Abstract
Ultrasound-guided needle aspiration via the esophagus using the endobronchial endoscope (EUS-B-FNA) is increasingly being performed by the pulmonologist for the diagnosis of lung cancer, but we have little experience and data available in the literature especially with respect to staging of the disease. We present 2 cases of EUS-B-guided aspiration of malignant pericardial effusion performed in the same setting as bronchoscopy and endobronchial ultrasound. No complications were observed. We conclude that EUS-B-FNA may be safe and efficacious in the evaluation of pericardial effusion during lung cancer workup. Thus, EUS-B-FNA may save time in the diagnostic workup, improve cancer staging, and prevent transthoracic pericardiocentesis.

Abstract
Silicone from ruptured breast implants can cause lung symptoms mimicking cancer. The diagnosis may be established by transbronchial lung biopsy or surgery. We report a case of asymptomatic silicone induced granulomatous reaction in the lungs and mediastinal lymph nodes diagnosed with EBUS-TBNA. We conclude that this differential diagnosis should be kept in mind even in an asymptomatic patients and that EBUS-TBNA should be considered.

Abstract
Medical thoracoscopy allows the respiratory physician access to inspection and biopsy of the pleura. The method has several names, such as pleuroscopy, non-intubated thoracoscopy and exploratory thoracoscopy, all of which cover the same procedure. The main indication for medical thoracoscopy is the diagnosis of recurrent pleural effusion, where pleural biopsy is needed. Medical thoracoscopy differs from thoracic surgical surgery as patients are sedated rather than in general anaesthesia. This is a review of the state of the art of pulmonological investigations of recurrent pleural effusion and the important role of medical thoracoscopy.

Abstract
Background Several studies have reported the efficacy of esophageal ultrasound-guided fine needle aspiration (EUS-FNA) for the detection of metastases in the left adrenal gland (LAG) in patients with lung cancer. Currently we have only limited evidence based on small studies on the usefulness of EUS-B [endobronchial ultrasound (EBUS) scope into the esophagus] to provide tissue proof of suspected LAG metastases. The objectives of this study are to investigate feasibility, safety and diagnostic yield of EUS-B-FNA in LAG analysis in patients with proven or suspected lung cancer. Methods In two Danish hospitals, a systematic search in the electronic database for patients who underwent EUS-B-FNA of the LAG for suspected or proven lung cancer was performed retrospectively between January 1st, 2015 and December 31st, 2017. Computed tomography (CT), positron emission tomography-CT, endoscopy, pathology and follow-up data were acquired. Results One hundred and thirty-five patients were included; the prevalence of biopsy proven LAG malignancy was 30% (40/135). A total of 87% (117/135) of EUS-B-FNA samples were adequate (i.e., containing adrenal or malignant cells). No complications were observed. Conclusions We present the largest cohort of patients ever reported showing that EUS-B-FNA of the LAG is a safe and feasible procedure and should therefore be used for staging purposes in patients with lung cancer and a suspicious LAG.

Abstract
Flexible bronchoscopy and endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) are the pulmonologists´ basic procedures for the biopsy of suspicious lung lesions. If inconclusive, other guiding-modalities for tissue sampling are needed, computed tomography performed by a radiologist, or – if available – radial EBUS or electromagnetic navigation biopsy. We wanted to investigate if same-day X-ray fluoroscopy-guided transthoracic fine-needle aspiration biopsy (F-TTNAB) performed by the pulmonologist immediately after bronchoscopy and EBUS is a feasible alternative. We retrospectively identified consecutive patients in whom F-TTNAB followed a bronchoscopy and EBUS in the same séance. Patients in whom the suspicion of malignancy was invalidated after complete work up were followed for six months to identify false-negative cases. In total 125 patients underwent triple approach (bronchoscopy, EBUS and F-TTNAB) during the same séance. Malignancy was diagnosed in 86 (69%), and 77 of these (90%) were primary lung cancers. The diagnostic yield of F-TTNAB for malignancy was 77%, and sensitivity was 90%. Pneumothorax occurred in 35 (28%) patients, and was administered with pleural drainage in 22 (18% of all patients). No cases of prolonged haemoptysis were observed. The risk of pneumothorax differed insignificantly with lesion size ≤2.0 cm (27%) versus >2.0 cm (29%). We conclude that it is feasible for pulmonologist to perform F-TTNAB immediately after endoscopy as a combined triple approach in a fast-track workup of suspected lung cancer.

Abstract
Background The use of the endobronchial ultrasound (EBUS) scope in the oesophagus, the so-called EUS-B procedure, for the diagnosis and staging of lung cancer is quickly gaining ground. Case presentation We here present a case demonstrating that EUS-B guided aspiration of intraperitoneal fluid (ascites) is possible. This has never been described before. The procedure was performed with the use of a 22 G needle in a 71 years old woman suspected of lung cancer. No complications were seen. Conclusion We hereby demonstrate that EUS-B fine needle aspiration from ascites fluid is feasible and appears to be safe.

Abstract
BACKGROUND In patients with suspected or proven lung cancer, assessment of regional nodal and distant metastases is key before treatment planning. By introducing the endobronchial ultrasound (EBUS)-guided scope into the esophagus and stomach (EUS-B), liver lesions and celiac nodes can be visualized. To date, the utility of EUS-B in diagnosing liver lesions and retroperitoneal lymph nodes is unknown. OBJECTIVES To assess the feasibility, safety, and diagnostic yield of sampling of liver lesions and retroperitoneal nodes by EUS-B fine-needle aspiration (FNA) in a lung cancer staging setting. METHOD Consecutive patients suspected of lung cancer in 2 Danish centers between 1 January 2015 and 31 December 2017 were included retrospectively when a lesion in the liver or a retroperitoneal lymph node was visualized and biopsied with EUS-B-FNA. RESULTS 23 left liver lobe lesions and 19 retroperitoneal lymph nodes were sampled by EUS-B-FNA. Sensitivity and diagnostic yield of sampled liver lesions were 86 and 83%, respectively. In 19/23 patients, there was a cytopathological diagnosis of malignancy. Sensitivity and diagnostic yield from retroperitoneal lymph node samples were 83 and 63%, respectively. In 10/19 patients, the diagnosis was malignancy. No complications were observed. CONCLUSION EUS-B-FNA enables safe sampling of left liver lobe lesions and retroperitoneal lymph nodes. EUS-B should be considered as a minimally invasive technique to provide tissue proof of distant metastases lung cancer patients.

Abstract
Background The guidelines from the British Thoracic Society (BTS) regarding the investigation of unilateral pleural effusions recommend computed tomography (CT) in exudates. We decided to investigate if clinicians follow BTS guidelines' recommendations with respect to CT in patients with unilateral pleural effusions. Secondly, to investigate the diagnostic consequences of following and not following this recommendation. Methods The study was a retrospective, non-randomized study including consecutive patients referred to our tertiary centers in 2013-2016 because of unilateral pleural effusion. Patients undergoing chest CT for unilateral pleural effusion of unknown cause after thoracentesis and chest X-ray were included. Patients were categorized as having pleural exudates or transudates, according to Light's criteria, if applicable. We registered use of CT, and calculated diagnostic values. Results In total, 323 of the 465 included patients underwent CT (69%). CT was performed in the majority of patients not having an exudate (transudates: n=40; 54%; Light's criteria not assessed: n=111; 67%). 18F-FDG positron emission tomography (PET)/CT without prior CT was performed in 32 patients with an exudate (58%). The sensitivity of a non-guideline supported CT (70%) was significantly higher compared to a guideline supported CT (47%), P value <0.045. The post-test probability of a positive guideline-supported CT [likelihood ratio (LR) positive 3.26] for a later diagnosis of thoracic malignancy increased the probability from 25% to 52%. A negative CT (LR negative 0.62) decreased the probability to 17%. For a non-guideline-supported CT the numbers were (LR positive 3.42) 53% and (LR negative 0.38) 11%, respectively. Conclusions Clinicians appear not to follow BTS guidelines when deciding to perform chest CT. The relevance of this deviation is supported by the superior sensitivity of CT non-guideline supported CT. Overall, CT is associated with suboptimal sensitivity and negative predictive values for the diagnosis of thoracic malignancy.

Abstract
The scientific background in expert-opinion papers for recommending Computed Tomography (CT) in unilateral pleural exudates is based on studies including patients with other findings than unilateral pleural effusions or selected patients undergoing thoracoscopy. Therefore, we performed a systematic review investigating the sensitivity of CT for predicting malignancy in patients with unilateral, non-transudative, pleural effusions. A search strategy was developed with the assistance of a medical information specialist at our university library. We searched PubMed/MEDLINE, EMBASE and Cochrane Library, ClinicalTrials.gov and articles citing the included studies. No date restrictions were applied (the first included paper was published in 2001 (1)), and only literature in English was included. We used the Quality Assessment of Diagnostic Accuracy Studies 2 for bias assessment. We registered the protocol at PROSPERO (CRD42018094830). Five studies were included, two prospective and three retrospective, all performed in Western Europe. No study reported diagnostic values for patients with unilateral, non-transudative pleural effusions only; one study did for unilateral pleural effusions. In the remaining studies, most patients had unilateral effusions and non-transudative effusions. Patients were primarily males and >70 years. All but one study found a high incidence of malignancy, dominated by malignant pleural mesothelioma. All studies were limited by risk of bias and applicability, predominantly regarding study population, pretests and index test. The current evidence supporting the sensitivity of CT for predicting malignancy in unilateral pleural effusions (both non-transudative and all types of effusion) is very low and did not allow meta-analysis. Standardization of patient population and CT protocol may facilitate conclusions of futures studies.

Abstract
Background The long-term outcome after non-diagnostic thoracoscopy (idiopathic pleuritis) has not been investigated in nationwide studies, and the survival has never been estimated. Therefore, we decided to investigate the three-year incidence of malignancy and survival of patients with idiopathic pleuritis. Methods Retrospective, register-based, nationwide study of patients undergoing diagnostic video-assisted thoracoscopic surgery (VATS) thoracoscopy ≤30 days after thoracentesis, using The National Patient Registry and The Danish Cancer Registry. Idiopathic pleuritis was defined as; no diagnosis of malignancy within 31 days after VATS. Patients were followed for 36 months after VATS. Results In total, idiopathic pleuritis were identified in 547 out of 658 patients undergoing VATS (83%), and 29 (5%) were diagnosed with malignancy during the 3 years follow-up period after VATS. Of these, 93% were diagnosed with malignancy within the first year. Numbers-needed-to-follow-up for detecting one case of malignancy was 18 during the first year after VATS and 250 in the two subsequent years. Survival was independent on type of malignancy (MPM vs. other malignancies; P=0.13) and of time from VATS to diagnosis (≤31 days vs. 1-36 months; P=0.15). Median survival in the non-malignant group was 1,095 days. Conclusions Our study confirms a low incidence of malignancy in idiopathic pleuritis after VATS. Nearly all incident cases of malignancy were diagnosed within 12 months from VATS. No survival disadvantage was observed in patients with incident malignancy. Our data suggest that follow-up of idiopathic pleuritis could safely be limited to 1 year. The optimal follow-up strategy remains to be investigated.

Abstract
BACKGROUND Trocar pigtail catheter thoracentesis (TPCT) is a common procedure often performed by junior physicians. Simulation-based training may effectively train physicians in the procedure prior to performing it on patients. An assessment tool with solid validity evidence is necessary to ensure sufficient procedural competence. OBJECTIVES Our study objectives were (1) to collect evidence of validity for a newly developed pigtail catheter assessment tool (Thoracentesis Assessment Tool [ThorAT]) developed for the evaluation of TPCT performance and (2) to establish a pass/fail score for summative assessment. METHODS We assessed the validity evidence for the ThorAT using the recommended framework for validity by Messick. Thirty-four participants completed two consecutive procedures and their performance was assessed by two blinded, independent raters using the ThorAT. We compared performance scores to test whether the assessment tool was able to discern between the two groups, and a pass/fail score was established. RESULTS The assessment tool was able to discriminate between the two groups in terms of competence level. Experienced physicians received significantly higher test scores than novices in both the first and second procedure. A pass/fail score of 25.2 points was established, resulting in 4 (17%) passing novices and 1 (9%) failing experienced participant in the first procedure. In the second procedure 9 (39%) novices passed and 2 (18%) experienced participants failed. CONCLUSIONS This study provides a tool for summative assessment of competence in TPCT. Strong validity evidence was gathered from five sources of evidence. A simulation-based training program using the ThorAT could ensure competence before performing thoracentesis on patients.

Abstract
Due to the increasing role of endosonography [endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and esophageal ultrasound-guided fine needle aspiration (EUS-FNA)] in the diagnosis of several lung diseases, the knowledge of technical aspects is mandatory to optimize the success of the procedure. Among those technicalities related to the procedure, the choice of a needle over another one-either in terms of dimension and type-may have a role in the diagnostic process, especially in some diseases such as lymphoproliferative disorders. In this review, we analyze the current knowledge about the biopsy needle for endosonography, providing also some hints for the future.

Abstract
BACKGROUND Several studies have shown the beneficial effects of mastery learning of a simulation-based course, but not all trainees complete it. OBJECTIVES The purpose of this study was to find deciding factors for the completion of a simulation-based mastery learning course with distributive practice in flexible bronchoscopy. METHODS Seventy-seven trainees who signed up for the course were invited to a survey for deciding factors of completing the course. Sixty-two (81%) trainees answered the survey. RESULTS Male trainees were more likely to complete the course. The most important factor for completion was clinical relevance, and the most important factor for not completing the course was being "too busy." CONCLUSION Several deciding factors for completing the course were identified. Successful simulation-based mastery learning courses should be clinically relevant, and the trainees should be provided protected time to complete the training. The instructional design should also be adapted systematically for male and female trainees to achieve the necessary competencies.

Abstract
BACKGROUND Diagnosing centrally located lung tumors without endobronchial abnormalities and not located near the major airways is a diagnostic challenge. Tumors near or adjacent to the esophagus can be aspirated and detected with esophageal ultrasound (EUS) using gastrointestinal endoscopes. OBJECTIVE To assess the feasibility and diagnostic yield of endoscopic ultrasound with bronchoscope-guided fine needle aspiration (EUS-B-FNA) in paraesophageally located lung tumors and its added value to bronchoscopy and endobronchial ultrasound (EBUS). METHODS Retrospective, multicenter international study (from January 1, 2015 until January 1, 2018) of patients with suspected lung cancer, undergoing bronchoscopy, EBUS, and endoscopic ultrasound bronchoscopy (EUS-B) in one session by a single operator (pulmonologist), in whom the primary lung tumor was detected and aspirated by EUS-B. In the absence of malignancy following endoscopy, transthoracic ultrasound needle aspiration, clinical and radiological follow-up of at least 6 months was performed. The yield and sensitivity of EUS-B-FNA and its added value to bronchoscopy and EBUS was assessed. RESULTS 58 patients were identified with the following diagnosis: non-small-cell lung cancer (n = 43), small-cell lung cancer (n = 6), mesothelioma (n = 2), metastasis (n = 1), nonmalignant (n = 6). The yield and sensitivity of EUS-B-FNA for detecting lung cancer was 90%. In 26 patients (45%), the intrapulmonary tumor was exclusively detected by EUS-B. Adding EUS-B to conventional bronchoscopy and EBUS increased the diagnostic yield for diagnosing lung cancer in para-esophageally located lung tumors from 51 to 91%. No EUS-B-related complications were observed. CONCLUSION EUS-B-FNA is a feasible and safe technique for diagnosing centrally located intrapulmonary tumors that are located near or adjacent to the esophagus. EUS-B should be considered in the same endoscopy session following nondiagnostic bronchoscopy and EBUS.

Safety and clinical feasibility of injecting a novel liquid fiducial marker for use in image guided radiotherapy in 15 patients with non-small cell lung cancer are reported. No major safety or toxicity issues were encountered. Markers present at start of radiotherapy remained visible in cone beam computed tomography and fluoroscopy images throughout the treatment course and on computed tomography images during follow-up (0-38 months). Marker volume reduction was seen until 9 months after treatment, after which no further marker breakdown was found. No post-treatment migration or marker related complications were found.

Abstract
OBJECTIVE To provide an overview of current literature that informs how to approach simulation practice of bronchoscopy and discuss how findings from other simulation research can help inform the use of simulation in bronchoscopy training. SUMMARY We conducted a literature search on simulation training of bronchoscopy and divided relevant studies in three categories: 1) structuring simulation training in bronchoscopy, 2) assessment of competence in bronchoscopy training, and 3) development of cheap alternatives for bronchoscopy simulation. CONCLUSION Bronchoscopy simulation is effective, and the training should be structured as distributed practice with mastery learning criteria (ie, training until a certain level of competence is achieved). Dyad practice (training in pairs) is possible and may increase utility of available simulators. Trainee performance should be assessed with assessment tools with established validity. Three-dimensional printing is a promising new technology opening possibilities for developing cheap simulators with innovative features.

Abstract
BACKGROUND Interactive breath-hold control (IBC) may improve the accuracy and decrease the complication rate of computed tomography (CT)-guided lung biopsy, but this presumption has not been proven in a randomized study. METHODS Patients admitted for CT-guided lung biopsy were randomized to biopsy either with (N=201) or without (N=206) IBC. Biopsy accuracy, procedure time, radiation, and complications were compared in the two groups. Predictors for pneumothorax were analyzed. RESULTS Procedures performed with the use of IBC (N=130) did not show higher biopsy accuracy (P=0.979) but were associated with a higher risk of pneumothorax (P=0.022) compared to procedures without the use of IBC (N=171). Overall, 50% of the biopsies were malignant, 13% were benign, and 33% were inconclusive (4% missing). Long needle time (P=0.037) and small nodule size (P=0.001) were predictors of pneumothorax. CONCLUSIONS The use of IBC for CT-guided lung biopsy was not an advantage for unselected patients in our care, since it did not improve the biopsy accuracy and the risk of pneumothorax was increased.

Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) plays a key role in the staging of lung cancer, which is crucial for allocation to surgical treatment. EBUS-TBNA is a complicated procedure and simulation-based training is helpful in the first part of the long learning curve prior to performing the procedure on actual patients. New trainees should follow a structured training programme consisting of training on simulators to proficiency as assessed with a validated test followed by supervised practice on patients. The simulation-based training is superior to the traditional apprenticeship model and is recommended in the newest guidelines. EBUS-TBNA and oesophageal ultrasound-guided fine needle aspiration (EUS-FNA or EUS-B-FNA) are complementary to each other and the combined techniques are superior to either technique alone. It is logical to learn and to perform the two techniques in combination, however, for lung cancer staging solely EBUS-TBNA simulators exist, but hopefully in the future simulation-based training in EUS will be possible.

Abstract
BACKGROUND The use of simulators in a training programme for technically challenging procedures has the advantages of lowering the risk of patient complications while helping the trainees with the initial part of their learning curve. OBJECTIVES The aim of this study was to perform a systematic review of simulation-based training in flexible bronchoscopy and endobronchial ultrasound (EBUS). METHODS We identified 1,006 publications in the PubMed database and included publications on flexible bronchoscopy below the carina and EBUS involving hands-on simulation-based training. Publications were excluded if they were written in languages other than English, if paediatric airways were involved or if they were not journal articles. The screening process was performed by 2 individuals, and a third reviewer made the final decision in case of disagreement. RESULTS We included 30 publications. The studies included participants of varying experience and most commonly used a virtual reality simulator as a training modality. Assessment of the participants' skills was based on simulator metrics or on an assessment tool. Some studies included performance on patients for assessment of the operator after training on a simulator. CONCLUSIONS Simulation-based training was demonstrated to be more efficient than the traditional apprenticeship model. Physical models and virtual reality simulators complement each other. Simulation-based education should be based on a mastery learning approach and structured as directed self-regulated learning in a distributed training programme.

Abstract
BACKGROUND Biopsy-based diagnosis in patients with paraesophageal intrapulmonary tumors suspected of lung cancer is crucial for adequate treatment planning. OBJECTIVE To evaluate the performance of transesophageal endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in the diagnosis of intrapulmonary tumors located near or adjacent to the esophagus. METHODS We performed a systematic review (PROSPERO, CRD42016033737) and searched MEDLINE, Embase, BIOSIS Previews, and Web of Science on September 22, 2016, without date or language restrictions. We included studies that evaluated the yield and/or sensitivity of EUS-FNA for diagnosing intrapulmonary tumors. Yield was defined as the number of patients in whom EUS-FNA made a biopsy-proven diagnosis (malignant or nonmalignant) relative to the total number of patients on whom EUS-FNA was performed. Sensitivity was defined as the number of patients in whom EUS-FNA made a biopsy-proven diagnosis of malignancy relative to the total number of patients in whom the tumor was found to be malignant. We performed a random-effects meta-analysis. RESULTS Of 3,320 search results, 11 studies were included. Ten had a high risk of bias. The total number of patients was 313; the proportion of patients with malignancy ranged from 87 to 100% across these studies. The average yield was 0.90 (95% CI 0.82-0.95) and the average sensitivity was 0.92 (0.83-0.96). In the subgroup of prospective studies (n = 3), the average yield was 0.80 (0.56-0.93) and the average sensitivity was 0.83 (0.58-0.95). EUS-FNA-induced complications were reported for 5/256 patients (2.0%) for whom this information was available. CONCLUSIONS Although the number of high-quality studies is limited, these findings suggest that EUS-FNA is safe and has a high yield for diagnosing intrapulmonary tumors.

Abstract
BACKGROUND Simulation training is a revolutionary addition to health care education. However, developing simulation-based training programs is often dictated by those simulators that are commercially available. Curriculum development requires deliberate planning and a standardized approach, including a 'general needs assessment'. OBJECTIVES The aim of this study was to perform a national general needs assessment to identify technical procedures in pulmonary medicine that should be integrated in a simulation-based curriculum. METHODS A three-round Delphi process was initiated among 62 key opinion leaders. Round 1 was an open-ended question to identify technical procedures pulmonologists should learn. Round 2 was a survey using a newly developed needs assessment formula to explore the frequency of procedures, number of operators, risk or discomfort when performed by an inexperienced doctor, and feasibility of simulation-based training. In round 3, results were reviewed and ranked according to priority. RESULTS The response rates for the three rounds were 74, 63, and 60%, respectively. The Delphi process reduced the 30 procedures identified in round 1 to 11 prioritized technical procedures in round 3. These were: flexible bronchoscopy, pleurocentesis, endobronchial ultrasound, endoscopic ultrasound-guided fine-needle aspiration, noninvasive ventilation treatment, transthoracic biopsy of pleural or lung tumor, focused ultrasound scanning of the lungs, chest tube insertion, needle biopsy of visible lymph node/tumor of the skin, focused ultrasound scanning of the heart, and thoracoscopy. CONCLUSION We performed a Delphi study using a needs assessment formula, which identified 11 technical procedures that are highly suitable for simulation-based training. Medical educators can use this list as a resource in planning simulation-based training programs for trainees in pulmonary medicine.

Abstract
Liver biopsy using transesophageal bronchoscopic ultrasound-guided fine needle aspiration (EUS-B-FNA) has never been described before and biopsies of infradiaphragmatic lesions using this technique are not considered to be standard. A patient suspected for primary lung cancer with multiple lesions in the liver was referred to our department. We conducted bronchoscopy and endobronchial ultrasound-guided (EBUS) biopsy from several enlarged mediastinal lymph nodes. Thereafter, we conducted EUS-B-FNA from a lesion in the left liver lobe. Pathology showed that the liver lesion represented a metastasis from a pulmonary adenocarcinoma. Bronchoscopy and EBUS samples were not able to establish diagnosis. We hereby demonstrated that a diagnostic EUS-B-FNA from a liver metastasis in a patient with lung cancer is possible. This underlines that chest physicians should not forget the esophagus when staging lung cancer.
