title: Gastric heterotopia in the upper esophagus (inlet patch) in endoscopic surveys in northern China.
abstract: Upper esophageal gastric heterotopia (inlet patch) has not been reported in endoscopic series from China. We describe the occurrence of endoscopically and histologically typical inlet patches in two endoscopic surveys of asymptomatic adults in northern China. Because rapid endoscopic protocols were used, the 0.3-0.4% prevalence of inlet patch in these surveys probably represents a minimum figure for adults in this population.
