Flexible Sigmoidoscopy

Your caregiver has ordered a flexible sigmoidoscopy. This is an exam to evaluate your lower colon. In this exam your colon is cleansed and a short fiber optic tube is inserted through your rectum and into your colon. The fiber optic scope (endoscope) is a short bundle of enclosed flexible small glass fibers. It transmits light to the area examined and images from that area to your caregiver. You do not have to worry about glass breakage in the endoscope. Discomfort is usually minimal. Sedatives and pain medications are generally not required. This exam helps to detect tumors (lumps), polyps, inflammation (swelling and soreness), and areas of bleeding. It may also be used to take biopsies. These are small pieces of tissue taken to examine under a microscope.

LET YOUR CAREGIVER KNOW ABOUT:

  • Allergies.

  • Medications taken including herbs, eye drops, over the counter medications, and creams.

  • Use of steroids (by mouth or creams).

  • Previous problems with anesthetics or novocaine

  • Possibility of pregnancy, if this applies.

  • History of blood clots (thrombophlebitis).

  • History of bleeding or blood problems.

  • Previous surgery.

  • Other health problems.

BEFORE THE PROCEDURE

Eat normally the night before the exam. Your caregiver may order a mild enema or laxative the night before. No eating or drinking should occur after midnight until the procedure is completed. A rectal suppository or enemas may be given in the morning prior to your procedure. You will be brought to the examination area in a hospital gown.

You should be present 60 minutes prior to your procedure or as directed.

AFTER THE PROCEDURE

  • There is sometimes a little blood passed with the first bowel movement. Do not be concerned. Because air is often used during the exam, it is not unusual to pass gas and experience abdominal (belly) cramping. Walking or a warm pack on your abdomen may help with this. Do not sleep with a heating pad as burns can occur.

  • You may resume all normal eating and activities.

  • Only take over-the-counter or prescription medicines for pain, discomfort, or fever as directed by your caregiver. Do not use aspirin or blood thinners if a biopsy (tissue sample) was taken. Consult your caregiver for medication usage if biopsies were taken.

  • Call for your results as instructed by your caregiver. Remember, it is your responsibility to obtain the results of your biopsy. Do not assume everything is fine because you do not hear from your caregiver.

SEEK IMMEDIATE MEDICAL CARE IF:

  • An oral temperature above 102° F (38.9° C) develops.

  • You pass large blood clots or fill a toilet with blood following the procedure. This may also occur 10 to 14 days following the procedure. It is more likely if a biopsy was taken.

  • You develop abdominal pain not relieved with medication or that is getting worse rather than better.
