The upper gastrointestinal (GI) tract, including the oesophagus, stomach and small intestine, is host to numerous microorganisms. Some reflect gastrointestinal involvement by systemic disease, but others are primary digestive disorders that first present at GI sites. This review focuses on the most common infectious disorders of the upper GI tract encountered in general surgical pathology practice, including viral, bacterial, fungal and parasitic organisms. Clinical and histological features are discussed, as well as useful ancillary diagnostic techniques.
