Endoscopic ultrasound (EUS) is a minimally invasive procedure that gastroenterologists use to evaluate and diagnose diseases affecting the digestive (GI) system and lungs. The EUS uses a special type of endoscope to produce sound waves to create detailed images of the digestive tract and chest as well as nearby organs like the pancreas, liver, and lymph nodes.
Your doctor may recommend endoscopic ultrasound if you have abdominal pain or other symptoms of a GI condition such as cancer, pancreatitis, pancreatic cysts, Barrett’s esophagus, bile duct stones, or sarcoidosis.
Before the procedure, you’ll need to follow the instructions your doctor gives you carefully. Make sure your doctor knows about all medications you are on so they can tell you if and when you should stop taking them before the endoscopic ultrasound.
You need to have a completely empty stomach so you’ll be asked to fast for at least 6 hours before the test. In the cases of rectal EUS, you’ll need to clear the bowel, so your doctor may tell you to take a laxative and/or follow a liquid diet before the procedure.
You will be given IV sedatives or other medication to help you relax for the procedure. You may also be given a local anesthetic for your throat before the test.
During EUS, you will lie on your side as the doctor passes a thin, flexible tube called an endoscope through the mouth and through the digestive tract. An ultrasound device in the scope creates soundwaves that create detailed pictures of the digestive tract. The scope is then gradually withdrawn.
Endoscopic ultrasound is a safe procedure with a low risk of complications when performed by the experts at Wake Endoscopy Center. In rare cases, complications include bleeding, infection, and perforation.
If you were sedated for the procedure, you will be monitored in the recovery until the sedative has worn off. You may have some soreness in your throat and you may feel a bit bloated. Unless you are given other instructions, you will be able to eat and drink after you leave. You must have someone come with you and stay through the procedure to drive you home.
Your gastroenterologist will analyze the images produced during EUS and report the results to you. Then you will discuss the findings and go over any necessary next steps.
Yes. Because of the sedation used during EUS, all patients must have a driver who is over the age of 18 to drive them home from their procedure. The driver MUST remain in the building and stay on-site for the entire duration of the procedure.
