: Endoscopic Procedure, Gastrointestinal Tract

: What Is an Endoscopic Procedure?

: An endoscopic procedure uses a thin, flexible tube called an endoscope that has a light and a small camera at the tip. The doctor gently guides it into your body to view the lining of the gastrointestinal tract on a screen. Upper endoscopy examines the food pipe, stomach, and first part of the small intestine, while colonoscopy examines the lower bowel.

: Why Is It Done?

: Endoscopy may be recommended to investigate symptoms such as ongoing heartburn, stomach pain, nausea, vomiting, trouble swallowing, or changes in bowel habits. It can also help find the cause of bleeding, check for ulcers or inflammation, screen for certain growths, and monitor a known condition.

: How to Prepare

: Preparation depends on the type of procedure. For upper endoscopy, you are usually asked not to eat or drink for several hours beforehand. For colonoscopy, you typically follow a special diet and take a bowel-cleaning preparation. Tell your care team about all medicines, allergies, and health conditions so they can give you instructions specific to you.

: What to Expect

: You may be given sedation to help you relax, and the procedure usually takes a short time. The doctor may take small tissue samples called biopsies, which are painless. Afterward you may rest briefly and are usually monitored before going home. Someone may need to drive you home if sedation is used.
