In the past 1 year, patients experienced abdominal pain after eating irritating foods, which were obvious under the xiphoid process, accompanied by black stools and no obvious mucus. After taking scopolamine or atropine, cimetidine or ranitidine, dilo granules and other drugs at home for 1 to 3 days at home, the above symptoms apparently eased to disappear, so no further examination was conducted. The patient had dizziness and tinnitus and other symptoms about 1 month before admission, but it did not work.
