The diagnosis of duodenal ulcer become more easily because that is possible for observasion the doudenal bulb sufficiently after the development of duodenal fiberscopy. Untill now duodenal ulcer is diagnosed by radiography, the demonstration of the existense of the ulcer is undoubtful but the character of ulcer especially the decision of healing finding, in another words diagnosis of scar of the ulcer is not enough only by radiography. For precisely demonstration the finding of the duodenal ulcer, I collect 257 cases of active duodenal ulcer (63 cases in gastric mass survey and 194 cases in Nihon University Hospital). 336 cases of scar of duodenal ulcer (135 cases in gastric mass survey and 261 cases in the Nihon University Hospital) for 1, 970-1, 973. The conclusion will be illustrated as follow: 1. Scar of duodenal ulcer is two times more than active duodenal ulcer in gastric mass survey. 2. Scar of duodenal ulcer diagnosed by radiography is 62.9% in coincident with duodenal fiberscopic examination. 3. For the heightening of the diagnostic rate of scar in radiography it is better in pron, Fowler's position, 20°-40° right anterior. 4. Criteria for radiographic diagnosing a scar of duodenal ulcer: a) Convergency b) Difference of density c) Deformity d) Niche with blunt edge is easily disappeared by strong compression method 5. Scar stage was demonstrated at first time examination its recurrent rate is slightly higher than active duodenal ulcer but recurrent rate of asymptomatic duodenal ulcer is lower.
