Abstract:
1. An endoscopic inspection method with a high-power observation optical system comprising: mucus eliminating and staining step for penetrating a staining fluid supplied through a channel into a gap between a distal end surface and a tissue surface to eliminate a mucus on the tissue surface while maintaining the distal end surface of a distal end portion of an endoscope having a distal end opening of the channel and a first lens which forms a super high-power observation optical system in contact with the tissue surface of an observation subject region, and staining the tissue having the mucus eliminated with the staining fluid; and super magnified observation step for performing a magnified observation at a cellular level by bringing the first lens which forms the super high-power observation optical system at the distal end portion into contact with the tissue surface which has been stained with the staining fluid.
