Is the accuracy of esophageal barium meal fluoroscopy high?

summary

The gastric equivalent * retention fluid was characterized by hook shape, thickening of the gastric antrum mucosa, irregular filling defects and niche shadows on the lesser curvature of the antrum, irregular border, rigid gastric wall, interrupted mucous membrane, and peristalsis disappeared, showing a "cuff like" change. Esophageal barium meal fluoroscopy is used to observe the esophageal condition of patients after taking barium meal, which is used to detect esophageal diseases.

Is the accuracy of esophageal barium meal fluoroscopy high?

Barium meal examination included esophagus, stomach, duodenum, small intestine and right colon. After observing the esophagus in upright position, swallow the whole amount of barium. Observe the shape, contour, position, size, peristalsis and pyloric opening of each part of gastroduodenum in different postures. After the examination of stomach and duodenum, the small intestine, ileocecal part and colon should be examined at intervals according to the condition. In the process of fluoroscopy, spot films should be taken timely to keep records. The concentration of barium meal is 180-200% (w / V). It is suggested to go to a large hospital for esophageal barium meal fluoroscopy in time.

Barium meal is a kind of white rhombic crystal, which is used for gastrointestinal examination. Barium meal is medicinal barium sulfate (that is, barium sulfate suspension), so it is insoluble in water and lipid, so it will not be absorbed by gastrointestinal mucosa, so it is basically non-toxic to human. Barium meal examination, namely gastrointestinal barium radiography, refers to the examination method of using barium sulfate as contrast agent to show whether there are lesions in the digestive tract under X-ray irradiation. Different from barium enema, barium meal is a way of oral intake of contrast medium, which can be used for more clear radioactive examination of the whole digestive tract, especially the upper digestive tract.

The focus of esophageal X-ray barium meal examination is to find abnormalities and confirm lesions. The X-ray diagnosis of gastric cancer must be based on the X-ray manifestations of the tumor itself and its surrounding changes, combined with all the X-ray signs, clinical data and other examinations, in order to draw a correct conclusion. The results are as follows: (1) double contrast can clearly show the micro structure of gastric mucosa, such as gastric small area, which is very valuable for the diagnosis of early gastric cancer and micro lesions. (2) double contrast radiography can show the micro changes of the mucosal surface, which is of great value in the diagnosis of early gastric cancer. Lesions larger than 2 cm are easy to find, while fine X-ray examination based on double contrast radiography can find small gastric cancer within 1 cm or even within 5 mm. People who need to be examined: people with frequent gastrointestinal pain.

matters needing attention

Unsuitable crowd: pregnant women, children. General condition is very poor, severe failure. People with acute esophageal erosion injury. Check before taboo: check should be fasting, in the previous dinner suggest you eat some easy to digest food, check before 12 hours do not eat. When the esophageal retention is large, * try to extract it before angiography. The patients with cardiac spasm, hiatal hernia and tumor in the lower part of esophagus need fasting. It is not suitable to check immediately after eating, so as to avoid misdiagnosis caused by food residue adhering to the tube wall. Inspection requirements: check to relax and follow the doctor's instructions. Routine fluoroscopy of chest and abdomen was performed first.
