[Recent advances and practical clinical applications of endoscopic ultrasound]

The role of endoscopic ultrasound (EUS) is in a constant state of evolution. Newer and more sophisticated imaging methods contrast very favorably to EUS and questions arise as to the real utility and even the existence of this method. Recent work has aimed to establish the actual role of EUS in this context and to establish its rightful place in the endoscopist's armamentarium. Limited information about this method, the indications, contraindications, virtues and limitations is an obstacle against widespread adoption not only in our country. Furthermore, the cost of the equipment and the long learning curve conspire to slow the implementation of EUS. In this paper we review the most recent developments in equipment and procedures as well as analyze the established role of EUS in clinical practice from recent literature.
