It is a method of imaging the entire large intestine and the last 10-15 cm of the small intestines by entering through the anus through a thin and flexible tube. Before the procedure, the intestines must be cleaned with oral medications. In rectosigmoidoscopy, the part of the large intestine close to the anus (the last 20-25 cm.) is examined.
Colonoscopy is the most reliable method in the diagnosis of large intestine diseases, and polyps and similar precancerous lesions require surgery. It protects patients from cancer by allowing it to be taken without any delay.
Colonoscopy is recommended for people over the age of 40 with rectal bleeding or hidden blood in the stool, menopausal women with anemia, and anyone over the age of 50 to investigate colon cancer and colon polyp.
>Those who have first-degree relatives with colon cancer should have a colonoscopy starting 10 years before the age at which their relative first developed it. The majority of colon cancers develop on benign tumors called polyps. Colonoscopy, performed for screening purposes, enables polyps to be found and removed at a stage before cancer develops. In this way, colonoscopy saves patients from both cancer and surgery.
In patients with polyps removed from the large intestine, follow-up colonoscopies must be performed every 1 to 3 years, depending on the type of polyp.
