Chronic obstructive pulmonary disease (emphysema) is the most common indication for adult lung transplantation. Masitinib As most patients with emphysema (EMP) can survive long term, it could be difficult to decide which patient should be listed for LT. LT is a complex surgery. Therefore, it is extremely important to choose a recipient in whom expected survival is at less equal or comparable to the survival without surgery. This paper reviews patient selection, bridging strategies until lung transplantation, surgical approach and choice of the procedure, and functional outcome in emphysema recipients.Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease associated with significant morbidity and mortality. Over the past few years, there has been cumulating interest in describing this heterogeneity and using this information to group patients into different COPD phenotypes. The term phenotype is defined as single or combination of disease attributes that describe differences between individuals with COPD as they relate to clinically meaningful outcomes. It describes also the physical appearance or biochemical characteristics which result from the genotype-environment interaction. Furthermore, it clearly identifies subgroups with a significant impact in the prognosis. Recently, approaches to COPD phenotyping have been significantly enhanced in tandem with developments in understanding the disease's various pathological, clinical and genetic features. This knowledge inspired the researchers to investigate more tailored therapeutic strategies that could not only give a more potent effect but also help to avoid the traditional therapy's undesirable side effects. Eventually, it could be said that the phenotypic approach to COPD in the last decade had a huge impact on daily practice and management delivered to COPD patients. In this review, we highlight the impact of pharmacological and non-pharmacological treatment options on COPD outcomes, using a personalized treatment strategy based on different phenotypes.Emphysema and lung cancer (LC) are two diseases which share common risk factors, e.g., smoking. In recent years, many studies have sought to analyse this association. By way of illustration, we conducted a review of the scientific literature of the studies published to date, whose main designated aim was to demonstrate the relationship between emphysema and LC, and this association's influence on the histology, prognosis and molecular mechanisms responsible. We included over 40 studies (ranging from case-control and cohort studies to systematic reviews and meta-analyses), which highlight the association between emphysema and LC, independently of smoking habit. These studies also report a possible influence on histology, with adenocarcinoma being the most frequent lineage, and an association with poor prognosis, which affects both survival and post-operative complications. Oxidative stress, which generates chronic inflammatory status as well as the presence of certain polymorphisms in various genes (CYP1A1, TERT, CLPTM1L, ERK), gives rise-in the case of patients with emphysema-to alteration of cellular repair mechanisms, which in turn favours the proliferation of neoplastic epithelial cells responsible for the origin of LC.In the last decades, developing thoracic surgery raised the demands for sophisticated anesthesiological management. Especially patients with end-stage thoracic emphysema challenge the anesthesiologist to make modern surgery possible and to provide a safe and effective perioperative management. The development and scientific work-up of single lung ventilation (SLV) laid the cornerstone for surgery of the non-ventilated lung and hemi-thorax. However, modern medicine extended surgical options to extensive tracheal surgery and to patients suffering from severely insufficient lung-capacity precluding single-lung ventilation or artificial ventilation in se. For those critically ill, different techniques were thus developed and evaluated in recent research, among others, non-intubated surgery and surgery under extracorporeal perfusion support that temporarily avoids pulmonary gas exchange and ventilation via the trachea in any way. To tackle postoperative pain with its successive problems of immobilization, insufficient respiration and airway-clearance, regional anesthesia offers great advantages. Thoracic epidural anesthesia (TEA) is considered as the gold standard; complementary, modern ultrasound techniques make regional anesthesia possible even when contraindications prohibit neuraxial blocks. Especially paravertebral block, musculus serratus anterior block, intercostal block and the musculus erector spinae block provide good postoperative pain relief and appear to influence chronic post-thoracotmy pain positively. Careful preoperative preparation, intraoperative monitoring and patient-tailored, individual perioperative management by a well-trained team ensure good results, a good survival and favorable quality of life. This article provides a brief overview over state-of-the-art techniques and future perspectives to provide anesthesia in emphysema surgery.Emphysema is associated with irreversible loss of lung compliance leading to gas trapping and hyperinflation. Surgical lung volume reduction has proven to improve lung function, exercise capacity, cardiac health and survival in patients with advanced emphysema; however, this procedure is associated with significant morbidity and mortality. Bronchoscopic lung volume reduction (BLVR) has emerged as an alternative approach for these patients. In this article, we review the different techniques used for the purpose of this procedure, its advantages and disadvantages. In addition, we discuss in length valve therapy and the studies that led to its recent FDA approval. Finally, we provide thought-provoking challenges that may be topics for further future investigation to enhance the efficacy and benefit of this technique.
