  • Title: Pyloric channel ulcers and the air-contrast examination.
    Author: Wills JS.
    Journal: Radiology; 1979 Jan; 130(1):250-2. PubMed ID: 758662.
    Abstract:
    Three patients with pyloric channel ulcers presenting a diagnostic challenge on double-contrast gastrography are reported. These ulcers might have been overlooked had not films of the pyloric region been obtained when the ulcer was filled with barium. The air contrast examination of the distal stomach should be supplemented by the components of the conventional examination likely to show a pyloric channel ulcer as a barium-filled crater.
