Intestinal epithelial hyperplasia stripping surgery, i.e., surgically stripping the part of gastrointestinal epithelial hyperplasia, so as to avoid the deterioration of the hyperplasia area. Intestinal epithelial growth is a pathological change of gastric mucosa, which refers to the appearance of cup-shaped cells similar to intestinal epithelium on the surface of gastric mucosa, commonly found in atrophic gastritis, and is a typical pre-cancerous lesion of the stomach. Intestinal epithelialization peeling surgery is the use of endoscopy to peel off the gastric mucosa that has been intestinalized, and after peeling off, the peeled material needs to be pathologically examined to observe whether there is heterogeneous hyperplasia. For patients with intestinalization need to pay attention to diet, avoid spicy stimulation, in addition to pay attention to quit smoking and alcohol. After the stripping operation, it is necessary to pay attention to regular review of the gastroscope to monitor whether the recurrence, and if the recurrence should be dealt with immediately.
