Benign gastric ulcers: diagnosis and follow-up with double-contrast radiography.

Abstract

Double-contrast upper gastrointestinal examinations revealed 108 gastric ulcers at the authors' hospital during a recent 1-year period. With use of current double-contrast examination criteria for differentiating benign and malignant ulcers, the radiographic appearance was unequivocally benign in 68 patients, probably benign in 25, probably malignant in 12, and unequivocally malignant in three. Fifty-six patients with benign, probably benign, or probably malignant ulcers underwent endoscopy and biopsy. All 56 had benign ulcers. Another three patients with unequivocally malignant ulcers had endoscopically proved carcinomas. Thus, most suspicious ulcers were benign, but no benign-appearing ulcers were malignant. Follow-up double-contrast studies for 87 ulcers revealed complete ulcer healing in 68 (78%). A residual ulcer scar was observed in 61 of those 68 cases (90%). This experience suggests that double-contrast radiography is a valuable technique for diagnosing benign gastric ulcers and that once diagnosed, typically benign ulcers can be followed up radiographically until completely healed, without need for endoscopic intervention.
