采用内窥镜直视下粘膜活检和组织病理学检查方法，对河南食管癌高发区楼村普查期间接受胃镜检查的２２６名３０岁以上居民贲门和胃窦粘膜上皮病变进行比较分析。结果：贲门粘膜上皮肠上皮化生和间变发生率明显高于同一人群的胃窦粘膜上皮病变发生率。提示：这一地区人群贲门和胃远侧部位上皮癌变可能存在不同的发病因素和发病机理。
Using mucosal biopsy and histopathological examination under direct vision, the gastric cardia and antrum mucosa epithelial lesions of 226 patients over the age of 30 who underwent gastroscopy during the general survey of the high-incidence area of Henan province were analyzed. RESULTS: The incidence of intestinal metaplasia and metastasis in the mucosal epithelium of the cardia was significantly higher than that of the antrum mucosal epithelium in the same population. Hint: There may be different pathogenesis and pathogenesis of epithelial canceration in the gastric cardia and distal stomach in this region.
