The shortcut to mastering colonoscopy insertion technique is to practice on the colon model. It is like you can attain advanced driving techniques faster and better when you practice on the circuit than on the regular road. The colon model is the Formula-1 circuit of colonoscopy training. Training should start with understanding the characteristics of the scope and learning the skill to maneuver it with the actual scope on a bed. First, understand the basic theory of the Singular Method with your own fingers, thereafter learn with the colon model. If you practice one thousand times on the colon model until you can insert the scope fast enough, you can make up for the scarcity of actual cases.
