EUS stands for Endoscopic Ultrasound. This is a highly specialized procedure that enables us to more closely examine and sometimes sample the walls of the intestinal tract as well as adjacent organs such as the liver, pancreas, and gallbladder. EUS allows for highly accurate and minimally invasive diagnosis of various gastrointestinal tumors and pancreatic cysts. The Procedure: The procedure time may vary depending on the complexity of the case. Most patients should expect to receive IV anesthesia and while asleep a flexible tube containing an ultrasound tip is inserted through the mouth and advanced to examine and sometimes biopsy the area of interest. After the Procedure: Your doctor may be able to discuss the test results with you right after the procedure. Alternatively, you may need to discuss the findings in greater detail at the time of your next office visit. Typically you may go home the same day or spend the night in the hospital for observation. Follow these tips: • You can return to a normal routine and diet the day after the EUS. • If a biopsy was taken, you may need to avoid blood-thinning medications such as aspirin for 5-7 days. • In some instances after biopsy, 3-5 days of oral antibiotics may be prescribed. • Call your doctor right away if you have fever or abdominal pain. They may be signs of a developing infection.
