Colonoscopy (or coloscopy)
What’s a colonoscopy
A colonoscopy is an examination of the large intestine by means of direct visualisation of the lining of the colon through a small flexible tube.
The main purpose of the colonoscopy is the detection of polyps which may develop into cancer.
It is performed to detect any anomalies of the colon and if necessary take some tissue samples which will be analysed under a microscope. During the examination, if polyps are discovered, they will be removed or destroyed in order to prevent them from developing into tumors.
How is a colonoscopy done ?
The endoscope is inserted into the anus and is directed all along the colon. Biopsies are sometimes taken; however, this is usually painless.
If there is any discomfort, which varies from person to person based on each individuals’ anatomy, and if this discomfort is not tolerable, we will reschedule this examination and have it conducted under general anaesthesia.
If polyps of a relative size are detected, their removal will have to be scheduled.
Between examinations all instruments are sterilized and some elements are disgarded to avoid any infection.
How do you prepare for a colonoscopy ?
For the examination to be conducted properly the intestine needs to be completely empty. Therefore you will have to strictly follow the instructions you are given which consist of drinking a solution which is intended to empty your colon. You must inform your doctor of any allergies and any medication you are taking, especially those which affect the thinning of your blood (for example: aspirin, anti-inflammatory medication, steroids or Plavix).
What type of discomfort can be experienced during the examination ?
The curve of the intestine may contribute to some discomfort during the procedure. After the procedure you often experience abdominal cramps, however passing of gas will ease this condition.
Which complication can be experienced ?
The colonoscopy does have a few risks involved. A pre-examination and appropriate precautions are taken in order to minimize discomfort and risks. Complications such as a perforation or hemorrhage are rare and are usually associated with the removal of polyps. Even rarer is the occurrence of cardio-respiratory problems.
Complications arise most frequently during the endoscopy. However, they can arise a couple of days after the examination (abdominal pain, loss of blood during bowel movements and fever). It is therefore very important to contact a doctor immediately at 02 762 50 44 (HTC Medicis). In case you are not successful in contacting the doctor, contact your own doctor or go to emergency services at your local hospital.
