The ileocecal area is often involved by inflammatory bowel diseases such as tuberculosis, Crohn's disease, ulcerative colitis and so on. It is interesting how the villous form of the ileocecal border is transformed in these conditions. The villous form of the ileocecal border was examined by means of dissecting microscope. In this paper normal villous form of the ileocecal border is mentioned. Biopsy cases (41 cases), reseced cases (14 cases), and necropsy cases (38 cases) have been studied. Normal villous form is classified into three categories. 1, finger-shaped villi, 2, leaf-shaped villi, 3, ridge-shaped villi. In the ileocecal area, finger-shaped villi are transformed into leaf-shaped villi, next into ridge-shaped villi, and Gastroenterological Endoscopy finally into the colon mucosa. The ileocecal border is on the top of Bauhin's valve or slightly on the anal site of it. The dissecting microscope appearances of nonspecific ulcer and Crohn's disease are demonstrated in figure 6 and 7. These changes of the villous form are easily observed using magnifying colonoscope which has recently developed. More study about abnormal villous form is required.
