enterography

The small intestine was examined by X-ray examination. Basic Information Specialist classification: Digestive examination classification: X-ray Applicable gender: whether men and women apply fasting: fasting Tips: 1-2 days before the angiography, enter the slag and digestible food, and ban high-amount drugs. Fasting and water ban were started on the night before the inspection. 1-2 hours before the angiography, a 50% barium sulfate suspension was applied to an empty stomach of about 200-400 ml. Normal value 1. Gastrointestinal bleeding. 2. Unexplained abdominal pain and diarrhea. 3. Intestinal inflammation and tumors. 4. Small intestine adhesions. 5. X-ray examination, the bowel movement and abnormal position can be seen. Due to the displacement and compression of the small intestine in the tumor occupying site, it is often possible to change the organ inferring the tumor. Clinical significance Double contrast angiography is a very effective method for the diagnosis of small and medium lesions, especially for small concave lesions. Precautions 1, 1-2 days before the angiography into the slag easy to digest the food, and banned high atomic weight drugs. 2. Fasting and water banning began one night before the test. 3, 1-2 hours before the angiography, fasting 50% barium sulfate suspension about 200-400ml. Inspection process Barium angiography According to the scope of inspection can be divided into: 1 upper gastrointestinal angiography: including esophagus, stomach, duodenum and upper jejunum. 2 small intestine angiography: can be checked every 1 to 2 hours after upper gastrointestinal angiography, for empty, ileal and ileocecal examination. 3 colonography: divided into barium enema and oral barium angiography, the former is the basic method of examining the colon. According to the angiography method, it can be divided into the traditional sputum angiography method and the gas sputum double contrast method. 1 Traditional tincture contrast methods include: A. Mucosal method: A small amount of tincture is applied to show the morphology and structure of the mucosal folds, which is a mucosal image. B. Filling method: Apply more tinctures to fully fill the examined part, showing its contour, shape and peristaltic, etc., as a filling image. C. Pressurization method: appropriately press the receptor test site, push more barium agents to show some characteristics of the lesion, and be a pressurized image. 2 gas double contrast method: referred to as double contrast, it is the introduction of gas and tincture, so that the mucosal surface of the examined part is evenly coated with a layer of tincture, and the gas expands the lumen to show the fine structure of the mucosal surface and tiny abnormal. Small intestine fistula angiography: In order to check the small intestine, small intestine can also be used for angiography. The duodenal catheter was placed at the distal end of the duodenum, and a low concentration of tincture 500-600 ml was perfused for 5-6 minutes under fluoroscopy to observe the small intestine. Usually 20 to 30 minutes to reach the ileocecal area, more gas injection and anti-cholinergic drugs for low contrast double contrast angiography. Not suitable for the crowd Pregnant women, comatose. Adverse reactions and risks 1, may cause the small intestine to rupture. 2, may cause infection.
