Lung volume reduction surgery (LVRS) can be performed in patients with severe emphysematous disease. However, LVRS in pediatric patients has not yet been reported. Here, we report our experience with 2 cases of pediatric LVRS. The first patient was a preterm infant girl with severe bronchopulmonary dysplasia, pulmonary hypertension, and hypothyroidism. The emphysematous portion of the right lung was removed via sternotomy and right hemiclamshell incision. The patient was discharged on full-time home ventilator support for 3 months after the surgery...

OBJECTIVES: Pulmonary hypertension (PH) is considered a contraindication for lung volume reduction surgery (LVRS). Because, it has been reported that endobronchial lung volume reduction may have a beneficial effect without increased mortality in patients with emphysema and PH, we evaluated its effect on PH in patients undergoing LVRS. METHODS: From January 2014 until June 2016, 119 LVRSs were performed at Zurich University Hospital. PH was a contraindication for patients with homogeneous emphysema but was acceptable for those with heterogeneous emphysema...

Lung volume reduction surgery (LVRS) offers improvement in lung function, quality of life and even survival in well selected patients with severe emphysema. Patients with all types of emphysema morphology can profit from LVRS when certain selection criteria are present. Hyperinflation plays a key role in qualifying for the procedure. Candidate selection should be performed at high volume centers with a multidisciplinary emphysema board. Qualified thoracic surgeons together with pulmonologists and radiologists identify the suitable patient considering emphysema morphology with its target areas for resection, lung function parameters and cardiac comorbidities...

BACKGROUND: Lung volume reduction surgery (LVRS) has been proven to be a successful procedure and can be performed with low mortality when defined selection criteria are met. We hypothesized good outcome and low mortality after LVRS for selected patients with severe hyperinflation and nonhomogeneous morphology even when diffusion capacity of the lung for carbon monoxide (Dlco) is less than 20%. METHODS: The study included all patients scheduled for LVRS between March 2005 and May 2014 with a preoperative Dlco of less than 20%...

OBJECTIVES: Lung volume reduction surgery (LVRS) and lung transplantation (LTx) are the treatments of choice in selected patients with end-stage emphysema. Recently, the history of LVRS has been questioned due to reduced post-transplant survival. We aim to address this question by reviewing our experience, which is the largest single-centre series of LVRS followed by LTx. METHODS: We reviewed our prospectively recorded database in patients with emphysema undergoing LTx between 1993 and 2014...

OBJECTIVES: Lung volume reduction surgery (LVRS) has been demonstrated to provide symptomatic relief and improve lung function in patients with end-stage emphysema. The National Emphysema Treatment Trial specifically noted functional benefits in patients with predominantly upper lobe emphysema and demonstrated improvement in quality-of-life parameters, in patients with non-upper lobe emphysema and a low-baseline exercise capacity. We aimed to investigate whether physiological and health status benefits correlated with lower lobe LVRS...

The aim of this service improvement project was to gain understanding of the patient experience of lung volume reduction surgery (LVRS) and endobronchial valve (EBV) placement, from referral through to post-discharge care. Focus group interviews were carried out in two tertiary centres in London and Leicester, UK. Sixteen patients who had undergone lung volume reduction surgery (LVRS), endobronchial valve (EBV) placement, or both, were recruited. Prior to participation in each focus group, participants completed a questionnaire to guide and focus discussion...

Lung volume reduction surgery (LVRS) is an option for emphysematous patients who are awaiting lung transplantation. LVRS reduces nonfunctional portions of lung tissues and favors the compensatory lung growth (CLG) of the remaining lobes. This phenomenon diminishes dyspnea and improves both the respiratory mechanics and quality of life for the patients. An animal model of elastase-induced pulmonary emphysema was used to investigate the structural and functional lung response after LVRS. Bilobectomy was performed six weeks after elastase instillation...

Lung volume reduction surgery (LVRS) has been shown to be beneficial in patients with chronic obstructive pulmonary disease, but there is low uptake, partly due to perceived concerns of high operative mortality. We aimed to develop an individualised risk score following LVRS.This was a cohort study of patients undergoing LVRS. Factors independently predicting 90-day mortality and a risk prediction score were identified. Reliability of the score was tested using area under the receiver operating characteristic curve (AUROC)...

Unidirectional airway valves are devices used for the treatment of persistent air leaks (PALs) secondary to alveolar-pleural fistulas (APF) or bronchopleural fistulas (BPFs). These valves were originally developed as a non-surgical alternative to lung volume reduction surgery (LVRS) for patients with chronic obstructive pulmonary disease (COPD). Randomized trials investigating the use of valves for bronchoscopic LVRS did not lead to the Federal Drug Administration (FDA) approval, but stemming from these studies a Humanitarian Device Exemption (HDE) was granted to Spiration intrabronchial valves (IBVs) for the treatment of PALs...

Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease. Frequent pneumonias and exacerbations are known to accelerate its progression. We present a case of severe emphysema whose lung function paradoxically improved following recurrent pneumonia, without lung volume reduction surgery (LVRS). A 54-year-old female with severe COPD presented for LVRS evaluation. She was not a candidate for the surgery because of the unsuitable anatomic distribution of her emphysema. The patient experienced recurrent pneumonia over the years but her lung function and oxygen requirement showed marked improvement...

Lung volume reduction surgery (LVRS) and bronchoscopic lung volume reduction (bLVR) are palliative treatments aimed at reducing hyperinflation in advanced emphysema. Previous work has evaluated functional improvements and survival advantage for these techniques, although their effects on the micromechanical environment in the lung have yet to be determined. Here, we introduce a computational model to simulate a force-based destruction of elastic networks representing emphysema progression, which we use to track the response to lung volume reduction via LVRS and bLVR...

Squamous cell carcinoma of the vulva is predominantly a disease of the elderly, where the mainstay of treatment is radical surgery. Local vulval recurrence (LVR) is a significant problem for these patients, and the rates of recurrence have not improved over the last three decades. Disappointingly, we still lack an understanding of how LVRs develop, and the best approach to prevent and manage the condition. This review discusses recent insights into the key prognostic factors that influence the risk of recurrence, focusing on the role of tumour-adjacent non-neoplastic epithelial disorders, which are thought to play a causative role...

The aim of the present study was to investigate the feasibility and efficacy of staged bilateral single-port thoracoscopic lung volume reduction surgery (LVRS) for patients with chronic obstructive pulmonary emphysema (COPE). Eleven male patients with a mean age of 60.27±12.11 years with bilateral COPE and bullae were admitted to the Department of Thoracic Surgery, Xuzhou Central Hospital from January 2013 to June 2014. The patients underwent staged bilateral single-port thoracoscopic LVRS. The hyperinflated bullae were resected using endoscopic staplers (Endo-GIA), followed by continuous suture and biological glue for reinforcement of the margin...

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether potential surgical candidates for lung volume reduction surgery (LVRS), who have preoperative hypercapnia, should be excluded on this basis. Using the reported search, 45 papers were found, of which 14 represented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses were tabulated...

We recently identified a population of 10% of infants who respond with sub-protective antibody levels to most routine primary pediatric vaccinations due to altered innate and adaptive immune responses. We term these infants as low vaccine responders (LVRs). Here we report new data showing that TLR7/8 agonist - R848 stimulation of PBMCs of LVR infants elicit significantly lower IFN-α, IL-12p70 and IL-1β, while inducing higher levels of CCL5 (RANTES) compared to normal vaccine responder (NVR) infants.

BACKGROUND: Lung volume reduction surgery (LVRS) performed to treat patients with severe diffuse emphysema was reintroduced in the nineties. Lung volume reduction surgery aims to resect damaged emphysematous lung tissue, thereby increasing elastic properties of the lung. This treatment is hypothesised to improve long-term daily functioning and quality of life, although it may be costly and may be associated with risks of morbidity and mortality. Ten years have passed since the last version of this review was prepared, prompting us to perform an update...

In a number of large case series in the mid-1990s, lung volume reduction surgery (LVRS) was shown to reduce dyspnoea and improve pulmonary function and quality of life in patients with advanced pulmonary emphysema. The large randomised National Emphysema Treatment Trial (NETT) confirmed this in the early 2000s and also demonstrated that selected patients live longer after surgery. Patient selection is crucial to the success of the procedure and should be performed at a specialised experienced centre with a multidisciplinary team approach on emphysema treatment...

Bronchoscopic lung volume reduction (BLVR) is a minimally invasive treatment for severe emphysema, providing treatment options for patients who are unable to undergo lung volume reduction surgery (LVRS) or lung transplantation. Current BLVR techniques include bronchoscopic volume reduction with valve implants, use of a lung volume reduction coil (LVRC), bronchoscopic thermal vapor ablation (BTVA), biological lung volume reduction (BioLVR), and use of airway bypass stents (ABS). To date, several randomized controlled trials of these bronchoscopic therapies have been conducted in patients with emphysema, and bronchoscopic volume reduction with valve implants remains the best approach thus far...

Lung volume reduction surgery (LVRS) is an important treatment option for end-stage lung emphysema in carefully selected patients. Here, we first describe the application of low-flow venovenous extracorporeal CO2 removal (LFVV-ECCO2R) as bridge to LVRS in patients with end-stage lung emphysema experiencing severe hypercapnia caused by acute failure of the breathing pump. Between March and October 2015, n = 4 patients received single-site LFVV-ECCO2R as bridge to LVRS. Indication for extracorporeal lung support was severe hypercapnia with respiratory acidosis and acute breathing pump failure...
