title: Practical use of swan-type double-bending gastrofiberscope.
abstract: After devising remote-controlled angle to gastrofiberscope in 1964, the authors invented a swan-type double-bending gastrofiberscope in 1967. The double-bending gastrofiberscope does not require any change in a patient's position, for the motion of the tip is sufficient to observe every part of the stomach on supine position. In order to relax the patient both physically and mentally, relaxation of the patient is obtained by taking off this excessive attention on the endoscopic examination. Clear visual field can be obtained at the moment when the fiberscope passes the cardia, by stopping the scope just above the cardia and inflating sufficient air, and then, inserting the scope with the lens directed to the anterior wall of the greater curvature. Several marks are put on the body of the scope, as a functional scale, which makes its handling easier.
