flexible bronchoscopy

Tooth aspiration, while commonly linked to predisposing conditions such as loose teeth, facial surgeries, or injuries, can also affect patients without apparent risk factors. Such small foreign body aspirations may go undiagnosed for many months as patients often tolerate the symptoms, such as chronic cough. However, the protracted course of unaddressed foreign body aspiration has the potential to resemble symptoms of malignancy, including persistent hemoptysis, weight loss, and fatigue. In this report, we detail the case of a 51-year-old man with underlying chronic obstructive pulmonary disease (COPD) whose history and symptoms initially suggested lung carcinoma...

BACKGROUND: IgG4-related disease is a systemic fibroinflammatory disease that is mainly seen in older men, and involves multiple organs, such as the pancreas and lungs. However, 75% of patients with IgG4-related lung disease are asymptomatic (if they are symptomatic, they mainly complain of nasal congestion, rhinorrhoea, chest pain, and cough) and are incidentally diagnosed through chest computed tomograph. Although, nodules in the airway and bronchial wall thickening are criteria for diagnosis, it is important that nodules have been reported in peripheral airways in several cases and rarely in the central airway...

Foreign body aspiration (FBA) in adults is indeed a significant medical concern, albeit less common than in children. The increase in incidence with advancing age can be attributed to factors such as a decline in mental status and impairment of the swallowing reflex, which is more prevalent in the elderly population. The symptoms of FBA are highly variable, ranging from severe, acute asphyxiation, which may or may not involve complete airway obstruction, to more subtle signs like coughing, shortness of breath (dyspnea), choking, or fever...

OBJECTIVES: To make recommendations on the diagnosis and treatment of post-extubation laryngitis (PEL) in children with or without other comorbidities. METHODS: A three-iterative modified Delphi method was applied. Specialists were recruited representing pediatric otolaryngologists, pediatric and neonatal intensivists. Questions and statements approached topics encompassing definition, diagnosis, endoscopic airway evaluation, risk factors, comorbidities, management, and follow-up...

INTRODUCTION: While awake tracheal intubation (ATI) is regarded as the gold standard for difficult airway management according to current guidelines, there seems to be a reluctance in its application. This retrospective cohort study, conducted at a German tertiary hospital over a 2-year period, aimed to demonstrate that integrating awake tracheal intubation using flexible bronchoscopy (ATI:FB) into routine airway management makes it a successful and safe approach. MATERIALS AND METHODS: In 2019 and 2020, records from the data acquisition system (DAQ) and archived anesthesia records were screened to evaluate the specifics of ATI:FB procedures, focusing on overall success and safety...

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...

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...

BACKGROUND: In flexible bronchoscopy, endobronchial ultrasonography using a guide sheath (EBUS-GS) has varying diagnostic yield depending on the findings of radial-endobronchial ultrasonography (R-EBUS). The diagnosis rate is lower when the ultrasound probe is "adjacent to", than when it is "within" the lesion. However, these findings are inconsistent, and the imaging status may change from "adjacent to" to "within" as examination progresses. In this study, we analyzed the predictive factors for this change, which remain unexplored till date...

INTRODUCTION AND IMPORTANCE: Pneumocystis jirovecii (PJP) pneumonia is a serious life-threatening condition in immunocompromised individuals and is often associated with human immunodeficiency virus (HIV) + patients. We describe a case of PJP pneumonia which provided a diagnostic challenge in a patient who presented with no known risk factors leading to a delay in initiation of appropriate antibiotic therapy. CASE PRESENTATION: A 71-year-old previously healthy white/Caucasian male presented with subacute hypoxic respiratory failure due to multifocal pneumonia with diffuse bilateral ground glass opacities with consolidations despite prior treatment with antibiotics and steroids...

BACKGROUND: Patients with relapsing polychondritis (RP) sometimes experience upper airway collapse or lower airway stenosis, and bronchoscopy may provide a valuable typical image to confirm the diagnosis. This study aimed to identify potential risk factors associated with severe adverse effects during bronchoscopy. METHODS: We performed a retrospective cohort study of 82 consecutive patients with RP hospitalized at Peking Union Medical College Hospital between January 1, 2012 and December 31, 2022...

BACKGROUND: Differential diagnosis of mediastinal lymphadenopathy is an issue of debate. Lymph nodes may be enlarged due to a variety of inflammatory, infectious, or malignant reasons. Therefore, obtaining samples from the affected nodes is crucial for the diagnosis. Usually, these patients are subjected to TBNA (EBUS or conventional) or mediastinoscopy if TBNA is not conclusive. This study evaluated the safety and feasibility of this new technique of transbronchial forceps biopsy for the diagnosis of mediastinal lymphadenopathy...

INTRODUCTION: Difficult intubation is the situation when a skilled anesthetist has difficulties to manage airway using face mask, laryngoscopy, supraglottic device, tracheal intubation, surgery. Videolaryngoscope and flexible fibroscope (FFS) represent valid alternatives for difficult airway management, with some limitations. However, literature lacks of studies about the efficacy of the combined use of videolaryngoscope and FFS. CASE REPORT: We report a case of a man, with glottic lesion, who needs surgery under general anesthesia...

INTRODUCTION: In transbronchial biopsy of peripheral pulmonary lesions, the bronchoscope can reach only a limited depth due to the progressive narrowing of bronchi, which may reduce the diagnostic rate. This study examined the balloon dilatation for bronchoscope delivery (BDBD) technique, employing a novel balloon device to enhance bronchoscopy into the peripheral lung areas. METHODS: Anaesthetised swine served as our primary model. Using computed tomography (CT) scans, we positioned virtual targets characterised by a positive bronchus sign and a diameter of 20 mm beneath the pleura...

Tuberculous tracheobronchial fistulas are caused by mediastinal or hilar tuberculous lymph nodes ulcerating into the trachea or bronchus. Patients usually require flexible bronchoscopic interventional procedures in addition to systemic anti-tuberculosis chemotherapy in the ulceration phase. In this paper, we reported 2 cases of central airway stenosis caused by tuberculous tracheobronchial fistula, which had poor treatment results after flexible bronchoscopy. According to the patients' condition, the airway lesions were treated by rigid bronchoscopy combined with flexible bronchoscopy, cryotherapy, argon plasma coagulation, and so on...

A 37-year-old man presented with chronic cavitary pulmonary aspergillosis and hemoptysis refractory to systemic antifungal therapy with voriconazole and bronchial artery embolization. Surgical excision was unfeasible due to the patient's refusal of blood transfusions. Ten sessions of intracavitary instillation of amphotericin B via flexible bronchoscopy were then performed. Hemoptysis cessation and aspergilloma resolution were achieved, with no toxicity or side effects, and the clinical benefits were sustained at six months of follow-up...

BACKGROUND: There have been several reports demonstrating the safety of flexible bronchoscopy (FB) in the elderly, but none have focused specifically on lung cancer, which is a frequent biopsy procedure. METHODS: In this study, we retrospectively evaluated the safety of FB and subsequent treatment in elderly patients with suspected primary lung cancer. Elderly patients were defined as 75 years of age or older. RESULTS: A total of 141 patients, 77 in the elderly group and 64 in the nonelderly group, were reviewed...

The purpose of this study is to evaluate the cell lines seen on esophagogastoduodenoscopy (EGD) of children who have difficulties feeding, esophageal fistula, and asthma that has some histologic abnormalities.  This is a study that looked back at the medical records of 100 children whose cells had been surgically restored after being impacted by EA or TEF. A review of the instrumental tests that were carried out at our facility has been conducted in order to identify any lingering anatomic or functional abnormalities of the airways and gastrointestinal system that would explain the pulmonary clinical images...

BACKGROUND: Pathology is considered the gold standard for the diagnosis of lung lesions, but the pathological result is relatively lagging and cannot provide real-time guidance for the biopsy procedure. OBJECTIVE: To investigate the potential application of rapid on-site evaluation (ROSE) during flexible bronchoscopy (FB) in the evaluation and diagnosis of lung lesions. PATIENTS AND METHODS: Consecutive patients who underwent FB for the diagnosis of lung lesions between August 2022 and February 2023 were included in this retrospective study...

Pneumoperitoneum is most commonly caused by perforation of a hollow viscus but can also result as an extension of pneumothorax and/or pneumomediastinum. We present a case of pneumoperitoneum preceded by intraprocedural hemoptysis and tension pneumothorax that developed during transbronchial needle aspiration using robot-assisted flexible bronchoscopy. After stabilization and management of the pneumothorax, diagnostic laparoscopy was performed and revealed no evidence of diaphragmatic or intra-abdominal perforation but showed diffuse emphysematous changes in the gastrohepatic ligament, small and large bowel mesentery, and preperitoneal space...
