[Changes of gastric pits in intestinal metaplasia of gastric mucosa].

To analyze the changes of gastric pits in intestinal metaplastic mucosa in 20 specimens of subtotal gastrorectomy and to evaluate the relationship between intestinal metaplasia and gastric pits. We made stereomicroscopic observation of the resected parts of the stomach by using dye-staining method. The width of gastric pits was measured by microscope and the histopathological examination was carried out. The features were divided into two groups: intestinal metaplasia and simple chronic superficial gastritis. The stereomicroscopic features of gastric pits were observed in 15.38% type BC, 28.21% type C, 25.64% type CD and 30.77% type D. The width of gastric pits was significantly different between intestinal metaplasia and simple superficial gastritis, especially obvious in severe intestinal metaplasia. The figures of gastric pits were mostly those a type C and type D and widened gastric pits were more obvious in intestinal metaplastic mucosa than in simple chronic superficial gastritis.
