EGD (esophagogastroduodenoscopy)

How the Test is Performed:
You will be given a sedative and an analgesic . A local anesthetic will be sprayed into your mouth to suppress the need to cough or gag when the endoscope is inserted. A mouth guard will be inserted to protect your teeth and the endoscope. Dentures must be removed.

An IV may be inserted to administer medications during the procedure.

You are instructed to lie on your left side.

After the gag reflex has been suppressed by the anesthetic, the endoscope will be advanced through the esophagus to the stomach and duodenum . Air will be introduced through the endoscope to enhance viewing. The enteral mucosal surface is examined and biopsies can be obtained through the endoscope.

When the area has been viewed and any biopsies taken, the endoscope will be removed and you will be asked to cough to expel the extra air. Food and liquids are restricted until your cough reflex returns.

The test lasts about 30 to 60 minutes.

How to Prepare:
Fasting is required overnight (6 to 12 hours before the test). An informed consent form must be signed.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:



How it Feels:
The local anesthetic makes swallowing difficult. This wears off shortly after the procedure. The endoscope may stimulate some gagging in the back of the throat. There may be a sensation of gas and the movement of the scope can be felt in the abdomen. Biopsies cannot be felt.

Risks:
There is a small chance of perforation of the stomach, duodenum , or esophagus; or bleeding at the biopsy site.
A patient could have an adverse reaction to the anesthetic, medication, or tranquilizer. This could cause:

The overall risk is less than 1 out of 1,000 people.

Why this Test is Performed:
This test is helpful in determining:

  • the cause of upper GI (gastrointestinal) bleeding
  • the presence of ulcerations or inflammation
  • the cause of abdominal pain
  • the condition of the stomach and duodenum after an operation
  • the presence of tumors or other abnormalities of the upper GI tract
  • inflammation, narrowing, or tumors of the esophagus



Normal Values:
The esophagus, stomach, and duodenum should be smooth and normal color. There should be no bleeding , growths, ulcers or inflammation.

Abnormal Results:
An EGD may indicate:



Cost:
The estimated cost is $475 to $500 for the physician and about $590 to $650 for the hospital. The total cost is $1,065 to $1,150.
