Endoscopic Ultrasound

A method that our gastroenterologists can use to assess the health of your digestive tract is endoscopic ultrasound. Used to diagnose a variety of problems your digestion may be facing, this procedure is another one of Kalamazoo Gastroenterology Hepatology’s thorough ways to ensure that you are properly diagnosed with your digestive health.

What is endoscopic ultrasound?

Endoscopic ultrasound (EUS) is a procedure to assess gastrointestinal diseases. A special endoscope is used to produce detailed images of the lining and walls of your digestive tract and organs nearby, mainly the pancreas, liver, and lymph nodes.

What to expect for endoscopic ultrasound.

After you have checked in for your outpatient procedure, you will be given medication to help you relax for the EUS. During the procedure, the doctor will pass a thin, flexible tube (endoscope) through your mouth and your digestive tract. The tube contains a transducer that produces sound wave that creates an image of surrounding tissue. During the procedure a fine needle aspiration (FNA) may be done on lymph nodes, tumors or other abnormalities that are noted either during the exam or from previous radiology studies, such as a CT scan or MRI. FNA will extract fluid and tissue for analysis, then this sample is sent to pathology to evaluate. FNA will use a second curved device that is placed through a channel in the endoscope. The endoscope is then gradually withdrawn.

EUS is generally safe when performed at a center or hospital and you have followed the instructions for preparing for the EUS. The doctor will discuss the risks associated with EUS. Risks may include: Bleeding, infection, tearing (perforation) of the intestinal wall and pancreatitis if FNA is done on the pancreas.
