What is a colorectal adenoma?
Colorectal adenoma is abnormal glandular tissue growth in the gastrointestinal tract. These growth can be diagnosed with colonoscopy, air contrast barium enema or computer tomography (CT). They can be classified according to their appearance with the naked eye and their microscopic characteristics. Colorectal adenomas are treated by their removal because there is a risk that they can develop on cancer if they stay in the body.
irregular growth of normal glands in the gastrointestinal tract leads to colorectal adenoma. In the gastrointestinal tract, the colorectal part is a tube -shaped structure through which partially bumped food and waste products move. Part of the gastrointestinal system that contacts the digestive food is made of epithelial tissue. Under this epithelial tissue lies a number of glands that produce substances important for the digestion process. The abnormal proliferation of these glandular structures is what makes adenoma.
diagnosis adenOMU is usually done by performing colonoscopy. In this procedure, doctors put a probe containing a camera through the rectum to visualize the inner surface of the large intestine and rectum. Any tissue protruding abnormally is removed during the procedure. It is then sent to a pathologist for microscopic analysis. Colorectal adenomas can also be detected by other imaging techniques such as CT scan or air-circular enema, but coloscopy offers another advantage that it is able to immediately remove adenoma.
Removal is a correct treatment of colorectal adenoma. The reason why removal is required is that approximately five percent of colorectal adenomas evolve into colorectal cancer. If colonoscopy is diagnosed, the adenoma is removed as soon as it is visible. Patients who are diagnosed with other imaging methods require subsequent colonoscopy to remove TON Adenoma.After removal, patients are monitored by repeated colonoscopy performed at least every five years.
Three types of adenomas can be seen during colonoscopy. They are named on the basis of their structure and appearance. Substained adenomas are structures with large, wide foundations. Like USessile Adenomas, flat adenomas also have large bases associated with the inner wall of the gastrointestinal tract, but these growth usually has a diameter at least twice as long as height. Pedunculated adenomas are the third type and are mushrooms in the shape of a narrow stem connecting the inner intestinal surface with growth.
In addition to being classified due to the naked eye, colorectal adenoma can be categorized according to its microscopic features. This determination is often performed by a pathologist examining adenoma after removal. One classification is Vilus Adenom; In this subtype, the abnormal glands forming adenoma an extended pattern. Tubular adenomas, other subtypes, have glands with a branched structure. WhoThe binoculars of two types of microscopic structures are described with the term tubulovillou.
