What is an upper GI endoscopy?
An upper GI endoscopy or EGD (esophagogastroduodenoscopy) is a procedure to diagnose and treat problems in your upper GI (gastrointestinal) tract.The upper GI tract includes your food pipe (esophagus), stomach, and the first part of your small intestine (the duodenum).
This procedure is done using a long, flexible tube called an endoscope. The tube has a tiny light and video camera on one end. The tube is put into your mouth and throat. Then it is slowly pushed through your esophagus and stomach, and into your duodenum. Video images from the tube are seen on a monitor.
Small tools may also be inserted into the endoscope. These tools can be used to:
Take tissue samples for a biopsy
Remove things such as food that may be stuck in the upper GI tract
Inject air or fluid
Stop bleeding
Do procedures such as endoscopic surgery, laser therapy, or open (dilate) a narrowed area
It is often used to find the cause of unexplained symptoms such as:
Trouble swallowing (dysphagia)
Unexplained weight loss
Upper belly pain or chest pain that is not heart-related
Continuous vomiting for an unknown reason (intractable vomiting)
Bleeding in the upper GI tract
An upper GI endoscopy can be used to identify disorders or problems such as:
GERD (gastroesophageal reflux disease)
Narrowing (strictures) or blockages
Larger than normal veins in your esophagus (esophageal varices)
Redness and swelling (inflammation) and sores (ulcers)
Tumors, either cancerous (malignant) or not cancerous (benign)
The stomach moving upward, either into or next to your esophagus (hiatal hernia)
Damage caused by swallowing very harmful (caustic) substances, such as household detergents and chemicals
Celiac disease
Crohn's disease of the upper GI tract
Infections of the upper GI tract
An upper GI endoscopy can also treat problems in the upper GI tract. The procedure can be used to:
Control bleeding
Remove tumors or growths (polyps)
Open (dilate) narrowed areas
Remove things that may be stuck
Perform laser therapy
Insert a tube used for tube feeding (a percutaneous gastrostomy tube) into the stomach
Band abnormal veins in your esophagus (esophageal varices)
