Abstract
The development of endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA)
technique has been proved to be a great armamentarium to gastroenterologists and other
branches including surgery, oncology, hepatology, pulmonary medicine, and internal
medicine. EUS-FNA is quite safe and allows tissue acquisition from difficult anatomical
locations like retroperitoneum, pancreas, and mediastinum. The current review discusses
basic techniques steps of EUS-FNA including tips and tricks. Also, false negative
FNA and EUS-FNA in difficult locations are discussed. We also discussed about EUS-guided fine needle biopsy.
