EUS with FNA

What is EUS?
Endoscopic ultrasonography (EUS) allows your doctor to examine walls of your upper and lower gastrointestinal and extrinsic lesions in relationship to the gastrointestinal tract.

The upper tract consists of the esophagus, stomach and duodenum; the lower tract includes your colon and rectum. EUS is also used to study other organs that are near the gastrointestinal tract, including the lungs, mediastinum, liver, gall bladder, pancreas, adrenal glands, retroperitoneum and blood vessels. Endoscopists are highly trained specialists who welcome your questions regarding their credentials, training and experience. Your endoscopist will use a thin, flexible tube called an echoendoscope that has a built-in miniature ultrasound probe. Your doctor will pass the echoendoscope through your mouth or anus to the area to be examined. Your doctor then will use the ultrasound to use sound waves to create visual images of the digestive tract. Using ultrasound guidance, a thin needle can be advanced into these structures to obtain a sample of the tissue. This technique is known as a fine needle aspirate (FNA). The cells obtained from the FNA can be smeared on a slide and analyzed for abnormalities such as cancer. The cell analysis is called cytology.
Why is EUS done?
EUS provides your doctor with more information than other imaging tests by providing detailed images of your digestive tract. Your doctor can use EUS to diagnose certain conditions that may cause abdominal pain or abnormal weight loss. EUS is also used to evaluate known abnormalities, including lumps or lesions, which were detected at a prior endoscopy or were seen on x-ray tests, such as a computed tomography (CT) scan. EUS provides a detailed image of the lump or lesion, which can help your doctor determine its origin and help treatment decisions. EUS can be used to diagnose  diseases of the esophagus, stomach, duodenum, pancreas, bile duct, gallbladder and rectum when other tests are inconclusive or conflicting.
Why is EUS used for patients with cancer?
EUS helps your doctor determine the extent of spread of certain cancers of the digestive and respiratory systems. EUS allows your doctor to accurately assess the cancer’s depth and whether it has spread to adjacent lymph glands or nearby vital structures, such as major blood vessels. These results will determine the stage of the tumor and guide therapy. In some patients, EUS can be used to obtain a needle biopsy of a lump or lesion to help your doctor determine the proper treatment.

What can I expect during EUS?
Your doctor will talk to you regarding whether you need to fast, whether to take your current medications, and whether you have any allergies. You will receive sedatives intravenously to help you relax and sleep. You wil be lying on your left side. After you receive sedatives, your endoscopist will pass the ultrasound endoscope (echoendoscope) through your mouth, esophagus and stomach into the duodenum. The instrument does not interfere with your ability to breathe. The actual examination generally takes between 30-60 minutes. An EUS examination of the lower gastrointestinal tract can often be performed safely and comfortably with or without sedative medications. You will start by lying on your left side with your back toward the doctor. Most EUS examinations of the rectum generally take less than 45 minutes. You should know that if a needle biopsy of a lesion or drainage of a cyst is performed during the EUS, then the procedure will be longer and may take up to two hours. If you received sedatives, you will be monitored in the recovery area until most of the sedative 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 examination.You’ll be able to eat after you leave the procedure area, unless you’re instructed otherwise. Your doctor generally can inform you of the preliminary results of the procedure that day, but the results of some tests, including biopsies, may take several days.
