Abstract

An algorithmic approach to evaluation of dyspepsia or abdominal discomfort begins with differentiation between peptic ulcer disease and gastroesophageal reflux disease as well as recognition of alarm signs and symptoms for gastric cancer, which are indications for early endoscopy. In the absence of alarm symptoms, most patients should undergo noninvasive testing for H pylori infection with a serologic, urea breath, or stool antigen test. Factors to consider in selection of appropriate testing include reliability, specificity, sensitivity, cost, and local access and expertise. As a general rule, physicians should choose a test that has the best accuracy for the level of testing expertise available. The basic principle underlying testing for H pylori is that patients should not undergo testing unless the physician is willing to treat on the basis of a positive test result. In patients who receive treatment, confirmation of cure is important for preventing further morbidity and reducing risk of transmission of infection.
