Guideline/Practice Point : Gastrografin Swallow

Gastrografin Swallow

Surgical Principles


Gastrografin Swallow (X-Ray) Test

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. A gastrograffin swallow is performed following a roux En Y Gastric Bypass, Sleeve Gastrectomy and Duodenal Switch to  assess the integrity of the anastomosis looking for leakage.

This contrast medium is non-toxic, water-soluble and has an unpleasant taste.

This investigation may be used when a leak is suspected or as standard practice in some surgical units.
