Gastric polyps are protruding papillary tissues on the surface of the gastric mucosa, which are often asymptomatic when small and are usually found incidentally during gastrointestinal barium meal imaging, gastroscopy, or surgery for other reasons. The name “polyp” usually only refers to a bulge observed with the naked eye. In clinical practice, it is very common for some people to be detected with gastric polyps during endoscopy, which makes them wonder whether gastric polyps are cancerous or not, and what kind of gastric polyps are susceptible to cancer? How to deal with gastric polyps? Therefore, they become very worried and have trouble sleeping and eating, thinking that they have an incurable disease. If polyps are found, it is recommended to take pathological tissue biopsy to characterize and guide the next step of treatment. Pathologic typing can be divided into adenomatous polyps and hyperplastic polyps. Adenomatous polyps are composed of densely arranged and crowded hyperplastic glands, with different degrees of atypical hyperplasia, and are precancerous, with a high cancer rate of 10%-30%; hyperplastic polyps, also known as regenerative polyps or inflammatory polyps, are arranged in a relatively disorganized manner, and are characterized by prolonged hyperplasia of the glands, with large gaps between the glands, and some of them are intermingled with immature Some of them have immature cells in the center. The majority of hyperplastic polyps do not have atypical hyperplasia, and the cancer rate is extremely low, only 0.4%. Generally, the size of gastric polyps is less than 1cm, and they are very small. Hyperplastic polyps are mostly benign lesions, but there are a few hyperplastic polyps that will cause indigestion, abdominal pain and discomfort when they grow up, as well as upper gastrointestinal bleeding, and they may also become cancerous. Although adenomatous polyps are prone to cancer, they can be prevented, such as abdominal discomfort, pain, nausea, loss of appetite or black stool and other symptoms, timely gastroscopy, early diagnosis and early treatment. When the diameter of polyps is larger than 2cm and wide base without clitoris; the growth rate is abnormally rapid; the pathological examination is adenomatous polyps with heterogeneous hyperplasia, suspected cancer and cancerous changes, we must be very vigilant. Although surgery brings a lot of risks and trauma, it is still necessary to remove these dangerous polyps when the tendency of cancer is determined. The indications for surgery are: (1) Non-tibial or broad-based polyps larger than 2 centimeters. (2) Progressively enlarging polyps. (3) Adenomatous polyps with heterogeneous hyperplasia, suspected cancer and carcinoma. Endoscopic resection is the first choice of gastric polyp treatment, mainly high-frequency electrocoagulation excision method, laser and microwave cauterization, nylon wire ligation method and argon ion coagulation method. Endoscopic treatment of polyps is simple, with little damage and low cost, most of them are one-time treatment, and a few of them need to be resected in several times. Regular follow-up through endoscopy can also detect recurrence of polyps and give timely treatment to prevent cancer. The overall prognosis of gastric polyps is good. As long as we pay attention to our diet, eat less junk food, work and rest on time, and keep a good mood, we can prevent gastric polyps from occurring.
