Mo1824 Pattern of Gastric Intestinal Metaplasia (GIM) in Dyspeptic Adults

Abstract

was categorized as or or eradicated. The study patients were categorized according to the presence of inlet patch as follows: group A, inlet patch positive; group B, inlet patch negative. Intergroup male-to-female ratios, H. pylori infection rate, and the prevalence of gastrointestinal diseases were compared using the Chi square test. Result: The baseline clinical characteristics are shown in Table 1. A total of 487 patients (237 females and 250 males, mean age 53.7 years) were examined. Of these, 47 patients (9.4%) were inlet patch positive (Group A), and 440 patients were inlet patch negative (Group B). The male-to-female ratio was significantly higher in group A than group B. Mean age was not statistically different in group A and group B. The prevalence of gastric atrophy, reflux esophagitis, esophageal hiatal hernia, and Barrett's esophagus were not different in group A and group B. The 47 inlet patches were pathologically examined, and the histological features were inactive atrophic fundic mucosa with mild to moderate mucus neck cell or pyloric gland cell metaplasia and no intestinal metaplasia except one case with H. pylori infection. Conclusion: Endoscopic detection rate of inlet patch was 9.4%. Male gender was risk factor for inlet patch. Pathological characteristics of inlet patch was mostly inactive fundic gastritis with (pseudo) pyloric gland metaplasia.
