胃粘膜肠上皮化生(简称肠化)是指胃粘膜出现肠型上皮的现象。胃溃疡、慢性胃炎和胃癌时常有胃粘膜肠化,尤以慢性萎缩性胃炎和胃高分化管状腺癌时多见。我们在纤维胃镜活检中,发现1/3的萎缩性胃炎病例伴发肠化(内10％为重度肠化),表浅性胃炎伴发肠化者仅18.3％,且无1例重度肠 Gastric mucosal intestinal metaplasia (abbreviated as intestinal metaplasia) refers to the appearance of intestinal epithelium in the gastric mucosa. Gastric ulcers, chronic gastritis, and gastric cancer often have intestinal mucosal intestine, especially chronic atrophic gastritis and gastric highly differentiated tubular adenocarcinoma. In our gastroscopy biopsy, we found that 1/3 of the cases of atrophic gastritis were associated with intestinal metaplasia (with 10% of the patients having severe intestinal metaplasia), and only 18.3% of patients with superficial gastritis accompanied by intestinal metaplasia and no severe bowel
