Enterosis generally refers to intestinal epithelial hyperplasia of the gastric mucosa, which is a precancerous lesion. Generally, mild intestinalization is not serious, but it still needs timely treatment and regular review. Intestinal epithelial hyperplasia is a pathological change, which refers to the replacement of gastric mucosal epithelium by intestinal epithelial cells, and it is a kind of precancerous lesion of the stomach, which often occurs on the basis of chronic atrophic gastritis. Intestinal chemosis has a certain risk of developing into gastric intraepithelial neoplasia or even gastric cancer. Those who present with intestinal epithelial metaplasia need to undergo pathological examination to determine the type of intestinal metaplasia, and different types of metaplasia have different tendencies to develop into gastric cancer. Generally speaking, colorectal type chemosis or incomplete intestinal epithelial chemosis with poor epithelial differentiation is related to the development of gastric cancer. Those who have intestinal chemosis need to be actively treated under doctor’s guidance to avoid progression of the disease. Those who have intestinalization need to take a light diet and do not eat spicy food that stimulate gastric mucosa. People with H. pylori infection should actively use quadruple drug therapy to eradicate H. pylori according to the treatment program, which may help to reverse enterochemistry. In addition, those with enterocolitis need to undergo regular gastroscopy to monitor for the development of cancer, and should be treated immediately if it occurs.
