Sigmoidoscopy is a procedure that you might need to undergo if you have symptoms of colorectal cancer or inflammation and ulceration in your rectum and lower (sigmoid) colon.
These worrisome symptoms include:
The Digestive Disease Consultants of Orange County team also uses flexible sigmoidoscopy to screen for polyps in your rectum and lower colon. Screening detects colorectal cancer at an early stage when there's a much better chance of treating it successfully.
Your provider at Digestive Disease Consultants of Orange County can advise you whether you need to undergo a sigmoidoscopy for screening purposes. The indicators for screening below the age of 50 include:
If you're at risk, your provider might recommend a colonoscopy, which is a similar procedure to a sigmoidoscopy. The difference is that with a colonoscopy, your provider can see the entire length of your large intestine rather than just the lower section.
Before your sigmoidoscopy, you need to clean out your bowel by following the instructions your provider at Digestive Disease Consultants of Orange County gives you. This typically involves drinking large quantities of laxative powder dissolved in water the day before your procedure.
The preparation does cause diarrhea, so you should stay near a convenient toilet. Passing large volumes of liquid stool can be uncomfortable, but if your bowel isn't totally clean and empty, your provider won't get a clear image during the procedure.
You also need to follow the instructions regarding what it's safe to eat and drink before your sigmoidoscopy.
To perform a sigmoidoscopy, your provider at Digestive Disease Consultants of Orange County passes a slender, flexible instrument (a sigmoidoscope) into your rectum through your anus.
The sigmoidoscope has a light and a tiny camera on it. As it goes up your rectum and into your colon, the instrument pumps in air to expand the bowel and provide a clearer view. It relays the images of the lining of your rectum and lower colon to a screen in the treatment room.
A flexible sigmoidoscopy takes around 20 minutes to complete. The procedure shouldn't be painful, and most patients don't require anesthesia, but you might like to have a sedative. If your provider sees any areas of inflammation, they take a biopsy for laboratory analysis. They can also remove any polyps that they find.
Once your sigmoidoscopy is complete, you can eat and drink normally, although because of being sedated, you’ll need someone else to drive you home after the procedure.
