What is a contrast swallow?
For a contrast swallow, a patient drinks a contrast agent during an X-ray to visualise the transition from the oesophagus to the stomach.
A contrast swallow allows for the identification of a diaphragmatic hernia and the assessment of its size. In addition, problems relating to the passage through or the reflux of the contrast fluid in the oesophagus can also be identified. The length of the oesophagus can be measured as well, which is important when considering surgical treatment.
