What is Lower GI Endoscopy?

It is a special exam of your lower gastrointestinal (GI) tract. If you had an abnormal x-ray or symptoms of a lower GI problem, this procedure may be done to get a better look. It can also help treat certain lower GI problems. During the endoscopy, a long, narrow, flexible tube called an endoscope is used. This instrument contains a strong light and a video camera. Your GI tract can then be viewed on a video screen.

THE PROCEDURE

The Doctor and a nurse perform the procedure. Colonoscopy can take 30 minutes or longer. Sigmoidoscopy often takes less then 15 minutes.

During the Procedure

	You lie on the table on your left side.
	For colonoscopy, you are given sedating (relaxing) medication through an IV line. Sigmoidoscopy usually doesn’t require sedation.
	The endoscope is inserted into your rectum. You may feel pressure and cramping. If you feel pain, tell your doctor or nurse. You may receive more sedation or some pain medication.
	The endoscope carries images of your colon to a video screen. Prints of the image may be taken as a record of your exam.
	When the procedure is done, you rest for a time. If you have been sedated you must have an adult drive you home.
