| [ Summary ] |
A beginning endoscopist performed colonoscopies in 72 cases using a colonoscope with a flexible, adjustable shaft(CF-Q 240 Al) and 32 cases using the usual CF-Q240I. In comparison with the CF-Q240I, the CF-Q 240 Al has additional functions, by which the stiffness of the shaft can be adjusted by rotating a ring in the handle. The successful rate for insertion into the cecum, using CF-Q 240 I was 93.8%. The other hand, that for the CF-Q 240 Al was 100%, although it was 92% when using the only softer mode with the CF-Q 240 Al. The remaining 8% required the harder mode with the CF-Q 240 Al, to pass the splenic flexure. The insertion time for the CF-Q 240 Al was slightly longer than that for the CF-Q 240 I. However, the rate of these which were painless with the CF-Q 240 Al was higher than with the CF-Q 240 I. For beginning to intermediate level endoscopists the softer mode during insertion is recommended. The harder mode should be used after straightening the scope, when the scope makes a re-loop. The CF-Q 240 Al is useful, not only for expert endoscopists but also beginners. |
