সংজ্ঞা
Endoscopic ultrasonography (EUS) is used to view the walls of your digestive tract and other nearby organs. An ultrasound uses sound waves to make images of the inside of the body. In an EUS, the ultrasound probe is passed down the throat or up the rectum and into digestive tract.
পরীক্ষার কারণ
EUS may be used to:
- Diagnose or find the cause of a pain or abnormality in the digestive tract
- Locate and view tumors or abnormalities in the pancreas, bile ducts, and chest cavity
- Understand the extent of certain cancers and whether they have spread to lymph glands or other vital organs
- Take tissue samples ( biopsy) to diagnose a condition
- Provide needle aspiration (to drain a cyst)
সম্ভাব্য জটিলতা
Complications are rare, but no test is completely free of risk. If you are planning to have EUS, your doctor will review a list of possible complications, which may include:
- সংক্রমণ
- রক্তপাত
- Mild sore throat for 1-2 days
- Reaction to sedatives
- Regurgitation of stomach contents into the lungs
- Damage to digestive tract
জটিলতার ঝুঁকি বাড়াতে পারে এমন কারণগুলির মধ্যে রয়েছে:
- উন্নত বয়স
- Having other চিকিৎসাবিদ্যা শর্ত
পরীক্ষার আগে আপনার ডাক্তারের সাথে এই ঝুঁকিগুলি নিয়ে আলোচনা করতে ভুলবেন না।
কি আশা করছ
পরীক্ষার আগে
Leading up to the test, your doctor may instruct you to:
- Avoid eating or drinking (not even water) for at least six hours before the test.
- Take a special cleansing solution, laxative, or enema. This will clean out your intestines. You may also be asked to follow a clear liquid diet.
- Arrange for a ride home after the test if you have to take a sedative.
In most cases, it is okay to take aspirin and other blood-thinning medicines before the test. Ask your doctor if you take these medicines.
পরীক্ষার বর্ণনা
Your doctor may spray your throat with a local anesthetic. This will numb your throat, so you will not feel discomfort. You may also be given a sedative. This will help you to relax and reduce anxiety.
In most cases, you will lie on your left side. A thin, flexible tube, called an endoscope, will be inserted either through your throat or anus. The endoscope will have an ultrasound probe on the end of it. The ultrasound machine will create images of the digestive tract. When the imaging is done, your doctor will gently pull the endoscope out.
In some cases, the doctor might use the ultrasound to help take a biopsy or drain a cyst. If this happens, the doctor will insert tools through the endoscope to the area in question.
পরীক্ষার পর
After the test, you will recover in a special area. Your throat may be a little sore. Slight bloating is normal from the air and water that entered the digestive tract.
When you return home, do the following to help ensure a smooth recovery:
- Rest when you get home.
- When you feel ready, resume your normal diet.
- Wait until the sedative wears off before you operate machinery, drive, or make any major decisions. You may need to wait 24 hours.
- Take medicine as directed.
