抄録

With cooperation of Olympus co. we designed and developed a retrograde ileofiberscope consisting of the mother scope and the baby scope. The mother scope to be inserted into Bauhin's valve has the working length 1, 865mm, tip diameter 16mm and a large channel, 5mm in diameter. The baby scope is a direct viewing type with 80°in the angle of view field, 2, 520mm in total length, 4.5mm in diameter of the flexible part, and 3 to 50 mm in depth of observation. The angles of up and down irk the baby scope are both 1500. The baby scope can be inserted 300mm in maximal length further from the mother scope. After introducing the tip of mother scope in the terminal ileum, the baby scope is inserted to the ileum through the forceps opening of mother scope by manipulating the knob of up-down angle of baby scope and by rolling the mother scope. We can well observe the ileal mucosa in a satisfactory extent through the baby scope. This scope seems very useful in detecting the ileal lesion and for the accurate diagnosis. Furthermore this can be applicable to endoscopic observation of the fistula or stenosis of colonic diseases.
