There are two types of colonoscopies: a virtual colonoscopy, which involves a CT scan, and a traditional colonoscopy, which involves using a small camera on a flexible colonoscope. Both have strengths and weaknesses that need to be understood. While it may not sound thrilling to anyone, it’s important to be familiar with colon health so as to make the process feel less frightening to you. Let’s take a look at these two methods in simple, friendly terms, step by step, so you will understand exactly what they are and how they differ.
What Is a Virtual Colonoscopy?
Using a CT scanner, a virtual colonoscopy is a minimally invasive imaging procedure that is used to provide detailed visualization of the colon and rectum. Does not need a camera to be inserted into the colon. In order to ensure that the doctor will be able to clearly visualize the intestinal lining, the bowel needs to be cleaned prior to the scan. Virtual colonoscopy may allow for the identification of growths, polyps, and other abnormalities that may need to be evaluated further.
What is a Traditional colonoscopy and how is it different from an Endoscopy?
Colonoscopy is a type of endoscopy that uses a flexible tube with a camera and light but examines different areas of the digestive tract. An endoscopy examines the upper digestive tract, while colposcopy is for the lower digestive tract. The standard colonoscopy involves a flexible, thin tube with a small camera that is inserted into the rectum to visually explore the colon and rectum. Careful guidance is used through the large bowel, and sedation is provided for the patient for comfort. Doctors can detect abnormal tissue, remove polyps or obtain biopsies for laboratory analysis, if needed, during the procedure.
Understanding the Two Colonoscopy Methods
What is a virtual colonoscopy? It is an X-ray test that makes detailed images of the colon that are not taken inside the body. In a traditional colonoscopy, however, a thin, flexible tube that is equipped with a camera is used to directly see the lining of the colon during the colonoscopy procedure. What disease can be detected by a colonoscopy?
- Crohn’s disease and ulcerative colitis
- Intestinal Bleeding
- Bowel Obstructions
- Strictures
What are the Primary benefits of getting a Virtual Colonoscopy?
Many are attracted to virtual colonoscopy because they do not have to insert the camera and undergo sedation like in a traditional colonoscopy. Virtual colonoscopy vs colonoscopy is often related to comfort, convenience and recovery time, with virtual colonoscopy being able to help patients resume their normal activities faster.
Benefits of Virtual Colonoscopy
- No sedation required – you can drive yourself home immediately after the scan.
- More rapid recovery—most people up and around the same day they are admitted to the hospital.
- No scope will ever be inserted into the body as in a traditional colonoscopy, but it is less invasive.
- Comprehensive three-dimensional imaging of the colon, which shows the whole length of the colon well.
- A faster appointment time than with the traditional format and longer recovery time.
- A more pleasant choice for those who are not at ease during the process of sedation
What are the risks or drawbacks to virtual colonoscopy?
Virtual colonoscopy is convenient, but there are some limitations. In rare cases, if something abnormal is detected during the scan, a regular colonoscopy might also be necessary afterward to further examine the area or obtain tissue for testing. This does not make virtual colonoscopy a substitute for the traditional colonoscopy.
Virtual Colonoscopy drawbacks.
- Is unable to remove polyps or obtain tissue samples at the time of the scan.
- May still need a follow-up “old-fashioned” colonoscopy if there is something abnormal discovered
- Less sensitive to finding very small growths than direct camera viewing
- Exposes to radiation as the scan uses CT imaging technology, but there is some exposure involved
- May not be insured the same way by all programs or carriers for a reason
- Must follow the same bowel preparation prior to the procedure as a conventional colonoscopy procedure
Which Colon Examination may be appropriate for you?
The right colon test is not for everyone. It can depend on your symptoms, your age, what screenings you need, your past health, and what your clinician recommends. In many cases, a standard colonoscopy lets the doctor look directly with clear video. It also allows polyp removal or tissue sampling during the visit. A virtual colonoscopy uses CT scans. For some people, it can be a lower impact option.
Sedation and Recovery
With a traditional colonoscopy, many patients get mild to moderate sedation. Some people feel drowsy, and they may still feel off afterward. Most people spend about one to two hours in recovery. You will also need a ride home. Virtual colonoscopy usually does not use sedation. Because of that, recovery is often quicker, and many patients can get back to everyday routines sooner. Your own situation and the details of the planned test still matter. Knowing this distinction will also help to explain why virtual colonoscopy is sometimes viewed as less radiative than other CT scans.
