ERCPにおけるファイバースコープの直線化について

抄録

Technique and merits of straighting the fiberscope within the stomach at ERCP was discussed in details. When duodenofiebrscope was reached to the papilla of Vater, the patient was moved from the left side position to the prone position, then fiberscope was withdrown gradually. By this method the body of the fiberscope within the stomach was straightened. After this procedure cannulation into the papilla of Vater was performed.This method has some advantages as follows. (1) The whole aspect of the pancreatic duct can be visualized without hindrance of the duodenoscope. (2) Cannulation in the prone position is convienient to get the pancreatic duct as a frontal figure without changing the patient's position. (3) Patient's torrelance is decreased with eliminating compression by the fiberscope to the greater curvature of the stomach. (4) Damage of the fiberscope by X ray exposure may be prevented at minimum because insertion length of the fiberscope is shortened.
