Gq. Wang et al., GASTRIC HETEROTOPIA IN THE UPPER ESOPHAGUS (INLET PATCH) IN ENDOSCOPIC SURVEYS IN NORTHERN CHINA, Journal of clinical gastroenterology, 19(4), 1994, pp. 321-324
Upper esophageal gastric heterotopia (inlet patch) has not been report
ed in endoscopic series from China. We describe the occurrence of endo
scopically and histologically typical inlet patches in two endoscopic
surveys of asymptomatic adults in northern China. Because rapid endosc
opic protocols were used, the 0.3-0.4% prevalence of inlet patch in th
ese surveys probably represents a minimum figure for adults in this po
pulation.
