Gastric polyp surgery usually requires a hospital stay of about one week, which may vary on an individual basis. Gastric polyp surgery is a very mature and minor procedure that can be done endoscopically in many cases. However, the entire procedure including preoperative examination, surgery, and postoperative observation and treatment is generally recommended to be hospitalized for about one week. Before surgery, patients need to do blood routine, coagulation function, infectious disease, liver and kidney function tests, etc. The test results are okay before the surgery. The postoperative period will cause some damage to the body, and there is a risk of bleeding and infection. The amount of bleeding is usually small and only after reaching a certain amount will there be symptoms such as vomiting blood and black stool. Therefore, after the polyp surgery, patients need to be hospitalized for observation and treatment, pay attention to whether there is abdominal pain, vomiting blood, black stool, and be alert to the possibility of perforation to avoid serious situations. In addition, patients who have undergone gastric polyp surgery must follow the doctor’s instructions, be hospitalized for observation, pay attention to a light diet, quit smoking and drinking, pay attention to rest and avoid overexertion.
