 Eighty patients with ulcerative colitis underwent total colonoscopy, and several tiny aphthoid erosions were inspected at the terminal ileum in 26 cases (32.5%). The erosions were arranged scatterdly and quite different from the so called backwash ileitis. Histological findings showed mild or moderate infiltration of inflammatory cells in the mucosa of the terminal ileum, but no specific changes.

 To clarify the clinical meaning of these erosions, backgrounds of the patients with or without erosions were compared; sex, age at the onset and time of examination, suffering periods, clinical course, site of lesion, and so on. However, no characteristic differences were detected in the two groups. Erosions were detected in 20% of the patients even in the initial attack, and also 33.3% of the patients had suffered these lesions for over 15 years. These lesions were revealed in the remission phase and in the proctitis type. More over, erosions healed in 84.0% of the cases without any treatment within four months.

 Although ulcerative colitis is idiopathic, and the terminal ileum has generally received little attention, the involvement of the terminal ileum is not rare. We must pay much more attention to these lesions to clarify the pathogenesis of ulcerative colitis.
