  • Title: [Risks in roentgen study of the esophagus].
    Author: Vogel H.
    Journal: Rontgenblatter; 1986 Nov; 39(11):316-9. PubMed ID: 3809914.
    Abstract:
    X-ray examination of the oesophagus can lead to contact between the contrast medium and the lungs, connective tissue in the throat, and the mediastinum, pleura and peritoneum. The hyperosmolar iodine-containing contrast media used so far produce short-term displacement of liquid and local irritation. Long-term changes have not been reported. Contrast media containing barium sulphate will hardly produce irritation but may lead to chronic foreign body irritation; they should not be used if they are likely to come into contact with the pleura and peritoneum. Both water-soluble iodine-containing contrast media and barium sulphate-containing contrast media have resulted in deaths due to pulmonary inundation. In case of suspected disturbance of swallowing or perforation, a water-soluble contrast medium should be used at first. If there are no abnormal conditions, examination can be continued with barium sulphate contrast media. The new isoosmolar water-soluble contrast media offer interesting possibilities of detail improvement. Their better tolerance with satisfactory imaging properties should be established by animal experiments and by clinical tests.
