Endoscopic ultrasound for esophageal cancer

What is an endoscopic ultrasound?

Endoscopic ultrasound (EUS) is an imaging procedure which uses an endoscope (a long, flexible, lighted tube with an attached camera), along with ultrasound waves, to examine internal parts of the body and produce images of surrounding tissues.

The endoscope (with a transducer on its tip) is inserted into a body cavity (such as the mouth) in order to get close to the organ(s) being examined to obtain detailed pictures. EUS is commonly used to diagnose and stage gastrointestinal (digestive tract) diseases, such as esophageal cancer.

EUS for esophageal cancer

An EUS allows our doctors to see the esophagus and surrounding tissues on an ultrasound machine. This test for esophageal cancer is effective in detecting abnormalities in the surrounding tissue and lymph nodes. An EUS also helps stage esophageal cancer, which predicts treatment and prognosis.
