    Abstract:
    OBJECTIVES: To evaluate the respective diagnostic value of flexible rectosigmoidoscopy and colonoscopy in the cytomegalovirus colitis. METHODS: Twenty-four patients with AIDS were studied retrospectively. The entry criteria were: flexible rectosigmoidoscopy or colonoscopy, with 2 rectal and 2 caecal biopsies, presenting cytomegalovirus inclusions bodies linked to an inflammation at least on one colonic biopsy. RESULTS: Twenty-four patients had 29 colonoscopies. In 16 cases colonoscopy was performed to the caecum. The endoscopic findings of the 16 full colonoscopies were: 7 right colitis, 5 diffuse colitis, 2 bisegmentary colitis, 1 proctitis and 1 non endoscopic lesion. The histologic findings of the 16 full colonoscopies were: 5 cytomegalovirus inclusions on rectal biopsies and 16 on caecal biopsies. For the 13 incomplete colonoscopies, 11 had inclusions on rectal biopsies. So the flexible rectosigmoidoscopy was not sufficient to find inclusions 13 times out of 29. CONCLUSION: Our study indicates that in the cytomegalovirus colitis, inclusions predominate in the caecum, isolated right colitis exists and extra-colonic cytomegalovirus disease is not always found. For these reasons full colonoscopy is necessary for diagnosis in patients with normal flexible rectosigmoidoscopy.
