Have you ever heard of a medical test called `(Flexible Sigmoidoscopy)`? Maybe you're looking into it because your doctor told you to do it. Or maybe you're just curious about it. Whatever the reason, don't be afraid . Today, we're going to talk about this test called `(Flexible Sigmoidoscopy)`, which is a method of examining the lower part of your colon, in a simple way that you can understand.
What is ``Flexible Sigmoidoscopy''? It's very simple!
Simply put, a ``Flexible Sigmoidoscopy`` is a test that looks inside the lower part of your large intestine . Think of it like a small, flexible tube. This tube has a small camera attached to one end. We call these types of instruments an ``Endoscope.`` This is a specially designed ``Sigmoidoscope.`` It is inserted through your ``Anus`` and through your ``Rectum`` to examine about the lower third of your ``Colon``.
There are four main parts of your large intestine. The last part is what we call the `(Sigmoid Colon)`. So that's why this test is called `(Sigmoidoscopy)`. But, this flexible tube `(Flexible Sigmoidoscope)` actually goes a little further, which is called the `(Descending Colon)`. This `(Descending Colon)` is where it comes down from the left side of your abdomen and connects to the `(Sigmoid Colon)`. Then it connects to the `(Rectum)`. Got it?
Why do we need this ``Flexible Sigmoidoscopy'' test?
Doctors use this ``Flexible Sigmoidoscopy`` test to check for signs of disease in the lower part of your colon . The clear images taken by the camera appear on a ``screen``, so the doctor can see what is happening inside the colon.
The most important thing is that during this test, if there is a suspicious area, a small piece of tissue can be taken from there and sent to the laboratory (`(Biopsy)`) . Sometimes, if there are small problems, it is possible to treat them through this `(Endoscope)` itself.
What can this test find? What does it identify?
If you have the following symptoms, a doctor may suggest this test:
- Bleeding from the rectum or blood in the stool.
- A change in the nature of your stools or bowel habits (e.g., persistent diarrhea or constipation).
- Persistent pain in the lower abdomen or pelvic area .
- Being thin for no reason .
Or, if there is something that needs to be investigated further based on the results of another test you have had (e.g., blood test, stool test, `(imaging test)`), this `(Flexible Sigmoidoscopy)` is also used for that.
Here are some things that can be found in this test:
- Inflammatory conditions of the lining of the colon (`(Colitis)` or `(Proctitis)`).
- Small, infected pouches in the lining of the colon (`(Diverticulitis)`).
- Narrowing of the intestine due to scar tissue (`(Stricture)` or `(Stenosis)`).
- Ulcers (sores) in the colon or rectum.
- Gastrointestinal bleeding.
- Colorectal polyps are growths that form in the colon and rectum. Some of these can be benign (non-cancerous) and some can be cancerous (cancerous).
Some people also have this ``Flexible Sigmoidoscopy'' performed as a screening test for colorectal cancer, along with other tests.
Can this detect colorectal cancer?
Yes, a flexible sigmoidoscopy can find cancer in the lower part of your colon or rectum. If it does, your doctor will need to examine your entire colon . This is called a colonoscopy. Because a flexible sigmoidoscopy does not examine the entire colon, it is not the best screening tool for colon cancer. But for some people, it is a good initial test.
Is a `(Sigmoidoscopy)` or a `(Colonoscopy)` better? What's the difference?
Now you may be wondering, "Why not just have a colonoscopy instead of a sigmoidoscopy?" That said, if your symptoms or other test results suggest that the problem is only in the lower part of your colon, it may not be necessary to see the entire colon.
A `(Colonoscopy)` is a slightly more complex test than a `(Flexible Sigmoidoscopy)`. Some people may find it a little difficult to do. It requires special preparation. `(Flexible Sigmoidoscopy)` usually does not require as much preparation. Also, `(Colonoscopy)` may require anesthesia (`(Sedation)` or `(Anesthesia)`.
Some people choose to have a sigmoidoscopy as a screening test for colon cancer, instead of a colonoscopy. If you are not at high risk for colon cancer and have health conditions that make it difficult for you to have a colonoscopy, this is a good option. Instead of having a colonoscopy every 10 years, you can have a sigmoidoscopy every 5 or 10 years , along with a fecal occult blood test every year.
How do you prepare for this test? Is it a big deal?
Most doctors prefer that your bowel is relatively empty before a Flexible Sigmoidoscopy. This means that you will be asked to limit what you eat and drink the day before the test. You may also be given something to help you pass stool before the test. Not everyone needs a bowel prep like a colonoscopy. But in some cases, doctors may ask for it. They may say things like:
- Eat a limited diet or liquid diet for 24 hours before the test. A clear liquid diet is best because it doesn't leave anything in the intestines. However, some people eat a little.
- You may be asked to use an enema or suppository (medicines that are inserted into the rectum) to help you pass stool before the test. This should be used the night before the test or the morning of the test.
- In some cases, you may be asked to take a laxative the night before the test. This may come in the form of a pill or a powder that you mix with water and drink. Some laxatives are stronger than others.
- You may be asked to stop or change some of the medications you are taking the day before the test . Therefore, you should clearly tell your doctor about your health conditions and all the medications you are taking.
Remember, all of this is done to ensure that the test is accurate and to get clear results. Therefore, it is very important to follow these steps exactly as the doctor tells you.
Does a ``Flexible Sigmoidoscopy'' hurt? Do I need sedation?
Most people do not need sedation or anesthesia for a flexible sigmoidoscopy. However, if you are concerned about this, you can talk to your doctor about it. The test is usually not painful . However, as the sigmoidoscope is passed into the colon, carbon dioxide gas is injected into the colon to inflate it, so you may feel a little full or a little bloated . This will go away after a while.
What happens during the test?
When you arrive for the exam, you will be given a hospital gown to wear. The doctor will then position you on the exam table. There are two common positions used:
- Left lateral (Sims) position: You should lie on your left side with your knees bent towards your chest.
- Knee-chest position: You should kneel on the table and bend your torso forward, leaning towards your knees.
Then, the doctor will apply a lubricant to the end of the endoscope and his gloved finger. He will first insert a finger into your rectum and examine it (a digital rectal exam). Only then will the endoscope be inserted.
As he slowly inserts the endoscope, he inflates the colon with air. You can feel the air. When the sigmoidoscope is about 24 inches (60 centimeters) away, he slowly starts to pull it out again, taking a second look.
The images taken by the sigmoidoscope will appear on a screen. If you are not under anesthesia, your doctor may ask you to change your position a little so that he can see you better. If you feel uncomfortable, he may ask you to change the position of the sigmoidoscope.
If the doctor sees something suspicious, he or she may take a sample of tissue (a ``biopsy'') . Sometimes, they can find things like ``polyps'' that have a low chance of becoming cancer. They are usually removed as soon as they are seen. You won't feel them .
If you see any bleeding or an injury during the exam, you can treat it through the sigmoidoscope. He or she may use an electrocautery tool to seal the injury or inject medication into it.
How long does this ``Flexible Sigmoidoscopy'' test take?
It usually takes about 15 minutes . If the doctor needs to remove things like polyps or treat an injury, it can take a little longer. If he sends tissue samples to the lab, it can take a few days for the results to come back.
What happens after the test?
After the examination, the doctor will tell you what he saw and what to do next. If a biopsy was taken, the results will take a few days to come back, so you will be informed about that later. You can continue your work and eat normally .
Are there any risks or side effects from this test?
There is a very small risk of injury or bleeding to your colon from a sigmoidoscopy. It is normal to have some bleeding from the rectum after the procedure, but it should not last more than a day. You may also experience some stomach pain from the air that was inserted until it passes. Some people may also experience diarrhea after the procedure. These are all temporary side effects . Walking around after the procedure can help to reduce these symptoms quickly.
However, if you experience excessive bleeding, severe stomach pain, or fever after the test, you should tell a doctor immediately.
What is the difference between `(Flexible Sigmoidoscopy)` and `(Rigid Sigmoidoscopy)`?
A `(Rigid Sigmoidoscopy)` does not use a flexible tube (`(Endoscope)`), but a thick, rigid tube. It is longer, shorter than a flexible tube, about 25 centimeters long. A `(Rigid Sigmoidoscopy)` is also called a `(Proctoscopy)`, and the instrument is also called a `(Proctoscope)`. The word `(Procto)` refers to your rectum `(Rectum).` Although this tube goes all the way to the `(Sigmoid Colon)`, it is mostly used to look for symptoms related to the rectum `(Rectum)` and the anus `(Anus)`.
Finally, remember this ! (Take-Home Message)
Flexible Sigmoidoscopy is a quick, safe, and effective way for doctors to diagnose and treat conditions in the lower part of your colon . It doesn't go as deep into your body as a colonoscopy, so it doesn't take as long or require as much preparation. It can be done with or without anesthesia. Most people tolerate it well without medication, even when tissue is removed. Your doctor may be able to diagnose and treat your problem with just one test .
So, if your doctor tells you to do this test, don't be unnecessarily afraid of it. Talk to your doctor about any questions or concerns you may have. Taking care of your health is the most important thing!
