Colonic tubular adenoma 0.6 cm is about a few years long, and patients may undergo surgical removal or endoscopic removal of the colonic tubular adenoma. Colonic tubular adenomas 0.6 cm in diameter are relatively small adenomas, also known as colonic adenomatous polyps, which carry a certain risk of becoming cancerous. Once detected, prompt surgical removal is recommended. Generally, colonic tubular adenomas are treated with colorectoscopic resection and pathologic examination to exclude malignancy. Patients should reduce dietary fiber intake in the early postoperative period to minimize fecal irritation to the surgical area, and avoid spicy, irritating, and greasy foods. After the healing of the wound, dietary fiber intake can be increased to reduce the irritation of dry and hard stools. Patients with a history of colonic adenoma or family history need to be reviewed regularly. Postoperative review is usually every 3 to 6 months.
