A total gastrointestinal tract imaging is an examination of the entire gastrointestinal tract, including the esophagus, stomach, and intestines, and all of these parts are examined together. There are more precautions to take when performing a total GI test that patients should be aware of. You should not take any medications that can affect the imaging within a few days before the imaging, and you need to control them strictly. Gastric lavage is also required the day before the imaging to drain the digestive tract of debris so that the examination can be performed in a clean space. While ordinary X-ray examinations do not provide a detailed and specific picture of the digestive tract, total gastrointestinal tract imaging can completely reveal the shape of the digestive tract and the condition of the lesions that occur, which can be of great help in the treatment of patients. This is why total GI imaging is now widely used for the examination of digestive tract diseases.
