An intestinal polyp is a bulging lesion on the surface of the intestinal mucosa, commonly known as a fleshy lump growing in the intestinal canal. The large intestine is the most common site for polyps. Since they rarely cause discomfort, bleeding or obstruction, they are often not easily detected and are mostly discovered during physical examinations or checkups for other diseases. As shown in the figure below, 95% of colorectal cancers are transformed from colorectal polyps step by step. This process may take 5 to 10 years, but individual differences vary. Because they generally have no obvious clinical symptoms, only a small percentage of patients with intestinal polyps clinically present with abnormalities such as blood in stool, mucus stool and abdominal pain, and these symptoms also often lack specificity, so to confirm the diagnosis of intestinal polyps, we have to rely on instrumentation such as colonoscopy. Polyps can recur, to be reviewed regularly Polyps are found, even if they are removed, but the environment has not changed, there is still the possibility of recurrence, Ms. Zhang is an example, so regular review is particularly important. Any patient who has ever had a history of colon polyps should be reviewed. If a single polyp is removed and the pathology proves to be benign, only one colonoscopy should be checked once a year at the beginning, and no recurrence for 2~3 consecutive years, which means the probability of recurrence of this person’s polyp is small, and then it can be changed to once every 5~10 years. For postoperative pathology suggesting that polyps with villous adenoma, serrated adenoma and high-grade epithelial neoplasia are prone to recurrence and carcinoma, for the sake of insurance, those who are in a position to do so should be reviewed more closely according to individual conditions. Reminder: To reduce the occurrence of polyps, the diet should pay attention to more green leafy vegetables, tomatoes, eggplant, carrots, etc., which is conducive to intestinal peristalsis. Removal of colon polyps can block the occurrence of colorectal cancer Adenomas are divided into three types: tubular adenomas, villous adenomas and mixed adenomas, with the highest cancer rate of villous adenomas and the lowest cancer rate of tubular adenomas. Adenomatous polyps may be related to genetics, chronic inflammatory irritation, lifestyle habits, chronic constipation and other factors. Adenomatous polyps do not go away on their own and are difficult to be eliminated by medication. If left untreated, they can grow slowly and have a higher chance of developing cancer. Inflammatory polyps are relatively safe, sometimes very small inflammatory polyps will disappear on their own, but inflammatory polyps are stimulated by inflammation for a long time, there is also the possibility of adenoma development. Endoscopic polyp removal is less invasive, shorter hospital stay, and cuts off the path of polyp cancer. Although most doctors can roughly determine the benign and malignant under the naked eye based on their experience, the pathological diagnosis under the microscope after biopsy is the gold standard, among which all intestinal polyps detected should be removed.
