What is Colonoscopy Procedure?
A colonoscopy is a medical procedure that allows doctors to visualise the colon and rectum, helping in the early detection, prevention, and management of colorectal diseases. It has become invaluable in ensuring optimal colorectal health and preventing severe conditions like colorectal cancer.
Colonoscopy involves examining the colon (large intestine) and rectum using a long, flexible tube called a colonoscope. The colonoscope is equipped with a camera and a light source, allowing the doctor to capture real-time images of the colon's interior, which helps in the early detection of colorectal diseases.
What are the Benefits of Colonoscopy?
- Early Detection of Colorectal Cancer: Colonoscopy helps detect precancerous polyps or tumours in the colon. Early detection of these growths increases the likelihood of successful treatment and prevention of cancer development.
- Diagnosis of Colorectal Conditions: Colonoscopy helps diagnose various colorectal conditions, such as inflammatory bowel disease (IBD), diverticulosis, and gastrointestinal bleeding.
- Polyp Removal:
Polyps (abnormal growths) can be identified and removed during the procedure, reducing the risk of them becoming cancerous over time.
- Management of Symptoms: Colonoscopy can help determine the cause of symptoms like unexplained abdominal pain, changes in bowel habits, and rectal bleeding.

What are the Indications of Colonoscopy?
Colonoscopy is commonly performed for diagnostic, screening, and preventive purposes. Here are the key indications for undergoing a colonoscopy:
- Screening for Colorectal Cancer: Colonoscopy is a crucial tool for detecting early signs of colorectal cancer, making it a recommended screening option for individuals at average or increased risk.
- Unexplained Gastrointestinal Symptoms: Persistent abdominal pain, changes in bowel habits, rectal bleeding, unexplained weight loss, or other digestive symptoms might warrant a colonoscopy to identify potential causes.
- Family History of Colorectal Cancer: Individuals with a family history of colorectal cancer or certain genetic conditions that increase cancer risk might require earlier or more frequent colonoscopies.
- Colorectal Cancer Surveillance: Individuals who have previously had colorectal cancer or certain types of polyps may undergo regular colonoscopies to monitor for recurrence or new growth.
- Polyp Detection and Removal: Colonoscopy allows for the detection and removal of polyps, abnormal growths that can potentially develop into cancer over time.
- Screening for Polyps: Regular colonoscopies are recommended to identify and remove precancerous polyps, reducing the risk of colorectal cancer.
- Inflammatory Bowel Disease (IBD) Monitoring: Patients with Crohn's disease or ulcerative colitis may require periodic colonoscopies to assess disease activity and monitor complications.
- Positive Stool-Based Tests: If stool-based tests, such as faecal occult blood tests, indicate possible abnormalities, a colonoscopy might be recommended for further evaluation.
- Anemia Investigation: Colonoscopy may be used to identify the source of unexplained anemia or chronic blood loss in the gastrointestinal tract.
- Surveillance After Surgery: Individuals who have undergone surgery for colorectal conditions might need follow-up colonoscopies to ensure proper healing and monitor for any new issues.
- Unexplained Iron Deficiency: If iron deficiency anaemia occurs without a clear cause, a colonoscopy can help identify potential sources of bleeding.
- Gastrointestinal Bleeding: Colonoscopy is a valuable tool for investigating the source of gastrointestinal bleeding, identifying areas of bleeding, and potentially providing treatment.
- Suspected Colonic Mass or Lesions: When imaging or other tests suggest the presence of abnormal masses or lesions in the colon, a colonoscopy can provide a direct visualization for accurate diagnosis.

Steps Involved in Colonoscopy Procedure
During a colonoscopy procedure, a medical team thoroughly examines the colon and rectum using a specialized instrument called a colonoscopy. This procedure is typically done to screen for colorectal conditions, including detecting polyps, tumors, inflammation, and other abnormalities.
Here's a step-by-step breakdown of what happens during a colonoscopy procedure:
- Pre-procedure Preparation: Before the procedure, you'll receive instructions from your healthcare provider on how to prepare. It usually involves dietary restrictions, laxatives, and a clear liquid diet to ensure the colon is adequately cleansed.
- Arrival and Check-In: You'll check in at the medical facility on the day of the procedure. Medical professionals will review your medical history, ensure you understand the procedure and answer any questions.
- Pre-procedure Monitoring: You'll be taken to a pre-procedure area, where your signs will be checked, and you'll change into a hospital gown.
- Anesthesia and Sedation: In most cases, you'll receive sedation to help you relax and alleviate discomfort during the procedure. Depending on your preferences and medical condition, this can range from mild sedation to more profound anesthesia.
- Positioning: You'll be asked to lie on your side with your knees drawn up towards your chest. This position allows for easier insertion of the colonoscope.
- Insertion of Colonoscope: The colonoscope, a flexible tube with a camera and light source, is gently inserted through the rectum and advanced through the colon.
- Visualization: As the colonoscope advances, the camera sends real-time images to a monitor. The doctor carefully navigates the scope through the entire colon length, examining the lining for abnormalities.
- Air or Water Insufflation: To improve visibility and maneuverability, the doctor might introduce a small amount of air or water into the colon, slightly expanding it.
- Polyp Detection and Removal: If polyps or other abnormalities are detected, the doctor can remove them using specialized instruments. This process is painless and often goes unnoticed by the patient.
- Biopsy (if needed): If an area appears suspicious, the doctor may perform a biopsy, which involves collecting a small tissue sample for further analysis.
- Completion and Withdrawal: After the examination, the colonoscope is gently withdrawn. Depending on various factors, the procedure typically takes 30 to 60 minutes.
