Barium double contrast angiography

After the wide application of gas-spot double contrast angiography, the accuracy of barium meal examination for the diagnosis of gastric cancer has been significantly improved, and the discovery of early gastric cancer has also improved to a new level, and the diagnosis of gastric ulcer is also more accurate. It can also be applied to the examination of other diseases of the whole digestive tract. Basic Information Specialist classification: Digestive examination classification: X-ray Applicable gender: whether men and women apply fasting: fasting Tips: For 12 hours, the food must be fasted after 8:00 pm on the day before the inspection. Milk, soup, boiling water and other liquids, but you can eat dry food. Normal value 1. The intestines are filled continuously, evenly, with the same thickness and thickness. The movement is normal and the movement is normal. The diameter of the intestine is 4cm. 2. The bowel outline is smooth and soft. 3. The small intestine mucosa folds straight, at equal intervals, across the intestine at right angles. The jejunal folds are tightly spaced, the ileum is widely spaced, and the crease thickness is less than 2 mm. Clinical significance When the sputum is double contrast angiography, the stomach is in a state of relaxation and low tension, the peristalsis of the stomach wall is weakened, and the secretion of gastric juice is reduced, which is beneficial to the adhesion of the expectorant; the mucosa is more easily stretched, and the image is clearer, which is conducive to the discovery of smaller lesions. At present, although fiberoptic endoscopy has been widely used, barium meal examination is still a very important diagnostic method, especially the gas double contrast contrast method, which can complement the gastroscopy. Barium meal examination has unique advantages in determining the extent and size of the lesion, the relationship between the lesion and the whole stomach, and the compression of the stomach on the stomach wall. Indications: 1. Difficulty swallowing or discomfort. 2. Esophageal foreign body, rupture, perforation. 3. Identify the nature, location and extent of esophageal tumors. 4. Understand the presence or absence of esophageal varices in patients with portal hypertension. 5. Esophageal congenital diseases. 6. Understand the compression of the esophagus, such as mediastinal tumors and cardiovascular diseases. Precautions Forbidden before inspection: 12 hours of water ban, that is, after 8:00 pm on the day before the inspection, you must fast-eat milk, soup, boiling water, and other liquids, but you can eat dry food. It is forbidden to eat all food in the morning; take 50 ml of 50% magnesium sulfate solution for laxatives one night, drain the feces, and there is no residue. Requirements for examination: The clinician must be accompanied throughout the procedure to prevent the patient from being at risk. Inspection process 1. Sitting position, mouth opening device, inserting the small intestinal angiography catheter (Bilbao-Dotter tube) into the esophagus and stomach through the opener, and confirming that the catheter has entered the gastric cavity after the fluoroscopy, the patient is in the right lateral position, the transcatheter Introduce the guide wire, pay attention to the distal end of the guide wire can not go beyond the catheter head, and then the catheter is further sent down, when the catheter head to the gastric pylorus, if the catheter can not smoothly pass through the pylorus, the guide wire can be pulled out and a small amount of contrast agent is injected to make the pyloric tube open. Then take the catheter into the left side, and take the left lateral position. The gas in the stomach gathers in the antrum of the stomach to open the pyloric tube, and then enter the catheter into the duodenum. Note that the guide wire cannot enter the duodenum, so the guide wire should be pulled outward and the catheter should be forwarded until the catheter head is in the duodenum. 2. Exit the guide wire and fix the extracorporeal part of the catheter with adhesive plaster. 3. Take the left lateral position and uniformly inject 350~400ml 50W/V% tincture in 10~15 minutes. During the injection process, change the position according to the situation and take in the filling phase. 4. Inject the air into the terminal ileum, and take a double contrast film of the small intestine in time. 5, after the small inflated volume is appropriate (about 1000 ~ 1500ml, the mark is twisted intestinal mucosal folds straight), intravenous injection of low-drug 654-220mg. 6, pull out the small intestine catheter, swivel twice, and then supine position in the middle and lower parts of the abdomen. 7. Repeat the inspection and filming. Not suitable for the crowd Inappropriate people: those who are allergic to contrast agents and those with severe liver function. Adverse reactions and risks Nothing.
