Endoscopic Ultrasound (EUS)

Endoscopic Ultrasound (EUS) is a minimally-invasive procedure used to assess digestive (GI) and diseases. This technology uses high-frequency sound waves to produce detailed images of the lining and walls of your GI tract and nearby organs, such as the pancreas and liver.

How EUS Works

A thin, flexible tube (endoscope) is inserted into the mouth or rectum and passed to the stomach and duodenum (top part of the small intestine). The end of the endoscope has an ultrasound probe that emits sound waves to produce images of your digestive tract and surrounding organs. EUS can also be combined with fine-needle aspiration procedures, allowing doctors to biopsy fluid and tissue from the abdomen or chest for analysis. EUS is a minimally-invasive alternative to exploratory surgery.
