Heterotopic gastric mucosa (HGM) located in the proximal esophagus is referred
to as “inlet patch.” Although its prevalence is reported to
be around 4%, the inlet patch is infrequently biopsied. Therefore, studies
of its demographic and clinical associations have relied on small numbers
of patients and the prevalence and significance of intestinal metaplasia
in HGM has remained unclear.
The aim of our study was to investigate the clinical significance of HGM
with and without intestinal metaplasia in a large group of patients.
