Abstract
Two hundred fifteen cases with 310 gastric ulcers of the posterior wall of the body, the en face view of which could be clearly visualized by the double contrast technique, were clinically and radiologically analyzed to define the features of those that were difficult to heal and those that tended to recur. The following results were obtained :
1. The features of gastric ulcer in the aged were occasionally noted in ulcers on the posterior wall of the body in patients in their 50s.
2. Healing was confirmed within 8 weeks in ulcers less than 1.0 cm in size or in shallow spindle-shaped ulcers, but healing was obviously delayed in ulcers with (1) irregular ulcer margin, (2) a further deep part in the ulcer bottom, (3) surronding elevative or non-elevative stiffness and (4) a few mucosal folds not converging toward the center of the ulcer and interrupted near the ulcer margin.
3. The manner of ulcer reduction was radiologically divided into concentric type and eccentric type. Eccentric reduction is the sign of delayed healing.
4. Recurrence was often encountered in ulcers more than 3.0cm in size, in those at the upper part of the body and in those with a further deep part in the ulcer bottom or surronding elevative or non-elevative stiffness. These abnormalities in the ulcer bottom or around the ulcer crater were also occasionally seen at recurrence.
5. Radiological analysis suggested that healing of ulcers of the posterior wall of the body is delayed in about 10% of cases and is possibly delayed in about 25%. Approximately 14-35% of ulcers detected at routine X-ray examination were considered to be recurrent.
