title: Endoscopic ultrasound-guided fine-needle aspiration cytology for diagnosis above and below the diaphragm.
abstract: Endosonography ultrasound (EUS) is a minimally invasive technology using a high-frequency ultrasound transducer that is incorporated into the tip of a conventional endoscope. This technique permits high-resolution imaging of the gastrointestinal wall and structures in its vicinity, as well as real-time endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA). This is a review of the literature on EUS-guided FNA of the mediastinal and abdominal lymph nodes, the pancreas, intramural gastrointestinal masses, and other miscellaneous organs and body cavities. EUS-guided FNA is a recently developed procedure that has established itself as a safe, highly accurate, and clinically useful modality.
