Colonoscopy is a procedure which enables the doctor to see the inside lining of your large bowel. There are a number of reasons why you may need a colonoscopy. The most common reasons are positive FOBT test (usually requested by your GP), blood in stools, change in bowel habits etc. It is performed to rule out a problem in your bowel, or after surgery on the bowel, as a regular check up.

In order for a colonoscopy to be successful, your bowel needs to be prepared. This is a process in which you would follow strict dietary instructions in conjunction with a mild laxative to cleanse the bowel to allow the scope instrument to be inserted. In some cases treatment is possible through the instruments, enabling you to avoid an operation, e.g. removal of polyps.

On the day of the colonoscopy, an anaesthetist will administer a sedative injection to the vein to make you comfortable. Most people sleep through the procedure. The colonoscopy is performed while you lie on your left side. The instrument is inserted through the back passage. Most colonoscopies take between 20 and 45 minutes and you wake up shortly after that. You will stay in hospital for a few hours after your procedure to make sure that you recover from the effects of the anaesthetic.

If a lesion is detected on colonoscopy and requires further surgery, this can be arranged at your post colonoscopy appointment.
