Whether intestinal polyps 0.3 cm need to be removed depends mainly on the nature of the polyp, to determine whether it is a tumor, inflammation or hyperplastic polyps. 1. Tumor polyps: usually adenomatous polyps, suspected of being tumor polyps, can be resected based on the experience of naked eye observation, and then do pathological examination to determine. 2. Inflammatory polyps: Inflammatory polyps require active treatment of the primary disease, after the inflammation subsides, the polyp usually disappears and does not require special treatment. 3. Hyperplastic polyps: Hyperplastic polyps do not have uncomfortable feeling, it is recommended to have regular checkups, rapid growth in a short period of time, need immediate surgical treatment. Intestinal polyps with a diameter of less than one centimeter, relatively speaking, the possibility of malignant transformation is very small, it is recommended that you can also be regularly rechecked, visit the gastroenterology department of the regular hospital. Because the naked eye sometimes can not determine whether the polyp may be malignant, for only 0.3cm of intestinal polyps, can be directly resected and then do pathological examination. Because the polyps are smaller at this time, there are fewer surgical complications.
