gastric barium meal angiography

X-ray examination of the stomach is mainly based on double contrast angiography, and a comprehensive examination program of mucosal method, filling method and compression method is beneficial to find lesions and improve the diagnosis rate. Normal stomach cramps meal: 1, the upper lens: supine position, the stomach is filled with filling phase, the stomach body is mucosal phase, the anterior pyloric pyloric part of the gas contains gas, the stomach wall is very clear, the gastric antrum is dilated. 2, the lower lens: the supine position of the gastric antrum is contracted, the fundus is still filled, the stomach is mucosal. The large curved mucosa of the stomach is serrated and is normal. The duodenal bulb is triangular and the descending portion is not fully filled. Basic Information Specialist classification: Digestive examination classification: X-ray Applicable gender: whether men and women apply fasting: fasting Tips: High-density drugs such as iodine, bismuth, and iron are prohibited for 3 days before angiography. Normal value Normal stomach cramps: 1. The upper lens is in the supine position, the fundus is filled with filling phase, the stomach body is mucous membrane phase, the anterior pyloric pyloric part contains gas, the stomach wall is very clear, and the gastric antrum is in a diastolic state. 2. The lower antrum of the lower antrum is in a contracted state, the fundus is still filled, and the stomach is mucosal. The large curved mucosa of the stomach is serrated and is normal. The duodenal bulb is triangular and the descending portion is not fully filled. Clinical significance Abnormal results: 1. The dual contrast method of the stomach can clearly show the fine structure of the surface of the gastric mucosa, such as the stomach area, which is valuable for the diagnosis of early gastric cancer and microscopic lesions. 2. Double contrast angiography can show the microscopic changes of the mucosal surface, which is of great value for the diagnosis of early gastric cancer. The lesions above 2cm are easy to find, and the fine X-ray examination based on double contrast angiography can be found within 1cm. Small gastric cancer, even tiny gastric cancer within 5mm. Need to check the crowd: 1. Upper abdominal discomfort and upper abdominal mass. 2. Congenital gastrointestinal abnormalities. 3. Review after stomach surgery. Precautions Taboo before inspection: 1. Ask the clinician to open an examination application form and contrast medication (barium sulfate, etc.). 2. Eat easily digestible foods before the day of angiography. Fasting before the angiography, no water for more than 6 hours, the stomach is empty. 3, 3 days before the angiography, high-density drugs are prohibited, such as: iodine, strontium, iron and so on. Requirements for examination: X-ray examination of the stomach is mainly based on double contrast angiography, and a comprehensive examination program of mucosal method, filling method and compression method is helpful for finding lesions and improving the diagnosis rate. So please pay attention to the doctor. Inspection process The sputum or sputum enema examination can only see the outline of the digestive tract, and the digestive tract angiography filled with tincture often masks the tiny lesions. Therefore, the oral foaming agent is often used or injected into the intestinal tract, so that the gastrointestinal tract has a high density. The tincture, and low-density air shadow, form a contrast contrast angiography, easy to get a positive result. According to the needs of clinical diagnosis and treatment, gastrointestinal barium meal angiography can be divided into upper digestive tract barium meal, full digestive tract barium meal, colon barium enema and small intestine barium enema examination. Not suitable for the crowd Inappropriate people: patients with acute respiratory infections, patients with severe heart, liver and kidney dysfunction, and patients with positive iodine test are generally not suitable for this test. Adverse reactions and risks 1, may cause infection. 2, may cause perforation of the gastrointestinal tract.
