Advanced endoscopy

​Endoscopic ultrasound (EUS) is a state-of-the-art technology that combines endoscopy (a low risk diagnostic procedure involving insertion of a flexible tube which allows the doctor to see inside the intestinal tract) and ultrasound (also called sonography in which high-frequency sound waves is used to produce images of structures within your body).
