Gastritis with intestinalization is the conclusion of pathological tests performed by the patient during gastroscopy. Intestinalization refers to gastritis in the repair process of inflammation in which gastric epithelial cells are replaced by intestinal epithelial cells intestinalization, which can be strictly divided into the concepts of complete intestinalization and incomplete intestinalization, and whether it is large intestinalization or small intestinalization. If complete small intestinal chemosis is not a problem, but many hospitals cannot strictly distinguish whether it is complete small intestinal chemosis or incomplete large intestinal chemosis, but simply report intestinal chemosis, and the degree of intestinal chemosis is mild, moderate and severe, so there is no way to completely identify it. In case of moderate to severe intestinalization, even some patients appear to have heterogeneous cells suggesting that the symptoms of gastritis are more serious and there may be a risk of early cancer, such patients should be strictly monitored by gastroscopy, and 3-6 months after taking medication, the patient can be instructed to perform gastroscopy again and pathological biopsy to clarify the trend of intestinalization development. It is also necessary to control the diet, reduce irritating diet and rough diet, reduce the intake of pickled food and overnight food, improve the patient’s immunity and resistance, and assist some medication to improve the intestinal chemistry. However, not all enteritis means cancer, and some patients with enteritis can be reversed, so there is no need to be very nervous about gastritis with enteritis, and doctors will treat it according to the degree of enteritis.
