| [ Summary ] |
The shaft retention and shortening method that began with the "one-man" method for the insertion of the colonoscope evolved rapidly with the introduction of the magnifying endoscope in the 1990s. The shaft retention and shortening method is the insertion technique that does not allow the extension of the intestinal tract by maintaining the linearity of the axis of the scope, facilitating conduction of power to the scope tip, and pushing the scope forward by the shortest distance while creating an ideal intestinal axis. Therefore, it is important to have adequate knowledge and practice of the 3S insertion technique. Furthermore, it is important to understand the optimal distance of the scope, and utilize the assistants such as air control or the food enough. The cause of the premise not to put an excessive burden on the intestinal tract, we endoscopists must not always forget back to the basics. |
