Polyps of the colon and their causes
By colon polyps Coloproctologists attracted the attention of the whole world,
as bowel cancer in most cases develops
from a benign polyp.
An important role in the development of colon polyps play:
- hereditary factors;
- chronic somatic diseases that contribute to "aging" of the epithelium of the colon mucosa;
- feeding habits;
In addition to hereditary factors, the wideningpolyps and malignant transformation promotes the use of a large number of animal and fatty foods, and constipation. Animal fats and proteins lead to the formation of carcinogenic substances in the intestine, breaking update mucosal cells. Constipation contribute to long-term effects of such substances.
In addition, each third of patients with polyps rectal bleeding is observed. Moreover, the larger the polyp, the more frequent the bleeding.
Villous tumors account for 15% of allBenign tumors of the colon, and most often located in the rectum (80%). The large size of these tumors, the propensity to ulceration and damage to predispose to rectal bleeding.
Problems polyps engaged gastroenterologist. Timely diagnosis and treatment of polyps prevents the development of colon cancer.
The main method of diagnosis of polyps colonoscopy -bowel inspection area up to one meter with a special endoscope introduced into the anus. This procedure shall be subject to every person older than 50 years. If in a family there are cases of colon cancer, it is necessary to perform a colonoscopy, regardless of age.
Before colonoscopy doctor may prescribe:
- fecal occult blood;
- irrigoscopy - X-ray examination of the intestine using a contrast agent administered with the help of an enema;
- sigmoidoscopy - a procedure similar to a colonoscopy, the bowel is examined only land up to 30 cm.
Timely removal of small, almost always asymptomatic colon polyps - the main measure of prevention of colon cancer.
Surgical treatment of colon polypsperformed using endoscopic equipment. In the anus introduced a flexible endoscope (an endoscope is carried out in such a colonoscopy), equipped with a loop electrode that captures and clamped leg of the polyp. Large polyps are removed in pieces. Removal of polyps are sent for histological examination, which allows you to determine if malignant transformation in a polyp or not under a microscope.
Endoscopic polypectomy well tolerated after surgery operation is restored on the next day.
After removal of large polyps (2cm) or multiple polyps (5 or more) and villous adenomas of any size necessary control endoscopy one year. If new polyps are found, a colonoscopy is repeated every three years.
Preventive removal of colon polyps is effective in prevention of colorectal cancer, and colon cancer warns at 99.55% of patients.
