[Crohn's disease of the colon. History].

During the 18th, 19th, and at the beginning of the 20th century, various observations of inflammatory lesions of the colon and small intestine were published, which were different of tuberculosis to which was at that time attributed every chronical small intestinal inflammatory disease. It was only in 1932, that in a very important paper, Crohn, Ginsburg and Oppenheimer defined the terminal ileitis, afterwards called regional enteritis, and finally more simply Crohn's disease. Twenty years later, in 1952, Crohn's disease of the colon, confused until that date with colonic tuberculosis and with ulcerative colitis, was also identified as a separate entity. Since that time, the number of reported cases has tremendously increased through its is impossible to state whether the incidence of the disease has really increased or whether the diagnosis is done earlier and more precisely. Even today, the exacts limits of the disease are difficult to precise, since the causal agent of the disease is unknown, and that no biological test is completely secure. The present work reports 60 observations of chronic colitis, associated or not with small intestinal inflammation.
