Procedures performed in a hospital


Is a procedure done with a gastroscope (8mm instrument) to examine the oesophagus, stomach and duodenum for conditions like reflux, ulcers, infections (Helicobacter), Coeliac disease and Lactase deficiency. 

The usual preparation is fasting for 6-12 hours prior to the procedure. It is performed under light but complete sedation performed by an anaesthetist. It usually takes 10 to 15 minutes.

The term "colonoscopy" means looking inside the colon to the ileum. A colonoscopy is more precise than a scan (virtual CT colonoscopy). The procedure allows an instrument to be passed through the colon. This may be used to painlessly remove a suspicious-looking growth or to take a biopsy (a small piece for further analysis).

Colonoscopy is a relatively safe and effective way to evaluate problems such as bleeding, abdominal pain, changes in bowel habits such as chronic diarrhoea, iron deficiency, positive occult blood and family history.

Colonoscopy is also an important way to look for colon cancer and to treat colon polyps - abnormal growths on the inside lining of the intestine. Polyps vary in size and shape. Most are not cancerous, but some may turn into cancer. However, this is why colonoscopy is often used to remove polyp (polypectomy). Like all procedures, these can be associated with a small risk (bleeding / perforation).

The preparation consists of 36 hours of clear liquids only plus addition of laxative. This varies from person to person and timing of procedure. Usually 3 sachets of picoprep spaced 2-3 hours apart; or 2.5  litres of glycoprep +/- dulcolax the afternoon before the procedure. Blood thinners (Aspirin, Warfarin, Plavix, Fish oils ) are if possible discontinued for a defined period. The procedure is performed under light but complete sedation performed by an anaesthetist. Nil by mouth for 6 hours before the proceduce. 

A written report is given after the procedure. Follow up, if needed, will be recommended at that time.
