Abstract
In colonoscopic findings of ulcerative colitis, frequently, there is a discrepancy between ordinary observations and histological findings: some of the cases, which were considered to be in quiescent stage by the former, were revealed to be in active stage by the latter. To dissolve the discrepancy we used the magnifying colonoscope. The 15 cases, which were diagnosed in quiescent stage by ordinary odservations, were checked. According to the shape and the arrangement of the orf ice of Lieberktln's gland, we classified the cases into 4 grades from 0 to III and compared them with the histological findings and the clinical course. As a result, the classifcation correlate to the histological findings and the duration of the quiescent stage in grade 0 and I is longer than that in grade II and III. Therefore, the use of magnifying colonoscope is effective for clinical judgement of the recovery to some extent. At present, it could not be a better method than biopsy because it is impossible to observe the total lesion by magnifying colonoscopy. However, it cotld be more effective in the near future, if we would be able to get the useful findings in judging the prognosis.
