Question: What exactly is an intestinal polyp?
Answer: Speaking of an intestinal polyp, it is actually a raised lesion on the surface of the intestinal mucosa. In layman's terms, it is a pimple growing in the intestine. Meat bumps are small at first and may not cause painful symptoms for patients. However, because colon polyps are closely related to the onset of colon cancer, doctors in the gastroenterology department and endoscopy doctors attach great importance to intestinal polyps.
Question: What is the relationship between bowel polyps and bowel cancer?
Answer: Intestinal polyps and bowel cancer are particularly closely related. There is a high incidence of bowel cancer, and bowel polyps are also high. For example, bowel polyps and bowel cancer are both high in the United States. In African countries, bowel polyps and bowel cancer are likely to be low. But these immigrants from African countries, after immigrating to European countries, the next generation tends to increase year by year. In terms of age distribution, intestinal polyps occur about ten years earlier than intestinal cancer. In patients with colon polyposis, the incidence of intestinal polyps is 10-20 years earlier than intestinal cancer. This time interval may be that polyps gradually occur. The process of evolving into cancer. After the age of 40, it is possible that bowel polyps and bowel cancer are both high-incidence trends.
If another familial intestinal polyp is left untreated, because it is a disease related to heredity, if it is left untreated, it will eventually develop into colon cancer. Almost 50% will become cancerous. After 70 years of age, almost 100% will become cancerous. The average age of canceration. He is 39 years old.
In healthy people, the incidence of colon polyps is very high after the age of 70. Generally, more than 50% of people after the age of 70 will have colon polyps. Why do we say that colon cancer and colon polyps are closely related? We found that colon polyps mostly grow in the rectum and sigmoid colon, and colon cancer also grows in the colon and sigmoid colon. And we have surgery for colon cancer patients, we are giving When he had an endoscopy, he was able to find single or multiple colon polyps in the intestine at the same time, and in the surgical specimens removed, polyp tissues could be seen on the margins of the remaining cancer.
Question: Can it be cancerous that can be distinguished from its appearance?
Answer: For example, if it is relatively large, or the surface is erosive or hyperemic, these may have a higher cancer rate. Another is that the cancer rate of the long neck is not so high, and flat polyps are prone to cancer. In addition, the more the number, the higher the possibility of cancer. Just like the familial polyposis we just said, there may be thousands of them, densely packed. This cancer rate is not generally high, but rather high. Another is also related to the location. The left colon has a higher cancer rate than the right colon, because the left colon has a longer storage time and is related to frequent exposure to carcinogens, so the left colon is higher than the right colon. There is still time, because polyps are a process of gradual growth. According to statistics, it takes two to three years for a 0.5 cm polyp to grow to 1 cm. Therefore, the larger the polyp, the higher the cancer rate.
Question: Do intestinal polyps grow in the colon and sigmoid colon?
Answer: No. For example, this is a normal bowel. Our doctors call it the colon. The common people can also call it the large intestine. The large intestine is divided into many parts. The most common occurrence of colon polyps and colon cancer is the rectum and sigmoid colon. However, polyps do not only grow in these two parts, the entire intestine can grow polyps, but these two parts are more common.
Question: What important function does the large intestine play in our human body?
Answer: It mainly absorbs water, microorganisms, and forms feces, which are then excreted.
Question: What is the difference between intestinal polyps and other diseases?
Answer: Some patients with intestinal polyps have symptoms, and some may not have any symptoms for a long time. Generally speaking, symptoms develop when the polyps are relatively large. Diarrhea and abdominal pain are very common in Gastroenterology. For example, functional bowel disease is called irritable bowel syndrome. Such patients have repeated abdominal pain, but his diarrhea is characteristic, usually with mental factors, mental stress, Sleep disturbance can be relieved after he has a bowel movement. Intestinal polyps do not have this characteristic. Intestinal polyps are mostly a kind of dull pain, not very severe. Unless the polyp comes out of the anus, or it is very large, it will cause more pain Symptoms include inflammatory bowel disease, such as dysentery and chronic colitis, and often abdominal pain. However, with this type of acute inflammatory bowel disease, the abdominal pain is more severe and the number of bowel movements is more frequent. There are still certain differences.
Clinical symptoms of intestinal polyps are particularly rare. If symptoms occur, there may be bloody stools, which are caused by ulcers and erosions on the surface of colon polyps. One feature is that the bleeding is relatively small and intermittent, and it is attached to the surface of the stool. Bleeding. In our clinical work, the common blood in the stool is bleeding from hemorrhoids, while the rectal bleeding is blood dripping before or after the stool, and the amount is large. There are also common types of bowel cancer, which can also cause blood in the stool. Some are mixed with stool, or some are jam-like blood in the stool, and bloody stools caused by various inflammations, most of which are mucus, pus, and blood in the stool, and sometimes it is close to the anus, it may be after a bowel movement. In the case of drainage, the blood volume is sometimes less than that of hemorrhoids.Blood in the stool caused by such intestinal polyps is very light in color, sometimes pink, but blood from hemorrhoids is fresh blood, which can be a lot. Colon cancer blood in the stool is mixed.
Question: Who are the high-risk groups for intestinal polyps?
Answer: People at high risk of colorectal polyps
1. Family members who have colon cancer or colon polyps
2. Long-term living in polyps-prone areas, such as Shanghai
3. Long-term westernized diet (high fat, high animal protein, low fiber, etc.), fried food
4. Age greater than 50
5. There are related diseases, such as liver cirrhosis, breast cancer, etc.
Question: Once you feel that you should be a high-risk group of colorectal polyps and want to go to the hospital for an examination, what is the importance of the examination?
Answer: Because most colon polyps have no symptoms. Once symptoms appear, most of them are large polyps or polyps that have become cancerous. Therefore, early examination is particularly important. Early examination can clearly determine how large the polyp is and how far it has developed. Cut off this polyp in time, and the incidence of colorectal cancer is significantly reduced compared with the normal population after the cut, which can reduce 70%-90%.
Question: How can you check whether there are colorectal polyps in your body?
Answer: It is mainly colonoscopy.
Question: What are the current treatment methods for intestinal polyps?
Answer: 1. Colonoscopy can be used for both examination and treatment. The advantage of colonoscopy is that it can clearly see the size of polyps.
2. The method of electrocutting and electrocoagulation is to burn the polyp, and this electrocoagulation is relatively safe, it can stop bleeding.
3. Surgical resection, such as familial adenomatous polyposis.
