The barium gastrointestinal examination report includes the examination items, examination findings and diagnostic opinion. According to the examination site, the barium meal examination can be divided into esophageal examination, stomach and duodenum examination and small intestine examination. What is seen: The shape, outline, location, size, peristalsis and pylorus opening of the esophagus, stomach and duodenum as observed through the examination. Diagnostic opinion: Based on the diagnostic results given by the examination, common diagnostic hints include esophageal varices, esophageal cancer, gastric ulcer, duodenal ulcer, and gastric cancer. (1) No pathological X-ray signs are seen in the chest and abdomen; (2) The mucosal folds of the esophagus are coherent, and the barium passes smoothly throughout the esophagus without obvious obstruction or filling defect; the stomach has a small amount of retained fluid, the gastric mucosal folds are slightly thickened, the stomach is fishhook-shaped, with medium volume and position, and the peristaltic waves and tension are normal; (3) The pyloric duct is in the middle, and the barium passes smoothly; (4) The duodenal bulb fills well, and the mucosal folds are (5) The duodenal circle is not large, and the mucosa of the descending intestinal canal is regular. (2) Common diagnostic diseases (1) esophageal varices Early manifestations are slightly thickened or varicose mucosal folds, slightly serrated lumen edges, soft walls, and good passage of barium; typical symptoms in the progressive stage are bead-like or earthworm-like filling defects. After diagnosis, rubber band ligation or endoscopic treatment is required. (2) Esophageal cancer Early stage shows disorder, roughness or interruption of mucosal folds, small filling defect, stiffness of canal wall, interruption of peristalsis, irregular niche shadow, which needs to be further combined with CT, MRI and symptoms for comprehensive judgment. After the diagnosis is confirmed, surgery needs to be preferred, together with radiotherapy. (3) Gastric ulcer with prominent outward niche shadow and mucosal lines converging to the niche shadow. After the diagnosis, it is necessary to avoid the application of acid-forming agents and anticholinergic drugs, as well as to give gastric mucosa-protective drugs, such as aluminum thioglycollate and bismuth, under the guidance of doctors, and to actively treat H. pylori infection. (4) Duodenal ulcer The normal triangular shape of the duodenal bulb disappears and punctate niche shadow is seen, and in severe cases, triangular lobe type is seen. (Treatment is the same as that of gastric ulcer.) (5) Gastric cancer can be manifested as signs of gastric ulcer, with shrinkage of gastric lumen, irregular filling defect, stiffness, leather banding, complete disappearance of mucosa, and disappearance of peristalsis, which needs to be combined with CT, MRI and symptoms to make a comprehensive judgment. After diagnosis, surgery is needed, together with chemotherapy, targeted therapy and other supportive treatments.
