared complication with a high mortality rate. Especially after sleeve resection interpretation of endobronchial healing and postoperative measures of care with the help of an algorithm, may avoid anastomotic insufficiency and therefore reduced the secondary pneumonectomy rate.Robotic technology is positioned to transform the approach to tracheobronchial surgery. With its magnified 3D view, intuitive controls, wristed-instruments, high-fidelity simulation platforms, and the steady implementation of new technical improvement, the robot is well-suited to manage the careful dissection and delicate handling of the airway in tracheobronchial surgery. This innovative technology has the potential to promote the widespread adoption of minimally invasive techniques for this complex thoracic surgery.Anatomic resections with bronchial and/or vascular resections and reconstruction, so called sleeve resections were originally performed in patients with impaired cardio-pulmonary reserves. Nowadays, sleeve resections are established surgical procedures of first choice for tracheobronchial pathologies, whenever anatomically and oncologically feasible. Experienced thoracic surgeons have a broad surgical armentarium to avoid a pneumonectomy and the morbidity and mortality associated with it. Sleeve resections are associated with better outcomes in all aspects. Thus, sleeve resection is not an alternative for pneumonectomy and vice versa. In this review article we set out to provide a contemporary overview on this topic.Cervical stenosis of the trachea caused by tracheotomy, tumor or induced by inflammatory disease can be treated by resection and anastomosis with good early and long-term results. Involvement of the ring cartilage makes the procedure technical demanding and increases the risk of morbidity. We describe our technique of laryngotracheal resection and reconstruction and compare the perioperative results with standard trachea resection. Between January 2005 and September 2018, we performed 92 standard cervical tracheal resections and 50 laryngotracheal resection including 6 procedures with widening of the ring cartilage. The resections were realized by direct anastomosis using dorsal flaps and/or interposition of rib cartilage in the posterior part of the ring cartilage. In one case intraoperative tracheotomy and intralaryngeal stenting was used. Patient records have been analyzed for perioperative data retrospectively. The main cause for stenosis or defect of the trachea and operation is preceding tracheotomy. Idiopathic stenosis, tumors and subglottic stenosis in Wegener disease are less common. Healing of the anastomosis was not disturbed in any patient. In two patients, bronchoscopic resection of granulation tissue was necessary. Tracheotomy in the course of treatment for intralaryngeal swelling or recurrent nerve palsy was necessary in 3 patients including one intraoperative tracheotomy for glottic stenting. Postoperative tracheostomy was closed in all patients within 3 months. Pulmonary complications and persistent recurrent nerve palsy occurred in 4 and 2 of the patients, respectively. Two patients died of pulmonary complications. The laryngotracheal resection is a relevant part of cervical tracheal surgery. It can be performed without significant elevated morbidity and is able to restore lung function and quality of voice.Tracheobronchial injuries (TBI) are a heterogenous group of sometimes life-threatening traumas with different management approaches. Symptoms are mediastinal and subcutaneous emphysema, bloody secretions from the airway or haemoptysis in alert patients, and high air leakage along the cuff or increased ventilatory resistance may be signs for TBI in intubated patients. The necessity of immediate clinical evaluation, CT-scan and bronchoscopic evaluation are essential for prompt diagnosis and classification as well as experienced air way management and treatment, these patients are best managed from interdisciplinary teams including thoracic surgeons. While iatrogenic tracheal membrane laceration from intubation can be treated by lesion bridging with ventilation tube, stent application, open operative repair or endoluminal repair, intraoperative accidental cuts should be repaired by direct suture or with vital tissue coverage in case of local ischemia. The management of blunt or penetrating injury is sequential and needs immediate establishment and maintenance of a secure patent airway to provide adequate oxygenation. The next step is the treatment of life-threatening collateral injuries like major hemorrhage, cranial trauma or major organ damage arranged in the trauma team. The treatment of penetrating injuries to the airway need operative exploration in almost every case with minimal local dissection and debridement followed by direct repair. Muscle flap coverage is useful in case of combined esophageal injury. Damage of the tracheobronchial tree after blunt trauma must be repaired by direct suture or local tissue sparing resection and anastomosis. These lesions can be missed in the initial phase and may become prominent with scar tissue formation, stenosis and atelectasis in the later phases.Tracheobronchial pathology can be related to trauma, infection, tumor, or a combination of these. Per definition, planning for tracheobronchial surgery can be complicated by the overlap of anesthesiological interests in airway management and the primary surgical field. Therefore, following a detailed description of the stenosis, management of tracheobronchial surgery requires an interdisciplinary discussion and individualized planning of the procedure. There are several options for intraoperative ventilation depending on the exact localization of the defect. Hence, different tubes and ventilation techniques from cross-field ventilation, to jet ventilation, or even spontaneous breathing under regional anesthesia, have to be discussed. Moreover, an innovative ventilation mode called flow-controlled ventilation (FVC) has been developed, which allows to apply standard tidal volumes through a narrow-bore endotracheal tube. In addition, the Ventrain has been developed as an emergency device following the same technique of an active expiration based on the Venturi principle and a controlled gas flow. In critical situations, it allows even ventilation through the working channel of a bronchoscope. Overall, tracheobronchial surgery is performed under total intravenous anesthesia and the aim of an early extubation at the end of surgery. Airway management has to be discussed and planned between surgeon and anesthesiologist. All of the steps of the procedure need constant and clear communication.Airway remodeling, as a major characteristic of bronchial asthma, is critical to the progression of this disease, whereas it is of less importance in clinical management. Complying with the current stepwise treatment standard for asthma, the choice of intervention on the clinical status is primarily determined by the patient's treatment response to airway inflammation. However, a considerable number of asthmatic patients, especially severe asthmatic subjects, remain uncontrolled though they have undergone fortified anti-inflammation treatment. In the past few years, a growing number of biologics specific to asthma phenotypes have emerged, bringing new hope for patients with refractory asthma and severe asthma. While at the same time, the effect of airway remodeling on asthma treatment has become progressively prominent. In the era of personalized treatment, it has become one of the development directions for asthma treatment to find reliable airway remodeling biomarkers to assist in asthma phenotypes classification, and to further combine multiple phenotypes to accurately treat patients. In the present study, the research status of airway remodeling in asthma is reviewed to show the basis for classifying and treating such disease. Besides, several selected airway remodeling biomarkers and possibility to use them in individual treatment are discussed as well. This study considers that continuously optimized mechanisms and emerging biomarkers for airway remodeling in the future may further support individual therapy for asthma patients.Small cell lung cancer (SCLC), a particular neuroendocrine tumor, occupies 13% of lung cancers, with the highest mortality among cancers. Immune checkpoints inhibitors (ICIs) based on programmed cell death protein-1 (PD-1)/programmed cell death one ligand (PD-L1) inhibitors and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors have been one of the most favorable therapies in SCLC. Simultaneously, not all the patients respond to ICIs due to the lack of biomarkers to predict the immunotherapeutic effect. Multiple combinational approaches are under exploration, including the integrated or successive assessment of additional immunotherapeutic agents, chemotherapy, radiotherapy, and targeted therapy with ICIs. The current review offers a general view of the rationale for clinical studies exploring the experimental result of combinational immunotherapy based on ICIs, with both available results and ongoing trials. Moreover, the development of more predictive biomarkers, specific clinical trial designs, enhancement of the efficacy, and decreasing the financial toxicity will become the trend of future research and clinical applications of ICIs.
