Sigmoidoscopy
Back to Gastroenterology and Endoscopy /

Concept

Flexible sigmoidoscopy is a procedure that enables physicians to examine the lumen the large intestine from the rectum through the “sigmoid� or descending colon.

 

When is it needed?

It is mostly used for the investigation of diarrhea, abnormal pain or constipation causes. Also, it is used for detecting early signs of cancer in the rectum and descending colon. Using this procedure, physician could detect inflammation, bleeding, abnormal growths and ulcers.

How should you prepare yourself for the procedure?

  • The colon and rectum should be completely empty
  • You will be given a liquid diet for 12 to 14 hours beforehand (diet will include fat-free bouillon, gelatin, fresh juices, water, plain coffee and plain tea or diet soda).
  • Before the procedure, you will be given an enema (a liquid solution that cleans up the intestines)
  • In addition to the instructions given by your physician.

 

What to expect from this procedure?

  • This procedure takes 10 to 20 minutes
  • First, you should be lying on your left side, on the examining table. The physician will insert the sigmoidoscope (a short flexible lighted tube into the rectum and slowly guide it into the colon). This scope transmits an image of the inner part of the rectum, to be examined by the physician. Also, the scope blows air and inflates it for better view.
  • In case the physician detects any abnormalities such as polyps or inflamed tissue, he will take a sample using tiny tools and send it to the laboratory for investigation.
  • You may feel certain cramps pain in your lower abdomen, but it will be relieved after air leaves your colon
