What is a gastric polyp? Gastric polyps are mushroom-like elevations of the mucous membrane of the stomach; they are more common and can be found in 1-3% of middle-aged and elderly people; they grow slowly; some polyps have a large base, some have a root with a tip; the surface can be lobed and patterned with a reddish color; they vary in size, from 1-2 mm for small ones to 2-3 cm for large ones; they can be single or multiple, and there can be up to hundreds of them. What are the consequences of gastric polyps? (1) Smaller polyps usually have no special symptoms; larger polyps may have upper abdominal discomfort, abdominal pain, abdominal distension, etc. Any unexplained upper abdominal discomfort for more than two weeks should be examined by gastroscopy. (2) When the polyp grows to a certain size, it may bleed, vomiting blood, tarry stool, shock may occur in serious cases, and examination may reveal positive occult blood in stool and anemia. (3) When a large polyp is blocked at the entrance to the cardia or the exit to the pylorus of the stomach, nausea and vomiting may occur. (4) Once the gastric polyp is found by gastroscopy, pathological section must be done, such as hyperplastic polyps are generally not cancerous, such as adenomatous polyps will have a certain percentage of cancer. Why do gastric polyps grow? The reason is not very clear, the most likely cause is still the long-term eating spicy raw and cold hard food, hungry and full, like to eat pickled products and other bad eating habits, drinking and smoking and other bad habits, H. pylori infection and other causes of chronic gastritis, on the basis of which polyps grow. In the past few years, there has been an increase in the number of cases of multiple small polyps in the fundus of the stomach due to the long-term use of proton pump acid suppressant omeprazole and other treatments. Familial adenomatous polyposis of the stomach is a less common cause. Should gastric polyps be treated? How to treat them? (1) A few millimeters of small polyps, especially multiple small polyps, can be removed with biopsy forceps during gastroscopy, or can be left untreated, but regular gastroscopy; larger polyps can be removed at an optional stage; polyps that bleed, are suspected or have cancer should be removed in time. (2) Minimally invasive resection under gastroscopy is now the preferred method, and the operation usually takes about 10-40 minutes. Depending on the size and shape of polyps, they are usually treated by endoscopic techniques such as thermal forceps or argon knife fracture, electrocoagulation trap removal, mucosal resection (EMR), and also by combined gastroscopic and laparoscopic treatment. (3) Multiple polyps may not all be removed at once and require multiple treatments; laparoscopic or caesarean surgery is appropriate for definite cancerous lesions, especially when there are suspicious lymph node enlargement on abdominal CT examination.
