Summary

Endoscopic ultrasonography (EUS) is an established diagnostic and therapeutic modality in gastroenterology. Although most gastroenterologists are not trained in the practice of EUS, it is important that they understand the principles of the technique and the indications for EUS in order to offer optimal patient care. This chapter provides case vignettes with selected images that illustrate common diagnostic and therapeutic indications for EUS. A brief overview of the role of EUS in such indications is included. As a complete representation of images encountered in endosonography, the authors recommend that anyone interested in learning EUS should review textbooks dedicated to the practice of EUS and seek out an established EUS training program.
