Gastrointestinal polyps are raised lesions originating from the epithelial cells of the GI mucosa that project into the GI tract and are a common disease in gastroenterology. The incidence of GI polyps is related to geographical location, living habits, age, etc. For example, the older the age, the higher the incidence, the higher the incidence in western developed countries, and the lower the incidence in developing countries in Africa. When this disease occurs, it can easily cause bleeding and perforation of the digestive tract, and in serious cases, cancer can occur. Gastrointestinal polyps are pathologically divided into two types: hyperplastic and adenomatous, the latter being prone to cancer, with a cancer rate of 5%-40%, and adenomatous polyps are now recognized as precancerous at home and abroad. Most of the polyps in the gastrointestinal tract are insidious (the following is an example of colorectal polyps) and can be clinically asymptomatic. Some larger polyps can cause intestinal symptoms, mainly change in stool habit, increase in frequency, mucus or mucus blood in stool, occasional abdominal pain, very few have masses coming out from the anus during stool, some patients may have long-term blood in stool or anemia, and patients with family history often have a suggestive effect on the diagnosis of polyps. Some typical extra-intestinal symptoms often suggest the possibility of polyposis, and some patients often visit the doctor with extra-intestinal symptoms, which should not be ignored. For example, the presence of multiple osteomas and soft tissue tumors should be considered as Gardner syndrome, and the presence of skin mucosal pigmentation should be considered as P-J syndrome. It has been suggested that patients with suspected polyposis, even if there is no family history of polyposis, should be routinely examined by colonoscopy to exclude the possibility of the syndrome. Since gastrointestinal polyps are often clinically asymptomatic and easily overlooked, the medical profession now recommends that patients over 40 years of age should receive annual anoscopy and fecal occult blood examination; while those over 50 years of age should receive gastroscopy every 3-5 years for early detection and early treatment. Endoscopic resection is the preferred method for the treatment of gastrointestinal polyps, mainly including high-frequency electrocoagulation, laser and microwave cauterization, nylon wire ligation and argon ion coagulation. At present, our hospital mainly carries out high-frequency electrocoagulation resection method, which has the advantages of thorough treatment, simplicity, less damage, safety, less pain, wide application and easy to promote, and has become the most common and mature treatment method, usually 1-3 weeks after polyp removal, the wound healing. In conclusion, there are benign and malignant polyps, but most of them have no clinical symptoms, so preventive examination is very important. Therefore, we should remind you to have regular anal finger examination, fecal occult blood examination, and regular gastroscopy to detect GI polyps early and to distinguish benign and malignant by pathological section, which is good as a reference whether to remove them surgically. And adenomatous polyps are prone to recurrence after removal, so we should pay high attention to regular endoscopy to keep away from cancer!
