X-ray barium meal and barium enema examination purpose is what

X-ray barium meal examination mainly includes the detection of lesion location and size, evaluation of lesion depth, evaluation of gastric emptying function, etc., while barium enema examination includes the diagnosis of organic intestinal lesions, evaluation of intestinal motor function, screening of colorectal precancerous lesions, etc. 1, X-ray barium meal 1, detect the lesion site and size By observing the flow of barium agent in the digestive tract, you can understand the lesion site and size, and provide a basis for formulating a treatment program.2, assess the depth of the lesion Observing the passage of barium agent in the digestive tract, you can assess the depth of the lesion and judge whether the lesion invades the digestive tract wall or surrounding tissues. 3. evaluation of gastric emptying function By observing the emptying of barium in the stomach, we can evaluate the gastric emptying function and provide evidence for the diagnosis of gastroparesis. 2. Barium enema 1. Diagnosis of organic intestinal diseases Barium enema can observe the filling, defect and contour of barium in the colon, and can find organic diseases such as colon tumor, diverticulum, inflammation and stenosis, so as to make a clear diagnosis and staging. 2. evaluation of intestinal motor function Barium enema can observe intestinal peristalsis and emptying function, which is helpful in the diagnosis of intestinal motor disorders. 3. Screening for precancerous lesions of colorectal cancer For people at high risk of familial hereditary colorectal cancer, barium enema can be used as a screening method to assist in the diagnosis of colorectal cancer.
