| [ Summary ] |
The large-diameter scope is very useful in the shaft retention and shortening method owing to the ease of achieving linearity of the axis. Furthermore, observation and treatment is also facilitated because the large-diameter scope has good conductivity of the delicate movement of the endoscopist's hand to the scope tip. In contrast, the small-diameter scope is useful in cases where performing the shaft retention and shortening method poses a challenge. This is because the small-diameter scope does not exert excessive pressure on the intestinal tract and can be inserted while forming a loop and stretching the tract. It is necessary for endoscopists to understand the characteristics of each scope thoroughly and make the appropriate choice depending on the case. |
