Ten years have passed since the development of a push type enteroscope (SIF-B), and its usefulness has been sufficiently established. However, its specifications have become out of date. A newly devised enteroscope (SIF-10) has stronger angle mechanism, wider view field, and higher resolution compared with SIF-B. We had an opportunity to use SIF-10 in 20 patients. The results showed slight improvement in depth of insertion and time required for examination, proving the superiority of SIF-10 to SIF-B. However, the improvement in insertion was not marked, despite the remarkable mechanincal improvement in SIF-10. These facts suggested the limitation of push method itself and further modification was considered necessary.
