  • Perspectives and possibilities of luminescent differential diagnosis in Endoscopy of Stomach ulcers
    Khirurgii︠a︡, 1999
    Co-Authors: Polsachev Vi, Alekseĭtseva Sp, Lazarev Vv, Braginskaia Ov
    Abstract:

    : On the basis of 1800 examinations of tumor cells the authors show possibility for accumulation of luminescent dye uranine by malignant cells. The conception of the mechanism of its accumulation, confirmed by the studies of reinoculated tumors of rats (60 examinations) is presented. of 821 patients with ulcers of the Stomach 641 had no luminescence; at repeated examination cancer and ulcer were revealed in 7 of them. Malignant transformation was verified by histologic method in 102 of 180 patients with luminescent ulcers. In 22 patients intestinal metaplasia was detected in the luminescence areas and in 40--there was a rough epitnelial dysplasia. At the examination of these patients two years later, cancer of the Stomach at the sites of previously revealed luminescence was detected in 15 patients (26.3%).

  • MAGNIFYING Endoscopy FOR THE DIAGNOSIS of EARLY GASTRIC CANCER
    Digestive Endoscopy, 2002
    Co-Authors: Yasumasa Niwa, Hidemi Goto, Naoki Ohmiya, Yasurou Ohtsuka, Nobuhiro Ando
    Abstract:

    Magnifying Endoscopy of Stomach cancer requires observation of minute structure and minute vessel patterns of the mucosal surface. The small pits, various-sized pits, irregularly branched pits and irregular vessels were found to be characteristics as the surface structure of early gastric cancer. Small pits were commonly observed on the differentiated type of early gastric cancer (88%) compared with the undifferentiated type (50%). We found it important to analyze not only the minute vessel patterns, but also the minute surface structure to ensure magnifying endoscopic observation using 0.1% indigo-carmine and the binarized images would be effective in determining the margin of the lesion. The relationship between the findings of magnifying Endoscopy in cancer and the histology should now be investigated. Applying the techniques mentioned above, more delicate observation in the regular Endoscopy and prudent photographing to obtain clear images might be promoted. Thus, this would contribute to Endoscopy with a concept similar to optical biopsy, and which can depend on the usual biopsy methods.
