Colonoscopy (videocolonoscopy) is an overview of all the parts of the large intestine taking into account the inversion examinations with 180° rotation. Thus, an optical device visualizes the intestinal mucous membrane at the exit, because it is the place where polyps and other neoformations are located.
Colonoscopy is the gold standard of screening diagnostics of colorectal cancer.
Colonoscopy allows to visually assess the condition of large intestine mucous membrane, to find inflammatory changes and neoformations timely. The method is informative in case of suspected oncological diseases.
Besides, the modern colonoscopy includes the check of the end section of large intestine. Neoformations (polyps and oncology at early stages) can be seen during a diagnostic procedure and removed immediately.
Specialists advise to undergo colonoscopy starting from 45 years of age, and even earlier in the cases of oncological alertness associated with the hereditary background.
It is also not recommended to perform colonoscopy just after a surgery and for the patients with revealed acute inflammatory and necrotic processes in anal and rectum areas.
The procedure is rather unpleasant, sometimes painful, and it is recommended to perform it under general anesthesia (medication sleep) (if there are no contraindications). That is why it is necessary to do clinical blood analysis, electrocardiography and get a consultation by anaesthesiologist as a preparation. The procedure can also be performed with no anesthesia at the patient’s request.
