Core Tip
Core Tip: Intra-abdominal lymphadenopathy due to tuberculosis (TB) poses a significant diagnostic challenge primarily due to difficulty in tissue acquisition. Endoscopic ultrasound guided fine needle aspiration/biopsy (EUS-FNA/B) has shown promise in the evaluation of TB presenting with mediastinal lymph nodes; however, its role in intra-abdominal lymphadenopathy due to TB remains unclear. In this study, a large cohort of patients who underwent EUS-FNA/B were studied. EUS-FNA/B was found to have a sensitivity and specificity of 86% and 93%, respectively, with a high diagnostic accuracy of 88% in the evaluation of intra-abdominal lymphadenitis due to TB. This study provides valuable data on the pivotal role of EUS-FNA/B in the evaluation of this difficult sub-group of patients. However, the validity of these findings in populations with low prevalence of TB needs further evaluation.
