Introduction
Gastrointestinal barium meal examination usually refers to the examination of the stomach and intestines using barium contrast, which creates a clear contrast between the gastrointestinal tract and surrounding organs. During the examination, the patient first orally ingests the contrast agent and rests for about ten minutes. Then, specialized equipment is used to observe the distribution of the contrast agent, providing essential information for diagnosis and subsequent treatment.
Gastrointestinal barium meal examination usually refers to a radiographic examination of the stomach and intestines, typically using a contrast agent to create a clear contrast between the gastrointestinal tract and surrounding organs.
The gastrointestinal barium meal helps determine whether gastrointestinal diseases such as tumors, intestinal adhesions, or ulcers are present. During the examination, the patient first orally ingests the contrast agent and rests for approximately ten minutes. Then, specialized equipment is used to observe the distribution of the contrast agent—utilizing the principle that the contrast agent blocks X-rays—allowing clear visualization under X-ray imaging of the contrast between the agent and surrounding tissues, thereby providing essential information for diagnosis and subsequent treatment.
The ingested contrast agent is generally excreted from the body with feces and does not cause side effects. However, patients who already have conditions such as small intestine cancer or colon cancer may experience diarrhea after the examination.
