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.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
