Distinguishing the nature of rectal polyps is an important guarantee for the choice of surgical treatment plan, as well as the prognosis of patients. ① Brittleness: during the examination, those who bleed very easily when touched with a speculum or instrument are mostly malignant polyps. Conversely, they are benign. ②Ulceration: polyps usually do not have ulcers, but when malignant, ulcers can be formed, especially polyps with tips usually do not cause ulcers, once ulcers occur, it indicates that they have malignant changes. ③Activity: firm, solid, non-tipped polyps are susceptible to malignant change; while those with active tips are relatively less malignant. ④ Shape: lobulated polyps are prone to malignant changes, while smooth and rounded ones are less likely. ⑤ Basal: polyps with large bases and small heads are highly susceptible to malignancy. ⑥Type: Those with a tip are mostly tubular adenomas, which have a relatively low cancer rate. ⑦Size: polyps that increase or polyps that are larger are prone to malignancy, while polyps that do not increase significantly are less likely to be malignant. What should I pay attention to after finding rectal polyps? In life, some people are aware that they suffer from rectal polyps, but do not care much. In fact, if you take it lightly, there are often many adverse consequences that you will regret for the rest of your life. Therefore, it is important to pay attention to the treatment of the disease, to help prevent the malignant change of the disease. Rectal polyps are not solitary: we often see cases of rectal polyps, and when there are polyps in the rectum, there are also polyps in the colon, and most of them are in the combination of rectum and sigmoid colon. Therefore, for those who are found to have rectal polyps, further fiberoptic colonoscopy should be performed for a comprehensive examination of the entire colon to determine the extent and location of polyps. ②Biopsy: When using fiberoptic colonoscopy to examine the intestine, biopsy samples should be taken from each suspicious point in order to further diagnose the nature of the lesion. ③ Timely and thorough treatment: Checking the benignity and malignancy of polyps is only relevant to the surgical method and its surgical scope, while patients themselves, regardless of whether their polyps are benign or not, should be taken seriously and should be detected and treated early. Regular review: Due to the different nature of polyps, recurrence and malignant rate are different, therefore, regular review is necessary to understand the postoperative situation early.
