Abstract: OBJECTIVES:To disseminate transesophageal ultrasound-guided fine needle aspiration (EUS-FNA) as an alternative to investigate mediastinal tumoral lesions because it is an underused modality that has been available in Brazil for more than 15 years.METHODS:Descriptive analysis of a single endoscopy service's experience since 1997 in the accomplishment of EUS-FNA for mediastinal staging of previously known malignancies (Group 1) or diagnostic definition of suspect lymph nodes and masses (Group 2).RESULTS:EUS-FNA … Show more

“…Since endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for a pancreatic tumor was first reported in 1992 [1], it has been applied to many targets, such as subepithelial lesions of the gastrointestinal tract, mediastinal masses, biliary tumors, and ascites [2-12]. EUS-FNA can also be useful for diagnosing internal lymphadenopathy, which often requires correct diagnosis to confirm the cancer stage, recurrence of surgically resected malignancy, and non-neoplastic lymph nodes.…”

“…EUS-TA offers the power to acquire tissue from the middle and posterior mediastinum along the esophagus for cytohistological study with significant accuracy and safety [12,13,18,[39][40][41][42][43][44][45]. A study that compared the usefulness of EBUS-TBNA versus EUS-FNA in the diagnosis of mediastinal lesions under suspicion of malignancy did not uncover differences between the two procedures, and by combining them, researchers achieved nearly 100% accuracy [12].…”

“…The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EUS-FNA in the diagnosis of mediastinal malignancies was 75%, 100%, 100%, 67%, and 83%, respectively. In a different study by Ardengh et al (2011), EUS-FNA was undertaken in 51 patients with ages ranging from 26–87 years, and lesion diameters of; 1.1–9.8cm (mean, 3.9 cm) [18]. EUS-FNA was employed to diagnose 22 neoplasms, 5 cases of tuberculosis, and two duplication cysts.…”
