At Banner Gateway Medical Center, we leverage state-of-the-art technologies and the latest medical procedures to diagnose, biopsy, stage and treat a wide range of digestive health conditions.
Endoscopic ultrasound (EUS), a combination of traditional endoscopy and ultrasound, is a procedure invaluable in the diagnosis, staging and treatment of conditions such as:
- Pancreatic Cancer
- Rectal or low Colon Cancers
- Liver Cancer
- Lung Cancer
- Unexplained Abdominal Pain
- Unidentified lumps in the stomach
The EUS procedure
During EUS, a long flexible tube known as an endoscope is pushed over the tongue and past the esophagus and stomach to give physicians access to the entire digestive tract, including the individual layers of the intestinal lining, surrounding tissues and nearby organs.
With a small ultrasound transducer mounted to the tip of the device, physicians can view the area with greater detail and clarity than using traditional ultrasound.
EUS has proven effective in identifying tumors missed using computed tomography (CT) and magnetic resonance imaging (MRI) testing due to size and/or location.
EUS can also pinpoint the exact layer in which a tumor begins, a level of detail not available through CT and MRI.
The precision that comes with EUS capabilities helps physicians make the most informed treatment planning decisions. This technology also allows for on-the-spot removal of benign polyps, injection of markers to help guide radiation oncologists or, in some cases, even the injection of chemotherapy directly into tumors to spare healthy surrounding tissue, when appropriate.
Patients who are deemed candidates for EUS are sedated during the procedure to minimize any associated pain or discomfort. Therefore, they are generally required to fast for six hours prior to having the procedure performed, though only a simple enema may be needed in some cases.
