What is a Colonoscopy?


It is an examination of the large intestines (colon) using a long flexible tube-like instrument known as a Colonoscope.The instrument is passed into the colon via the anus which enables the doctor will be able to see and examine the full lining of the colon and the rectum.

Colon


This examination also enables the doctor to:-Diagnose colon and rectal problems-Perform biopsies-Remove colon polyps


This examination will take 20-30 minutes.After the examination, you will need to rest in the Day Surgeryfor about 2 hours.

Why the need for a good preparation?


There are faecal (waste) matters in the colon. They must be cleared from the colon so that the examination of the colon may be carried out smoothly and accurately.


Should there be any residual faecal matters in the colon, it will result in an incomplete examination and the examination may have to be stopped and repeated at another date. Therefore it is important to follow the instructions of the preparations closely.
