Video Colonoscopy: What is it? Indications, Preparation for the Exam, Recommendations and Contraindications

At present, the prevention and diagnosis of the pathology of the large intestine have been simplified, thanks to the modern endoscopic devices that exist on the market.

A colonoscopy video is nothing more than the most precise procedure and one of the study methods that allows the doctor to observe the complete images and identify the inflammations, ulcers, or tumors present in the area.

In contrast to conventional endoscopy or colonoscopy, the colonoscope video is equipped with a chip that has a powerful camera at 1.25 million pixels.

In this way, it allows to see the intestinal wall extensively and ensures the registration of photographs and videos in HD quality.

The diagnoses are made using filters in front of the white light source of conventional lighting.

The colonoscopy video also allows the proctologist to obtain biological material for analysis and eliminate small polyps.

Indications for a colonoscopy video

  • The colonoscopy video is performed when certain conditions such as:
  • The disease of corn can affect the colon.

Currently, the colonoscopy video is the best method of colon examination. However, there are alternative methods, such as barium enema, 3D virtual endoscopy capsules, colonoscopy with scanners, and computed tomography.

Although these studies are less accurate, they are often used to clarify the diagnosis.

The barium enema is an affordable alternative diagnostic treatment in cases where any type of colonoscopy is impossible to perform due to contraindications for each patient’s conditions.

The procedure of the colonoscopy video is very informative. This video allows you to observe the status of the areas studied in great detail due to the increase in the monitor screen.
