胃粘膜肠上皮化生是指胃粘膜出现肠型上皮的现象(简称肠化)。肠化与胃癌的关系已有不少研究,但所得结论仍不完全一致。多数认为肠化与肠型胃癌有直接关系,主张肠型胃癌由肠化上皮癌变而来,肠化属癌前病变。少数则认为肠化是一种伴发现象,不属癌前病变。近年来,随着粘液组化研究的深入开展,有的作者将胃粘膜肠化分为两型:小肠型和结肠型。并认为结肠型肠化与肠型胃癌关系密切,属癌前病变,而小肠型肠化则是胃粘膜损伤的非特异反应。本文目的在于通过40岁以上胃良、恶性病例胃粘膜
Gastric mucosal intestinal metaplasia refers to the appearance of intestinal epithelium in the gastric mucosa (abbreviated as intestinal metaplasia). The relationship between intestinal metastasis and gastric cancer has been studied, but the conclusions are still not completely consistent. Most people think that intestinal metaplasia has a direct relationship with intestinal type gastric cancer. It is advocated that intestinal type gastric cancer is transformed from intestinal metastatic epithelial carcinoma, and intestinal metaplasia is precancerous lesion. A few think that intestinal metaplasia is a kind of associated phenomenon and it is not a precancerous lesion. In recent years, with the in-depth development of mucus histochemistry, some authors have divided the intestinal mucosa into two types: intestinal and colonic. It is considered that colonic intestinal metaplasia is closely related to intestinal type gastric cancer and is a precancerous lesion, while intestinal intestinal metaplasia is a nonspecific reaction of gastric mucosal damage. The purpose of this article is to pass the gastric mucosa of benign and malignant cases over 40 years old.
