Procedures
EUS
- Endoscopic ultrasonography, or EUS, is used to examine the upper or lower part of the gastrointestinal tract. The upper GI tract includes the esophagus, stomach and first part of the small intestine, called the duodenum; the lower GI tract includes the colon, anus and rectum. EUS can also be used to examine other internal organs, such as the pancreas and gallbladder.
- EUS involves the use of an endoscope or colonoscope, long, thin, flexible tubes with a light and camera at the end, to help guide the scope throughout the duration of the procedure. However, these scopes are different than those used in colonscopy and ERCP: they emit sound waves that create visual images of the digestive tract that a normal endoscope cannot detect.
- EUS is used to aid in the diagnosis and treatment of various GI disorders. It may also be used to assess the nature of a tumor that may have been detected during a prior endoscopic procedure or CT scan. In conjunction with examination of a tissue sample obtained using a procedure called a “fine needle aspiration,” EUS can help diagnose diseases of the pancreas, gallbladder and bile duct The patient will remain comfortable during the procedure with the help of intravenous sedation. The drug will enable the patient to remain semi-conscious but comfortable throughout the procedure.
Patient preparation for the procedure
The procedure normally lasts about 45 minutes. Afterwards, the patient will wait in the recovery room while the anesthetic wears off. Once the medication dissipates, the patient may feel soreness in the back of the throat or some abdominal cramping and fullness depending on which type of scope was used during the procedure. Due to the lingering effects from the sedation, the patient cannot drive or work for the remainder of the day, and therefore must have a ride home.
