title: Double-contrast examination of the oesophagus: the radiological changes of peptic oesophagitis.
abstract: A simple method for obtaining double-contrast views of the oesophagus as part of the routine double contrast examination of the upper gastrointestinal tract using high-density low-viscosity barium is described. The typical radiological changes of early peptic oesophagitis (confirmed by endoscopy) which can be readily demonstrated with this technique are illustrated as an example of its practical value. These consist of 'smudged' or 'cobble-stone' mucosa with thickened and distorted longitudinal folds. Superficial erosions and deep ulcers may also be seen. It is suggested that endoscopic confirmation of these characteristic radiological signs of peptic oesophagitis is unnecessary.
