Background: Even though studies have indicated the usefulness and safety of endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA), elderly patient data are limited due to the small sample sizes.
Aim: We aimed to evaluate usage and safety of EBUS-TBNA in elderly population.
Methods: This single-center retrospective study was conducted with patients who underwent an EBUS-TBNA procedure between September 2011 and December 2019. The patients were categorized into two groups: those aged 65 years or older (elderly group) and those younger than 65 years (younger group).
Results: 2444 patient data, 1069 of which were in the elderly group, were analyzed. The cytological examination of EBUS-TBNA identified specimen adequacy in 96.8% of patients. One hundred and thirty patients (5.3%) experienced complications, with similar complication rates recorded in both the elderly and younger groups (5.4% vs 5.2%, p: 0.836). Logistic regression analyses revealed that age, and presence of hypertension, diabetes mellitus, coronary artery disease and malignancy are associated significantly with complication-related EBUS-TBNA. For the lymph nodes with a final diagnosis of malignancy, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of EBUS-TBNA revealed a diagnostic performance in excess of 90% except for metastasis and lymphoma.
Conclusion: EBUS-TBNA can be considered a safe and effective technique in patients aged 65 years and over.

Follicular Lymphoma Diagnosed Successfully via Endobronchial Ultrasound-Guided Intranodal Forceps Biopsy Located in Left Lymph Node #12.

A 71-year-old man with follicular lymphoma of the right inguinal lymph node was referred to our hospital owing to mediastinal lymph node enlargement (left #12). The patient had a history of cyclosporine (CYS-A) and steroid therapy for fibrotic hypersensitivity pneumonitis. Endobronchial ultrasound-transbronchial aspiration and endobronchial ultrasound-guided intranodal forceps biopsy (EBUS-IFB) were performed under conscious sedation using midazolam and fentanyl.

Background: There are two approaches for endobronchial ultrasound (EBUS) training: the traditional apprenticeship approach involving 'see one, do one, teach one', and the computer-based simulation approach. In the traditional approach, the trainee learns under direct supervision from an expert preceptor while performing on patients. In the latter approach, trainees use a high-fidelity bronchoscopy simulator, undertake a skills assessment exam (Endobronchial Ultrasound Skills and Task Assessment Tool (EBUS-STAT)), and receive supervised patient-based training from experienced clinicians.

Introduction: During endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA), a saline-filled balloon placed over the tip of the bronchoscope is used to improve coupling of the ultrasound transducer to the airway wall. However, it is unknown whether it objectively improves image quality or affects procedural outcomes. Our aim was to establish whether the use of a balloon during EBUS impacts image quality, diagnostic yield, procedure duration or complications.

Objective: Endobronchial ultrasound elastography produces a color map of mediastinal lymph nodes, with the color blue (level 60) indicating stiffness. Our pilot study demonstrated that predominantly blue lymph nodes, with a stiffness area ratio greater than 0.496, are likely malignant.

Background: Endobronchial ultrasound-guided transbronchial aspiration (EBUS-TBNA) has become the standard for initial lung cancer diagnosis and staging. Previous guidelines have generally focused on the "when" and "how" of EBUS-TBNA; however, little guidance is available on handling and processing specimens during and after acquisition to help optimize both diagnostic yield and tissue integrity for ancillary studies. This document examines the available literature on EBUS-TBNA specimen processing and handling.
