Flexible sigmoidoscopy is a screening examination of the lower colon and rectum. It is very helpful in the diagnosis of many disorders, such as cancer of the colon and rectum, polyps (small benign growths which can become cancerous as they grow large), various kinds of inflammation which can cause bleeding, diarrhea, and similar problems. The American Cancer Society recommends that everyone over the age of 40 to 50 have this simple screening test every three to five years. The purpose is to detect polyps which might become cancerous. If polyps are identified, before they have turned into cancer, the polyps can be removed and the cancer prevented.

The flexible sigmoidoscope is a new instrument which allows the examination of the lower one-third of the large intestine, also called the colon. The instrument itself is about the diameter of a little finger, and is 60 centimeters (24 inches) long. Inside are light fibers which both transmit light into the colon, as well as allow the physician to look through a lens system which bends with the instrument. And, of course, the instrument is flexible, so that it can go around corners and folds in the intestine.

During the examination, the patient lies comfortably on his or her side, while the physician gently passes the instrument through the anus and rectum, then up into the lower colon. It is necessary for the doctor to introduce a small amount of air into the colon to expand it, so that all portions of the lining can be seen well. Apart from an occasional mild cramp and the sensation of having to pass this air, the exam is generally not uncomfortable, and takes only a few minutes. No medication is necessary during the procedure.

If the doctor sees something which needs further study, sometimes he will take a biopsy, a tiny piece of tissue to be studied under a microscope, to help in the diagnosis of certain conditions. If a biopsy is taken, the patient experiences no pain whatever, since the colon and rectum do not have nerves which are sensitive to pain.

Only minimal preparation is needed for this examination: one needs to take two Fleet enemas, available in any drug store, a couple of hours before the examination. These enemas each contain only 4 ounces of fluid, so are not difficult to use. The easiest way to accomplish this is to lie on one's side with the knees drawn up, insert the prelubricated tip of one of the enemas through the anus into the rectum, and squeeze the flexible bottle until all the fluid has gone into the rectum. Then get up, go to the bathroom and evacuate the enema and bowel contents. Repeat this once more, a few minutes later, and then come to the office for your appointment

Following the procedure, there are no restrictions on driving, diet or activity; most people return to normal activities as soon as they leave the office.
