The findings of intestinal polyps may include: inflammatory polyps, adenomatous polyps, hyperplastic polyps, polyposis or polyp syndrome. 1. Inflammatory polyps: Inflammatory polyps are one of the most common benign intestinal polyps in the clinic, which are formed by long-term chronic inflammatory reaction stimulating the intestinal mucosal epithelium, and can be secondary to a variety of intestinal inflammatory or infectious diseases, such as amoebic enteritis. Generally there is no tendency of malignant change. 2. Adenomatous polyps: adenomas are benign intestinal tumors, but with different degrees of malignant tendency, usually the more villous components of adenomas, the greater the possibility of malignant transformation, the diameter of adenomas larger than 2 cm malignant transformation rate of about 50%. 3. Hyperplastic polyp: hyperplastic polyp is the chronic hyperplasia of intestinal mucosa to form superfluous organisms, it is a kind of non-tumor polyp, the diameter is less than 5mm. 4. Polyposis and polyp syndrome: polyposis refers to the presence of more than 100 polyps in the intestinal tract with special clinical manifestations, including familial adenomatous polyposis, hyperpigmented polyp syndrome, intestinal polyposis combined with multiple osteomas, etc., most of the malignant tendency is obvious, in particular, the familial adenomatous polyposis almost 100% will develop into colorectal cancer. In addition to the above pathologic types, biopsy of intestinal polyps may also reveal juvenile polyps, misshapen polyps, pyogenic polyps, intestinal mucosal prolapse, etc. It is recommended that the patient undergoes pathologic examination to clarify the nature of the polyp, and then take timely intervention to reduce the risk of malignant changes.
