Colonoscopy
Colonoscopy is the examination of the entire large intestine and, if necessary, the final part of the small intestine using a soft, flexible instrument equipped with a camera. For the procedure to be performed effectively, bowel cleansing with laxatives is required the day before.
With current technology, colonoscopy is the best method both for diagnosing and treating diseases of the colon. It is widely known that colon cancers often originate from small, benign growths called polyps. Over time, these polyps can become malignant, developing into cancer. Colonoscopy allows for the removal of these polyps, preventing colon cancer from developing. It can also diagnose inflammatory bowel disease, stop intestinal bleeding, widen strictures, and treat hemorrhoids and anal fissures.
At our clinic, colonoscopies are performed under sedation in a safe and clean environment, ensuring the patient feels no pain or discomfort during the procedure. The patient can return to their daily activities afterward. In skilled hands, colonoscopy is a low-risk procedure.
Pre-Procedure Assessment
Patients are evaluated for any accompanying illnesses, and their medications are adjusted accordingly (e.g., antibiotics for heart valve replacements, blood thinners, or anti-diabetics). Bowel preparation is tailored to the patient's known medical conditions and physical structure.
Since the procedure is performed under deep sedation, general anesthesia is usually unnecessary unless there are special circumstances. Without sedation, the patient may feel pain due to the air introduced into the colon for visualization, causing gas discomfort. However, with sedation and pain relief, the patient experiences no discomfort and does not remember the procedure.
Who Should Have a Colonoscopy and When?
If you are over 45 years old, even without symptoms, it is recommended to undergo colonoscopy every 5 years for the early detection and prevention of colon cancer. Removing polyps through colonoscopy can completely prevent the development of colon cancer.
Colonoscopy is recommended for individuals who:
Have rectal bleeding (often mistaken for hemorrhoids or fissures)
Have positive fecal occult blood test results
Have a family history of colon cancer or polyps (first-degree relatives)
Experience changes in bowel habits within the last six months
Have chronic or unexplained diarrhea
Suffer from bloating, gas, or constipation
Experience unexplained weight loss
Have persistent, unexplained abdominal pain
Post-menopausal women diagnosed with iron-deficiency anemia
Men with iron-deficiency anemia in any case
Have inflammatory bowel diseases such as ulcerative colitis, for follow-up purposes
