Surgery for moderate enterochemistry refers to the surgical removal of gastric mucosal tissue graded as moderate intestinal epithelial hyperplasia to prevent deterioration of the site of enterochemistry. Enterosis generally refers to gastric mucosal intestinal epithelial hyperplasia, which is a typical pre-cancerous lesion in clinic, and is the phenomenon that the gastric mucosal epithelium is replaced by intestinal epithelial tissues, which is commonly found in all kinds of gastritis, with atrophic gastritis being the most common, and it may be related to Helicobacter pylori infection. Moderate enterosis is the pathological stage, which is mainly manifested by the enterosis area accounting for 1/3 to 2/3 of the area of the pathology section taken. Moderate enterosis can be surgically stripped or resected, often by endoscopic or conventional surgical procedures operated on the advice of a physician. Regular postoperative follow-up gastroscopy is required to monitor for recurrence, and any recurrence should be addressed immediately.
