What is a colonoscopy?


Colonoscopy is a medical imaging test where your doctor examines the lining of your large intestine or colon for abnormalities or inflammation, by inserting a thin, flexible tube, as thick as your finger, into the anus. and slowly advancing it through the rectum and colon. This instrument, called an endoscope or colonoscope, consists of a thin and flexible tube 1.5 to 2 m long connected to optical fibers or to a miniature camera, and to a light source to allow your doctor to view the real-time images on a video monitor. In addition, it allows for the insertion of instruments, forceps or an electrosurgical unit to perform biopsies, ablations or remove polyps. The samples collected will then be analyzed in the laboratory to determine the nature of the anomaly. After that, your doctor can start the appropriate treatments.


Why have a colonoscopy?


Among the various medical conditions affecting the large intestine and colon, is colorectal cancer which is considered the third most commonly diagnosed form of cancer in Canada, with an estimated mortality rate of 12% of all cancer deaths, which represents a fairly high mortality rate. This is why colonoscopy is recommended not only to assess symptoms such as bleeding and diarrhea but also to check for possible colorectal cancer. Colonoscopy saves lives in this regard.


When should I see a doctor for a colonoscopy?


In Canada, colonoscopy for colon cancer is usually done at age 50. However, it can be done earlier for some people at higher risk. In all cases, consult your doctor without delay as soon as you notice:

  • frequent abdominal or intestinal pain or cramps that usual treatments fail to calm,
  • blood in the stool
  • changes in intestinal transit (diarrhea or constipation),
  • persistent nausea and vomiting
  • anemia with iron deficiency
  • gastrointestinal disorders

Other symptoms may cause your doctor to order a colonoscopy during your medical consultation. It is therefore important that you maintain optimal gut health.


How should I prepare for a colonoscopy?


In fact, during the medical consultation, your doctor will explain all the stages of colonoscopy to you. Note that this requires a certain cooperation from you and compliance with the letter of your doctor’s recommendations which we summarize in the table below: Preparation for a colonoscopy usually includes the following indications:·

  • Do not take an iron supplement for 7 days before the test.·
  • Follow a diet devoid of fiber, bread, whole pasta, milk, dairy products, citrus juice (lemon, clementine, orange), dark soft drinks (Pepsi, Coke), fruits and vegetables, legumes, chips (crisps, popcorn), sauces, in order to avoid the presence of food residues during the examination.·
  • The day before the exam, drink plenty of clear fluids (water, white grape juice, apple juice) and take laxative products to empty the bowels well before the exam.

Your doctor will give you other instructions depending on the time of your colonoscopy. Please comply with them otherwise you risk compromising the results of the colonoscopy.


How is colonoscopy performed?


Colonoscopy is performed at our clinics in Montreal and Gatineau. Its duration varies from 15 to 45 minutes. It’s not a painful exam. But make sure you have someone with you first, since you will usually not be able to drive after the test due to the sedative being given. You have the option to receive an intervenous sedative to relieve discomfort. You will be asked to lie on your left side and raise your legs. The doctor puts the colonoscope through the anus and slowly and slowly moves it up the rectum and then into the colon. Air will be blown into the colon to allow the doctor to better examine the walls.If necessary, the doctor may insert instruments into the colonoscope to take a biopsy, stop bleeding, or remove polyps.Cramping or a feeling of having a bowel movement is possible, and you may hear and feel gas coming out of the colonoscope.


What happens after the exam?


After the test, you will still feel the effects of the sedative. You will be placed in a place to rest while the effects of the sedation wear off. You may still have abdominal cramps and gas. You should not drive or operate machinery for 24 hours after the exam.When you get home, continue to drink enough fluids to replace the fluids that you have lost but avoid drinking alcohol.Remember to ask your doctor when you can resume your medication and your usual diet.


What are the side effects of colonoscopy?


Colonoscopy is not a painful test and is usually a safe test. However, there are some common side effects that may occur after the test:

  • Irritation of the rectum
  • Bloating
  • Nausea and vomiting
  • Small amount of blood in the stool for the first few days after the test


Some rare side effects are more serious such as:

  • A perforation of the intestine which will be treated with antibiotics or, as the case may be, surgery.
  • An allergic reaction to the sedative or drugs used
  • Heavy bleeding that will require a blood transfusion and hospitalization
