Colonoscopy, which is performed to examine the internal structure of the large intestine and rectum, is important for colon cancer screening, especially for individuals aged 50 and over. Colonoscopy is used to diagnose bowel diseases or check for tumors and, in some cases, to take biopsies. The procedure is performed with a colonoscope, a thin flexible tube inserted through the rectum. There is a camera at the tip of the colonoscope. In this way, the doctor can image the inside of the intestines and detect abnormalities such as polyps, tumors or inflammation.
What is a colonoscopy?
Colonoscopy is an important diagnostic tool used to examine the large intestine and rectum. It is usually performed through a colonoscope, which is a thin tube. A colonoscope is a device with a camera at its tip and is administered under anesthesia or with local anesthesia. Colonoscopy is done to diagnose bowel diseases, check for polyps or tumors, and in some cases, take a biopsy. A special diet and medication are required to cleanse the intestines before the procedure.
How is a colonoscopy done?
Colonoscopy, which is performed to examine the internal structure of the intestines, begins with cleaning the intestines. Patients follow a specific diet and laxatives before the procedure. On the day of the procedure, the patient is usually prepared by receiving light sedation. The doctor carefully inserts the colonoscope through the rectum and advances it along the intestine, while taking images of the intestines thanks to the camera. Special instruments are also used to take a biopsy if abnormal findings are detected.
How long does a colonoscopy take?
The colonoscopy procedure is usually completed within 30 minutes to 1 hour. However, when the preparation process and the patient’s observation time are added, it may take several hours. The duration of the procedure may vary depending on the doctor’s findings and the necessary biopsy. After the procedure, patients usually need to be observed for a few hours. This period is important for the effect of sedation to wear off and for monitoring possible side effects. Considering all these factors, it is important to plan carefully when making a colonoscopy appointment.
