Summary
We developed a bi-plane TV monitoring system using a TV endoscope (Electronic endoscope
manufactured by Toshiba-Machida, Tokyo, Japan) that permits simultaneous display of
real-time and prerecorded images. Various findings of the two examinations can be
precisely compared using this system, and a detailed evaluation of the progress of
peptic ulcers obtained. In addition, the effects of various endoscopic therapies can
be accurately evaluated. In endoscopic injection sclerotherapy of esophageal varices,
now varices (or recurrent varices) were differentiated. In laser therapy for early
gastric cancer, precise delimitation of the lesion for radiation was possible, and
the therapeutic effects were more accurately evaluated. These results show the diagnostic
as well as therapeutic usefulness of this system. Furthermore, for the examination
of the lower digestive tract, X-ray images were incorporated into this system. This
is a useful modality for diagnostic and therapeutic procedures in colonic disease.
