  • Look Inside

 Most important problem for considering the qualitative diagnosis of gastric ulcer seems to be gradual changes in the nature of gastric ulcer and of early cancer in the resected stomachs year by year. Based upon histological examinations and statistical results of the resected stomachs during these 20 years at Yokoyama's Hospital, the changes were summarized in the cases of gastric ulcer as decrease in relative frequency of chronic type and in acute and subacute type and in the cases of early gastric cancer as decrease in relative frequency of Type III (excavated or ulcerated type) and increase in Type II c (eroded type).

 Reappraisal of type III early gastric cancer for its macroscopic diagnosis in 316 cases thus far obtained shows that 65 cases (20.3 per cent) were recorded simply as gastric ulcer. On the other hand, of 6,023 cases of macroscopically diagnosed gastric ulcer, histologic study confirmed in 65 cases (1.1 per cent) cancer around ulcer. Reexamination of their gross pictures indicates the existence of abnormal findings, although slight, around ulcer in 20 cases, where cancer should have been suspected from the outset.

 On the basis of the above-mentioned results, we have referred to the utmost limits of diagnosis in gastric ulcer as well as to those problems that remain to be solved.
