This is a procedure which allows the doctor to see inside your oesophagus, stomach, and the first part of the small intestine (duodenum) and examine the lining directly. What to expect The gastroscope is a plastic-coated tube about as thick as a ballpoint pen and is flexible. It has a tiny camera attached that sends images to a viewing screen. During the test you will swallow the tube but the back of your throat is sprayed with anaesthetic so you don’t feel this. You will be offered a sedative (medicine that will make you sleepy but is not a general anaesthetic) as well. If the doctor sees any abnormalities they can take a biopsy (a small piece of tissue) to send to the laboratory for testing. This is not a painful procedure and will be performed at the day stay unit in a theatre suite (operating room) by a specialist doctor with nurses assisting. Complications from this procedure are very rare but can occur. They include: bleeding after a biopsy, if performed an allergic reaction to the sedative or throat spray perforation (tearing) of the stomach with the instrument (this is a serious but extremely rare complication). Before the procedure You will be asked not to eat anything from midnight the night before and not to take any of your medications on the day of the procedure. After the procedure You will stay in the day stay unit until the sedation has worn off which usually takes 1-2 hours. You will be given something to eat or drink before you go home. If you have been sedated, you are not to drive until the following day. If biopsies are taken these will be sent for analysis and results are available within 2-3 weeks. A report and copies of these are sent to your GP.

This is a procedure which allows the doctor to see inside your large bowel and examine the surfaces directly and take biopsies (samples of tissue) if needed. Treatment of conditions can also be undertaken. What to expect The colonoscope is a flexible plastic-coated tube a little thicker than a ballpoint pen which has a tiny camera attached that sends images to a viewing screen. You will be given a sedative (medicine that will make you sleepy but is not a general anaesthetic). The tube is passed into the rectum (bottom) and gently moved along the large bowel. The procedure takes from 10 minutes to 1 hour and your oxygen levels and heart rhythm are monitored throughout. The procedure is performed in a day stay operating theatre. Before the procedure You will need to follow a special diet and take some laxatives (medicine to make you go to the toilet) over the days leading up to the test. Risks of a colonoscopy are rare but include: bleeding if a biopsy is performed allergic reaction to the sedative perforation (tearing) of the bowel wall.

Peptic ulcers are sores or eroded areas that form in the lining of the digestive tract. They usually occur in the stomach (gastric ulcer) or in the duodenum (duodenal ulcer), which is the first part of the small intestine. People with peptic ulcers can have a wide variety of symptoms and signs, can be completely symptom-free or, much less commonly, can develop potentially life-threatening complications such as bleeding. Signs and symptoms of ulcers include: pain / burning or discomfort (usually in the upper abdomen) bloating an early sense of fullness with eating lack of appetite nausea vomiting bleeding, which is made apparent by blood in the stool, either in noticeable or microscopic amounts (very brisk bleeding will result in black and tarry stools that smell bad). Smoking, alcohol, anti-inflammatory medication and aspirin increase the risk of developing ulcers. Psychological stress and dietary factors (once thought to be the cause of ulcers) do not appear to have a major role in their development. Helicobacter pylori, a bacteria that is frequently found in the stomach is a major cause of stomach ulcers. If this is found you will be given a course of antibiotics. Diagnosis is made by the history, examination and sometimes blood tests. You may be asked to have a gastroscopy (see above) to clarify the diagnosis and aid with treatment. Treatment consists of medication to reduce the amount of acid in the stomach which aids in the healing of ulcers and avoidance of things that cause ulcers in the first place.

There are two types of IBD, ulcerative colitis and Crohn’s disease. In these conditions, the immune system attacks the lining of the colon causing inflammation and ulceration, bleeding and diarrhoea. In ulcerative colitis this only involves the large intestine, whereas in Crohn’s disease areas within the entire intestine can be involved. Both diseases are chronic (long term) with symptoms coming (relapse) and going (remission) over a number of years. Symptoms depend on what part of the intestine is involved but include: abdominal pain diarrhoea with bleeding tiredness fevers infections around the anus (bottom) weight loss can occur if the condition has been present for some time. Diagnosis is made when the symptoms, examination and blood tests suggest inflammatory bowel disease, infection is ruled out, and you undergo a colonoscopy with biopsy. Treatment depends on the severity of the symptoms and what part of the intestine is affected. Medication is aimed at suppressing the immune system, which is harming the lining of the bowel. This is done via oral or intravenous medication as well as medication given as an enema (via the bottom). Other treatments include changes in the diet to optimise nutrition and health. Treatment in some cases requires surgery to remove affected parts of the bowel. For more information see www.crohnsandcolitis.org.nz
