Gastric ulcer scars.

Gastric ulcer scars, which imply previous peptic ulcer disease, are visible with moderate frequency during double-contrast examinations. This article investigates the radiographic appearance of gastric ulcer scars and the frequency of their occurrence in two differing patient populations. Results with 35 gastric ulcers that were followed to healing indicate that most ulcer scars appear as folds converging toward the ulcer site, at times accompanied by a central depression and/or gross deformity of the stomach. Two series of 200 patients each who underwent double-contrast examinations suggest a 1 to 4% incidence of ulcer scars, dependent upon the population examined.
