Gastrografin Swallow

 

A Gastrografin Swallow shows an outline of the oesophagus and stomach on a plain X-Ray, using Gastrografin as a contrast medium which is swallowed by the patient. It may show irregularities of the usual smooth outline, caused by strictures (narrowing) or ulceration – damage to the mucosa (lining) of the oesophagus. It differs from a Barium Swallow in that the contrast material is water soluble and less irritating to body tissues if there is a leak from the oesophagus – known as a perforation.

How the Test is Performed

Having a Gastrografin Swallow test involves drinking some liquid which shows up on an X-Ray. This contrast medium is non-toxic, and shows up as white on a plain X-Ray taken during or soon after swallowing. The gastrografin shows up the inside of the oesophagus (food pipe) and gives an idea of its lining surface.

Medical Conditions and Symptoms

A Gastrografin Swallow may be requested by your doctor if you have difficulty swallowing (dysphagia) or painful swallowing (odynophagia). These symptoms may indicate a narrowing in the oesophagus (known as a stricture), ulceration or inflammation of the oesophagus (oesophagitis), or failure of normal relaxation of the oesophagus during swallowing (achalasia).

Test Results Explained

Gastrografin Swallow results are sent to your doctor after the images have been interpreted by the Radiologist. One of the above conditions may be diagnosed, or further tests may be required if the test is inconclusive.
