Virtual Colonoscopy: A Non-Invasive Approach to Colon Health Screening

Colon cancer is one of the leading causes of death in the world. Unfortunately, we do not pay much attention to it as it has a high survival rate compared to lung and heart cancer. Nevertheless, it does not mean that we should not pay attention to colon health. The virtual colonoscopy procedure is one of the best ways to analyze colon health in case of any symptoms. Many people assume that colonoscopy is a painful procedure, and the fear of pain keeps them away from the diagnosis. However, virtual colonoscopy is less invasive than a traditional one. In this post, we will explain the benefits and procedure of virtual colonoscopy for colon health screening. 

What is a Virtual Colonoscopy?

Just like an angiogram scan has a virtual type, in the same way, there is a virtual colonoscopy. Virtual colonoscopy involves the examination of the large intestine and the rectum to detect any abnormalities within them. The scan uses CT or X-rays to create detailed images of the colon and rectum to identify any cancerous or non-cancerous polyps. It also focuses on the bowel movement. In addition, it not only identifies the cancer but other conditions as well, including bleeding, internal wounds, and bowel movement problems. Nevertheless, the process is less invasive and painless; thus, it is the preferred choice for many patients. 

What are the Benefits of Virtual Colonoscopy?

You do not have to take any sedation for this process; rather, it is a painless procedure. In addition to this, there are some other benefits as well that include the following: 

• It is less invasive and less uncomfortable than traditional colonoscopy.

• It does not take much time. The whole time is about 15 to 20 minutes. 

• There is less risk of wounds within the large intestine due to the scan. 

• This scan is a better option for those people who cannot go for colonoscopy more often. Further, it is an option for those people who have issues like bleeding and respiratory disorders. 

• Sometimes, it highlights those areas that regular colonoscopy does not reach. In that regard, it offers an in-depth view of the colon. 

Who Should Consider a Virtual Colonoscopy?

According to the American Cancer Society, most people go for a colonoscopy at the age of 50. However, to avoid the risk of cancer, you must go earlier, around the age of 45, if you have a family history of colon cancer. 

Apart from that, if you are facing any symptoms of colon cancer or are noticing any abnormalities in your digestive system, then you must consult with your doctor. 

What is the Virtual Colonoscopy Procedure?

The virtual colonoscopy procedure is simple. However, the process is detailed and includes the following steps: 

• Prior to the scan, you will have to be on a liquid diet for almost two to three days. The purpose is to clean the bowel to get the best results of the scan. Your doctor or the radiologist will guide you about this. 

• The scan takes less time, around 15 to 20 minutes, but you have to come earlier for preparation. 

• Before the scan, you will be given a liquid to drink that acts as a contrast dye to get a clear view of the colon.

• During the scan, a thin tube will be inserted into the rectum to inflate the colon with air. It helps in getting a better view of the colon. 

• You will lie on the table that will go inside the scanner while the scanner revolves around your body to take the images of the rectum and colon. 

What are the Risks of Virtual Colonoscopy

The virtual colonoscopy procedure is known for its benefits, but there are some risks as well, including the following: 

• The insertion of a small tube into the rectum to pump the colon carries a small risk of rupture. However, the risk is less than that of traditional colonoscopy.

• This process does not remove polyps. For that, a traditional colonoscopy will be needed.

Colonoscopy and its Types 

Colonoscopy and its types depend on the needs. The three basic types include the following: 

• One type is diagnostic colonoscopy, which includes the examination of the rectum and colon to detect abnormalities. It might be both a virtual or traditional colonoscopy.

• Preventive colonoscopy is a screening for cancer-based patients. 

• Virtual colonoscopy includes the use of CT technology to capture images of the colon and rectum.
