What is endoscopic ultrasound (EUS)?
Endoscopic ultrasound (EUS) allows your doctor to examine the lining and the walls of your upper or lower gastrointestinal (GI) tract. The upper tract is the esophagus, stomach and duodenum; the lower tract includes your colon and rectum. EUS is also used to study internal organs that lie next to the gastrointestinal tract, such as the gall bladder and pancreas.
Your doctor will use a thin, flexible tube called an endoscope that he or she will pass through your mouth or anus to the area to be examined. Your doctor then will turn on the ultrasound component to produce sound waves that create visual images of the digestive tract.
EUS provides detailed pictures of your digestive tract anatomy. EUS may be used to diagnose the cause of conditions such as abdominal pain or abnormal weight loss. EUS is also used to evaluate an abnormality, such as a growth, that was detected at a prior endoscopy or by x-ray. In addition, EUS can be used to diagnose diseases of the pancreas, bile duct and gallbladder when other tests are inconclusive.
What can I expect during EUS?
EUS of the Upper GI Tract
For EUS of the upper GI tract, you will be given medication at the beginning of the exam to help you relax and minimize discomfort or gagging. This medication will make you drowsy.
The doctor will insert an endoscope into your mouth and will advance it slowly through the esophagus, stomach and duodenum (the first part of your small intestine). The actual examination generally takes between 30 -60 minutes. Most patients consider it only slightly uncomfortable and may fall asleep during it. If abnormal tissue is found, the doctor may remove it through the endoscope for closer examination or biopsy.
EUS of the Lower GI Tract
EUS examination of the lower GI tract can often be performed safely and comfortably without medications, but you will probably receive a sedative if the examination will be prolonged or if the doctor will examine a significant distance into the colon.
You will start by lying on your left side and your doctor will inert an endoscope into the rectum and lower portion of the colon. Most EUS examinations of the lower GI tract last about 30 minutes. If abnormal tissue is found, the doctor may remove it through the endoscope for closer examination or biopsy.
What are the possible complications of EUS?
Although serious complications from EUS are rare, any medical procedure has the potential for risks. There is a slight risk of infection if fluid is removed from any cysts and antibiotics may be given as a preventative measure. Other risks include:
A nurse will review all potential warning signs with you before you leave the endoscopy center. The risk of complications slightly increases if a deep needle aspiration is performed during the EUS examination. There is also a small risk of infection if fluid is removed from any cysts, and antibiotics may be given to prevent this. These risks must be balanced against the potential benefits of the procedure and the risks of alternative approaches to the condition.
