Abstract
11 patients of campylobacter colitis were examined endoscopically, histologically, and scanning electron microscopically. Five of them were children and six were adults. The findings in child patients were severe compared with that in adult patients. The inflammation was recognized on the ileum as well as colon in the former cases, while the observation in the latter cases showed acute colitis. In mild cases, glossy appearance due to edema and slight reddening were noted generally. In severe cases, roughening, dark reddening and erosions on mucosal membrance, mucous pooling, and/or dilation of the capillaries with bleeding from their peripheral parts were the general findings. The differenciation between this colitis and bacillary dysentery or ulcerative colitis was thought to be (extremely) difficult. Histologically, crypt abscesses were observed in six cases. Frequent occurence of this finding seemed to be characteristic for campylobacter colitis. Apparent changes were observed on the microvilli using scanning electron microscope, although this was not a specific finding.
