Popis:	In 1980, an endoscopic intubation method utilizing a long intestinal tube for ileus was developed. However, with this method the success rate of jejunal intubation was 89.4%, and the intubation time was 17.5±8.1 minutes (Mean±S. D.). These results were unsatisfactory as “rapid and reliable intubation” was the initial objective. Because the earliest guide wire was excessively elastic and therefore pliable, it formed a loop in the stomach. The guide wire was then improved by increasing its rigidity by approximately 20%. With this improvement, the force needed to advance the guide wire can now be effectively transmitted to its tip. As a result, the initial objective of improving the rate of jejunal intubation with the long tube (to 100%) and shortening the intubation time (to 8.9±3.9 min.) was achieved.
