Endoscopic ultrasound (EUS) is a procedure performed at Edward Hospital to produce images of the digestive tract and nearby organs from inside the stomach.
EUS is especially helpful in capturing images of hard-to-reach organs, such as the pancreas. Without this option, exploratory surgery is often needed to evaluate suspicious growths in these areas. Now people whose growths are benign can avoid surgery altogether.
Standard endoscopy uses a thin, flexible tube fitted with a tiny camera that is passed through the mouth down to the stomach. In EUS, an ultrasound device is inserted into this tube to obtain detailed images using high frequency sound waves.
EUS is the standard of care for staging esophageal, rectal and pancreatic cancers. Staging is the process of identifying how advanced and how aggressive someone's cancer is.
