Recently colorectal cancer has been increasing in Japan. Therefore, the early detection of this disease is necessary. A newly designed colonofiberscope, type CF-PM, with 8.8mm in outer diameter, was applied to 212 subjects. Before colonoscopy, all subjects were forced to evacuate the bowles with glycerin enema without laxatives and limitation of diet. The rectum and sigmoid colon were visualized clearly in all subjects and even all parts of the descending colon were observed in 80 percent of them. It took about 4.6 minutes to examine one case in this study. During the examination 92 percent of the subjects complained of no pain or slight pain. It is emphasized that the pain by the newly designed CF-PM was much less than by the conventional sigmoidof iberscope. Because the “left colon” where there are over 70 percent of colorectal cancer was observed surely in a short time without pain or with slight pain by CF-PM, CF-PM is very useful for the screening of colorectal cancer.
