Colitis was found in 302 out of 5803 patients (5.2%) who underwent colonoscopy for the first time. Unclassified colitis (with slight edema, hemorrhage etc.) accounted for 89.1 % of these cases. Most of the colitis (93 cases, 40.1 %) was found to affect the sigmoid colon, followed, in order of decreasing frequency, by the rectum, cecum, transverse colon, descending colon and ascending colon. A comparison of the percentage revealed that of colitis found in two groups which were given different pre‐treatments, 80 out of 3280 cases (2.4%) were found among those examinees pre‐treated by the modified Brown method (B‐method), while 152 out of 2513 cases (6.0%) were found in those pre‐treated by the PEG oral lavage method (P‐ method). About 40% of the diagnosed colitis cases were free from symptoms (diarrhea, abdominal pain, etc.); the results of the guaiac test on their stool samples were negative. We hypothesized that, in these cases, signs of colitis were actually pretreatment‐induced artifacts. No significant differences were found among groups with regard to sex and age, nor was the fraction of colitis cases represented by artificial colitis significantly different between pre‐treatment groups.
