What is Colonoscopy ?
Colonoscopy is a medical procedure that involves the insertion of a thin, flexible tube called a colonoscope into the rectum and through the large intestine (colon). This procedure allows doctors to examine the lining of the colon and rectum for abnormalities, such as polyps, tumors, and ulcers. Colonoscopy is commonly used to screen for colorectal cancer, which is the third leading cause of cancer-related deaths in the United States. It can also be used to diagnose and treat other conditions affecting the colon, such as inflammatory bowel disease (IBD) and diverticulitis.
During a colonoscopy, the patient is usually given a sedative to relax and minimize discomfort. The colonoscope is then inserted into the rectum and advanced through the colon. The doctor can view the colon's lining through the colonoscope's camera, and any suspicious areas can be biopsied for further examination. Colonoscopy is generally safe and effective, but there are some potential risks, such as bleeding, perforation of the colon, and infection. However, these risks are rare, and the benefits of colonoscopy outweigh the risks for most individuals.

Types Of Colonoscopy
Optical Colonoscopy
Traditional method using a thin, flexible tube with a camera on the end to visualize the entire colon and rectum.
Allows for biopsies, polyp removal, and other interventions.
Virtual Colonoscopy (CT Colonography)
Non-invasive imaging technique using computed tomography (CT) scans to create detailed cross-sectional images of the colon and rectum.
Less invasive than optical colonoscopy, but less accurate in detecting small polyps.
Wireless Capsule Colonoscopy
Ingestible capsule containing a miniature camera that takes thousands of images as it travels through the digestive tract. Non-invasive and well-tolerated, but may not provide as much detail as optical colonoscopy.
Double-Contrast Barium Enema
Radiological procedure using barium sulfate to create a contrast-filled image of the colon and rectum. Less invasive than optical colonoscopy, but may not be as accurate in detecting small polyps.
Flexible Sigmoidoscopy
Similar to optical colonoscopy, but only examines the lower portion of the colon (sigmoid colon and rectum). Less invasive and shorter procedure time than optical colonoscopy.
Anoscopic Examination
Examines only the anal canal and lower rectum using a short, rigid tube with a light on the end. Used for diagnosing conditions such as hemorrhoids, fissures, and anal warts.

Treatment Approaches at Gastroworld Clinic
Diagnostic Colonoscopy
Used to examine the colon and rectum for abnormalities, such as polyps, tumors, or inflammation. Involves inserting a thin, flexible tube with a camera into the colon.
Screening Colonoscopy
Recommended for individuals over 50 to detect and remove precancerous polyps or early-stage cancers. Similar to diagnostic colonoscopy, but focuses on identifying.
Therapeutic Colonoscopy
Used to treat gastrointestinal conditions such as bleeding, polyps, or blockages. Involves using specialized instruments to remove or repair abnormalities .
Virtual Colonoscopy
A non-invasive alternative to traditional colonoscopy that uses CT scans to create detailed images of the colon and rectum. Suitable for individuals who cannot undergo traditional colonoscopy .
Capsule Colonoscopy
Involves swallowing a capsule containing a camera that takes images of the colon and rectum as it passes through. Less invasive than traditional colonoscopy, but may not provide as detailed images.
Double-Balloon Enteroscopy (DBE)
Used to examine the small intestine, which is not accessible during traditional colonoscopy. Involves using a specialized endoscope with two balloons that inflate and pull the small intestine into view.

Frequently Asked Questions
A colonoscopy is a medical procedure that involves inserting a thin, flexible tube with a camera on the end into the rectum and colon to examine the large intestine.
Colonoscopies are typically performed to: Screen for colon cancer Diagnose digestive problems, such as bleeding or abdominal pain Remove polyps or other abnormalities Treat certain medical conditions, such as inflammatory bowel disease
Before a colonoscopy, you will need to: Follow a clear liquid diet for 1-2 days before the procedure Take a bowel preparation to cleanse your colon Stop taking certain medications, such as blood thinners
During a colonoscopy, you will lie on your side on a table. The doctor will insert the colonoscope into your rectum and advance it through your colon. The doctor will use the camera on the scope to examine the lining of your colon and look for any abnormalities.
Colonoscopies are generally safe, but there are some potential risks, such as: Bleeding Infection Perforation (a tear in the colon) Reaction to sedation or anesthesia
