Stenting at the flow-limiting segment can improve the ventilation-perfusion ratio in patients with central airway stenosis. However, there is no quantitative examination for assessing the perfusion status during interventional bronchoscopy. Intrabronchial capnography can estimate regional gas exchange by measuring carbon dioxide concentration. We herein report a case of bilateral bronchial stenosis where stenting was able to improve ventilation-perfusion ratio using intrabronchial capnography. A 44-year-old man was admitted to our institution with orthopnea...

Bronchial thermoplasty (BT) is a bronchoscopic treatment for patients with severe asthma who remain symptomatic despite optimal medical therapy. In this "expert best practice" paper, the background and practical aspects of BT are highlighted. Randomized, controlled clinical trials have shown BT to be safe and effective in reducing severe exacerbations, improving quality of life, and decreasing emergency department visits. Five-year follow-up studies have provided evidence of the functional stability of BT-treated patients with persistence of a clinical benefit...

INTRODUCTION AND OBJECTIVES: Tracheal stenosis is a rare and challenging disease. Bronchoscopy is the gold standard for diagnosis and assessment but brings inherent risks. Spirometry is commonly used to access obstructions but is not always feasible due to patient related factors. We therefore considered impulse oscillometry (IOS) as a non-invasive method to quantify airway obstruction and its potential use for diagnosis and follow-up of tracheal stenosis. MATERIALS AND METHODS: Patients with confirmed tracheal stenosis were recruited between January 1st, 2015 and December 31st, 2016...

INTRODUCTION: Endobronchial one-way valves have been proposed as treatment for persistent air leak complicating spontaneous pneumothorax in which surgical intervention is not feasible. However, published data on efficacy, safety, and factors associated with success are scanty. METHODS: This is a retrospective study of 37 patients at a general hospital from 2008 to 2016. The impact of endobronchial valve implantation on the time to air-leak cessation after bronchoscopy was evaluated...

Airway malacia can occur in the larynx (larygomalacia), trachea (tracheomalacia), or bronchi (bronchomalacia). As a group these are the most common congenital abnormalities of the pediatric airway and are characterized by increased airway compliance, resulting in excessive dynamic collapse during the respiratory cycle. While a diagnosis can be suspected based on clinical history and physical examination, definitive evaluation is based of nasopharyngolaryngoscopy and/or bronchoscopy. Observation and conservative management are typically all that are required...

We use pulmonary interventional procedures for the diagnosis of pulmonary diseases either for benign or malignant lesions. Flexible bronchoscopy with or without radial endobronchial ultrasound, convex-probe endobronchial ultrasound and electromagnetic navigation are procedures performed in centers with experience in diagnostic pulmonary medicine. The method of sedation and ventilation is very important in order to avoid or handle with success complications. Proper respiration during pulmonary (or other interventional) procedures is a key factor...

Idiopathic pulmonary haemosiderosis (IPH) is a diagnosis of exclusion, which is characterized by persistent or recurrent episodes of alveolar haemorrhage. Early diagnosis of IPH, especially in the case of first-time manifestation, is challenging because previous episodes of alveolar haemorrhage are often difficult to prove. Repeated episodes of alveolar haemorrhage can result in chronic iron-deficient anaemia and irreversible interstitial fibrosis; thus, early recognition and intervention are desirable in terms of clinical outcome...

BACKGROUND: Interventional bronchoscopy is considered an effective treatment option for malignant central airway obstruction (MCAO). However, there are few reports of interventional bronchoscopy in patients with MCAOs due to extra-pulmonary malignancy. Therefore, the objective of this study was to investigate treatment outcomes and prognostic factors for bronchoscopic intervention in patients with MCAO due to extra-pulmonary malignancy. METHODS: We retrospectively analyzed consecutive 98 patients with MCAO due to extra-pulmonary malignancy who underwent interventional bronchoscopy between 2004 and 2014 at Samsung Medical Center (Seoul, Korea)...

BACKGROUND AND OBJECTIVE: Malignant airway obstruction (MAO), a common complication of patients with advanced lung cancer, causes debilitating dyspnoea and poor quality of life. Two common interventions used in the treatment of MAO include bronchoscopy with airway stenting and external beam radiotherapy (EBRT). Data are limited regarding their clinical effectiveness and overall effect on survival. METHODS: A retrospective chart review of patients treated with airway stenting and/or EBRT at the Johns Hopkins Hospital for MAO between July 2010 and January 2017 was reviewed...

Interventional endoscopy (e.g., bronchoscopy, colonoscopy, laparoscopy, cystoscopy) is a widely performed procedure that involves either diagnosis of suspicious lesions or guidance for minimally invasive surgery in a variety of organs within the body cavity. Endoscopy may also be used to guide the introduction of certain items (e.g., stents) into the body. Endoscopic navigation systems seek to integrate big data with multimodal information (e.g., computed tomography, magnetic resonance images, endoscopic video sequences, ultrasound images, external trackers) relative to the patient's anatomy, control the movement of medical endoscopes and surgical tools, and guide the surgeon's actions during endoscopic interventions...

BACKGROUND: Critical central airway obstruction (CAO) requires emergent airway intervention, but current guidelines lack specific recommendations for airway management in the emergency department (ED) while awaiting rigid bronchoscopy. There are few reports of the use of noninvasive ventilation (NIV) in tracheomalacia, but its use as a temporizing treatment option in fixed, malignant CAO has not, to the best of our knowledge, been reported. CASE REPORT: An 84-year-old woman presented to the ED in respiratory distress, too breathless to speak and using her accessory muscles of respiration, with bilateral rhonchi throughout the lung fields...

BACKGROUND: Nontypeable Haemophilus influenzae (NTHi), the most common bacterial lower airway infection in children with protracted bacterial bronchitis, is associated with progression to bronchiectasis. We determined whether vaccination with 10-valent pneumococcal NTHi protein-D conjugate vaccine (PHiD-CV) reduced NTHi lower airway infection compared to children not PHiD-CV-vaccinated. Our unique childhood vaccination schedule and prospective 9-year bronchoalveolar lavage (BAL) collection provided an exclusive opportunity to examine this hypothesis...
