Prevalence and time trend of intestinal metaplasia in Hong Kong.

Background And Methods: Upper endoscopy records from 1998 to 2003 were reviewed. The demographic data, endoscopic diagnosis, results of rapid urease test and the absence or presence of intestinal metaplasia (IM) in histology were reviewed, to evaluate the prevalence of IM and Helicobacter pylori (Hp) infection over time in Hong Kong.

Results: Among 1805 endoscopies performed, 1751 had both rapid urease test and histology available.
