In addition to gastroenteroscopy, gastrointestinal examination can also be performed by barium meal fluoroscopy of the upper gastrointestinal tract, ultrasound gastroscopy, and breath test.
1. Barium meal fluoroscopy of the upper gastrointestinal tract: It is a method of detecting gastrointestinal tract lesions by using barium sulfate as a contrast agent, which is swallowed and then examined under the contrast of X-rays. Barium meal fluoroscopy of the upper gastrointestinal tract cannot be performed on patients with cardiac, hepatic or renal insufficiency or intestinal obstruction.
2. Ultrasound gastroscopy: usually, a small ultrasound probe is put into the biopsy port at the endoscope to test the patient’s stomach and intestines, which can effectively detect whether the surface of the gastrointestinal mucosa of the patient is diseased and whether there are tumors and other conditions.
3. Breath test: generally refers to carbon 13 breath test and carbon 14 breath test, which can detect whether the patient’s stomach is infected with Helicobacter pylori.
In the examination of the stomach and intestines, the specific examination method should be carried out under the guidance of professional physicians.
