Xiao Zhang was diagnosed with gastritis, gastric prolapse, and gastroesophageal reflux, and he needed to drink "milk" during the examination. Gastroenterography.
Recently, my friend Xiao Zhang always shouted about stomach pain, stomach distention, acid reflux belching, when he went to the hospital to see a doctor, the doctor asked him to do an upper gastrointestinal angiography examination, and finally diagnosed gastritis, gastric prolapse, gastroesophageal reflux, the doctor prescribed relevant drugs to Xiao Zhang, Xiao Zhang went home and described the examination process with his mother, saying that while drinking "milk", while doing the examination, his mother was very puzzled.
So what is a gastroenterography?
What is that white glass of "milk"?
What is an upper gastrointestinal angiography?
Upper gastrointestinal angiography is a common examination method for diagnosing digestive tract diseases, and its examination scope includes esophageal, gastric, duodenal and an unlimited range of small intestine and pharyngeography. Because there is little difference in the density of the upper gastrointestinal tract and the surrounding tissues, there is a lack of natural contrast, so barium sulfate or iodine contrast agent is required to develop the contrast. Upper gastrointestinal angiography is mainly used to observe the contours, mucous membranes, peristaltic state, dilation, patency, etc. of the esophagus, stomach and duodenum. That glass of white is not "milk"?During the examination, the doctor will ask you to drink a glass of white yogurt-like liquid, which is a contrast agent, which is used to show the upper gastrointestinal tract on X-rays, and barium sulfate is commonly used because it is insoluble in water and lipids, will not be digested and absorbed by the gastrointestinal tract, and will be excreted with the stool, so there is no need to worry.
Who can have an upper GI radiography?
Suspicion of gastrointestinal tumors, ulcers, inflammation, duodenal diverticulum, etc. , dysphagia, dysphagia. , to observe the relationship between periesophageal lesions and the esophagus. , portal hypertension, to know whether there are varicose veins. , suspicion of esophageal and gastric foreign body and inflammation. , esophageal, gastric, duodenal postoperative reexamination, esophageal, gastric, duodenal tumors and other lesions follow-up reexamination. , epigastric discomfort, bloating, weight loss, etc.
Who can't have an upper GI radiography?
Patients with extremely poor general constitution, cardiopulmonary failure and other serious conditions that cannot tolerate contrast agents. , acute peritonitis, severe ascites. , gastrointestinal perforation, intestinal obstruction, endoscopic biopsy within 24 hours of patients are prohibited from using barium sulfate. Barium sulfate is forbidden to be used for acute gastrointestinal bleeding, and barium sulfate can be used for examination after a negative fecal occult blood testIn special cases, nonionic iodinated contrast agents such as iohexol, iodophorol, and iodixanol may be used for testing. , pharyngeal paralysis, congenital esophageal atresia.
What do I need to prepare before the test?
Fasting and water (including any food, liquids) for 8-12 hours before the test. It is forbidden to use drugs that affect the function of the gastrointestinal tract and are opaque to X-rays for three days before the examination. , accumulation of gas in the colon, excessive stool, if necessary, take a dose of laxative or enema laxative on the night before the imaging.
What is the inspection process?Check the patient, ask for medical history, abdominal fluoroscopy, prepare barium or iodine contrast agent, inform the precautions for examination, oral gas production powder, upright, esophageal three-position filling image, mucosal image (anteroposterior, right anterior oblique position, left anterior oblique position), recumbent position, gastric level, right anterior oblique position, left anterior oblique position, prone position, right position, left anterior oblique position, semi-vertical right anterior oblique position, left anterior oblique position, etc.
What do I need to pay attention to after the examination?
Drink plenty of warm water to promote the excretion of contrast agent in the gastrointestinal tract. After an upper gastrointestinal angiography, eat light, easily digestible food.
