Generally, endoscopic removal of gastric polyps takes less than an hour to perform, but the exact time varies depending on the patient’s condition as well as the surgeon’s level of competence. Endoscopic removal of gastric polyps is not a very large operation and can usually be completed in less than an hour, but the exact time will depend on the doctor’s level of operation and the patient’s condition. Gastric polyps are a relatively common gastric lesion, and their occurrence is related to the patient’s diet, genetics, and so on. Since gastric polyps have the potential for malignancy, early treatment is usually recommended, and smaller gastric polyps can be removed endoscopically. Patients may experience black stools after polypectomy, which is related to bleeding during the procedure and is not a cause for concern. However, if patients experience bloody stools, vomiting blood, dizziness, etc., it is still important to seek medical attention as soon as possible to avoid worsening of the situation.
