Colonoscopy (Large Intestine and Rectum Examination)

Comprehensive Gastrointestinal Care at Global Gastro and Liver Centre

Colonoscopy is a specialized endoscopic procedure used to examine the large intestine (colon) and rectum for abnormalities, including inflammation, polyps, ulcers, and early signs of colorectal cancer. At Global Gastro and Liver Centre, we provide advanced, safe, and minimally invasive colonoscopy services using the latest technology and highly experienced gastroenterologists.

Colonoscopy plays a vital role in early detection, prevention, and management of colorectal diseases, helping patients maintain optimal digestive health.

What Is Colonoscopy?

Colonoscopy involves the use of a thin, flexible tube called a colonoscope equipped with a camera and light at its tip. The colonoscope is gently inserted through the rectum to examine the entire colon and rectum for abnormalities.

The procedure allows the gastroenterologist to:

Visually inspect the inner lining of the colon and rectum
Identify polyps, tumors, ulcers, or bleeding sites
Take tissue samples (biopsies) for further testing
Remove polyps or small growths during the same session

Colonoscopy is considered the gold standard for colon examination due to its high accuracy and ability to provide both diagnosis and treatment.

Why Is Colonoscopy Needed?

Your doctor may recommend a colonoscopy in the following situations:

Screening for colorectal cancer (especially after age 45 or in high-risk individuals)
Evaluation of persistent diarrhea or constipation
Investigation of unexplained abdominal pain or bloating
Presence of blood in stool or black, tarry stools
Family history of colon polyps or colorectal cancer
Monitoring of inflammatory bowel diseases such as Crohn’s disease or ulcerative colitis
Follow-up after previous polyps or colon surgery

Early detection of colon polyps and other abnormalities significantly reduces the risk of colorectal cancer and enables timely treatment.

How Colonoscopy Is Performed

At Global Gastro and Liver Centre, colonoscopy is performed using state-of-the-art endoscopic equipment and under strict safety protocols.

Pre-Procedure Preparation

Proper bowel preparation is essential for a successful colonoscopy. Patients are required to:

Follow a clear liquid diet for 1–2 days before the procedure
Take laxatives or bowel-cleansing solutions as prescribed
Avoid solid foods, seeds, or nuts that may obstruct visibility

Your doctor will review your medical history and medications to ensure safety. Blood thinners or certain medications may need to be adjusted temporarily.

Sedation and Monitoring

Most colonoscopies are performed under mild sedation or anesthesia to ensure patient comfort. Vital signs such as heart rate, oxygen levels, and blood pressure are continuously monitored.

Colonoscope Insertion and Examination

The colonoscope is gently inserted through the rectum and guided through the entire colon. The camera provides a high-definition view on a monitor, allowing the gastroenterologist to inspect the colon lining thoroughly.

Biopsy and Polyp Removal

If any suspicious tissue, polyps, or lesions are found, they can be removed or biopsied during the same procedure. This is a major advantage of colonoscopy, as it allows diagnosis and treatment simultaneously.

Completion and Recovery

Once the examination is complete, the colonoscope is withdrawn carefully. The procedure typically takes 20–45 minutes, depending on the findings. Patients are monitored until the effects of sedation wear off, after which they can usually go home the same day.

Benefits of Colonoscopy

Colonoscopy offers numerous advantages:

Early detection of colorectal cancer
Accurate diagnosis of colon and rectal diseases
Polyp removal during the procedure, preventing cancer development
Minimally invasive with no surgical incision
Quick recovery and same-day discharge
Guides further treatment decisions based on biopsy results

Routine colonoscopy can save lives by detecting precancerous changes before they develop into advanced cancer.

Safety and Possible Risks

Colonoscopy is generally very safe, but like any medical procedure, it carries potential risks:

Mild abdominal discomfort or bloating
Temporary cramping or gas
Minor bleeding if a biopsy or polyp removal is performed
Rare complications such as colon perforation or reaction to sedation

At Global Gastro and Liver Centre, we minimize risks through expert care, advanced equipment, and thorough monitoring.

After the Procedure: What to Expect

After colonoscopy:

Mild bloating or cramping may occur, which usually resolves within a few hours
Patients may experience mild throat or rectal discomfort
Most patients can resume normal diet and activities the next day
Results are discussed with the patient, and biopsy reports are available within a few days

Follow-up colonoscopy may be recommended based on findings, family history, or risk factors.

Special Considerations

Colonoscopy is recommended for adults above 45 for routine screening for individuals with risk factors such as family history of colorectal cancer, inflammatory bowel disease, or prior polyps.

Children or younger adults may require colonoscopy for congenital conditions, severe gastrointestinal symptoms, or foreign body removal. Our center provides specialized pediatric and adult care to ensure safety and comfort for all patients.
