As the sigmoidoscope is slowly removed, the lining of the bowel is carefully examined. A channel in the scope allows for the passage of forceps for biopsies or other instruments for therapy. How The Test Will Feel There will be pressure when the scopes or fingers are introduced into your rectum. There will be a feeling of the need to defecate during the procedure. There may be some bloating or cramping from distention of the bowel by air or stretching by the sigmoidoscope.
Biopsies cause no discomfort.
After the test, you will expel the air that was introduced. How To Prepare For The Test You must sign an informed consent form. You will wear a hospital gown. On the morning of the procedure, eat a light breakfast and then use a cleansing enema about 1 hour before the sigmoidoscopy. 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.
