You’ve been alluded to have an endoscopic ultrasonography, or EUS, which will enable your specialist, to assess or treat your condition. This handout will give you a fundamental comprehension of the system – how it is performed, how it can help, and what symptoms you may involvement. It can’t answer the majority of your inquiries, since a ton relies upon the individual patient and the specialist. If you don’t mind get some information about anything you don’t get it. Endoscopists are profoundly prepared masters who welcome your inquiries with respect to their qualifications, preparing and encounter

What is EUS?

Endoscopic ultrasound (EUS) is a minimally invasive procedure to assess gastrointestinal and lung diseases. During this procedure a  special endoscope is used with  high-frequency sound waves to make  detailed images of the lining and walls of your digestive tract and chest,  and also help in examining the nearby organs such as the pancreas and liver, and lymph nodes. During this procedure your doctor can examine as well as take biopsy for further analysis. EUS with fine-needle aspiration can be a minimally invasive alternative to exploratory surgery.

How EUS Helps Treat Cancer?

EUS helps doctors determine the extent of certain cancers of the digestive and respiratory systems and can accurately assess the cancer’s depth and whether it has spread to adjacent lymph glands. EUS can also be used to obtain biopsies to help your doctor determine the proper treatment.

How to Prepare for an EUS Procedure?

For  the upper gastrointestinal tract EUS,  you should have nothing to eat or drink for approximately six hours before the procedure. For EUS of the rectum or colon, your doctor will instruct you to either consume a large volume of a special cleansing solution or to follow a clear liquid diet combined with laxatives or enemas prior to the procedure.

Current Medications

You can take most medications as usual until the day of your EUS procedure. Tell your doctor about all of the medications that you are taking and any medication allergies you have. Anticoagulant medications (blood thinners such as Coumadin and Plavix) might need to be adjusted before your EUS procedure. Check with your doctor in advance regarding these prescriptions. On the morning of your exam, be sure to check with your doctor about which medications to take, and only take those essential medications with a very small cup of water. If you have an allergy to latex, inform your doctor prior to the test. Patients with latex allergies often require special equipment and might not be able to have an EUS examination.


Antibiotics aren’t generally required before or after an EUS procedure, but do tell your doctor if you take antibiotics before dental procedures. If your doctor feels you need antibiotics, they might be ordered during or after the EUS procedure to help prevent an infection. Your doctor might prescribe antibiotics if you’re having a specialized EUS procedure, such as to drain a fluid collection or a cyst using EUS guidance.

What to expect during EUS?

For an EUS exam of the upper GI tract, your endoscopist might spray your throat with a local anesthetic before the test begins. Usually, you will receive sedatives intravenously to help you relax. You will most likely begin by lying on your left side. After receiving sedation, your endoscopist will pass the scope through your mouth, esophagus and stomach into the duodenum. The instrument does not interfere with your ability to breathe. The actual exam generally takes between 15 and 45 minutes. Most patients consider it only slightly uncomfortable, and many fall asleep during the procedure. An EUS exam of the lower GI tract can often be performed safely and comfortably without medications. You will receive sedation if the procedure will be prolonged or if the doctor will examine a significant distance into the colon. You will start by lying on your left side with your back toward the doctor. Most EUS examinations of the rectum last from 10 to 30 minutes

What to expect after EUS?

Because you receive sedation, you will be monitored in the recovery area until most of the medication’s effects have worn off. If you had an upper EUS, your throat might be a little sore. You might feel bloated because of the air and water that were introduced during the procedure. You will be able to eat after you leave the procedure area, unless you are instructed otherwise. You won’t be allowed to drive after the procedure, even if you don’t feel tired. You should arrange for a ride home. You should also plan to have someone stay with you at home after the examination, because the sedatives could affect your judgment and reflexes for the remainder of the day. Your doctor will usually inform you of the results of the exam on the same day. However, some tests may take several days for the results to return. Possible Complications of EUS When doctors with specialized training and experience perform the EUS examination, complications are extremely rare. Bleeding might occur at the biopsy site, but it is usually minimal and rarely requires a follow up. You might have a slight sore throat for a day or so. Nonprescription, anesthetic-type throat lozenges can help soothe a sore throat. Other potential, but uncommon risks of EUS include a negative reaction to the sedative used, aspiration of stomach contents into your lungs, infection and complications from heart or lung diseases. One major, but very uncommon complication of EUS is perforation — a tear through the lining of the intestine that might require surgery to repair. The possibility of complications will increase slightly if a deep needle biopsy is performed during the EUS examination. All of these risks must be balanced against the potential benefits of the procedure and the risks of alternative approaches to the condition.
