Gastroenterology Forum authors: Prof Reid Ally, Dr Keith Pettengell and Dr John Wright Irritable bowel syndrome (IBS) is one of the commonest diagnoses made by both primary care physicians and gastroenterologists. In order to treat successfully, an understanding of the pathophysiology is essential. IBS is defined as chronic abdominal symptoms of bloating, altered bowel habit and […]
Gastroenterology Forum authors: Prof Reid Ally, Dr Keith Pettengell and Dr John Wright It is now 25 years since Thomas Brody, a gastroenterologist from Sydney, published the details of his trial on the first successful treatment regimen for Helicobacter pylori and it is rather a shame that his contribution is less well known than his Australian […]
Gastroenterology Forum authors: Prof Reid Ally, Dr Keith Pettengell and Dr John Wright Ascites’ development heralds the onset of liver decompensation and poor long-term outcome without transplantation. Causes The main contributing factor to ascites in cirrhosis is splanchnic vasodilation. As portal hypertension progresses due to increased intra-hepatic resistance, blood is shunted into the systemic circulation. This […]
Dr Keith Pettengell Some medical reports are inherently more accepted and believed than others. One has the feeling that abdominal CAT scan reports by a newly qualified radiologist should be taken rather more seriously than an EEG report by a professor of electrophysiology. Endoscopy reports are rated quite highly in the believability stakes. However, where upper […]
Gastro forum authors: Prof Reid Ally, Dr Keith Pettengell and Dr John Wright In the last 30 years, five proton pump inhibitors (PPIs) have become available in SA (omeprazole, esomeprazole sodium, lansoprazole, pantoprazole, rabeprazole and their associated generics). The differences between these molecules are well described in the literature and promotional material, but the clinical significance […]
Reports suggest that between 10%-40% of patients with gastro oesophageal reflux disease (GORD) fail to respond symptomatically, either partially or completely, to a standard proton pump inhibitor (PPI) dose. It is interesting to note that the number of patients on double-dose PPI has increased dramatically, without evidence that such practices have improved patients’ symptoms. Failure […]
Gastro forum authors: Prof Reid Ally, Dr Keith Pettengell and Dr John Wright Occult gastrointestinal bleeding is bleeding of which a patient is unaware and includes those with a positive faecal occult blood and/or iron deficiency anaemia. The prevalence of the problems is unknown and seeing that most people in the community are not tested for […]
Gastro forum authors: Prof Reid Ally, Dr Keith Pettengell and Dr John Wright In order to improve and standardise treatment for difficult conditions, it has become common to design guidelines for clinicians to follow. In spite of these good intentions, the care given to patients is often suboptimal for the individual. The reasons for this are […]
Prof Reid Ally would like to acknowledge Dr Nazeer Ahmed Ismail Chopdat and the Department of Medical Gastroenterology, Chris Hani Baragwanath Academic Hospital, for contribution to this article Alcoholic liver disease remains a challenging problem for both basic scientists and clinicians. The true prevalence of alcoholic hepatitis is not well defined. In the US alone, it is estimated […]
