An Oesophageal Inlet patch is a small area of heterotopic gastric epithelium in the cervical part of the oesophagus. This finding is common, about 2-4 % of all patients undergoing upper endoscopi have an inlet patch. The finding is considered clinically insignificant, the patch does not cause any symptoms, and there is no risk of cancer. A coincidence of Barrett oesophagus and inlet patch has been found, suggesting some kind of shared embryonic etiology.
