Summary
40 patients were examined by peroral endoscopic ultrasonography with two new prototypes
(Prototype II and III, Olympus Optical Co., Tokyo, Japan). Indications were various
intestinal diseases. Topographical orientation was facilitated by standard positions
of the instrument. The organs identified included liver, gall bladder, common bile
duct, pancreas, spleen and kidneys. Pathological lesions of the organs mentioned were
characterized by the echo pattern known from external ultrasonography. At present
endoscopic ultrasonography is not a routine method but may provide additional information
to peroral endoscopy and external ultrasonography without replacing these methods.
