Colonoscopy

Colonoscopy is a safe, effective method of examining the full lining of the colon and rectum, using a long, flexible, tubular instrument using an instrument called a colonoscope. It is used to diagnose colon and rectum problems and to perform biopsies and remove colon polyps (polypectomies). Most colonoscopies are performed as an outpatient, with minimal inconvenience and discomfort.


Who should have a colonoscopy?

Colonoscopy may be recommended to adults 50 years of age or older who are found to have tiny traces of blood in stool samples submitted as part of the Bowel Screening Program. Patients with a family history of colon or rectal cancer may also need to consider having a colonoscopy, even if they do not have any bowel symptoms. Your doctor may also recommend a colonoscopy examination if you have had a change in bowel habit or you have noticed rectal bleeding. These symptoms indicate a possible problem in the colon or rectum. A colonoscopy may be necessary to:

How is colonoscopy performed?

The bowel must first be cleared of all residue before a colonoscopy. This is done before the exam with special laxatives prescribed by your doctor. Most patients opt for intravenous sedation, or “conscious sedation” for this procedure. This means that they may be a little drowsy but the aim is not to make them fully unconscious.


If you are anxious about the procedure, you can request full sedation/general anaesthesia which is administered by an anaesthetist.


If any abnormality is identified, biopsies can be taken or polyps can be removed. The entire procedure usually takes less than 30 minutes.

 Most patients can resume their regular diet and activities the same day. If they have had sedation, they should not drive, operate machinery or sign any legal documents for the rest of the day.


What are the benefits of colonoscopy?

Colonoscopy is more accurate than an x-ray or CT scan of the colon to detect polyps or early cancer. With colonoscopy, it is may also be possible to detect and remove most polyps without abdominal surgery. Removing polyps is an important step in the prevention of colon cancer. Colonoscopy also allows your consultant to assess the severity and extent of colitis.


What are the risks of colonoscopy?

Colonoscopy is generally a very safe procedure with complications occurring in less than 1% of patients. These risks include bleeding, a tear in the intestine, risks of the sedation and failure to either complete the examination or failure to detect a polyp or other pathology.


Should I have a private colonoscopy in the Glasgow Colorectal Centre ?

He is able to get a full assessment of the entire colon in more than 95% of the procedure he undertakes. He also performs colonoscopy as part of the NHS Colorectal Cancer Screening program. He is experienced at advanced & therapeutic colonoscopy including complex polypectomies, endoscopic mucosal resection (EMR) and dilatation (opening up) of colonic strictures etc.
