Esophagography

X-ray examination can determine the upper and lower range of the tumor, and has certain reference value for treatment. Gastric double contrast angiography clearly shows the structure of the esophageal mucosa. X-ray examination can determine the upper and lower range of the tumor, especially double contrast angiography, which has certain reference value for treatment. To determine the extent of the disease, erosion around the esophagus, and lymph node metastasis and disease staging based on esophageal extensibility, CT examination must be relied upon. Basic Information Specialist classification: Digestive examination classification: X-ray Applicable gender: whether men and women apply fasting: fasting Reminder: Check on an empty stomach to prevent the presence of food or stagnation from affecting the examination and diagnosis. Normal value 1. Difficulty swallowing or discomfort. 2. Esophageal foreign body, rupture, perforation. 3. Identify the nature, location and extent of esophageal tumors. 4. Understand the presence or absence of esophageal varices in patients with portal hypertension. 5. Esophageal congenital diseases. 6. Understand the compression of the esophagus, such as mediastinal tumors and cardiovascular diseases. Clinical significance (1) X-ray examination can determine the upper and lower range of the tumor, especially double contrast angiography, which has certain reference value for treatment. To determine the extent of the disease, erosion around the esophagus, and lymph node metastasis and disease staging based on esophageal extensibility, CT examination must be relied upon. (2) The esophageal foreign body examination should first look at the neck and chest to observe whether there is a foreign matter that is impervious to X-rays, and then the cotton ball can be orally immersed in the tincture, such as when the cotton ball stays at a fixed position and does not fall. It should be suspected that there is a possibility of foreign matter. This method is effective for chicken bone or fish bone spur, but sometimes it has a false positive. It should be combined with the patient's medical history and esophagoscopy for final diagnosis. (3) Double contrast angiography of gas sputum can clearly show the structure of esophageal mucosa. Precautions In general, the patient does not need any preparation before the examination, but in the case of a fistula, esophageal hiatus or suspected esophageal tumor of the esophagus, it should be checked on an empty stomach to prevent the presence of food or retentate from affecting the examination and diagnosis. Inspection process X-ray examination. Not suitable for the crowd Fascinated group. Adverse reactions and risks May cause an infection.
