Abstract
Endobronchial coil treatment (ECT) is a minimally invasive procedure developed for palliative care of patients with severe emphysema. ECT has demonstrated a decrease in hyperinflation, an improvement in quality of life, and an acceptable safety profile in randomized controlled trials (RCTs). Because alpha-1 antitrypsin deficiency (AATD) is a classical exclusion criterion in RCTs, there is no available data for ECT in AATD. In this post hoc analysis of the REVOLENS study (Réduction volumique endobronchique par spirales; ClinicalTrials.gov Identifier: NCT01822795), a multicenter 1:1 RCT which compared bilateral ECT with usual care in severe emphysema, we analyzed the efficacy and safety results at 1 year in six patients with AATD (five males, one female; mean age: 52±9 years) who underwent ECT. A significant decrease in hyperinflation (0.35 L decrease in residual volume [RV]) was observed in four out of six patients at 6 months and three out of six patients at 12 months, and an improvement in quality of life (improvement of 4 points in the St George’s Respiratory Questionnaire [SGRQ]) was observed in four out of six patients at both 6 and 12 months. Efficacy results at 6 and 12 months from the six AATD patients were compared with 84 non-AATD patients who underwent ECT, and no statistically significant differences were found for FEV1, RV, 6MWT score and SGRQ score. Respiratory-related serious adverse event was limited to pneumonia in one AATD patient at 1 year post-ECT. This post hoc study suggests that AATD patients may have similar efficacy and safety outcomes at 1 year as non-AATD patients. Because of the paucity of available data, appropriately powered studies are needed to determine the effects of ECT in AATD.

Abstract
INTRODUCTION Benign laryngotracheal stenosis is a rare pathology with multiple etiologies, the management of which is complex. This is because of the configuration and proximity of the larynx and the difficulty with surgical approaches, which are potentially mutilating, especially for the management of a benign disease. When surgery is challenging, iterative dilatations of the stricture or the fashioning of a definitive tracheotomy are therapeutic alternatives. Advances in rigid bronchoscopy and the evolution of prosthetic silicone material allow a new approach in the management of benign laryngotracheal stenosis, by placing flexible silicone prostheses which cover all the stenosis from the arytenoids to the trachea. This preliminary work aims to evaluate the feasibility, effectiveness, tolerance and complications of the implementation of this type of prosthesis. PATIENTS AND METHODS This is a retrospective single-centre study which analyzed the records of patients with symptomatic benign laryngotracheal stenosis who underwent placement of a transcordial prosthesis over a period of three years. The prosthesis used, inserted under general anesthesia during a rigid tube interventional bronchoscopy, was either a straight silicone prosthesis or a Montgomery T-tube for those with a pre-existing tracheotomy. RESULTS Six patients were included. Five are still alive, one patient died from a cause unrelated to the placement of the prosthesis. Four have no tracheostomy and two now have no transcordal prosthesis. The data collected on tolerance found, for three patients, two cases of minor aspiration and one case of transient cough. All patients had whispered voice dysphonia. We did not observe prosthesis migration or obstruction. CONCLUSION These preliminary results are encouraging. Transcordal prostheses in benign laryngotracheal stenosis have a complementary or alternative role compared to surgery with a palliative or even curative objective.

Abstract
BACKGROUND Nonmalignant esophago-respiratory fistulas (ERF) are frightening clinical situations, involving surgery with high morbi-mortality rate. We described the endoscopic management of benign ERF. The aim of the study was to describe outcomes of endoscopic treatment of nonmalignant ERF and to analyze factors associated with its success. METHODS This is a retrospective study involving patients managed for benign ERF in our center between 2012 and 2016. The ERFs were classified into three groups of sizes: (I) punctiform, (II) medium, and (III) large. The primary aim was to document the endoscopic success (= fistula's healing after 6 months). The secondary objectives were characteristics of endoscopic treatment, the functional success and death, and identifying factors associated with success and death. RESULTS 22 patients were included. The etiologies of ERF were surgery in 12 patients, esophageal dilatation in 3, invasive ventilation in 3, radiation therapy in 2, and tracheostomy in 2. Ninety-three procedures were performed (mean of number: 4.2 ± 4.5/patient). Twenty-one patients had stent placement, eight over-the-scope clips (OTSC), and seven a combined therapy. The endoscopic success rate was 45.5% (n = 10; 67% in punctiform, 50% in medium, and 14% in large ERF), and the functional success was 55% (n = 12). Serious adverse events occurred in 9 patients (40.9%). Six patients died (27%). The persistence of the orifice after 6 months of endoscopic treatment was associated with failure (OR 44; IC95: 3.38-573.4; p = 0.004 multivariate analysis). The orifice's size was associated with mortality [71% of death if large fistulas (p = 0.001) univariate analysis]. CONCLUSION Endoscopic treatment of ERF leads to 45.5% of successful endoscopic closure and 55.5% of functional success, depending on fistula's orifice size. After 6 months without healing, the chances for success dramatically decrease.

Abstract
IMPORTANCE Airway transplantation could be an option for patients with proximal lung tumor or with end-stage tracheobronchial disease. New methods for airway transplantation remain highly controversial. OBJECTIVE To establish the feasibility of airway bioengineering using a technique based on the implantation of stented aortic matrices. DESIGN, SETTING, AND PARTICIPANTS Uncontrolled single-center cohort study including 20 patients with end-stage tracheal lesions or with proximal lung tumors requiring a pneumonectomy. The study was conducted in Paris, France, from October 2009 through February 2017; final follow-up for all patients occurred on November 2, 2017. EXPOSURES Radical resection of the lesions was performed using standard surgical techniques. After resection, airway reconstruction was performed using a human cryopreserved (-80°C) aortic allograft, which was not matched by the ABO and leukocyte antigen systems. To prevent airway collapse, a custom-made stent was inserted into the allograft. In patients with proximal lung tumors, the lung-sparing intervention of bronchial transplantation was used. MAIN OUTCOMES AND MEASURES The primary outcome was 90-day mortality. The secondary outcome was 90-day morbidity. RESULTS Twenty patients were included in the study (mean age, 54.9 years; age range, 24-79 years; 13 men [65%]). Thirteen patients underwent tracheal (n = 5), bronchial (n = 7), or carinal (n = 1) transplantation. Airway transplantation was not performed in 7 patients for the following reasons: medical contraindication (n = 1), unavoidable pneumonectomy (n = 1), exploratory thoracotomy only (n = 2), and a lobectomy or bilobectomy was possible (n = 3). Among the 20 patients initially included, the overall 90-day mortality rate was 5% (1 patient underwent a carinal transplantation and died). No mortality at 90 days was observed among patients who underwent tracheal or bronchial reconstruction. Among the 13 patients who underwent airway transplantation, major 90-day morbidity events occurred in 4 (30.8%) and included laryngeal edema, acute lung edema, acute respiratory distress syndrome, and atrial fibrillation. There was no adverse event directly related to the surgical technique. Stent removal was performed at a postoperative mean of 18.2 months. At a median follow-up of 3 years 11 months, 10 of the 13 patients (76.9%) were alive. Of these 10 patients, 8 (80%) breathed normally through newly formed airways after stent removal. Regeneration of epithelium and de novo generation of cartilage were observed within aortic matrices from recipient cells. CONCLUSIONS AND RELEVANCE In this uncontrolled study, airway bioengineering using stented aortic matrices demonstrated feasibility for complex tracheal and bronchial reconstruction. Further research is needed to assess efficacy and safety. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01331863.

Abstract
Wstęp: Proteinoza pęcherzyków płucnych (PAP, pulmonary alveolar proteinosis) to rzadka choroba płuc. W populacji irańskiej nie analizowano nigdy skuteczności płukania całego płuca (WLL, whole-lung lavage) jako leczenia PAP. Z tego powodu oceniono charakterystykę PAP, a także skuteczność WLL w tej rzadkiej chorobie. Niniejsze badanie miało na celu analizę cech demograficznych, obrazu klinicznego i wyników leczenie tej choroby u irańskich pacjentów z PAP. Materiał i metody: Zgromadzono dane 45 pacjentów z pewnym rozpoznaniem PAP, regularnie obserwowanych od marca 2004 do marca 2015 roku w irańskim szpitalu referencyjnym. Skuteczność WLL oceniano, porównując parametry spirometryczne, gazometrii krwi tętniczej oraz testu 6-minutowego marszu (6MWT, 6 minute walk test) przed i po wykonaniu wszystkich zabiegów płukania płuca. Wyniki: Średni wiek w momencie rozpoznania choroby wynosił 30.33 ± 14.56 roku. U czterech pacjentów (8.8%) występowało niemasywne krwioplucie, u trzech (6.6%) współistniała gruźlica płuc. Biopsja przezoskrzelowa płuca i płukanie oskrzelowo- -pęcherzykowe w 71.1% przypadków były wystarczającymi badaniami do postawienia rozpoznania. Wyniki spirometryczne, parametry gazometrii krwi tętniczej i 6MWD poprawiły się znamiennie po przeprowadzeniu wszystkich zabiegów płukania płuca. Czterech pacjentów (8.8%) zmarło z powodu niewydolności oddechowej. Jedyną zmienną mogącą przewidzieć niepowodzenie leczenia było występowanie krwioplucia w wywiadzie chorobowym. Wnioski: W badaniu wykazano, że WLL jest leczeniem skutecznym u pacjentów z PAP. Krwioplucie było niezależnym czynnikiem predykcyjnym niepowodzenia leczenia.

Abstract
BACKGROUND The REVOLENS study compared lung volume reduction coil treatment to usual care in patients with severe emphysema at 1 year, resulting in improved quality-adjusted life-year (QALY) and higher costs. Durability of the coil treatment benefit and its cost-effectiveness at 2 years are now assessed. METHODS After one year, the REVOLENS trial's usual care group patients received coil treatment (second-line coil treatment group). Costs and QALYs were assessed in both arms at 2 years and an incremental cost-effectiveness ratio in cost per QALY gained was calculated. The uncertainty of the results was estimated by probabilistic bootstrapping. RESULTS The average cost of coil treatment in both groups was estimated at €24,356. The average total cost at 2 years was €9655 higher in the first-line coil treatment group (p = 0.07) and the difference in QALY between the two groups was 0.127 (p = 0.12) in favor of first-line coil treatment group. The 2-year incremental cost-effectiveness ratio (ICER) was €75,978 / QALY. The scatter plot of the probabilistic bootstrapping had 92% of the replications in the top right-hand quadrant. CONCLUSION First-line coil treatment was more expensive but also more effective than second-line coil treatment at 2 years, with a 2-year ICER of €75,978 / QALY.

Abstract
BACKGROUND Chest ultrasound (CUS) is the gold standard to detect pleural adhesions before pleural maneuvers. However, the CUS technique is not available in all countries where the assessment is only based on clinical examination and chest radiography. OBJECTIVE To assess the value of lateral decubitus chest radiography (LDCR) to detect pleural adhesions. METHODS Consecutive patients with pleural effusions undergoing LCDR followed by medical thoracoscopy the day after were identified from an institutional database. The diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for LDCR were calculated. RESULTS Eighty-six patients were included in the study. The sensitivity, specificity, PPV, and NPV of LDCR for the presence of adhesions taking into account the shape of the horizontal level were 71.2% (56.7-82.5), 44.1% (27.6-61.9), 66.1% (52.1-77.8), and 50% (31.7-68.3), respectively. The accuracy to predict pleural adhesions for the sign "incomplete horizontal level" was 60.5 (49.3-70.7). The accuracy to predict pleural adhesions in case of irregular aspect of the horizontal level was 53.5 (42.5-64.2). CONCLUSIONS The accuracy of LDCR for the detection of pleural adhesions is low in patients with pleural effusion and LDCR is not sufficient before pleural maneuvers. This has to be taken into account in countries with a high prevalence of pleural tuberculosis which usually lead to loculated pleural effusions. CUS has to be urgently included in dedicated educational programs in these areas in order to decrease the complications related to unexpected pleural adhesions and achieve better planning for the management of pleural effusions.

Abstract
BACKGROUND Benign stenosis involving laryngeal and upper tracheal structures represents a therapeutic challenge. Open surgery and endoscopic management have to be discussed by a multidisciplinary board in order to evaluate the risk and benefit for each patient. OBJECTIVE The objective of this retrospective study was to report the experience of two French centers with transcordal silicone stents (TSS) in the endoscopic management of benign laryngotracheal stenosis (BLTS) in adults, with focus on efficacy, safety, and tolerability. METHODS We performed a retrospective chart review of all cases of BLTS treated with TSS between January 2001 and June 2017 at two tertiary centers in France: the Centre Hospitalier Régional Universitaire de Strasbourg and the Hôpital Nord de Marseille. RESULTS A total of 17 patients were included. Eleven had a tracheostomy at initial management which consisted of 8 T-tubes and 9 strictly endoluminal stents placements. The main complications were minor aspirations in 5 patients (29%), granulation in 3 patients (18%), migration in 2 patients (12%), and severe dysphonia in 3 patients (18%). After a mean duration of 18.3 months, 11 patients (65%) had had their TSS definitely removed, 13 patients were tracheostomy free (76%), and a TSS remained in place in 4 patients (24%). CONCLUSIONS Adult BLTS treatment with TSS placement is associated with low morbidity and excellent clinical outcomes, with a large proportion of patients free of airway instrumentation on long-term follow-up.

Abstract
Hemoptysis is a frequent manifestation of a wide variety of diseases, with mild to life-threatening presentations. The diagnostic workup and the management of severe hemoptysis are often challenging. Advances in endoscopic techniques have led to different new therapeutic approaches. Cold saline, vasoconstrictive and antifibrinolytic agents, oxidized regenerated cellulose, biocompatible glue, laser photocoagulation, argon plasma coagulation, and endobronchial stents and valves are amongst the tools available to the bronchoscopist. In this article, we review the evidence regarding the definition, etiology, diagnostic modalities, and treatment of severe hemoptysis in the modern era with emphasis on bronchoscopic techniques.

Abstract
Stent placement has been established as a standard procedure for treating airway obstructions. Other indications are localized malacias and fistulas. Though many different stents with various diameters and lengths are available, the shapes are hardly ever ideal because of the distorted anatomy in patients with diseased airways. There are technical and legal limitations for customizing purchased airway stents. Individually tailored stents would be preferable. New techniques of additive manufacturing such as 3D printing make it possible to produce optimized stents for a particular patient. Using CT data and bronchoscopic images, stents can be constructed that match a particular anatomical situation and apply the optimized expansion force. We give an overview of the currently available manufacturing techniques for polymeric stents and report about our own experience. Direct on-site printing of polyurethane stents in a hospital and printing individual extrusion molds for silicone stents in a certified cleanroom are both feasible. Furthermore, there are promising attempts of combining mechanically customized stents with surface modifications, drug-eluting features, biodegradability, and time-dependent adaptation (4D printing). Truly optimized airway stents with the potential of solving the well-known stent problems such as granulation tissue formation, remodeling, mucostasis, and infections are in reach. The technical hurdles are probably easier to overcome than the legal constraints. The legal situations are discussed from a physician's and a manufacturer's perspective.

Low lamin A expression in lung adenocarcinoma cells from pleural effusions is a pejorative factor associated with high number of metastatic sites and poor Performance status.

Abstract
The type V intermediate filament lamins are the principal components of the nuclear matrix, including the nuclear lamina. Lamins are divided into A-type and B-type, which are encoded by three genes, LMNA, LMNB1, and LMNB2. The alternative splicing of LMNA produces two major A-type lamins, lamin A and lamin C. Previous studies have suggested that lamins are involved in cancer development and progression. A-type lamins have been proposed as biomarkers for cancer diagnosis, prognosis, and/or follow-up. The aim of the present study was to investigate lamins in cancer cells from metastatic pleural effusions using immunofluorescence, western blotting, and flow cytometry. In a sub-group of lung adenocarcinomas, we found reduced expression of lamin A but not of lamin C. The reduction in lamin A expression was correlated with the loss of epithelial membrane antigen (EMA)/MUC-1, an epithelial marker that is involved in the epithelial to mesenchymal transition (EMT). Finally, the lamin A expression was inversely correlated with the number of metastatic sites and the WHO Performance status, and association of pleural, bone and lung metastatic localizations was more frequent when lamin A expression was reduced. In conclusion, low lamin A but not lamin C expression in pleural metastatic cells could represent a major actor in the development of metastasis, associated with EMT and could account for a pejorative factor correlated with a poor Performance status.

Abstract
Although endobronchial coils for the treatment of severe emphysema are associated with an acceptable safety profile, adverse events such as pneumothorax and thoracic pain may occur. The coils are indicated as a permanent implant and are deemed very difficult to remove. We describe the first successful removal of two coils 10 months after placement in a patient who experienced persistent thoracic pain. This case report highlights that very distal (subpleural) coil placement may induce pneumothorax and subsequent thoracic pain and that nonsurgical removal of coils up to 10 months after implantation is feasible.

Respiration 2017; 93:430-435. [PMID: 28448981 DOI: 10.1159/000472155] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2016] [Accepted: 03/23/2017] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND The use of self-expandable metallic stents (SEMS) in benign airway disease was the object of a boxed warning from the United States Food and Drug Administration in 2005 due to the risk of stent-related complications and difficulties associated with their removal. Third-generation fully covered SEMS have been commercialized since this warning and theoretically should not present the same difficulties associated with removal as they cannot become embedded in the airway mucosa. OBJECTIVES We aimed to examine the safety and efficacy of a specific third-generation SEMS, the Silmet stent. METHODS We reviewed the records of all patients treated for benign airway stenosis with third-generation Silmet SEMS from January 2011 to December 2015 at the North Hospital of Marseilles, France. RESULTS Forty SEMS were inserted in 30 patients over this period. Twenty (50.0%) stents were removed because of stent-related complications after a median of 77.0 ± 96.6 days (migration 32.5%, granulation tissue formation 7.5%, subjective intolerance 5.0%, mucus plugging 2.5%, laryngeal edema 2.5%). There were no cases of stent-related mortality. All complications were managed successfully endoscopically. Thirty-six stents (90.0%) were removed successfully after a median of 122.0 ± 113.2 days without any complications. The clinical success rate of stent treatment was 40.7%. CONCLUSION Third-generation SEMS are a safe treatment option for complex benign airway stenosis, but complications requiring stent removal are frequent. Further studies are needed to compare the performance of third-generation SEMS and silicone stents in benign airway stenosis.
