intestinal polyps is a common diagnosis of in colonoscopy. Some people have a pathological report of tubular adenoma grade II after polyps are removed and they feel very scared. So what is the case with tubular adenoma ? Is it serious? What should I do?
First look at what intestinal polyps are
Intestinal polyps refer to the bulge-type growth that protrudes into the intestinal cavity due to excessive hyperplasia of the intestinal mucosa. The formation of intestinal polyps is mainly related to genetic factors. Bad living habits such as: love to eat red meat, insufficient dietary fiber intake, long-term constipation, and long-term chronic intestinal inflammation are also the causes of intestinal polyps. Intestinal polyps are divided into adenomatous polyps, proliferative polyps, inflammatory polyps and hamartomas according to their pathological types. Among them, adenomatous polyps are a common type of intestinal polyps, accounting for as high as 50% to 67%.
Adenomatous polyps are precancerous lesions of intestinal cancer
According to data research, more than 90% of intestinal cancers evolved from adenomatous polyps. Adenomatous polyps are like a time bomb. As time goes by, the chances of developing into bowel cancer will become greater and greater. From polyps to intestinal cancer, it generally goes through the process of: small adenomatous polyps → large adenomatous polyps → intestinal cancer. This process is a slow process, which usually takes 5 to 15 years. Therefore, don’t worry too much if you find adenomatous polyps in colonoscopy. Whether adenomatous polyps with
is related to factors such as the size and number of polyps. Generally speaking, the larger the polyps, the more likely they are to become cancerous. According to statistics, the cancer rate of polyps with a larger number of 2cm is as high as 50%, while those with more than 3 polyps have a cancer rate of 66.7%.
adenomatous polyps are divided into three types: tubular adenoma, villous adenoma and mixed adenoma. The carcinogenesis rate of villous adenoma is relatively high, while the carcinogenesis rate of tubular adenoma is relatively low.
Is the tubular adenoma grade II severe?
Tubular adenoma is divided into three levels according to the degree of differentiation of cells. The higher the degree of differentiation is level I, and the worse the degree of differentiation is level III. The differentiation is level II. Generally speaking, the higher the degree of cell differentiation, the closer it is to normal tissue cells, and the lower the degree of cell differentiation, the closer it is to cancer. If tubular adenoma is grade III, it can basically be considered as high-grade intraepithelial neoplasia, which is early intestinal cancer. Although the tubular adenoma grade II is still benign polyps, the possibility of cancer will greatly increase as the polyps grows. Therefore, if the intestinal polyps tubular adenoma grade II is found, it is necessary to pay enough attention to it and should be removed under endoscopy in a timely manner and should be reviewed regularly.
Regular reexamination of adenomatous polyps is important
Since the formation of intestinal polyps is related to genetic factors, eating habits, living habits and other factors, no matter how you prevent it, intestinal polyps may recur. It is reported that the recurrence rates of 1 to 5 years after intestinal polyps are 37%, 47%, 41%, 48% and 60% respectively. Therefore, after intestinal polyps removal, you must regularly check colonoscopy , and strive to achieve early detection and early resection.
Generally speaking, for pathological diagnosis of adenoma polyps, if it is a tubular adenoma, the number does not exceed 3, and the polyps are 10mm, the colonoscopy can be reviewed once a year, but if it is a villous adenoma or a tubular adenoma, the number of polyps exceeds 3 and the size exceeds 10mm, it is best to review the colonoscopy within half a year.
