Human airway is generally destructed by inhaled factors and is the barrier to the external environment and has a crucial role in protection of the internal homeostasis of the lung. Sulfur mustard (SM) is a chemical warfare that capable of producing severe chemical injuries primarily in the lungs. Trefoil factor family (TFFs) plays major roles in epithelial repair and homeostasis, particularly in the lung. This study attempted to verify the role of TFFs in airway that induced by sulfur mustard. Fifteen patients exposed to SM and 10 non-exposed subjects were enrolled in this study...

Satisfactory functional outcomes following bronchoscopic lung volume reduction (BLVR) using endobronchial valves (EBVs) depend on the absence of collateral ventilation (CV) between the target and adjunct lobes. The Chartis system has proven to be useful for determining whether CV is present or absent, but this system can also erroneously indicate the absence of CV, which can lead to BLVR failure. Here, we describe low-flow Chartis phenotype in the target lobe resulted in difficult judgment of existence of CV...

Aim Carcinoid tumors of the lung are the tumors originating from the neuroendocrine cells. Surgical excision remains the gold standard for the treatment. Treatment with interventional bronchoscopic excision has also been reported as an alternative option in typical carcinoid tumors of the lung. The aim of this study was to present results and outcomes in patients who were bronchoscopically treated and followed-up. Methods Data of 14 patients, who had undergone bronchoscopic excision due to typical carcinoid tumor of the lung between April 2008 and July 2015 were retrospectively evaluated...

BACKGROUND: Endobronchial ultrasonography (EBUS)-guided transbronchial needle aspiration allows for sampling of mediastinal lymph nodes. The external diameter, rigidity, and angulation of the convex probe EBUS renders limited accessibility. This study compares the accessibility and transbronchial needle aspiration capability of the prototype thin convex probe EBUS against the convex probe EBUS in human ex vivo lungs rejected for transplant. METHODS: The prototype thin convex probe EBUS (BF-Y0055; Olympus, Tokyo, Japan) with a thinner tip (5...

We present a rare case of endobronchial hamartoma that required right middle and lower lobectomy. A 59-year-old man presented with cough and sputum lasting for 9 months. Chest X-ray revealed obstructive pneumonia of the right inferior lobe. Chest computed tomography demonstrated an intrabronchial mass lesion, size 12×12 mm, occluding the entrance of the right lower lobe bronchus associated with obstructive pneumonia of the right inferior lobe. Because transbronchial biopsy could not confirm the diagnosis, we performed a right middle and lower lobectomy to diagnose and treat obstructive pneumonia...

Sarcoidosis is an idiopathic disease that most commonly involves the lungs and is characterized by granulomatous inflammation. Bronchiectasis is one pulmonary manifestation of sarcoidosis, although it is almost always observed as traction bronchiectasis in the setting of fibrotic lung disease. A 50-year-old woman was evaluated for chronic cough and bronchiectasis with a small amount of peripheral upper lobe honeycombing and no significant pulmonary fibrosis or lymphadenopathy. After an extensive laboratory and imaging evaluation did not identify a cause of her bronchiectasis, bronchoscopy was performed to assess for primary ciliary dyskinesia and revealed a diffuse cobblestone appearance of the airway mucosa...

Endobronchial carcinoid tumors are the most common intrabronchial tumors in children and adolescents. Common signs and symptoms include persistent cough and wheezing not responsive to bronchodilators, hemoptysis, and recurrent fever. Diagnosis is frequently made by imaging and direct visualization with flexible bronchoscopy; surgery remains the gold standard treatment, and lung-sparing resections should be performed whenever possible. Though carcinoid syndrome-characterized by flushing, palpitations, wheezing, shortness of breath, and diarrhea-has been found in association with adult bronchial carcinoid tumors, to our knowledge only one previous study has reported the presence of carcinoid syndrome in a pediatric patient with an endobronchial carcinoid...

BACKGROUND: Nowadays, small peripheral pulmonary lesions (PPLs) are frequently detected and the prognosis of lung cancer depends on the early diagnosis. Because of the high fee and requiring specialized training, many advanced techniques are not available in many developing countries and rural districts. METHODS: Three sets of opaque soft copper wires visible under the fluoroscopy (Flu) in the Flu-flexible bronchoscopy (FB) group (n = 24), which determined the three planes of the lesion, were respectively placed firmly on the surface of the chest wall with adhesive tape on the chest wall...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive and safe technique for a sampling of mediastinal lesions. Indications for EBUS-TBNA have gradually expanded since its introduction. The usual approach to cytological sampling of the thyroid gland is percutaneous ultrasound-guided fine needle aspiration (US-FNA) performed under local anesthesia. US-FNA may be risky or not feasible in intrathoracic/substernal thyroid location. Feasibility of aspirating thyroid lesions with EBUS-TBNA has been occasionally reported...

Cough is often a distressing feature and may be caused due to varied reasons. A 39-year-old man presented with complaints of cough and had significant pigeon exposure. His chest X-ray revealed mediastinal enlargement and computed tomography chest revealed air trapping and mediastinal lymphadenopathy. Both endobronchial and transbronchial biopsies revealed granulomas. Thus, the patient was diagnosed as a case of sarcoidosis and started on steroids. Hypersensitivity pneumonitis may often mimic sarcoidosis; however, the presence of endobronchial granulomas will diagnose the latter condition...

The tracheobronchial origin of non-Hodgkin's lymphoma (NHL) is a very rare presentation, and there are only a few case reports of primary tracheal or endobronchial NHL. We have two cases of primary tracheobronchial NHL; one case was incidentally diagnosed as anaplastic large cell lymphoma of endobronchial origin when a comprehensive workup and surgery were carried out for an endobronchial aspergilloma which was actually sitting on top of lymphoma. The second patient was a case of myelodysplastic syndrome who presented with acute respiratory distress; on thorough workup, he was found to have endotracheal B-cell lymphoma...

BACKGROUND: Recent studies have shown differential response to chemotherapy among the subtypes of non-small cell lung carcinoma (NSCLC). Therefore, to accurately differentiate between the types of lung cancer is of paramount importance. Transbronchial biopsy using endobronchial ultrasonography with a guide sheath (EBUS-GS) is a promising method for the diagnosis of NSCLC. The purpose of this study was to evaluate the consistency between the types of lung cancer histologically diagnosed by bronchial biopsy or cytologically by EBUS-GS, and the final diagnosis of the resected specimen...

BACKGROUND AND OBJECTIVE: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a minimally invasive technique for diagnosing intrathoracic malignancies and some benignancies; however, there are no data available on the utility of EBUS-TBNA for the diagnosis of non-specific inflammatory intrathoracic lymphadenitis. METHODS: A prospective analysis was performed from 104 patients with enlarged lymphadenopathy suspected of non-specific lymphadenitis referred for EBUS-TBNA between October 2009 and March 2012...

Mendelian susceptibility to mycobacterial diseases (MSMD) are a spectrum of inherited disorders characterized by localized or disseminated infections caused by atypical mycobacteria. Interferon-γ receptor 1 (IFNGR1) deficiency was the first identified genetic disorder recognized as MSMD. Mutations in the genes encoding IFNGR1 can be recessive or dominant and cause complete or partial receptor deficiency. We present the case of a 2½-year-old boy with a history of recurrent wheezing, diagnosed with endobronchial mycobacterial infection...

Chun-Yu Lin, Fu-Tsai Chung
The diagnosis of central airway tumors is usually challenging because of the vague presentations. Advances in visualization technology in bronchoscopy aid early detection of bronchial lesion. Cryotechnology has great impact on endobronchial lesion sampling and provides better diagnostic yield. Airway tumor involvements result in significant alteration in life quality and lead to poor life expectancy. Timely and efficiently use ablation techniques by heat or cold energy provide symptoms relief for central airway obstruction...

BACKGROUND: Computed tomography guided transthoracic needle aspiration (CT-TTNA) and endobronchial ultrasonography with guide sheath (EBUS-GS) transbronchial lung biopsy are important methods for the diagnosis of peripheral pulmonary lesions (PPLs). Without enough evidence, it is controversial which is a better choice for diagnosing PPLs. In this study, we hypothesized that the complication rate of EBUS-GS would be lower than CT-TTNA and the diagnostic accuracy of EBUS-GS were not inferior to CT-TTNA...

BACKGROUND: Endoscopic techniques, including endobronchial ultrasound (EBUS) and endoscopic ultrasound (EUS), are the initial approach for the diagnosis and staging of lung cancer and the diagnosis of mediastinal and hilar lesions. Historically, the transvascular approach has been avoided because of concerns of bleeding. Here we review our experience with EBUS and EUS transvascular biopsy of mediastinal, hilar, and lung lesions. METHODS: A prospective research database was used to retrospectively identify and review the records 33 consecutive patients who underwent EBUS and EUS transvascular biopsy in an outpatient setting over 4 years...

BACKGROUND: Transoesophageal endobronchial ultrasound (EBUS) video-bronchoscope insertion provides pulmonologists access to conduct endoscopic fine-needle aspiration (EUS-B-FNA) of mediastinal lymph node (LN) lesions and also assist in lung cancer staging by sampling left adrenal gland (LAG) lesions. Limited literature have described additional diagnostic value, whilst maintaining patient safety. METHODS: All eligible patients with paraoesophageal lesions on thoracic computed tomography (CT) underwent pulmonologist-performed EUS-B-FNA at two tertiary centres and were included in this prospective observational cohort study...
