Endoscopic Ultrasound

An endoscopic ultrasound is an imaging procedure that doctors use to find and evaluate cancers and other conditions of the pancreas, liver, gallbladder and digestive tract.

During an EUS, a doctor inserts a thin plastic tube through your mouth or anus, depending on what part of your body needs to be examined. The tube, called an endoscope, is fitted with an ultrasound probe. This device uses sound waves to send pictures of the inside of your body to a screen nearby.

These detailed images help doctors determine the severity of the problem and the treatments most likely to work.

Why might I need an endoscopic ultrasound?

Doctors at Rush most often use endoscopic ultrasound to diagnose and evaluate the progression of these cancers:

  • Esophageal cancer
  • Lung cancer 
  • Stomach cancer
  • Pancreatic cancer

  • Rectal cancer 

They also sometimes use it to find and evaluate other conditions, including the following:

  • Barrett’s esophagus
  • Pancreatitis
  • Fecal incontinence
  • Nodules or polyps that may become cancer

Alternatives to endoscopic ultrasound

EUS provides doctors with more detailed images than many other diagnostic tests. But sometimes, for a variety of reasons, you might need other tests in addition to or instead of endoscopic ultrasound.

These may include the following:

  • Computed tomography (CT)
  • Magnetic resonance imaging (MRI)
  • Biopsy (examining a tissue sample) or surgical exploration
