Abstract:
Objective To compare the differences in mucin-histochemistry and etiology of Barrett's esophagus (BE) intestinal metaplasia (IM) , cardiac intestinal metaplasia (CIM) and gastric antrum intestinal metaplasia (GA-IM). Methods Alcian blue /periodic acid-schiff (AB/PAS) and high iron diamine / alcian blue (HID/AB) histochemical methods were used to classify IM in BE, cardia and gastric antrum, and IM were classified into three subtypes: complete small intestinal type (type Ⅰ ) , incomplete small intestinal type (type Ⅱ) and incomplete colonic type (type Ⅲ). Compared the prevalence of different subtypes of IM in above-mentioned sites, and investigated their relationships among the symptoms of gastroesophageal reflux disease (GERD) and Helicobacter pylori (Hp) infection. Results The prevalence of type Ⅲ IM in long-segment BE (LSBE) and short-segment BE (SSBE) is 75. 0% and 63. 3% respectively, it is significantly higher than that in CIM (23. 1% ) and GA-IM ( 17. 7% ) (P
