An upper endoscopy may be a procedure to visually examine your upper gastrointestinal system with a small camera on the top of an extended, flexible tube. A specialist in diseases of the gastrointestinal system (gastroenterologist) uses endoscopy to diagnose and, sometimes, treat conditions that affect the esophagus, stomach, and beginning of the tiny intestine.
The medical term for an upper endoscopy is esophagogastroduodenoscopy. you’ll have an upper endoscopy wiped out at your doctor’s office, an outpatient surgery center, or a hospital.
What Is An Upper Endoscopy?
An upper endoscopy may be a procedure a doctor uses to see at the inner lining of the upper alimentary canal (the esophagus, stomach, and duodenum, which is the first part of the tiny intestine). This test is additionally sometimes called EGD.
This procedure is completed with an endoscope, a thin, flexible tube with a light-weight, and a little video camera on the top. The tube is put in through your mouth, down your throat, and into your esophagus, stomach, and little intestine.
Why Does One Need An Upper Endoscopy?
There are a couple of reasons you would possibly need an upper endoscopy Which is given below:
You Are Having Problems With Your Upper Alimentary Canal
This test often wants to search for the causes of problems within the esophagus, stomach, or duodenum. it’d be done due to symptoms you’re having (such as trouble swallowing, heartburn, feeling full quickly, or expulsion or vomiting blood). Or it’d be done to seem at an abnormal area seen on an imaging test (such as an x-ray or CT scan).
An upper endoscopy is often done as a part of endoscopic ultrasound to see at the wall of the alimentary canal, also as for nearby lymph nodes and other structures just outside the alimentary canal. for instance, if there’s a tumor within the wall of the esophagus or stomach, ultrasound can show how far it’s grown into (or through) the wall, and if it’d have reached the nearby lymph nodes. From the tiny intestine, endoscopic ultrasound also can be wont to check out the pancreas, gallbladder, or bile ducts.
For this test, an endoscope is fitted with a little ultrasound probe on its tip. it’s passed down into the alimentary canal and may be pointed in several directions to seem at the wall and nearby lymph nodes and other structures. The ultrasound gives off sound waves and picks up the echoes as they bounce off these structures, and therefore the echoes are converted into a picture on a display screen. If suspicious areas like enlarged lymph nodes are seen, a hollow needle is often skilled in the endoscope into these areas to get a biopsy.
An upper endoscopy is often used alongside x-rays to see at (and sometimes treat problems in) the pancreas and bile ducts. This sort of procedure is understood as endoscopic retrograde cholangiopancreatography (ERCP).
For this test, a doctor passes an endoscope down into the primary part of the tiny intestine. A little catheter (tube) is then put through the endoscope and into the common bile duct, and a little amount of contrast dye is injected through the catheter. The dye helps outline the bile and pancreatic ducts as x-rays are taken, and may show if there are blockages. The doctor also can take biopsy samples of tissue or fluid during an ERCP.
Why It’s Done
An upper endoscopy is employed to diagnose and, sometimes, treat conditions that affect the upper part of your gastrointestinal system, including the esophagus, stomach, and beginning of the tiny intestine.
Your Doctor May Recommend An Endoscopy Procedure To:
Investigate symptoms: An endoscopy may help your doctor determine what’s causing digestive signs and symptoms, like nausea, vomiting, abdominal pain, difficulty swallowing, and gastrointestinal bleeding.
Diagnose: Your doctor may use endoscopy to gather tissue samples (biopsy) to check for diseases and conditions, like anemia, bleeding, inflammation, diarrhea, or cancers of the gastrointestinal system.
Treat: Your doctor can pass special tools through the endoscope to treat problems in your gastrointestinal system, like burning a bleeding vessel to prevent bleeding, widening a narrow esophagus, clipping off a polyp, or removing a far-off object.
An endoscopy is usually combined with other procedures, like an ultrasound. An ultrasound probe could also be attached to the endoscope to make specialized images of the wall of your esophagus or stomach. Endoscopic ultrasound can also help your doctor create images of hard-to-reach organs, like your pancreas. Newer endoscopes use high-definition video to supply clearer images.
Many endoscopes allow your doctor to use a technology called narrow-band imaging, which uses a special light to assist better detect precancerous conditions, like Barrett’s esophagus.
You Have A Suspicious Area Which May Be Cancer
An upper endoscopy often wants to take biopsy samples of the esophagus, stomach, or intestine (to determine if an abnormal area may be cancer, for example). This is often done by passing long, thin instruments, like small forceps (pincers), down through the center of the endoscope to gather the samples. The samples are then checked out within the lab.
You Have A Gastrointestinal System Problem that Must Be Treated
An upper endoscopy is often wont to treat a blocked part of the alimentary canal or other sorts of problems. For instance, a little laser placed on the top of an endoscope often won’t turn away a part of a tumor that’s blocking the passage of food. Or an endoscope is often wont to place a rigid tube called a stent into a neighborhood of the alimentary canal to assist keep it open.
What’s It Wish to Have An Upper Endoscopy?
This is a general outline of what typically happens before, during, and after upper endoscopy. But your experience could be a touch different, counting on why you’re having the test, where you’re having the test done, and your overall health. make certain to speak to your health care provider before having this test so you understand what to expect, and ask questions if there’s anything you’re unsure about.
Before The Test
Be sure your health care provider knows about any medicines you’re taking, including vitamins, herbs, and supplements, also as if you’ve got allergies to any medicines.
You may be asked to prevent taking blood-thinning medicines (including aspirin) or other medicines for several days before the test. you’ll likely be told to not eat or drink anything for a minimum of several hours before the procedure. Your doctor or nurse will offer you specific instructions. make certain to follow them, and to ask questions if there’s anything you don’t understand.
Because a sedative is employed to assist you easier during the test, you’ll presumably get to arrange for a ride home after the test. you would possibly need someone to assist you to get home if you’re sleepy or dizzy, numerous centers won’t discharge people to travel range in a cab or a ridesharing service. If transportation could be a drag, talk together with your health care provider about the policy at your hospital or surgery center for using one among these services. There could also be other resources available for getting home, counting on things.
Getting The Test
An upper endoscopy can usually be done as an outpatient procedure (where you don’t gotta stay overnight during a hospital).
For this test, you’ll lie on your side or back on an exam table. Your mouth and throat could be sprayed first with numbing medicine, otherwise, you might get a liquid medicine and be asked to gargle with it. you would possibly even be given a sedative through an intravenous (IV) line to form you are feeling relaxed. Less often, you would possibly be asleep (under general anesthesia) for the test. you would possibly get a mouthpiece to carry your mouth open during the procedure. The scope will then be passed down through your throat, but it won’t affect your breathing. Air is usually put into the stomach through the scope to form it easier to ascertain.
The procedure usually takes about 15 to half-hour, but it’d take longer, counting on what’s being done.
After The Test
After the procedure, you’ll be watched closely to form sure you don’t have any complications. If you bought a sedative, you would possibly not remember the procedure.
Because air is usually put into your stomach as a part of the procedure, you would possibly feel bloated or crampy afterward.
Your mouth and throat will probably be numb for a few hours. you will not be allowed to eat or drink until the numbness wears off. Once the numbness is gone, you’ll have pharyngitis, cough, or hoarseness for the subsequent day approximately.
If you had the procedure as an outpatient, you’ll probably be ready to head home after a couple of hours, but you’ll likely need a ride home due to the medicines or anesthesia you received. Your doctor or nurse should offer you specific instructions on what you’ll and can’t neutralize the hours after the test.
If biopsies were done as a part of the procedure, the results will typically be available within a couple of days, although some tests on the biopsy samples might take longer. you’ll have to follow up with your doctor after the procedure to urge your results.
Possible Complications of Upper Endoscopy
Upper endoscopy is typically safe, but there’s a little risk of:
- Bleeding from an area where the doctor removed tissue samples
- Perforation (puncture) of the liner of the alimentary canal
- Reactions to anesthesia
