What is Colonoscopy?
Colonoscopy is an endoscopic procedure used to examine the inner lining of the large intestine (colon) and rectum. During the procedure, doctors insert a thin, flexible tube (colonoscope) through the anus. This tube has a camera and light source at the end, so doctors can see the inner surface of the intestine in detail. Colonoscopy is used to diagnose polyps, colitis, cancer, and other abnormalities. It can also be used to take biopsies and perform some minor surgical procedures. The procedure is usually painless and patients are often kept under sedation. Colonoscopy is also a recommended method for colon cancer screening.
Uses of Colonoscopy
Colonoscopy is used to diagnose intestinal bleeding, chronic diarrhea, a family history of colon cancer, and other digestive disorders. It is also recommended for routine colon cancer screening.
How is a colonoscopy performed?
During colonoscopy, patients are usually given light sedation. The endoscope is carefully advanced through the anus and the camera views the inner surface of the intestine. If necessary, the doctor may take a biopsy or remove polyps.
Risks and Side Effects of Colonoscopy
Colonoscopy is generally a safe procedure, but in rare cases it may involve risks such as bleeding, infection, or perforation of the intestinal wall. Slight gas and bloating may be felt after the procedure.
Preparation for Colonoscopy
Preparation for a colonoscopy usually involves fasting for a period of time before the procedure and a complete cleansing of the intestines. The doctor will give the patient special preparation instructions and the use of laxatives will usually be required.
Recovery Process After Colonoscopy
After the procedure, patients usually rest for a while and are kept under observation until the effects of sedation wear off. Most people can return to normal activities on the same day.
