Diagnosis of partial gastric diverticula.

Five partial (intramural) gastric diverticula were observed in about 10,000 routine examinations of the stomach and confirmed by endoscopy or operation. All diverticula were located on the greater curvature of the antrum. A round or oval pouch with a small neck and typical changes in shape and size represent the diagnostic radiographic features of partial diverticulum. Complete filling of the diverticulum by administration of a spasmolytic and the use of the double-contrast method proved to be important for the correct diagnosis.
