When should endoscopy (or radiology) be used in dyspepsia and peptic ulcer disease?

Abstract

It is now possible readily to investigate dyspeptic symptoms using either a double-contrast barium meal or upper gastrointestinal endoscopy. The accuracy of endoscopy makes it preferable for routine use. As oesophagogastro-duodenoscopy (OGD) is invasive, some risks (albeit very small) are involved. Moreover, this technique has some weaknesses. For these reasons, selection of patients is important. Organic disease is most likely to occur in older patients: anyone presenting with dyspepsia for the first time over the age of 40 years should be investigated automatically. In individuals under 40 years of age, organic disease is less common and some selection criteria should be applied to reduce the number of negative investigations. After age, smoking is probably the single most important adverse factor. For gastric ulcer, endoscopy with biopsy, repeated after a course of therapy, is routine, but for duodenal ulcer repeat examination need not normally be undertaken owing to the effectiveness of modern healing drugs. Methods for improving the diagnostic accuracy of patient histories and clinical examinations need to be developed in order to utilize diagnostic investigations more efficiently for the patients' benefit.
