Interventional bronchoscopy

Most of the small-cell lung cancer patients are of the central type of lung cancer. Small-cell lung cancer often intrudes into the atmospheric tract and large blood vessels, thus causing severe tracheobronchial stenosis and superior vena cava syndrome. In addition, patients with malignant tumors, especially those with respiratory failure and severe hypoxia, can be complicated with thromboembolic diseases. We reported a 65-year-old woman with severe stenosis of the trachea, and right main bronchus complicated with acute respiratory failure was treated with bronchoscopy and stent implantation to improve the patient's dyspnea, thus successfully receiving chemotherapy and timely treatment...

BACKGROUND: Central airway obstruction (CAO) can lead to acute respiratory failure (RF) necessitating positive pressure ventilation (PPV). The efficacy of airway stenting to aid liberation from PPV in patients with severe acute RF has been scarcely published. We present a systematic review and our recent experience. METHODS: A systematic review of PubMed was performed, and a retrospective review of cases performed at our two institutions from 2018 to 2022 in adult patients who needed stent insertion for extrinsic or mixed CAO complicated by RF necessitating PPV...

Obstructive fibrinous tracheal pseudomembrane (OFTP) is a relatively rare complication of endotracheal intubation. Despite being well documented, the exact pathogenesis of OFTP remains unclear. Some studies suggest that it may arise from the early stage of ischemic tracheal wall injury caused by the cuff pressure during intubation. Diagnosis and treatment of OFTP can be facilitated through therapeutic bronchoscopy. In this case report, we describe a patient who presented with dyspnea following repeated intratracheal interventions and was diagnosed with OFTP...

INTRODUCTION: Lung cancer remains the leading cause of cancer death worldwide. Subsolid nodules (SSN), including ground glass nodules (GGN) and part solid nodules (PSN), are slow growing but have a higher risk for malignancy. Therefore, timely diagnosis is imperative. Shape-sensing robotic-assisted bronchoscopy (ssRAB) has emerged as reliable diagnostic procedure, but data on SSN and how ssRAB compares to other diagnostic interventions such as CT-guided transthoracic biopsy (CTTB) is scarce...

INTRODUCTION: The use of cryobiopsy in conjunction with robotic assisted bronchoscopy is on the rise due to the safety and increased diagnostic yield of cryobiopsy. The incorporation of 3D fluoroscopy in the procedure improves the workflow and helps confirm the accuracy of sampling of peripheral pulmonary nodules. METHODS: We describe an observational series of 12 patients comprising of 15 nodules where cryobiopsy was performed during Shaped sensing robot assisted bronchoscopy cryobiopsy (ssRABcb) under general anesthesia...

BACKGROUND AND OBJECTIVE: Other iatrogenic immunodeficiency-associated lymphoproliferative disorders (OIIA-LPD) are rare but well-known diseases that manifest during or after methotrexate (MTX) administration. Limited information is available on the clinical characteristics of OIIA-LPD of the lung because only a few cases have been reported. Thus, we aimed to assess the incidence and prognosis of patients with OIIA-LPD of the lung. METHODS: Patients with OIIA-LPD of the lung treated at our institution between January 2008 and July 2020 were retrospectively analysed...

This article presents two cases of pulmonary hemorrhage successfully managed using TC-325, a novel hemostatic powder commonly known as Hemospray. Originally approved for endoscopic hemostasis in gastrointestinal bleeding, Hemospray's application in endobronchial bleeding control has not been widely reported. The cases highlight its efficacy in achieving immediate and sustained hemostasis in peripheral pulmonary bleeding, where conventional bronchoscopic therapies may be ineffective. The absence of adverse effects and the rapid cessation of bleeding underscore the potential of Hemospray as a valuable tool in the bronchoscopist's arsenal, especially in life-threatening hemoptysis scenarios...

Limited clinical intervention studies highlight the absence of evidence-based international guidelines for effectively managing post-tuberculosis lung disease, emphasizing bronchiectasis. The aim of this study was to describe a case of left pneumonectomy for severe post-tuberculosis cystic bronchiectasis and to provide a review of the post-surgical mortality rate, complications, survival rate, and the patient's quality of life following the pneumonectomy procedure. A 36-year-old Indonesian male smoker presented with worsening breathing difficulties and fever...

Nocardia is a rarely encountered opportunistic gram-positive bacterium that exhibits marked invasiveness and dissemination. Typically, acquired through trauma or inhalation, this pathogen primarily affects immunocompromised individuals and is a potentially life-threatening risk in severe cases. Nocardia otitidiscaviarum is a particularly rare subtype of Nocardia infection, and the occurrence of concurrent Aspergillus infection is extremely rare. In cases where both infections manifest concomitantly, rapid and accurate diagnosis is essential to facilitate the subsequent selection of appropriate anti-infective interventions...

As computer vision algorithms increase in capability, their applications in clinical systems will become more pervasive. These applications include: diagnostics, such as colonoscopy and bronchoscopy; guiding biopsies, minimally invasive interventions, and surgery; automating instrument motion; and providing image guidance using pre-operative scans. Many of these applications depend on the specific visual nature of medical scenes and require designing algorithms to perform in this environment. In this review, we provide an update to the field of camera-based tracking and scene mapping in surgery and diagnostics in medical computer vision...

BACKGROUND: Foreign Body Aspiration (FBA) is one of the paediatric emergencies which require timely diagnosis and management. The inherent tendency of children to explore small objects with their mouths often prove to be fatal as they are difficult to remove once aspirated. CASE REPORT: We present the case of a 5-year-old boy who presented with dyspnea and vomiting following the aspiration of a pen cap. Chest radiograph and Rigid Bronchoscopy helped to identify the foreign body but it couldn't be removed by Rigid Bronchoscopy alone due it's wedge-shaped nature...

Accidental Foreign body aspiration, especially sharp metallic objects may lead to life threatening complications. A metallic object is identified readily on a Xray chest or CT chest and helps us in ascertaining its location. A straight pin with blunt head in the shape of pearl is used in wearing a head scarf also known as hijab to hold it in place. The head scarf pin (hijab pin) if accidentally aspirated into the airway may lead to grave complications. Hence timely intervention with suitable instrumentation is essential to prevent any lethal complications...

BACKGROUND AND OBJECTIVE: EpiGETIF is a web-based, multicentre clinical database created in 2019 aiming for prospective collection of data regarding therapeutic rigid bronchoscopy (TB) for malignant central airway obstruction (MCAO). METHODS: Patients were enrolled into the registry from January 2019 to November 2022. Data were prospectively entered through a web-interface, using standardized definitions for each item. The objective of this first extraction of data was to describe the population and the techniques used among the included centres to target, facilitate and encourage further studies in TB...

BACKGROUND: Hypoxaemia occurs in approximately 30% of children during anaesthesia for flexible bronchoscopy. High-flow nasal oxygen (HFNO) can prolong safe apnoea time and be used in children with abnormal airways. During flexible bronchoscopy, there is limited evidence if HFNO confers advantages over current standard practice in avoiding hypoxaemia. The aim is to investigate feasibility of HFNO use during anaesthesia for flexible bronchoscopy to reduce frequency of rescue oxygenation and hypoxaemia...

We report the case of a 66-year-old woman who was diagnosed with localized tracheal amyloid light-chain (AL) amyloidosis caused by an underlying B-cell neoplasm. The diagnosis was confirmed through subsequent bronchoscopy and biopsies; however, she experienced a challenging episode of hypoxic respiratory failure that required intervention. Repeat bronchoscopies showed persistent subglottic stenosis and tracheobronchomalacia, which led to tracheal debulking surgery and additional interventions. The patient's treatment began with rituximab, zanubrutinib, and dexamethasone with outpatient follow-up...

INTRODUCTION: Elective flexible bronchoscopy (FB) is now widely available and standard practice for a variety of indications in children with respiratory conditions. However, there are no randomised controlled trials (RCTs) that have examined its benefits (or otherwise).Our primary aim is to determine the impact of FB on the parent-proxy quality-of-life (QoL) scores. Our secondary aims are to determine if undertaking FB leads to (a) change in management and (b) improvement of other relevant patient-reported outcome measures (PROMs)...

INTRODUCTION: Elective flexible bronchoscopy (FB) is now widely available and standard practice for a variety of indications in children with respiratory conditions. However, there is limited evidence regarding the utility of elective FB in children. This systematic review (SRs) aimed to determine the utility of FB on its impact in clinical decision making and quality of life (QoL). METHODS: We searched Pubmed, Cochrane central register of controlled trials, Embase, World Health Organization Clinical Trials Registry Platform and Cochrane database of SRs from inception to April 20, 2023...

The Clinical Techniques, Imaging and Endoscopy Assembly is involved in the diagnosis and treatment of several pulmonary diseases, as demonstrated at the 2023 European Respiratory Society (ERS) International Congress in Milan, Italy. From interventional pulmonology, the congress included several exciting results for the use of bronchoscopy in lung cancer, including augmented fluoroscopy, robotic-assisted bronchoscopy and cryobiopsies. In obstructive lung disease, the latest results on bronchoscopic treatment of emphysema with hyperinflation and chronic bronchitis were presented...

BACKGROUND: Radial probe endobronchial ultrasound (R-EBUS) is often utilized in guided bronchoscopy for the diagnosis of peripheral pulmonary lesions. R-EBUS probe positioning has been shown to correlate with diagnostic yield, but overall diagnostic yield with this technology has been inconsistent across the published literature. Currently there is no standardization for R-EBUS image interpretation, which may result in variability in grading concentricity of lesions and subsequently procedure performance...

INTRODUCTION: The investigation of peripheral pulmonary lesions (PPLs) can be challenging. Several bronchoscopic modalities have been developed to reach and biopsy PPL but the level of adoption of these techniques by interventional pulmonologists (IPs) is unknown. This international survey was conducted to describe current practices in PPL investigation among IP. METHODS: This survey was sent to all members of the World Association for Bronchology and Interventional Pulmonology, Canadian Thoracic Society Procedures Assembly, AABIP, and the Groupe d'Endoscopie Thoracique et Interventionnel Francophone...
