Technology: Today we look into non-invasive colonoscopy

Posted by Xanit Internacional Xanit Internacional | Posted in Gastroenterology | Posted on 21-06-2019


Colonoscopy is one of the most common tests performed within the Gastroenterology Department. Its main goal is to explore for polyps or cancer in the large intestine. Polyps are benign growths that arise in the inner lining of the intestine. A small part of the polyps can grow and then become cancer.

To learn more about this test, today we want to explain exactly what a virtual colonoscopy consists of.…


What is virtual colonoscopy?

This virtual colonoscopy uses special X-ray equipment to examine the large intestine to identify cancer and growths called polyps.


What do we diagnose with colonoscopy?

It is used to explore for polyps or cancer in the large intestine in order to find such growths at an early stage so that they can be removed before cancer has the chance to develop.

People who are at increased risk for this disease or have a family history of colon cancer may begin screening at age 40 or younger and may undergo screening at shorter intervals (for example, having a colonoscopy every five years). Risk factors associated with the disease include a history of polyps or a family history of colon cancer.


How is it carried out?

During the examination, a small flexible tube is inserted into the rectum for a short distance so that it can be inflated with gas while CT images of the colon and rectum are taken.


What benefits does it have?

This minimally invasive test provides 2-D and 3-D images that can clearly describe numerous polyps and other lesions, as it provides more detailed images, also reaching the full length of the colon.

This technique significantly reduces the risk of colon perforation that can occur with conventional colonoscopy, becoming an excellent alternative for patients with clinical factors that increase the risk of complications from colonoscopy.

Elderly patients, especially those who are weak or sick, will tolerate CT colonography better than a conventional colonoscopy and it may also be useful when colonoscopy cannot be performed because the intestine is blocked or reduced for some reason.

This technique can detect abnormalities outside the colon, including malignant conditions in their early stages in other organs and potentially dangerous conditions.

Non-invasive colonoscopy is well tolerated as there is no need for sedatives or painkillers and there are no traces of radiation left in the patient’s body and there are usually no immediate side effects.
