Low-grade epithelial sarcomatoid lesions of tubular adenomas have been resected and need to be reviewed periodically for recurrence and relapse. Tubular adenoma is a common benign tumor of colorectum, stomach and esophagus, which belongs to benign lesions. Low-grade epithelial sarcomatoid lesion means that the proliferation heterogeneity within the adenoma is not obvious, i.e., more than 75% of adenomatous cells are morphologically similar to normal adenosine epithelial cells, and it does not belong to pre-cancerous lesions, but there is some recurrence and reoccurrence possibilities, so it needs to be followed up for regular checkups after resection. After the resection of tubular adenoma with low-grade epithelial neoplasia, it is also necessary to eat more vegetables, fruits and other high-fiber and vitamin-rich foods, and as little as possible spicy and stimulating foods, avoiding alcohol and tobacco, and avoiding constipation. When abdominal discomfort occurs, it is recommended to consult a doctor in time and standardize the treatment under the guidance of a professional doctor, so as to avoid delaying the condition.
