What Is an Upper Endoscopy?
An upper endoscopy is a procedure to help diagnose problems in your throat or esophagus, stomach, and first portion of the small intestine. The doctor uses an endoscope, which is a long, thin, flexible tube with a light at the end of it. Using upper endoscopy can help you avoid the need for exploratory surgery. In addition to diagnosing possible problems, the doctor can perform minor procedures during an endoscopy. Examples include taking biopsies, removing polyps, and treating bleeding.
Why Might the Doctor Recommend an Upper Endoscopy?
An upper endoscopy can help diagnose and better understand a variety of problems. They include the following.
- Gastroesophageal reflux disease (GERD).
- Barrett’s esophagus.
- Hiatal hernia.
- Cancers.
- Ulcer.
These are additional reasons to have an upper endoscopy.
- Determine the reason for an infection or unexplained bleeding.
- Figure out why you are having trouble swallowing or have abdominal bloating.
- Follow-up after surgery in the stomach area.
- Discover the reason why you are vomiting blood.
- See whether your stomach ulcers are healing as they should.
What Should I Expect During My Procedure?
To prepare for your upper endoscopy, you need to fast for at least 6 to 8 hours before the test. Your doctor may have you stop taking aspirin and iron supplements a couple weeks before the test. The test is done using a local anesthetic for your throat so you cannot feel the tube going down your throat. You will also receive pain medication and a sedative through an IV. The doctor slides the tube down your esophagus and looks at your esophagus, stomach, and duodenum, or upper portion of your small intestine.
The procedure itself takes less than an hour. You should be allowed to go home 1 to 2 hours after your procedure. You will need a ride home, since you cannot drive after being on sedated, and you may not be able to operate machinery for another 12 or more hours. You can eat and drink after your throat is no longer numb.
