Female, 85 y.o., weighting 60kg, multiple trauma patient. After an initial laparotomy, an emergent thoracotomy was performed using a bronchial blocker for lung isolation (initial active suction was applied). During surgery, bronchial cuff was deflated, causing a self-limited tracheal blood flooding. A second lung isolation was attempted but it was not as effective as initially. Probably, a lung collapse with the same bronchial blocker was impaired in the second attempt because of the obstruction of bronchial blocker lumen by intraoperative endobronchial hemorrhage...

Endobronchial obstruction is a known cause of an unexpandable lung. Endobronchial lesions are usually malignant, however benign cause like hemartoma, lipoma, amyloidosis and neuroendocrine tumors are known. We, hereby present the rare cause of bronchial elastosis presenting as right lower lobe lung collapse.

An 11-month-old healthy infant girl was noted to have left lower lobe (LLL) opacities on chest X-ray (CXR) after developing desaturations during an elective cochlear implant surgery. Repeat CXR 10 days later revealed hyperexpansion of the left lung and persistent LLL opacity. Chest computerized tomography revealed enlarged mediastinal lymph nodes, left mainstem bronchial obstruction, and nodular opacities. Bronchoscopic biopsy of the endobronchial tissue revealed multiple necrotizing granulomas and grew Mycobacterium avium-intracellulare, Streptococcus viridans, and Actinomyces odontolyticus...

Retained foreign bodies within the stomach and proximal small bowel may be problematic in patients with prior cerebrovascular injury or head, neck and esophageal malignancy, given the increased vulnerability of this patient population to complications from aspiration and increased difficulty of esophagogastroduodenoscopy in cases of tumoral obstruction. This article presents an alternative method for foreign body retrieval through an existing gastrostomy tract, which offers the benefits of fast procedure times, reduction in radiation dose and fluoroscopy time, and allows for safer retrieval of foreign bodies by using direct visualization...

A case of tracheobronchial stenosis due to tuberculosis in a young woman is presented. Compromised pulmonary function due to near-total obstruction of the proximal left main bronchus was diagnosed. Treatment options included surgical resection, endobronchial dilation or stenting, and argon photocoagulation. An approach was chosen to address symptoms without aggressive resection or commitment to stenting. She remains monitored and, while possibly committed to future intervention, no bridges have been burned with respect to more definitive and invasive therapies...

We present here a 47-year old male patient who had a typical carcinoid tumor located at the orifice of right lower lobe bronchus underwent uniportal thoracoscopic lower lobectomy following bronchoscopic removal of the endobronchial tumor. Tumor was seen by bronchoscopy to protrude out from the lower lobe into the intermediary bronchus obstructing the lower lobe completely and the middle lob partially. However, the origin of the endobronchial tumor was in the distal part of the lower lobe bronchus. In this case, open surgery could be an alternative to save the middle lobe by incising the lower lobe bronchus to pull out the endobronchial tumor first during thoracotomy...

Primary pulmonary tuberculosis can involve regional lymph nodes which may resolve spontaneously or on treatment; or they may enlarge causing extrinsic bronchial compression; or cause endobronchial inflammation and ulceration; or a node may erode through the bronchial wall with extrusion of caseous materials into the bronchial tree, causing focal or lobar pneumonia. This erosion is seen radiologically as hilar lymphadenopathy, with atelectasis and consolidation and described as "epituberculosis". It is more common in infants than older children...

BACKGROUND AND OBJECTIVE: Intratumoral administration of chemotherapeutic agents is a treatment modality that has proven efficacious in reducing the recurrence of tumours and increases specificity of treatment while minimizing systemic side effects. Direct intratumoral injection of malignant airway obstruction has potential therapeutic benefits but tissue drug concentrations and side-effect profiles are poorly understood. METHODS: Bronchial wall injection of generic paclitaxel (PTX) (102 injections of 0...

COPD is the most frequent chronic respiratory disease and a leading cause of morbidity and mortality. The major risk factor for COPD development is cigarette smoke, and the most efficient treatment for COPD is smoking cessation. However, even after smoking cessation, inflammation, apoptosis, and oxidative stress may persist and continue contributing to disease progression. Although current therapies for COPD (primarily based on anti-inflammatory agents) contribute to the reduction of airway obstruction and minimize COPD exacerbations, none can avoid disease progression or reduce mortality...

Asthma is an incurable chronic disease affecting approximately 24 million people in the United States. The hallmark features of asthma are reversible airflow obstruction, airway hyperresponsiveness, airway inflammation, bronchoconstriction, and excessive mucus secretion. Clinical symptoms include episodic or persistent breathlessness, wheezing, cough, or chest tightness/pressure. Forty-five percent of asthmatics continue to have yearly exacerbations and the disease is responsible for approximately 3,600 annual deaths...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is considered useful for the staging and diagnosis of lung cancer or thoracic lymph node enlargement; however, little is known about its complications. Between July 2009 and November 2016, 413 patients underwent EBUS-TBNA, and four complications (0.97%) occurred. Here we report four cases involving complications of EBUS-TBNA, including mediastinitis (n = 2), obstructive pneumonia (n = 1), and airway obstruction requiring admission to the intensive care unit (n = 1)...

BACKGROUND: The development of central airway obstruction during malignant diseases is an important cause of morbidity and mortality. Endobronchial therapies can decrease the patient's symptoms and improve quality of life. Here, we compare airway recanalization methods: argon plasma coagulation with mechanical tumor resection (APC + MTR) and cryorecanalization (CR efficiency, complications, restenosis rate, and time to restenosis) in patients with malignant exophytic endobronchial airway obstruction...

BACKGROUND: Patients with asthma present structural and inflammatory alterations that are believed to play a role in disease severity. However, airway remodeling and inflammation have not been extensively investigated in relation to both symptom control and airflow obstruction in severe asthmatics. We aimed to investigate several inflammatory and structural pathological features in bronchial biopsies of severe asthmatics that could be related to symptom control and airflow obstruction after standardized treatment...

More than half of primary lung cancers are not resectable at diagnosis and 40% of deaths may be secondary to loco-regional disease. Many of these patients suffer from symptoms related to airways obstruction. Indications for therapeutic endoscopic treatment are palliation of dyspnea and other obstructive symptoms in advanced cancerous lesions and cure of early lung cancer. Bronchoscopic management is also indicated for all those patients suffering from benign or minimally invasive neoplasm who are not suitable for surgery due to their clinical conditions...

BACKGROUND AND OBJECTIVE: Chronic exposure to biomass smoke (BS) can significantly compromise pulmonary function and lead to chronic obstructive pulmonary disease (COPD). To determine whether BS exposure induces a unique phenotype of COPD from an early stage, with different physiopathological features compared with COPD associated with smoking (cigarette-smoke (CS) COPD), we assessed the physiopathology of early COPD associated with BS exposure (BS COPD) by incorporating spirometry, high-resolution computed tomography (HRCT) imaging, bronchoscopy and pathological examinations...

Chronic obstructive pulmonary disease (COPD) has no curative treatment, and in moderate to advanced stages, functional parameters and quality of life are affected. Lung volume reduction improves respiratory parameters and quality of life of these patients. Endoscopic lung volume reduction is a minimally invasive procedure that uses endobronchial valves or coils. Valves are unidirectional, blocking the air from entering the target lobe during inspiration, allowing the exit of air and secretions during expiration...

BACKGROUND: Bronchial carcinoid tumors (BCTs) are rare neuroendocrine neoplasms of the lung that mainly have a central distribution. They are classified as typical and atypical, with the former variant generally conferring a more favorable survival. Central tumors are usually symptomatic with features of bronchial obstruction, whereas peripheral tumors may remain silent. CASE REPORT: A 36-year-old woman presented to our hospital due to an episode of massive hemoptysis 5 days prior to admission...
