Mucosal tubular adenomas usually refer mainly to intestinal mucosal glandular tubular adenomas, which are generally tubular adenomas growing in the intestines and require prompt medical attention upon detection. Intestinal mucosal adenomas may be benign or malignant, the nature of which should be determined by biopsy through puncture and pathological examination. If it is malignant, it should be surgically resected under colonoscopy as soon as possible and followed by other treatments such as chemotherapy (e.g., 5-FU, vincristine, etc.). If the benign adenoma is large and deeply invasive, part of the intestine may need to be resected to reanastomize the intestines, and the patient needs to go to the hospital for regular follow-up after the operation. Therefore, patients should pay attention to their daily habits to prevent intestinal mucosal adenomas, and try to avoid drinking alcoholic beverages, as well as eating fatty or pickled foods. After the treatment of colonic mucosal glandular adenoma, regular follow-up is needed.
