Abstract
Introduction: This study presents the experience with linear endobronchial ultrasound (EBUS-L) in the Interventional Respiratory Endoscopy Unit of Hospital Maciel from November 2019 to February 2023.
Methods: A total of 122 procedures were analyzed, with the primary objective of EBUS being the staging and diagnosis of bronchopulmonary cancer, which accounted for 49.1% of the cases.
Results: The analysis focused on the correlation between malignant etiology and two main variables: the size of the lymphadenopathy and its standardized uptake value (SUV). Notably, a high rate of adequate samples (98.4%) was achieved and a statistically significant relationship was found between lymphadenopathy ≥ 15 mm, an SUV in PET-CT ≥ 3.75, and malignant etiology.
Conclusion: The findings indicate that EBUS-L is an effective tool for the staging and diagnosis of bronchopulmonary cancer, particularly in cases with larger lymphadenopathy and elevated SUV values.
