Upper gastrointestinal X-ray barium meal

Upper gastrointestinal X-ray barium meal examination is one of the main methods for diagnosing upper gastrointestinal diseases, and complements fiber microscopy. Gastric and duodenal and hepatobiliary tract can cause duodenal gallbladder or common bile duct fistula and Oddi's sphincter insufficiency due to inflammation, ulceration, and tumor infiltration. Usually, the patient is fasted 8-12 hours before the examination, and the drinking water is forbidden 4 hours before the examination. Basic Information Specialist classification: Digestive examination classification: X-ray Applicable gender: whether men and women apply fasting: not fasting Tips: Usually the patient is fasted 8-12h before the test, and the drinking water is forbidden 4 hours before the test. Normal value 1. Upper abdominal discomfort and upper abdominal mass. 2. Congenital gastrointestinal abnormalities. 3. Review after duodenal surgery. Clinical significance Abnormal results: In the examination of barium meal, the direction of turbulence was abnormal, and the fistula showed that the liver and gallbladder were filling and developing. People who need to be examined: the stomach and duodenum and the liver and biliary tract can cause duodenal gallbladder or common bile duct fistula and Oddi's sphincter insufficiency due to inflammation, ulceration, and tumor infiltration. Precautions Contraindications before the examination: Usually the patient is fasted 8-12 hours before the examination, and the drinking water is forbidden 4 hours before the examination. Requirements for inspection: cooperate with the doctor. Inspection process X-ray barium meal examination, usually divided into three sections of esophagus, stomach and duodenum. Stomach examination: After oral administration of an imaging agent that is not absorbed or adsorbed by the gastric mucosa, it is discharged into the intestine by gastric peristalsis, and the gastric emptying time can be calculated from the decrease in radioactivity in the stomach to understand the motor function of the stomach. The developer is a solid or liquid test meal prepared from 99Tcm-SC or 99Tcm-DTPA. The subjects were fasted for 12 hours, and all the solid or liquid test meals were eaten within 5 minutes, and collected at a speed of 1 frame/5 min for 2 hours, and the food stomach half emptying time was calculated by ROI technique. Esophageal examination: The subject was fasted for more than 4 hours, and the mouth contained 99Tcm-SC37MBq (1mCi) of 15ml solution for rapid swallowing. The standing position was collected at a speed of 1 frame/0.5s for 60s, and then swallowed every 30s. A total of 5 min was collected. The total esophageal transit time and the passage time of each segment (upper, middle and lower) and the esophageal passage rate within 5 min were calculated by computer ROI technique. Duodenal examination: The subject is fasting for more than 4 hours. The examination method is the same as that of hepatobiliary. When the common bile duct and duodenum are developed, 300ml of milk is used to promote bile excretion. After every 10 minutes, it is collected from 1 to 60 minutes. The duodenogastric reflux index (DGRI) was calculated using ROI technique. Not suitable for the crowd Inappropriate crowd: There are no special instructions for people who respond to barium meal. Adverse reactions and risks Nothing.
