  • Abstract
  • Look Inside

 Authors reported the cytological results of early gastric cancer by the endoscopical method with fibergastroscope.

 In 1965, fibergastroscope for lavage cytology (K-type) was deviced in Japan and in 1966, the C-type of fibergastroscope was improved, which the distal part of the scope can be raised up or lower down in each 90 degree and be rotated right and left in each 45 degree with simple handle manipulation. By this instrument, any lesion in almost all parts of the inside of stomach can be performed the lavage cytology. The cytological result of lavage cytology for 35 cases of early gastric cancer with these instrument was 94.2% in positive rate. Authors compared with this result to the touch smear preparation method from biopsy specimen and its histopathological result taken by the B-type fiberscope, and recognized the better result of lavage cytology for the diagnosis of early gastric cancer.

 Authors compared with the figures of gastric cancer cells between lavage cytology and touch smear method of biopsy specimen. The formor has the tendency of the enlargement of cytoplasma, condensation of nuclear chromatin and the prominent nucleoli, but the latter the hyperchromatism.

 Authors described the effectiveness of lavage cytology with fibergastroscope to the second examination of gastric mass-survay and explained the new type of fiberscope (CS type) for lavage cytology, which has smaller diameter and easy to use for mass survay.
