Crohn's disease, non-specific ulcers of the small intestine, and idiopathic proctocolitis in a Japanese university hospital from 1954 to 1974.
Most of the cases of Crohn's disease reported in Japan were originally treated surgically as acute appendicitis and, after appendectomy, they were diagnosed as acute terminal ileitis or acute Crohn's disease, which should belong to a category different from typical Crohn's disease, according to the international nomenclature by the Council for International Organization of Medical Sciences in 1973. Reviewing our university hospital records from 1954 to 1974, the incidence of typical Crohn's disease and idiopathic proctocolitis has been increasing, while the patients with intestinal tuberculosis have been decreasing. Clinical and histopathological features of operated three groups of our patients with Crohn's disease of the small intestine, non-specific ulcers of the small intestine and prestomal ileitis were comparatively studied. Furthermore, 9 cases of operated Crohn's disease of the colon and 23 cases of operated idiopathic proctocolitis were similarly evaluated. The importance of diagnosing Crohn's disease as a whole from both clinical and histopathological stand points of view was emphasized, and main differential diagnostic criteria between Crohn's disease and idiopathic proctocolitis were discussed.
