An upper endoscopy is a procedure to look at the lining of the upper digestive tract. The upper digestive tract includes the esophagus (food pipe), the stomach, and the duodenum (the first part of the small intestine). A long, thin, flexible tube with a tiny camera inside is passed into your mouth, then down your throat and stomach.
A thin tube with a camera and light on the end into your mouth and down into your esophagus, stomach, and duodenum. The doctor will look for irritation, bleeding, ulcers, or growth. A sample from the lining of your digestive tract may be taken. Treatment of any problem found will be done, including stopping a bleed, removing a growth, or widening areas of the narrowed esophagus.
You will be provided with instructions from your doctor about what to do after an upper endoscopy. You can go home within a few hours after the sedation wears off. In case you receive sedation, you should avoid driving, drinking alcohol, or operating heavy machinery for 24 hrs.
