Colonoscopy is a medical procedure that allows a doctor to examine the interior lining of the large intestine (colon) and rectum. It is typically performed to investigate symptoms such as abdominal pain, rectal bleeding, or changes in bowel habits, as well as for screening and prevention of colorectal cancer.
Purpose and Procedure
During a colonoscopy, a thin, flexible tube called a colonoscope is inserted through the rectum and advanced into the colon. The colonoscope has a small camera and light at its tip, which transmits images to a monitor, allowing the doctor to visualize the inner lining of the colon. The procedure is typically performed under sedation to minimize discomfort.
The doctor can examine the colon for any abnormalities, such as polyps (growths on the lining), ulcers, or signs of inflammation or bleeding. If any suspicious areas are found, the doctor can take biopsies (small tissue samples) for further analysis. Polyps can also be removed during the procedure, which helps prevent them from potentially developing into colon cancer.

|---|---|
| Colonoscope | A flexible tube with a camera and light for visualizing the colon |
| Biopsy Forceps | Instruments used to obtain tissue samples for analysis |
| Snare | A wire loop used to remove polyps or abnormal growths |
Colonoscopy is considered a safe and effective procedure, but it does carry some risks, such as bleeding, perforation of the colon, or complications from sedation. Proper preparation and following the doctor's instructions are crucial for a successful and accurate examination.
The Role of Colonoscopy
Colonoscopy is a crucial diagnostic procedure that plays a vital role in the early detection and prevention of colorectal cancer. It enables healthcare professionals to examine the entire colon and rectum for any abnormalities, such as polyps, tumors, or other irregularities. Additionally, colonoscopy is valuable in the evaluation of various gastrointestinal conditions, including inflammatory bowel diseases, bleeding, and unexplained abdominal pain.
Indications for Colonoscopy
Colonoscopy is typically recommended in the following situations:
- Screening for colorectal cancer: Regular colonoscopy screening is recommended for individuals over the age of 45 or those with a family history of colorectal cancer.
- Evaluation of gastrointestinal symptoms: Colonoscopy may be ordered to investigate symptoms such as rectal bleeding, abdominal pain, changes in bowel habits, or unexplained weight loss.
- Monitoring of inflammatory bowel diseases: Patients with conditions like Crohn's disease or ulcerative colitis may require periodic colonoscopies to assess disease activity and monitor treatment response.
- Follow-up after positive screening tests: If other screening tests (e.g., fecal occult blood test or CT colonography) indicate the presence of abnormalities, a colonoscopy may be performed for further evaluation.
- Surveillance after polyp removal: Individuals who have had precancerous polyps removed may need regular colonoscopies to monitor for recurrence and detect any new growths.
Preparation for the Procedure
To ensure accurate results for the colonoscopy procedure, it is essential to follow specific preparation instructions. These may include:
- Following a clear liquid diet: You may be required to consume only clear liquids (such as water, broth, or clear juices) for a certain period before the procedure, typically 24 to 48 hours.
- Bowel preparation: You will need to take a laxative or use an enema to thoroughly cleanse your colon. This helps ensure a clear view during the colonoscopy.
- Medication adjustments: Inform your healthcare provider about any medications you are taking, as some may need to be temporarily adjusted or stopped before the procedure.
- Arranging for transportation: You will receive sedation during the colonoscopy, so you must arrange for someone to drive you home after the procedure.
The Procedure
During a colonoscopy, a long, flexible tube with a camera on the end (colonoscope) is inserted through the rectum and advanced into the colon. The healthcare provider can then examine the lining of the colon and rectum for any abnormalities, such as polyps or signs of cancer. If necessary, tissue samples (biopsies) or removal of polyps can be performed during the procedure.

IMPORTANT!
It is crucial to remember that the information provided in this section is not intended for self-diagnosis or treatment. If you experience any symptoms or exacerbation of a condition, it is essential to consult a physician for proper diagnostic testing and treatment. Only a qualified medical professional can accurately diagnose and prescribe appropriate treatment. To ensure the most accurate and consistent evaluation of test results, it is recommended to have them conducted at the same laboratory. This is because different laboratories may use varying methods and units of measurement for similar tests.
