EndoscopyWhat is an Endoscopy?

An upper gastrointestinal (UGI) endoscopy is a procedure that allows your doctor to look at the interior lining of your esophagus, your stomach, and the first part of your duodenum (small intestine) through a thin, flexible viewing instrument called an endoscope. The tip of the endoscope is inserted through your mouth and then gently moved down your throat into the esophagus, stomach, and duodenum (upper gastrointestinal tract).

Since the entire upper gastrointestinal (GI) tract can be examined during this test, the procedure is sometimes called esophagogastroduodenoscopy (EGD).

Using the endoscope, your doctor can look for ulcers, inflammation, tumors, infection, or bleeding. Tissue samples can be collected by biopsy, polyps can be removed, and bleeding can be treated through the endoscope. Endoscopy can reveal problems that do not show up on X-ray tests, and it can sometimes eliminate the need for exploratory surgery.


Bronchoscopy is a procedure that allows your doctor to look at your airway through a thin viewing instrument called a bronchoscope. During a bronchoscopy, your doctor will examine your throat, larynx, trachea and lower airways.

Colonoscopy is an outpatient procedure in which the large bowel (colon and rectum) is examined. Your doctor may perform the procedure to diagnose and treat, when possible, certain diseases of the lower gastrointestinal (GI) tract, which includes the rectum and colon.

Upper endoscopy, also called esophagogastroduodenoscopy, or EGD, uses a thin scope with a light and camera at its tip to look inside of the upper digestive tract – the esophagus, stomach, and first part of the small intestine, called the duodenum.

Endoscopic retrograde cholangiopancreatogram (ERCP) is a test that combines the use of a flexible, lighted scope (endoscope) with X-ray pictures to examine the tubes that drain the liver, gallbladder and pancreas.


Before You Arrive:

  • Do not eat or drink anything for 6 to 8 hours before the test. An empty stomach helps your doctor see your stomach clearly during the test.
  • Arrange for someone to transport you, since you will receive sedation and be unable to drive until the next day.
  • Check with your physician about taking your vitamins, diabetic medications, insulin, Coumadin, or aspirin products.
  • Depending on the type of test you are receiving you may expect to be here for 2-3 hours.
  • Remove all pierced body jewelry and wear comfortable clothes.
  • For your convenience, please call 455.5107 or 455.5109 to pre-register for your Endoscopic procedure.

Once You Are Here:

  • A small IV will be inserted to provide a site to inject medications for most procedures.

  • The physician will visit with you before and after your exam.
  • The results of your test will be discussed with you after your procedure.
