Endoscopic Ultrasound (EUS) is a minimally invasive procedure that provides the most accurate medical images currently available of the gastrointestinal tract wall and helps to diagnose and treat many gastrointestinal cancers such as pancreatic, esophageal, gastric, ampullary, and cholangiocarcinoma, as well as other difficult problems encountered by surgeons, radiologists, oncologists, and internists.
- Low risk level — below 1%
- Procedure takes only 20-40 minutes
- Easy and safe
It can also be combined with other GI procedures, including ERCP, to provide staging information for mediastinal, esophageal, gastric, pancreatic, and rectal tumors. An endoscopic ultrasound is an endoscopic procedure where a long, thin, flexible tube or "scope" is placed into either the mouth or in the rectum. The scope has a light and a camera on its tip which allows the physician to examine the lining of the esophagus, stomach, first portion of the small intestine, or the colon.
In addition to visualizing the intestine like a regular endoscope, the EUS scope also has an ultrasound probe which allows the physician to examine the gastrointestinal tract with ultrasound. The ultrasound allows the physician to examine the different layers of the intestinal wall as well as other organs within the body.
An endoscopic ultrasound may be performed to evaluate abnormalities in the wall of the intestine or abnormalities in other organs such as the pancreas, biliary system, and chest. Additionally, the EUS is often used to help stage various cancers.
