An upper gastrointestinal (or GI) endoscopy is a test that allows your doctor to look at the inside of your esophagus, stomach, and the first part of your small intestine, called the duodenum. The esophagus is the tube that carries food to your stomach. The doctor uses a thin, lighted tube that bends. It is called an endoscope, or scope.
The doctor puts the tip of the scope in your mouth and gently moves it down your throat. The scope is a flexible video camera. The doctor looks at a monitor (like a TV set or a computer screen) as he or she moves the scope. A doctor may do this procedure to look for ulcers, tumours, infection, or bleeding. It also can be used to look for signs of acid backing up into your esophagus. This is called gastroesophageal reflux disease, or GERD. The doctor can use the scope to take a sample of tissue for study (a biopsy). The doctor also can use the scope to take out growths or stop bleeding.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.
