Western Baptist Hospital offers patient information on what to expect during a sigmoidoscopy.

The Purpose of Sigmoidoscopy

After careful medical examination, your doctor may recommend that you have a flexible sigmoidoscopy. During this procedure, a lubricated, flexible scope is introduced into your rectum and passed through the lower part of your large intestine. This procedure allows the doctor to examine your rectum and sigmoid colon to identify any abnormalities. It takes about 15 minutes to perform.

About the Procedure

When you arrive for your scheduled sigmoidoscopy, you will be asked to sign a consent form authorizing the doctor to perform the procedure. Please let the doctor and GI nurse know if you are allergic to any medications. Bring a list of your current medications with you.

During this procedure, you will lie on your side. When the doctor inserts the lubricated scope into your rectum, he or she will examine the lower part of your colon. You may experience some gas, cramping or the feeling that your bowels have to move. Slow, deep breaths will help to ease this feeling. A tiny piece of tissue may be taken for microscopic examination.

After Your Sigmoidoscopy

After the procedure is completed, the doctor will discuss his findings with you, the nurse and your family members. You will also be given written instructions for home care upon your discharge.

Because you will receive sedation, it is very important that you arrange to have someone who can drive you home accompany you the day of the procedure. You must have a ride home or the procedure will not be done. Wait at least 24 hours after you have returned home to drive or operate any equipment, drink any alcoholic beverages, take any sleeping pills or sign any important documents. It is also advisable that you go home and nap following the procedure. You may want to eat when you get home.
