Paper Abstract

Since 1981, we have been employing endoscopic Nd:YAG laser irradiation for treatment of early gastric cancer. However, the therapeutic results have not always been satisfactory. Therefore, we have developed a new Nd:YAG laser-irradiation method which uses an endoscope fitted with a transparent thin-membrane balloon at its tip. Basic studies on this balloon method confirmed that the balloon did not affect the tissue-destructive effect of the laser. In clinical studies, the balloon method was used to treat 20 lesions. The degree of efficacy (effective: negative against cancer for at least one year after treatment) was 90%. Thus, in comparison with the conventional method, the balloon method produced clearly better therapeutic results.
