A colonoscopy allows your gastroenterologist to look at your large bowel. It’s used as part of bowel cancer screening, to check for cancer or to find out about persistent diarrhoea, bowel movement changes, lower stomach pain or passing blood or mucus from your back passage.
A colonoscope is a long, thin, flexible tube with a camera on the end. A colonoscopy is usually done as an outpatient procedure, under local anaesthetic and takes up to an hour.
It can detect polyps (small non-cancerous growths) in your bowel, diagnose bowel cancer and confirm conditions such as Crohn's disease and ulcerative colitis.
A gastroscopy, or upper gastrointestinal endoscopy, allows your gastroenterologist to see inside your oesophagus, stomach and duodenum. It’s often requested to investigate indigestion problems.
It involves passing a thin, flexible tube with a camera and light source through your mouth to see the organs. A gastroscopy is performed as a day case procedure under local anaesthetic.
A gastroscopy checks these organs for any abnormalities. For example, it’ll detect damage to the lining of your oesophagus or stomach or if you’ve ulcers in your stomach or duodenum.
Lactose intolerance quick test
If we need to determine if you’re intolerant to lactose we can perform a lactose intolerance quick test, called a Biohit lactose Intolerance test, during a gastroscopy. It involves taking a biopsy specimen and testing for activity of the lactase enzyme. It’s a fast and simple test and results are ready within 20 minutes. It can rule out lactose intolerance in IBS and dyspepsia and also assess the degree of lactase deficiency if you’ve coeliac disease.
An endoscopy uses an endoscope, a long, thin, flexible tube with a camera and light source, to see inside your body.
A flexible sigmoidoscopy looks inside your rectum and your sigmoid colon (end portion of the large intestine). It’s used to determine the cause of bowel movement changes or rectal pain and to check for inflammation, polyps and early signs of cancer.
A thin, flexible, tube with a camera, called a sigmoidoscope, is passed into your back passage. During the examination biopsies can be taken, polyps can be removed and haemorrhoids can be treated. A flexible sigmoidoscopy normally takes approximately 15 minutes as an outpatient procedure.
