Colonoscopy

What is a Colonoscopy?

A colonoscopy is a minimally invasive procedure used to examine the inner lining of the colon (large intestine) and rectum. It is performed by a gastroenterologist to detect abnormalities such as polyps, inflammation, or cancer.

Recommended for individuals over 50 or those with specific gastrointestinal symptoms or a family history of colorectal cancer, a colonoscopy is an important tool in the prevention and early detection of colorectal diseases.

How is a Colonoscopy Performed?

A colonoscopy is typically an outpatient procedure. Prior to the procedure, patients undergo a bowel preparation process that involves a special diet and laxatives to ensure the colon is clear.

• Sedation: Patients are usually given a sedative or anaesthesia to ensure comfort during the procedure.
• Insertion of the Colonoscope: A long, flexible tube equipped with a light and camera (colonoscope) is gently inserted into the rectum and guided through the colon.
• Examination: The camera transmits real-time images to a monitor, allowing the doctor to thoroughly inspect the colon lining.
• Biopsy or Polyp Removal: If abnormalities such as polyps or suspicious tissue are found, they can be removed or biopsied during the same procedure.
• Completion: The colonoscope is carefully withdrawn, and the entire process usually takes 30 to 60 minutes.

After the procedure, patients may experience mild bloating or cramping, but these symptoms typically resolve within a few hours.
