It has opened the door for gastroenterologists to explore organs outside of the GI lumen, such as the lymph des, lung, pancreas, and liver. Endoscopic Ultrasound covers all aspects of endoscopic ultrasound, from the basics to the interventional indications. Richly detailed chapters describe the utility of EUS in different parts of the body and are organized based on body site Pioneers in the field summarize new studies, and the direction of EUS in practice. Endoscopic Ultrasound provides a ready reference that will help physicians and support staff that are beginning EUS, as well as trained ultrasographers who wish to arm themselves with a comprehensive reference and explore the future of the field.
