Gastroscopy is for visual observation, biopsy is for cytology, and the exact test for enterochemistry is based on the biopsy. Gastroscopy with enterochemistry but not biopsy means no enterochemistry. Gastroscopy sees lesions in the gastric mucosa that look like enterochemistry, but after removing the tissue and doing a biopsy, it is not enterochemistry. Enterocytosis refers to intestinal epithelial hyperplasia, in which the gastric mucosa undergoes lesions and then grows out of the intestinal mucosa. The gastric mucosa should be reddish and smooth, and due to inflammatory damage, white patchy intestinal mucosa grows after repair and is rougher. Usually intestinal epithelial hyperplasia occurs in atrophic gastritis, and cancer may occur when intestinal hyperplasia further develops into heterogeneous hyperplasia. Gastroscopy with gastric mucosal lesions, there may be gastric ulcer, gastritis, etc., should promptly seek medical attention to clarify the cause of the disease, under the guidance of the doctor for treatment.
