Background: The role of the number of involved structures (NIS) in thymic epithelial tumors (TETs) has been investigated for inclusion in future staging systems, but large cohort results still are missing. This study aimed to analyze the prognostic role of NIS for patients included in the European Society of Thoracic Surgeons (ESTS) thymic database who underwent surgical resection., Methods: Clinical and pathologic data of patients from the ESTS thymic database who underwent surgery for TET from January 2000 to July 2019 with infiltration of surrounding structures were reviewed and analyzed. Patients' clinical data, tumor characteristics, and NIS were collected and correlated with CSS using Kaplan-Meier curves. The log-rank test was used to assess differences between subgroups. A multivariable model was built using logistic regression analysis., Results: The final analysis was performed on 303 patients. Histology showed thymoma for 216 patients (71.3%) and NET/thymic carcinoma [TC]) for 87 patients (28.7%). The most frequently infiltrated structures were the pleura (198 cases, 65.3%) and the pericardium in (185 cases, 61.1%), whereas lung was involved in 96 cases (31.7%), great vessels in 74 cases (24.4%), and the phrenic nerve in 31 cases (10.2%). Multiple structures (range, 2-7) were involved in 183 cases (60.4%). Recurrence resulted in the death of 46 patients. The CSS mortality rate was 89% at 5 years and 82% at 10 years. In the univariable analysis, the favorable prognostic factors were neoadjuvant therapy, Masaoka stage 3, absence of metastases, absence of myasthenia gravis, complete resection, thymoma histology, and no more than two NIS. Patients with more than two NIS presented with a significantly worse CSS than patients with no more than two NIS (CSS 5- and 10-year rates: 9.5% and 83.5% vs 93.2% and 91.2%, respectively; p = 0.04). The negative independent prognostic factors confirmed by the multivariable analysis were incomplete resection (hazard ratio [HR] 2.543; 95% confidence interval [CI] 1.010-6.407; p = 0.048) and more than two NIS (HR 1.395; 95% CI 1.021-1.905; p = 0.036)., Conclusions: The study showed that more than two involved structures are a negative independent prognostic factor in infiltrative thymic epithelial tumors that could be used for prognostic stratification., (© 2024.

Introduction: Thymomas are rare intrathoracic malignancies that can relapse after surgery. Whether or not Post-Operative RadioTherapy (PORT) should be delivered after surgery remains a major issue. RADIORYTHMIC is an ongoing, multicenter, randomized phase 3 trial addressing this question in patients with completely R0 resected Masaoka-Koga stage IIb/III thymoma. Experts in the field met to develop recommendations for PORT., Methods: A scientific committee from the RYTHMIC network identified key issues regarding the modalities of PORT in completely resected thymoma. A DELPHI method was used to question 24 national experts, with 115 questions regarding the following: (1) imaging techniques, (2) clinical target volume (CTV) and margins, (3) dose constraints to organs at risk, (4) dose and fractionation, and (5) follow-up and records. Consensus was defined when opinions reached more than or equal to 80% agreement., Results: We established the following recommendations: preoperative contrast-enhanced computed tomography (CT) scan is recommended (94% agreement); optimization of radiation delivery includes either a four-dimensional CT-based planning (82% agreement), a breath-holding inspiration breath-hold-based planning, or daily control CT imaging (81% agreement); imaging fusion based on cardiovascular structures of preoperative and planning CT scan is recommended (82% agreement); right coronary and left anterior descending coronary arteries should be delineated as cardiac substructures (88% agreement); rotational RCMI/volumetric modulated arc therapy is recommended (88% agreement); total dose is 50 Gy (81% agreement) with 1.8 to 2 Gy per fraction (94% agreement); cardiac evaluation and follow-up for patients with history of cardiovascular disease are recommended (88% agreement) with electrocardiogram and evaluation of left ventricular ejection fraction at 5 years and 10 years., Conclusion: This is the first consensus for PORT in thymoma. Implementation will help to harmonize practices., Competing Interests: Disclosure The authors have no conflict of interest to disclose concerning the current work., (Copyright © 2024 International Association for the Study of Lung Cancer.

Objectives: Lower bilobectomy (LBL) leaves a residual pleural space potentially associated with adverse postoperative outcomes. In selected patients, right sleeve lower lobectomy (RSLL) with anastomosis between the middle lobe bronchus and intermediate bronchus is feasible. The outcomes of RSLL and LBL have not been compared. The aim of this study was to compare post-operative and long-term outcomes of RSLL and LBL in patients with lung cancer., Methods: We retrospectively included patients managed by RSLL or LBL at our referral chest-surgery institution between 2001 and 2019. Post-operative complications and mortality were compared. Kaplan-Meier curves were plotted to compare overall and disease-free survival rates., Results: We identified 23 patients with RSLL and 96 with LBL. Postoperative mortality was 9 % after RSLL and 5 % after LBL (p = 0.41). Bronchial fistula developed in 3 (13 %) RSLL patients and 6 (6 %) LBL patients (p = 0.23). Pleural space complications were significantly less common after RSLL (4/23 [17 %] vs. 45/96 [47 %], p = 0.03). Long-term vital capacity was significantly higher in the RSLL group (91 % vs. 64 %, p < 0.01). Five-year survival did not differ significantly between groups (84 % vs. 72 %, p = 0.09)., Conclusions: RSLL was associated with similar postoperative mortality and long-term survival compared to LBL. However, pleural space complications were less common and lung function was better after RSLL than after LBL. When feasible, RSLL may deserve preference over LBL in patients with lung cancer managed at highly experienced centres., Competing Interests: Declaration of competing interest The other authors have no disclosure to declare for this work., (Copyright © 2024 Elsevier Ltd.

Background: Ultrasound has demonstrated its interest in the analysis of diaphragm function in patients with respiratory failure. The criteria used to diagnose hemidiaphragm paralysis are not well defined., Methods: The aim of this observational retrospective study was to describe the ultrasound findings in 103 patients with diaphragm paralysis, previously diagnosed by conventional methods after various circumstances such as trauma or surgery. The ultrasound study included the recording of excursions of both diaphragmatic domes and the measurement of inspiratory thickening., Results: On paralyzed hemidiaphragm, thickening was less than 20% in all patients during deep inspiration. Thinning was recorded in 53% of cases. In some cases, the recording of the thickening could be difficult. The study of motion during voluntary sniffing reported a paradoxical excursion in all but one patient. During quiet breathing, an absence of movement or a paradoxical displacement was observed. During deep inspiration, a paradoxical motion at the beginning of inspiration followed by a reestablishment of movement in the cranio-caudal direction was seen in 82% of cases. In some patients, there was a lack of movement followed, after an average delay of 0.4 s, by a cranio-caudal excursion. Finally, in 4 patients no displacement was recorded. Evidence of hyperactivity (increased inspiratory thickening and excursion) of contralateral non-paralyzed hemidiaphragm was observed., Conclusion: To accurately detect hemidiaphragm paralysis, it would be interesting to combine the ultrasound study of diaphragm excursion and thickening. The different profiles reported by our study must be known to avoid misinterpretation., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Boussuges, Fourdrain, Leone, Brioude, Menard, Zieleskiewicz, Delliaux, Gouitaa, Dutau and Brégeon.)

Importance: In minimally invasive thoracic surgery, paravertebral block (PVB) using ultrasound (US)-guided technique is an efficient postoperative analgesia. However, it is an operator-dependent process depending on experience and local resources. Because pain-control failure is highly detrimental, surgeons may consider other locoregional analgesic options., Objective: To demonstrate the noninferiority of PVB performed by surgeons under video-assisted thoracoscopic surgery (VATS), hereafter referred to as PVB-VATS, as the experimental group compared with PVB performed by anesthesiologists using US-guided technique (PVB-US) as the control group., Design, Setting, and Participants: In this single-center, noninferiority, patient-blinded, randomized clinical trial conducted from September 8, 2020, to December 8, 2021, patients older than 18 years who were undergoing a scheduled minimally invasive thoracic surgery with lung resection including video-assisted or robotic approaches were included. Exclusion criteria included scheduled open surgery, any antalgic World Health Organization level greater than 2 before surgery, or a medical history of homolateral thoracic surgery. Patients were randomly assigned (1:1) to an intervention group after general anesthesia. They received single-injection PVB before the first incision was made in the control group (PVB-US) or after 1 incision was made under thoracoscopic vision in the experimental group (PVB-VATS)., Interventions: PVB-VATS or PVB-US., Main Outcomes and Measures: The primary end point was mean 48-hour post-PVB opioid consumption considering a noninferiority range of less than 7.5 mg of opioid consumption between groups. Secondary outcomes included time of anesthesia, surgery, and operating room occupancy; 48-hour pain visual analog scale score at rest and while coughing; and 30-day postoperative complications., Results: A total of 196 patients were randomly assigned to intervention groups: 98 in the PVB-VATS group (mean [SD] age, 64.6 [9.5] years; 53 female [54.1%]) and 98 in the PVB-US group (mean [SD] age, 65.8 [11.5] years; 62 male [63.3%]). The mean (SD) of 48-hour opioid consumption in the PVB-VATS group (33.9 [19.8] mg; 95% CI, 30.0-37.9 mg) was noninferior to that measured in the PVB-US group (28.5 [18.2] mg; 95% CI, 24.8-32.2 mg; difference: -5.4 mg; 95% CI, -∞ to -0.93; noninferiority Welsh test, P ≤ .001). Pain score at rest and while coughing after surgery, overall time, and postoperative complications did not differ between groups., Conclusions and Relevance: PVB placed by a surgeon during thoracoscopy was noninferior to PVB placed by an anesthesiologist using ultrasonography before incision in terms of opioid consumption during the first 48 hours., Trial Registration: ClinicalTrials.gov Identifier: NCT04579276.

Objectives: A lung transplant is the final treatment option for end-stage lung disease. We evaluated the individual risk of 1-year mortality at each stage of the lung transplant process., Methods: This study was a retrospective analysis of patients undergoing bilateral lung transplants between January 2014 and December 2019 in 3 French academic centres. Patients were randomly divided into development and validation cohorts. Three multivariable logistic regression models of 1-year mortality were applied (i) at recipient registration, (ii) the graft allocation and (iii) after the operation. The 1-year mortality was predicted for individual patients assigned to 3 risk groups at time points A to C., Results: The study population consisted of 478 patients with a mean (standard deviation) age of 49.0 (14.3) years. The 1-year mortality rate was 23.0%. There were no significant differences in patient characteristics between the development (n = 319) and validation (n = 159) cohorts. The models analysed recipient, donor and intraoperative variables. The discriminatory power (area under the receiver operating characteristic curve) was 0.67 (0.62-0.73), 0.70 (0.63-0.77) and 0.82 (0.77-0.88), respectively, in the development cohort and 0.74 (0.64-0.85), 0.76 (0.66-0.86) and 0.87 (0.79 - 0.95), respectively, in the validation cohort. Survival rates were significantly different among the low- (< 15%), intermediate- (15%-45%) and high-risk (> 45%) groups in both cohorts., Conclusions: Risk prediction models allow estimation of the 1-year mortality risk of individual patients during the lung transplant process. These models may help caregivers identify high-risk patients at times A to C and reduce the risk at subsequent time points., (© The Author(s) 2023.

Primary ciliary dyskinesia, with or without situs abnormalities, is a rare lung disease that can lead to an irreversible lung damage that may progress to respiratory failure. Lung transplant can be considered in end-stage disease. This study describes the outcomes of the largest lung transplant population for PCD and for PCD with situs abnormalities, also identified as Kartagener's syndrome. Retrospectively collected data of 36 patients who underwent lung transplantation for PCD from 1995 to 2020 with or without SA as part of the European Society of Thoracic Surgeons Lung Transplantation Working Group on rare diseases. Primary outcomes of interest included survival and freedom from chronic lung allograft dysfunction. Secondary outcomes included primary graft dysfunction within 72 h and the rate of rejection ≥A2 within the first year. Among PCD recipients with and without SA, the mean overall and CLAD-free survival were 5.9 and 5.2 years with no significant differences between groups in terms of time to CLAD (HR: 0.92, 95% CI: 0.27-3.14, p = 0.894) or mortality (HR: 0.45, 95% CI: 0.14-1.43, p = 0.178). Postoperative rates of PGD were comparable between groups; rejection grades ≥A2 on first biopsy or within the first year was more common in patients with SA. This study provides a valuable insight on international practices of lung transplantation in patients with PCD. Lung transplantation is an acceptable treatment option in this population., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Marro, Leiva-Juárez, D’Ovidio, Chan, Van Raemdonck, Ceulemans, Moreno, Kindelan, Krueger, Koutsokera, Ehrsam, Inci, Yazicioglu, Yekeler, Boffini, Brioude, Thomas, Pizanis, Aigner, Schiavon, Rea, Anile, Venuta and Keshavjee.)

Objectives: The aim of this study was to describe the epidemiology of patients undergoing diagnostic and/or curative surgical pulmonary resections for lung opacities suspected of being localized primary lung cancers without preoperative tissue confirmation., Methods: We performed a single-centre retrospective study of a prospectively implemented institutional database of all patients who underwent pulmonary resection between January 2010 and December 2020. Patients were selected when surgery complied with the Fleischner society guidelines. We performed a multivariable logistic regression to determine the preoperative variables associated with malignancy., Results: Among 1392 patients, 213 (15.3%) had a final diagnosis of benignancy. We quantified futile parenchymal resections in 29 (2.1%) patients defined by an anatomical resection of >2 lung segments for benign lesions that did not modified the clinical management. Compared with patients with malignancies, patients with benignancies were younger (57.5 vs 63.9 years, P < 0.001), had lower preoperative risk profile (thoracoscore 0.4 vs 2.1, P < 0.001), had a higher proportion of wedge resection (50.7% vs 12.2%, P < 0.01) and experienced a lower burden of postoperative complication (Clavien-Dindo IV or V, 0.4% vs 5.6%, P < 0.001). Preoperative independent variables associated with malignancy were (adjusted odd ratio [95% confident interval]) age 1.02 [1.00; 1.04], smoking (year-pack) 1.005 (1.00; 1.01), history of cardiovascular disease 2.06 [1.30; 3.30], history of controlled cancer 2.74 [1.30; 6.88] and clinical N involvement 4.20 [1.11; 37.44]., Conclusions: Futile parenchymal lung resection for suspicious opacities without preoperative tissue diagnosis is rare (2.1%) while surgery for benign lesions represented 15.3% and has a satisfactory safety profile with very low postoperative morbi-mortality., (© The Author(s) 2023.

Background: Physiotherapy is a major cornerstone of enhanced rehabilitation after surgery (ERAS) and reduces the development of atelectasis after thoracic surgery. By initiating physiotherapy in the post-anaesthesia care unit (PACU), the aim was to evaluate whether the ultra-early initiation of rehabilitation (in the first hour following tracheal extubation) would improve the outcomes of patients undergoing elective thoracic surgery., Methods: A case-control study with a before-and-after design was conducted. From a historical control group, patients were paired at a 3:1 ratio with an intervention group. This group consisted of patients treated with the ultra-early rehabilitation programme after elective thoracic surgery (clear fluids, physiotherapy, and ambulation). The primary outcome was the incidence of postoperative atelectasis and/or pneumonia during the hospital stay., Results: After pairing, 675 patients were allocated to the historical control group and 225 patients to the intervention group. A significant decrease in the incidence of postoperative atelectasis and/or pneumonia was found in the latter (11.4 versus 6.7 per cent respectively; P = 0.042) and remained significant on multivariate analysis (OR 0.53, 95 per cent c.i. 0.26 to 0.98; P = 0.045). A subgroup analysis of the intervention group showed that early ambulation during the PACU stay was associated with a further significant decrease in the incidence of postoperative atelectasis and/or pneumonia (2.2 versus 9.5 per cent; P = 0.012)., Conclusions: Ultra-early rehabilitation in the PACU was associated with a decrease in the incidence of postoperative atelectasis and/or pneumonia after major elective thoracic surgery., (© The Author(s) 2022.

Objectives: Pulmonary retransplant (ReTx) is considered a controversial procedure. Despite literature reporting outcomes following ReTx, limited data exist in recipients bridged to their ReTx on extracorporeal life support (ECLS). The goal of this study was to investigate the outcomes of recipients bridged to a first-time ReTx by ECLS., Methods: We performed a retrospective multicentre cohort analysis from 10 centres in Europe, Asia and North America. The primary outcome was overall survival. Risk factors were analysed using Cox regression models., Results: ECLS as a bridge to a first-time ReTx was performed in 50 recipients (ECLS-ReTx). During the study period, 210 recipients underwent a first-time ReTx without bridging on ECLS (regular-ReTx) and 4959 recipients had a primary pulmonary transplant (index-Tx). The overall 1-year (55%) and 5-year (29%) survival was significantly worse for the ECLS-ReTx group.Compared to the index-Tx group, the mortality risk was significantly higher after ECLS-ReTx [hazard ratio 2.76 (95% confidence interval 1.94-3.91); P < 0.001] and regular-ReTx [hazard ratio 1.65 (95% confidence interval 1.36-2); P < 0.001].In multivariable analysis, recipient age ≥35 years, time interval <1 year from index-Tx, primary graft dysfunction as transplant indication, venoarterial-extracorporeal membrane oxygenation and Zurich donor score ≥4 points were significant risk factors for mortality in ECLS-ReTx recipients., Conclusions: Recipients for ECLS-ReTx should be carefully selected. Risk factors, such as recipient age, intertransplant interval, primary graft dysfunction as transplant indication and type of ECLS should be kept in mind before bridging these patients on ECLS to ReTx., (© The Author(s) 2021.

To identify predictors of postoperative urinary retention (POUR) following pulmonary resection. Retrospective chart review from a single academic institution of all patients who underwent pulmonary resection between June 2004 and January 2020. The surgical procedures consisted of pneumonectomy, lobectomy and sublobar resections. The primary outcome was occurrence of POUR within 30 days following surgery, defined as painful and palpable bladder, when the patient is unable to pass any urine, and requiring catheterization. A total of 6004 consecutive patients underwent pulmonary resection among which 306 pneumonectomies (5.1%), 3467 lobectomies (57.7%) and 2231 sublobar resection (37.2%). The surgical approach was a thoracotomy (n = 3546; 59.1%), a video-assisted [VATS] (n = 2075; 34.5%) or a robot-assisted thoracoscopy [RATS] (n = 383; 6.4%). POUR occurred in 301 cases (5%). On multivariable logistic regression analysis, male gender (OR 2.30 [1.70-3.17]; P < 0.001), age (OR 1.02 [1.01-1.03]; P < 0.001), benign prostatic hyperplasia (OR 7.08 [4.57-10.83]; P < 0.001), and COPD (OR 1.52 [1.13-2.01]; P = 0.004) were significant predictors of POUR. Conversely, VATS (OR 0.62 [0.46-0.83]; P = 0.001) had a protective effect on the occurrence of POUR. In a large single-center study, we disclosed significant clinical predictors of POUR after pulmonary resection, including age, sex, comorbidities and surgical approach. Prospective studies are necessary to evaluate the efficacy of chemoprophylaxis by perioperative α-blockers in order to prevent POUR., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Objectives: Resection of thymic tumours including the removal of both the tumour and the thymus gland (thymothymectomy; TT) is the procedure of choice and is recommended in most relevant articles in the literature. Nevertheless, in recent years, some authors have suggested that resection of the tumour (simple thymomectomy; ST) may suffice from an oncological standpoint in patients with early-stage thymoma who do not have myasthenia gravis (MG) (non-MG). The goal of our study was to compare the short- and long-term outcomes of ST versus TT in non-MG early-stage thymomas using the European Society of Thoracic Surgeons thymic database., Methods: A total of 498 non-MG patients with pathological stage I thymoma were included in the study. TT was performed in 466 (93.6%) of 498 patients who had surgery with curative intent; ST was done in 32 (6.4%). The completeness of resection, the rate of complications, the 30-day mortality, the overall recurrence and the freedom from recurrence were compared. We performed crude and propensity score-adjusted comparisons by surgical approach (ST vs TT)., Results: TT showed the same rate of postoperative complications, 30-day mortality and postoperative length of stay as ST. The 5-year overall survival rate was 89% in the TT group and 55% in the ST group. The 5-year freedom from recurrence was 96% in the TT group and 79% in the ST group., Conclusion: Patients with early-stage thymoma without MG who have a TT show significantly better freedom from recurrence than those who have an ST, without an increase in postoperative morbidity rate., (© The Author(s) 2021.

Background: Oesophageal pressure ( P oes ) is used to approximate pleural pressure ( P pl ) and therefore to estimate transpulmonary pressure ( P L ). We aimed to compare oesophageal and regional pleural pressures and to calculate transpulmonary pressures in a prospective physiological study on lung transplant recipients during their stay in the intensive care unit of a tertiary university hospital., Methods: Lung transplant recipients receiving invasive mechanical ventilation and monitored by oesophageal manometry and dependent and nondependent pleural catheters were investigated during the post-operative period. We performed simultaneous short-time measurements and recordings of oesophageal manometry and pleural pressures. Expiratory and inspiratory P L were computed by subtracting regional P pl or P oes from airway pressure; inspiratory P L was also calculated with the elastance ratio method., Results: 16 patients were included. Among them, 14 were analysed. Oesophageal pressures correlated with dependent and nondependent pleural pressures during expiration (R 2 =0.71, p=0.005 and R 2 =0.77, p=0.001, respectively) and during inspiration (R 2 =0.66 for both, p=0.01 and p=0.014, respectively). P L values calculated using P oes were close to those obtained from the dependent pleural catheter but higher than those obtained from the nondependent pleural catheter both during expiration and inspiration., Conclusions: In ventilated lung transplant recipients, oesophageal manometry is well correlated with pleural pressure. The absolute value of P oes is higher than P pl of nondependent lung regions and could therefore underestimate the highest level of lung stress in those at high risk of overinflation., Competing Interests: Conflict of interest: A.

Objective: We investigated on the benefit/risk ratio of surgery in octogenarians with early-stage non-small cell lung cancer (NSCLC)., Material and Methods: From 2005-2020, 100 octogenarians were operated on for a clinical stage IA to IIA NSCLC. All patients had undergone whole body PET -scan and brain imaging. Operability was assessed according to current guidelines regarding the cardiopulmonary function. Since 2015, patients followed a dedicated geriatric evaluation pathway. Minimally invasive approaches were used in 66 patients, and a thoracotomy in 34., Results: Clavien-Dindo grade ≥ 4 complications occurred in 15 patients within 90 days, including 7 fatalities. At multivariable analysis, the number of co-morbidities was their single independent prognosticator. Following resection, 24 patients met pathological criteria for adjuvant therapy among whom 3 (12.5 %) received platinum-based chemotherapy. Five-year survival rates were overall (OS) 47 ± 6.3 %, disease-free (DFS) 77.6 ± 5.1 %, and lung cancer-specific (CSS) 74.7 ± 6.3 %. Diabetes mellitus impaired significantly long-term outcomes in these 3 dimensions. OS was improved since the introduction of a dedicated geriatric assessment pathway (72.3 % vs. 6.4 %, P = 0.00002), and when minimally invasive techniques were used (42.3 % vs. 11.3 %; P = 0.02). CSS was improved by the performance of systematic lymphadenectomy (55.3 % vs. 26.9 %; P = 0.04). Multivariable and recursive partitioning analyses showed that a decision tree could be built to predict overall survival on the basis of diabetes mellitus, high co-morbidity index and low ppoDLCO values., Conclusions: The introduction of a dedicated geriatric assessment pathway to select octogenarians for lung cancer surgery was associated with OS values that are similar to outcomes in younger patients. The use of minimally invasive surgery and the performance of systematic lymphadenectomy were also associated with improved long-term survival. Octogenarians with multiple co-morbid conditions, diabetes mellitus, or low ppo DLCO values may be more appropriately treated with SBRT., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Objectives: Health care-associated infections (HAIs) are serious issues following lung cancer surgery, leading to an increased risk of morbidity and hospital cost burden. The aim of this study was to evaluate the impact on postoperative outcomes of a preoperative screening and decolonization strategy of nasal carriers for Staphylococcus aureus prior to lung cancer surgery., Methods: We performed a retrospective study comparing 2 cohorts of patients undergoing major lung resection: a control group of patients from the placebo arm of the randomized Clinical Study to Evaluate the Efficacy of Chlorhexidine Mouthwashes operated on between July 2012 and April 2015 without any nasopharyngeal screening (N = 224); an experimental group, with preoperative screening for S. aureus of nasal carriers and selective 5-day decolonization in positive carriers using mupirocin ointment between January 2017 and December 2017 (N = 310). The 2 groups were matched according to a propensity score analysis with 1:1 matching. The primary outcome was the rate of postoperative HAIs, and the secondary outcome was the need for postoperative mechanical ventilation after surgery., Results: After matching, 2 similar groups of 108 patients each were obtained. In the experimental group, 26 patients had positive results for nasal carriage, and a significant decrease was observed in the rate of overall postoperative HAIs [control n = 19, 17.6%; experimental group n = 9, 8.3%; P = 0.043; relative risk 0.47 (0.22-1)] and in the rate of postoperative mechanical ventilation [control n = 12, 11.1%; experimental group n = 4, 3.7%; P = 0.038; relative risk 0.33 (0.11-1)]. After logistic regression and multivariable analysis, screening of S. aureus nasal carriers reduced the rate of HAIs [odds ratio (OR) 0.29, 95% confidence interval (CI) 0.11-0.76; P = 0.01] and reduced the risk of the need for postoperative mechanical ventilation (OR 0.19, 95% CI 0.05-0.74; P = 0.02). There was no significant statistical difference between the 2 groups regarding the rate of postoperative S. aureus-associated infection (control group n = 6, 5.6%; experimental group n = 2, 1.9%; P = 0.28)., Conclusions: Identification of nasal carriers of S. aureus and selective decontamination using mupirocin appeared to have a beneficial effect on postoperative infectious events after lung resection surgery., (© The Author(s) 2019.

The first successful single-lung and double-lung transplantations were performed in the eighties. Since then both surgical and anesthesiological management have improved. The aim of this paper is to describe the surgical technique of lung transplantation: from the anesthesiological preparation, to the explantation and implantation of the lung grafts, and the preparation of the donor lungs. We will also describe the main surgical complications after lung transplantation and their management. Each step of the surgical procedure will be illustrated with photos and videos., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Stomach is the usual organ of choice for oesophageal replacement. Gastric pull-up is a standardized, fast and secure procedure, requiring only one anastomosis and usually performed with mini-invasive techniques. Colon is used when the stomach is not available, for tumours of the upper oesophagus or the hypopharynx, for benign or paediatric diseases. It is a complex surgery requiring a specific pre-operative management, three or four anastomoses, and a careful choice of the route of reconstruction. Early post-operative complications, such as anastomotic leakage, are frequent. Long-term outcomes are marked by strictures of the anastomosis and redundancy, but the reported quality of life of the patients is good. Eso-coloplasty remains a safe and feasible alternative to gastric pull-up for oesophageal replacement, for specific indications., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

A quarter of patients with clinical N1 (cN1) non-small cell lung cancer (NSCLC) based on positron emission tomography-computed tomography (PET-CT) imaging have occult mediastinal nodal involvement (N2 disease). In a prospective study, endosonography alone had an unsatisfactory sensitivity (38%) in detecting N2 disease. The current prospective multicentre trial investigated the sensitivity of preoperative mediastinal staging by video-assisted mediastinoscopy (VAM) or VAM-lymphadenectomy (VAMLA).Consecutive patients with operable and resectable (suspected) NSCLC and cN1 after PET-CT imaging underwent VAM(LA). The primary study outcome was sensitivity to detect N2 disease. Secondary endpoints were the prevalence of N2 disease, negative predictive value (NPV) and accuracy of VAM(LA).Out of 105 patients with cN1 on imaging, 26% eventually developed N2 disease. Invasive mediastinal staging with VAM(LA) had a sensitivity of 73% to detect N2 disease. The NPV was 92% and accuracy 93%. Median number of assessed lymph node stations during VAM(LA) was 4 (IQR 3-5), and in 96%, at least three stations were assessed.VAM(LA) has a satisfactory sensitivity of 73% to detect mediastinal nodal disease in cN1 lung cancer, and could be the technique of choice for pre-resection mediastinal lymph node assessment in this patient group with a one in four chance of occult-positive mediastinal nodes after negative PET-CT., Competing Interests: Conflict of interest: Disclosures can be found alongside this article at erj.ersjournals.com, (Copyright ©ERS 2017.)

Objectives: Surgery for thymic epithelial tumours (TETs) with pleural involvement is infrequently performed. Thus, the value of surgical therapy for primary or recurrent TETs with pleural involvement is not sufficiently defined yet., Methods: Twelve institutions contributed retrospective data on 152 patients undergoing surgery (1977-2014) on behalf of the ESTS Thymic Working group. Outcome measures included overall (OS), cause-specific (CSS) and disease-free (DFS) survival as well as freedom from recurrence (FFR)., Results: In 70.4% of cases, pleural involvement was present at the time of primary intervention, whereas 29.6% had surgery for recurrent disease involving the pleura. Pleural involvement resulted from thymomas (88.8%) and thymic carcinomas (11.2%). Forty extrapleural pneumonectomies (EPPs), 23 total pleurectomies (TPs), and 88 local pleurectomies (LPs) were performed (completeness of resection in 76.8%). OS for the entire patient population at 1, 3, 5 and 10 years was 96.4%, 91.0%, 87.2% and 62.7%, respectively. There was no statistically significant difference regarding FFR and OS for patients with local or advanced disease undergoing EPP, TP or LP. Thymic carcinomas in comparison with thymomas had a negative impact on OS [hazard ratio 6.506, P  = 0.002], CSS and FFR. Incomplete resections predicted worse OS [hazard ratio 6.696, P  = 0.003]., Conclusions: Complete resection remains the mainstay of treatment for TETs with pleural involvement. Study populations treated with EPP, TP and LP had similar survival that may be factual as observed, but in the presence of selection bias, we can further conclude from the results that EPP, TP and LP are equally effective procedures. Procedural choice depends upon the extent of tumour distribution. EPPs, TPs and LPs performed within a multimodality setting seem to be efficient procedures for local control of disease, as they yield excellent results regarding OS, DFS, CSS and FFR., (© The Author 2017.

Objective: Despite recent advances in imaging and core or endoscopic biopsies, a percentage of patients have a major lung resection without diagnosis. We aimed to assess the feasibility of a rapid tissue preparation/analysis to discriminate cancerous from non-cancerous lung tissue., Methods: Fresh sample preparations were analyzed with the Microflex LTTM MALDI-TOF analyzer. Each main reference spectra (MSP) was consecutively included in a database. After definitive pathological diagnosis, each MSP was labeled as either cancerous or non-cancerous (normal, inflammatory, infectious nodules). A strategy was constructed based on the number of concordant responses of a mass spectrometry scoring algorithm. A 3-step evaluation included an internal and blind validation of a preliminary database (n = 182 reference spectra from the 100 first patients), followed by validation on a whole cohort database (n = 300 reference spectra from 159 patients). Diagnostic performance indicators were calculated., Results: 127 cancerous and 173 non-cancerous samples (144 peripheral biopsies and 29 inflammatory or infectious lesions) were processed within 30 minutes after biopsy sampling. At the most discriminatory level, the samples were correctly classified with a sensitivity, specificity and global accuracy of 92.1%, 97.1% and 95%, respectively., Conclusions: The feasibility of rapid MALDI-TOF analysis, coupled with a very simple lung preparation procedure, appears promising and should be tested in several surgical settings where rapid on-site evaluation of abnormal tissue is required. In the operating room, it appears promising in case of tumors with an uncertain preoperative diagnosis and should be tested as a complementary approach to frozen-biopsy analysis.

Recently, tissue-based methods for proteomic analysis have been used in clinical research and appear reliable for digestive, brain, lymphomatous, and lung cancers classification. However simple, tissue-based methods that couple signal analysis to tissue imaging are time consuming. To assess the reliability of a method involving rapid tissue preparation and analysis to discriminate cancerous from non-cancerous tissues, we tested 141 lung cancer/non-tumor pairs and 8 unique lung cancer samples among the stored frozen samples of 138 patients operated on during 2012. Samples were crushed in water, and 1.5 µl was spotted onto a steel target for analysis with the Microflex LT analyzer (Bruker Daltonics). Spectra were analyzed using ClinProTools software. A set of samples was used to generate a random classification model on the basis of a list of discriminant peaks sorted with the k-nearest neighbor genetic algorithm. The rest of the samples (n = 43 cancerous and n = 41 non-tumoral) was used to verify the classification capability and calculate the diagnostic performance indices relative to the histological diagnosis. The analysis found 53 m/z valid peaks, 40 of which were significantly different between cancerous and non-tumoral samples. The selected genetic algorithm model identified 20 potential peaks from the training set and had 98.81% recognition capability and 89.17% positive predictive value. In the blinded set, this method accurately discriminated the two classes with a sensitivity of 86.7% and a specificity of 95.1% for the cancer tissues and a sensitivity of 87.8% and a specificity of 95.3% for the non-tumor tissues. The second model generated to discriminate primary lung cancer from metastases was of lower quality. The reliability of MALDI-ToF analysis coupled with a very simple lung preparation procedure appears promising and should be tested in the operating room on fresh samples coupled with the pathological examination.

Bilateral lung transplantation was performed in a 52-year old man with end-stage Kartagener's syndrome. A postimplantation right lower lobectomy was required for volume reduction and dextrocardia. A bronchial fistula developed with an intractable colonized residual pleural cavity. Closure was obtained successfully with multiple-stage procedures including decortication, muscle flap and an open-window thoracostomy without modification of the immunosuppressive protocol.

Objectives: Recent studies have suggested that postoperative complications could have a potential negative effect on long-term outcome after oesophagectomy for cancer. Because respiratory failures represent the most frequent postoperative complication, we have investigated the prognostic impact of these complications on disease-free survival (DFS)., Methods: From a prospective single-institution database of 405 consecutive patients who underwent transthoracic oesophagectomy for cancer, we retrospectively analysed medical charts of all patients with microscopically complete resection (R0, n = 384 patients). Complications were graded according to the modified Clavien classification. Respiratory complications were defined as atelectasis, pneumonia or acute respiratory distress syndrome in the absence of early surgical complications. Patients with grade 5 (postoperative mortality, n = 43, 11%) were excluded from the analysis. The remaining 341 patients were analysed for estimation of DFS according to the Kaplan-Meier method. Logistic regression analysis was conducted to discriminate predictive factors affecting DFS., Results: According to the modified Clavien classification, postoperative complications rates were grade 0: 147 (44%), grade 1: 7 (2%), grade 2: 56 (16%), grade 3: 69 (20%) and grade 4: 62 (18%). Five-year DFS rates were not significantly different between grade 0 (no complication, 38%, n = 147) and other grades (grade 1, 2, 3 and 4 (64, 45, 56 and 48%, respectively)). Respiratory complications occurred in 107 patients (31%) and the 5-year DFS in this subgroup was 47% compared with 38% observed in grade 0 patients (P = 0.75). Clavien classification and respiratory complications did not come out in the univariate analysis of factors affecting DFS. On logistic regression, only two variables affected DFS: c-N stage and extracapular lymph node involvement., Conclusions: When postoperative mortality is excluded, postoperative complications do not affect DFS in patients with complete resection. This deserves substantial information regarding the prognosis of subgroup of patients in critical situations where incrementing intensive care is debated.
